Opinion
Plаintiff Lucille McCabe appeals from a judgment entered in a products liability action after the trial court granted summary judgment for defendants American Honda Motor Company, Incorporated, and Saturn of the Valley, Incorporated (Saturn). McCabe was injured when the driver’s side air bag in her Honda Civic failed to deploy in a frontal collision with another car. McCabe sued Honda, the air bag’s manufacturer, and Saturn, the reseller, alleging the air bag was defective in both its manufacture and its design. 1 The trial court granted Honda’s 2 motion for summary judgment, reasoning the expert declaration from a Honda engineer established that the air bag wаs not intended to inflate under the circumstances of the crash and that McCabe’s testimony that she “expected” the air bag to deploy was insufficient, without expert testimony, to raise a triable issue of material fact as to product defect.
On appeal, McCabe contends she raised triable issues of fact as to design defect under the “consumer expectation theory” and maintains the court erred in holding the consumer expectation test inapplicable as a matter of law. We agree McCabe raised triable issues of fact as to whether a driver’s side air bag, in the disputed factual context of the frontal collision at issue in this case, is the kind of product about which consumers can form minimum safety assumptions. Consequently, it was error for the trial court to conclude, as a matter of law, that the consumer expectation test was inapplicable.
Summary judgment was also improper because Honda failed to provide any evidence negating the alternative, risk-benefit theory of design defect available to McCabe. Under that alternative test, a product that causes injury may be defective in design notwithstanding its satisfaction of consumer expectations if the dеsign contains an “excessive danger” that outweighs its relative merit.
Factual and Procedural Background
On September 2, 1999, while traveling westbound in her Civic, McCabe came to a full stop in the left turn lane of a controlled intersection and waited *1117 for a break in oncoming traffic to make a left turn. According to McCabe, as the light turned yellow and she prepared to make her left turn, a Cadillac traveling eastbound at a “high speed” collided “head on” with her Civic. Although the Civic was equipped with a driver’s side air bag, the air bag did not deploy in the crash. McCabe, who suffered damage to her face and teeth in the accident when her head slammed against the steering wheel, sued Honda and Saturn, alleging the Civic’s air bag was defective in its design and/or manufacture.
A. Honda’s Motion for Summary Judgment
Honda moved for summary judgment, arguing that the air bag performed in accordance with its intended design. Honda included with its motion the 1995 owner’s manual for the Civic, advising the consumer that the air bag system is designed to inflate only “in a severe frontal collision” comparable to “a crash into a parked car at 25 [miles per hour],” and will not inflate “in a moderate frontal collision, or during a rear impact, side impact, or a roll-over even if the impact is severe.” The owner’s manual also included an illustration depicting the “frontal collision range” to span from the outside comer of one front headlight to the outside comer of the other.
Honda also included the expert declaration of Mary Christopherson, a Honda staff engineer involved in the design and testing of automotive air bags. Christopherson explained that determining whether an air bag should have deployed after a given collision required “an analysis of the angle of impact and the longitudinal deceleration experienced by the vehicle in the collision as compared with the severity of a 12 [miles per hour] full frontal impact.” According to Christopherson, the air bag is designed to deploy “when the crash sensors predict in the first moments of a collision that the deceleration of the vehicle along its longitudinal axis will be more severe than a full frontal barrier impact at or above 12 [miles per hour],” and is designed not to deploy if the “longitudinal deceleration of the vehicle is less severe than a full frontal barrier impact below 8 [miles per hour].” In addition, the “ ‘frontal collision range’ for deployment is defined as an impact with á principal direction of force that is within 30 degrees of the centerline of the vehicle. Air bags are not intended to deploy in impacts in which the principle [szc] force vector is outside the 30 degree range, unless the crash severity is so severe that the longitudinal deceleration of the vehicle exceeds the severity of a 12 [miles per hour] full frontal barrier impact.”
Christopherson reconstructed the accident based on the “physical damage to the vehicles as depicted in the photographs,” and concluded the “left front *1118 comer of the Civic made initial contact with the left front wheel area of the Cadillac” at a 35-degree frontal collision range, outside the “30 degrеe frontal collision range” required for the air bag to deploy. She determined the longitudinal component of the crash was approximately four miles per hour, “very clearly less severe” than a 12-mile-per-hour “full frontal barrier impact” in which the air bag is designed to deploy. Based on the foregoing, Christopherson opined that the air bag system performed as designed, and there was “no evidence of a defect.”
