*269 Opinion
Defendant Karen Arnetta Scott appeals from judgment entered after a jury found her guilty of being an accessory to robbery (Pen. Code, § 32). On appeal, defendant contends that (1) the trial court erred in failing to give CALJIC No. 17.01, sua sponte, to the jury; (2) the jury was improperly instructed that defendant could be convicted as an accessory rather than as a principal; and (3) the evidence is insufficient to support the jury’s verdict. We affirm.
I
Steven Jackson, defendant’s brother-in-law, robbed a Barclay’s Bank in San Mateo. As Jackson walked toward the door with the money, Susan Williamson, the teller, screamed out that she had been robbed. James Davis, the only other customer in the bank at the time, followed Jackson out of the door. He saw Jackson, who was walking “very fast,” get in a red Volkswagen driven by a black female.
Detective Sergeant William Pollett, who had heard the radio broadcast describing the robbery and getaway car, got into an unmarked police car with two other detectives. As they headed toward the bank, a red Volkswagen, going in the opposite direction, passed them. Sergeant Pollett made a U-turn, followed the car and with other police assistance stopped the car. Jackson raised his hands to indicate surrender and maintained that position until he got out of the car. Defendant got out first, followed by Jackson. After arresting defendant and Jackson, Sergeant Pollett found a woman’s purse with a large amount of money spilling out of it between the front bucket seats of the car. There was also some money on the floor to the rear of the purse. In addition to the money, the purse contained makeup and identification belonging to defendant.
Defendant denied knowing anything about the robbery. She testified that she was planning to leave for an appointment at a drop-in health clinic in San Mateo when Jackson came to her house and asked for a ride. She agreed to give Jackson a ride because he also wanted to go to San Mateo. Following Jackson’s directions, defendant parked in front of an apartment building; Jackson left and defendant waited for his return. Although she had parked just down the street from the bank, defendant stated that she did not see Barclay’s Bank and did not know a bank was located on the corner. Jackson returned in about five minutes, “looked behind him and he raised up the front car seat and he jumped in the back,” and closed the door. He laid down in the back seat and told defendant to make a U-turn and to take off in a hurry because he had been in a fight and the police were going to be *270 looking for him. Defendant testified that she was confused by Jackson’s actions, but complied with his directions because she was afraid of him from his tone of voice. Both he and her husband, from whom she was separated, were violent men. Defendant conceded that Jackson’s actions made her suspicious and she believed that more than a fight was involved. Despite Jackson’s protests, defendant stopped as soon as she saw Oflicer Sharka’s red lights because she had never been arrested before and did not want to get into trouble.
In rebuttal, the prosecution called Officer Prudhel who had interviewed defendant about an hour after her arrest and played portions of a taped statement she had made. Although the portions of defendant’s statements played for the jury were not reported in the record, her postarrest statement contradicted her testimony that she did not know a bank was on the corner of the street where she had parked and that she had never seen any money.

Defendant contends that the trial court erred in failing to instruct the jury, sua sponte, with CALJIC No. 17.01, which requires jury unanimity on the act or acts forming the basis of the conviction.
Even in the absence of a request, a trial court has a duty to instruct on general principles of law closely and openly connected with the facts before the court and which are necessary for the jury’s understanding of the case.

v.
Freeman
(1978)
In the information filed by the prosecutor, defendant was charged with alternative counts, being either an aider and abettor to robbery or an accessory after the fact. The jury was instructed that defendant could be found guilty of one or the other, but not both; in the same instruction, the jury was told, “[Y]ou must all agree as to the particular offense committed . ...” To find defendant guilty of robbery, the jury had to consider
all
of defendant’s acts from the time she gave Jackson a ride to San Mateo until they were stopped by the police. To find defendant guilty of being an accessory, the jury had to consider the
same
acts, but had to reject any inference of an intent to rob or to facilitate the robbery from those acts. In effect, the only offense charged was the one proved, a situation to which the rule requiring jury unanimity on the act or acts of which defendant is convicted
*271
is not applicable. (See
People
v.
Madden
(1981)
The trial court had no duty to instruct the jury with CALJIC No. 17.01. Our conclusion would be no different even if defendant had identified the various acts from which the prosecutor had to elect one for the jury to use as the basis of conviction. Defendant’s participation as an accessory simply did not involve separate acts in any real and practical sense. (See

v.
Ruiz

Defendant contends that the jury was improperly instructed that she could be convicted of being an accessory because the robbery was still in progress when she drove Jackson away from the bank. Despite the People’s contention that defendant waived any error by failing to object at trial, this court “may review any instruction given even though no objection was made in the lower court if the substantial rights of the defendant are affected [citations].”

Instead of being convicted of the more serious offense of robbery, defendant was guilty of the less serious charge of accessory.

does not stand for the proposition that the continuous nature of a robbery precludes conviction for a less serious offense. The rule that a robbery continues until the perpetrator reaches a place of temporary safety and is in unchallenged possession of the stolen property has traditionally been used to establish liability for a
more serious offense
in felony-murder and kidnaping-for-robbery cases. (See

Liability as an accessory attaches when, among other elements, the principal has committed a specific completed felony. (See
