NOTICE
●If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an angle or may
deviate from the parking spot. In these cases, do not use the parallel park-
ing assist mode.
● When there is a wall or other obstacle on the inner side of the parking
space, or when another parked vehicle extends into the road from its park-
ing spot, the target parking spot may be set in a position that juts out
slightly into the road.
● Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehicle alignment as necessary.
● The system provides assistance to guide the vehicle based on position of
adjacent vehicles, even if there are obstacles, bumps, drops or curb
stones in the parking space.
If it seems the vehicle may make contact, stop the vehicle by depressing
the brake pedal, and then press the S-APGS switch to turn off t he system.
● It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.
●When the other parked vehicle is nar-
row or parked extremely close to the
curb, assist control will also guide the
vehicle to a position close to the curb.
If it seems the vehicle may make con-
tact with the curb or any other obsta-
cles, or if it seems the tire position will
deviate from the intended parking spot,
stop the vehicle by depressing the
brake pedal, and then press the
S-APGS switch to turn off the system.