B. McCabe’s Opposition
In opposition to the summary judgment motion, McCabe maintained the Cadillac collided with her Civic “head on.” McCabe included photographs of the Civic showing extensive damage to the left front hood area and to the left side of the car and claimed the collision occurred within the frontal collision range identified in the owner’s manual. McCabe also included witness testimony, including her own and that of the Cadillac’s driver, that the Cadillac was traveling at a speed at or in excess of 35 miles per hour when it collided with her Civic. McCabe testified she purposely purchased a car with an air bag for safety reasons and expected the air bag would deploy in a high-speed head-on collision like the one in this case.
C. Honda’s Reply and the Trial Court’s Ruling
In reply, Honda observed that McCabe offered no exрert testimony refuting Christopherson’s expert opinion that the air bag performed in accordance with its intended design. Honda argued that the consumer expectation test set forth in
Barker v. Lull Engineering Co.
(1978)
The trial court granted summary judgment for Honda, reasoning that, by omitting from her opрosition any expert testimony contravening Christopherson’s declaration, McCabe had failed to produce evidence sufficient to raise a triable issue of fact as to whether the air bag should have deployed under the circumstances of this accident. The court concluded, without explanation, that the consumer expectation test, permitting a plaintiff to establish a design defect without resort to expert testimony, was inapplicable to the circumstances of this case.
McCabe filed a timely notice of appeal.
*1119 Contention
McCabe contends (1) the trial court erred in concluding the consumer expectation test for dеfective design was inapplicable under the facts of this case; and (2) under the consumer expectation test, she raised triable issues of fact as to whether the air bag’s design was defective.
Discussion
1. Standard of Review.
Summary judgment is proper where the evidence shows there is no triable issue of material fact and the moving party is entitled to judgment as a matter of law. (Code Civ. Proc., § 437c, subd. (c);
Aguilar v. Atlantic Richfield Co.
(2001)
We review the trial court’s grant of summary judgment de novo.

v.

2. Product Defect—Manufacturing Defect and Design Defect.
California recognizes two distinct categories of product defects: manufacturing defects and design defects.
(Barker, supra, 20
Cal.3d at pp.
*1120
429-430.) A manufacturing defect exists when an item is produced in a substandard condition.
(Barker,
at p. 429; see, e.g.,
Lewis v. American Hoist & Derrick Co.
(1971)
A design defect, in contrast, exists when the product is built in accordance with its intended specifications, but the design itself is inherently defective.
(Barker, supra,
The second test for design defect is known as the “risk-benefit test.” Under this test, products that meet ordinary consumer expectations
*1121
nevertheless may be defective if the design embodies an “ ‘excessive preventable danger.’ ”
(Barker, supra,
The two tests provide alternative means for a plaintiff to prove design defect and do not serve as defenses to one another. A product may be defective under the consumer expectation test even if the benefits of the design outweigh the risks.
(Curtis
v.
State of California ex rel. Dept, of Transportation
(1982)
Whether a plaintiff may proceed under the consumer expectation test or whether design defect must be assessed solely under the risk-benefit test is dependent upon the particular facts in each case.
{Soule, supra,
Some products “cause injury in a way that does not engage its ordinary consumers’ reasonable minimum assumptions about safe performance. For example, the ordinary consumer of an automobile simply has ‘no idea’ how it should perform in all foreseeable situations, or how safe it should be made against all foreseeable hazards.”
(Soule, supra,
8 Cal.4th at pp. 566-567.) In those cases, where the plaintiff’s theory of defect seeks to examine the behavior of “obscure components under complex circumstances” outside the ordinary experience of the consumer, the consumer expectation test is inapplicable; and defect may only be proved by resort to the risk-benefit analysis.
{Id.
at p. 570 [where automobile collision resulted in left front wheel breaking free, collapsing rearward and smashing floorboard into driver’s feet, it was error to instruct jury with consumer expectation test; proper test for defect is risk-benefit because behavior of obscure component parts during complex circumstances of accident not within ordinary experience of consumer];
Morson v. Superior Court
(2001)
Whether a product is within the everyday experience of ordinary consumers and thus susceptible to a consumer expectation analysis cannot be determined by looking at the product in isolation, but rather must be considered in the context of the facts surrounding its failure. The critical question is whether the “circumstances of the product’s failure permit an inference that the product’s design performed below the legitimate, commonly accepted minimum safety assumptions of its ordinary consumers.” (Soule, supra, 8 Cal.4th at pp. 568-569, italics added.) 5
*1123 3. The Trial Court Erred in Granting Summary Judgment Because Honda Failed to Demonstrate the Air Bag Was Not Defectively Designed as a Matter of Law.
