ADVANCED PARKING GUIDANCE SYSTEM - Parking assist mode (Perpendicular parking) Parking assist mode assists the driver with perpendicular parking by automatically controlling the steering wheel when backing up, in order to park in the target position set on the screen. PRE−SUPPORT FUNCTION The pre−support function can be used when another vehicle is parked on the near side of the intended parking space. This function uses a tone to give parking guidance. Guidance will not be given if the detected space is narrow. Parking on the next side of another parked vehicle CAUTION D When backing up, be sure to check your surroundings and behind the vehicle for safety, and back up slowly, depressing the brake pedal to control vehicle speed. D If you seem likely to hit nearby vehicles, obstacles or people, depress the brake pedal to stop the vehicle, then disable the system by touching on the screen. As the system only assists with parking in a set target parking position, there are times when the system will be unable to render this assistance, depending on factors such as road surface or vehicle condition, or the distance to the set target parking position. Use the system with full understanding of the fact. If a message is displayed while maneuvering, follow the procedures outlined in "- What to do when this sort of message is displayed" on page 243. The illustrations here describe the procedure for pulling into a parking space on the right. For pulling into a parking space on the left, substitute left for right and vice versa in all steps. The operating method differs depending on whether or not the pre−support function is in use.
