When the vehicle is almost entire ly within the target parking spot,
a high-pitched beep is emitted and the stop display is shown on
the display ( P. 459), stop the vehicle.
This completes the back-in parking assist mode.
● For safety, the buzzer sounds slightly before the vehicle is

● In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped).
● In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped). Come to a full stop so tha t the center of
the parking space is nearly perpendicular to the vehicle, and t hen operate
the S-APGS switch.
● The function cannot be used when the vehicle speed is approxima tely
19 mph (30 km/h) or higher.
● The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible ( P. 488), guidance is not issued.
● If there are no parked vehicles, the parking spot cannot be det ermined.
Therefore, the back-in parking assist mode cannot be operated.
● If unable to detect the environment surrounding the parking space, the
back-in parking assist mode may not be able to operate.