Honda incorrectly maintains it met its burden of negating product defect on summary judgment by showing, through unrefuted expert testimony, that the product performed in accordance with its intended design. McCabe’s complaint alleged a defect in both the manufacture and design of the air bag. Even if Honda’s expert declaration could be viewed as having demonstrated, as a matter of law, that the аir bag performed under the circumstances of the crash in conformity with its design (a questionable conclusion considering the underlying factual dispute about the circumstances of the accident), such evidence alone is not sufficient to negate McCabe’s theory that the design itself was defective under either the consumer expectation or risk-benefit theory.
a. The Trial Court Erred in Holding the Consumer Expectation Test Inapplicable as a Matter of Law.
Relying on

v.
General Motors Corp.
(1999)
McCabe, in contrast, relying on
Bresnahan v. Chrysler Corp.
(1995)
Citing the different conclusions in

Pruitt,
both parties assert that a conflict exists and urge us to adopt the reasoning of the case more favorable to her or its respective position. In our view, the parties have incorrectly framed the issue.
Bresnahan
and
Pruitt
involved deployment of air bags under factually different scenarios. The case at bar involves the
nondeployment
of an air bag under yet another factual scenario. Deciding whether the functioning of an automobile air bag lends itself, in every circumstance, to the consumer expectation test would improperly focus on the nature of the product without regard to the circumstances of its purported failure. For example, it may be that an “[a]ir bag[] [that] inflates] for no apparent reason while one is cruising down the road at 65 miles per hour” is the kind of product failure about which consumers may form minimum safety expectations without expert opinion as to the relative merit of the design, while an air bag that deploys in a low-speed frontal collision may not be. (See, e.g.,
Pruitt
v.
General Motors Corp., supra,
In this case, drawing all inferences and resolving all conflicts in favor of the nonmoving party, we find summary judgment was improperly granted because numerous triable issues of material fact exist as to the circumstances of the accident. Relying on its expert’s “reproduction” of the accident, Honda maintains the accident occurred at a speed and at a collision range outside that required for the air bag to deploy. McCabe, on the other hand, provided evidence that the accident was a “head-on” collision, occurring within the “frontal collision range” depicted in Honda’s owner’s manual. McCabe also provided testimony that the Cadillac was traveling at a speed in excess of 25 miles per hour when it hit her Civic, the speed identified in the owner’s manual as the minimum necessary for the air bag to deploy. Moreover, although Honda based its reproduction of the accident on pictures of the automobiles after the collision, Honda’s own owner’s manual points out that “[j]ust from viewing the vehicle damage after a crash, it is very *1125 difficult to accurately determine if the air bags should or should not have inflated.” Thus, there is сonflicting evidence as to the circumstances of the accident and whether the air bag performed in accordance with the representations made in the owner’s manual.
McCabe provided sufficient evidence for a jury to infer that the nondeployment of an air bag, in the context of the high-speed, “head-on” collision described by McCabe, violates minimum safety expectations of the ordinary consumer. Indeed, the consumer expectation theory, rooted as it is in a warranty heritage (see
Barker, supra,
In reversing summary judgment, we do not hold either that the consumer expectation test applies as a matter of law or that the test was satisfied in this case. In putting forth its own version of the accident, the defense will be free to argue to the fact finder that the consumer expectаtion test is not applicable in this case because the performance of the air bag
in this type of collision
is not the type of product performance about which consumers may have reasonable minimum safety expectations. (See
Bresnahan
v.
Chrysler Corp.
(1998)
*1126 b. Honda Failed to Negate Design Defect Under the Alternative Risk-benefit Test.
