road width (distance to the side
of the road across from the park-
ing space) is narrow, or if there
are obstacles in front of the vehi-
cle, guidance will not be issued.
Parking is complete
This completes the assist mode.
Depending on the condition of the parking space, guidance to st arting
points for moving forward and backing up, as well as the steeri ng wheel

● 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.

■Tips for using the back-in parking assist mode ●Depending on the condition of the park-
ing space, if there is not enough space
in front of the vehicle required to perform
the parking operation, the target parking
spot may not be reachable.
Intended parking spot
Wall
● Leave a gap of approximately 3.3 ft. (1
m) from any parked vehicles and
approach the target parking spot. If the
gap between your vehicle and any
parked vehicles is too large, the front
side sensors and rear side sensors may
not be able to detect the parked vehi-
cles.
● Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-APGS
switch when the vehicle is at a complete
stop.
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 back-in park-
ing assist mode.
● When parking in a narrow space, the vehicle will come close to adjacent
vehicles. If it seems the vehicle may make contact, stop the ve hicle by
depressing the brake pedal.
● 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.
● 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.