Honda’s summary judgment motion fails for another reason. A claim of design defect may be proved under the consumer expectation theory (if applicable) or the risk benefit theory. The tests are not mutually exclusive, and a plaintiff may proceed under either or both. (Barker,
supra,
Honda argues it was not required to negate the risk-benefit theory because McCabe elected not to proceed under that theory. Honda points to discovery
*1127
responses in which McCabe identified her own “expectation” that the air bag would deploy as the basis for finding a design defect and notes that McCabe never cited “risk-benefit” evidence. Contrary to Honda’s contеntion, it is not McCabe’s obligation or burden to cite “risk-benefit” evidence. That burden belongs to Honda.
(Barker, supra,
20 Cal.3d at pp. 431-432;
Soule, supra,
Disposition
The judgment is reversed. The matter is remanded for further proceedings not inconsistent with this opinion. McCabe is to recover her costs on appeal.
Lillie, P. J., and Johnson, J., concurred.
Notes
McCabe also sued Corine Louise Madrid, the driver of the other vehicle. Madrid was not a party to the summary judgment motion and is not a party to this appeal.
Satum filed a notice of joinder in Honda’s summary judgment motion.
An exception exists where the product is in specialized use with a limited group of consumers. In such cases, “if the expectations of the product’s limited group of ordinary consumers are beyond the lay experience common tо all jurors, expert testimony on the limited subject of what the product’s actual consumers
do expect
may be proper.”
(Soule, supra,
This footnote has been the subject of extensive debate among commentators. Some have suggested that in including this footnote the Supreme Court effectively limited the consumer expectation test to fact situations lending themselves to a res ipsa loquitur-type analysis. (See Henderson & Twerski, Achieving Consensus on Defective Product Design (1998) 83 Cornell L.Rev. 867, 899-900.)
The inherent complexity of the product itself is not controlling. For example, a complex product may perform “so unsafely” in a particular circumstance “that the defect is apparent to the common reason, experience, and understanding of its ordinary consumers.”
(Soule, supra,
Honda insists the owner’s manual is not evidence of “consumer expectation” because McCabe admits she did not rely on it in forming her expectation of the air bag’s performance in frontal collisions. Whether McCabe actually relied on the owner’s manual in fоrming her expectation is irrelevant. The consumer expectation test considers the “expectations of a hypothetical reasonable consumer, rather than those of the particular plaintiff in the case.”
(Campbell
v.
General Motors Corp., supra,
In a jury case, the trial court must initially determine, as a question of foundation and in the context of the facts and circumstances of the particular case, whether the product is one
*1126
about which the ordinary consumer can form reasonable minimum safety expectations.
(Soule, supra,
8 Cal.4th at pp. 568-569.) If the court concludes it is not, no consumer expectation instruction should be givеn. (See
Pruitt v. General Motors Corp., supra,
72 Cal.App.4th at pp. 1483-1484.) If, on the other hand, the trial court finds there is sufficient evidence to support a finding that the ordinary consumer can form reasonable minimum safety expectations, the court should instruct the jury, consistent with Evidence Code section 403, subdivision (c), to determine whether the consumer expectation test applies to the product at issue in the circumstances of the case and to disregard the evidence about consumer expectations unless the jury finds that the test is applicable. If it finds the test applicable, the jury then must decide whether the product failed to perfоrm as safely as an ordinary consumer would expect when the product is used in an intended or reasonably foreseeable manner.
(Soule, supra,
„ In leaving the question of the applicability of the consumer expectation test for the trier of fact, we envision an inquiry similar to that employed in res ipsa loquitur cases. (See Pruitt v. General Motors Corp., supra, 12 Cal.App.4th at p. 1484 [consumer expectation test reserved for “res ipsa-like cases that do not require the application of a general standard to determine defective design,” citing Henderson & Twerski, Achieving Consensus on Defective Product Design, supra, 83 Cornell L.Rev. 867, 899-900].) In res ipsa cases, there must be some evidence that would supрort a finding of the existence of the three conditions necessary for the application of the res ipsa presumption before the instruction is given. (See com. to BAJI No. 4.00 (8th ed. 1998), p. 110 [“Whenever the evidence can be said to be conflicting or subject to different inferences, it is a question of fact whether the conditions exist necessary to bring into operation the doctrine of res ipsa loquitur and the question must be submitted to the jury under proper instructions”].)
BAJI No. 9.00.5 provides in part: “A product is defective in design: [^] [if it fails to perform as safely as an ordinary consumer would expect when used in an intended or reasonably foreseeable manner] [or] [1[| [if there is a risk of danger inherent in the design which outweighs the benefits of that design].”
