■Parallel parking assist mode operating conditions
●In order to operate the parallel parking assist mode correctly, drive slowly (at
a speed at which the vehicle can be quickly stopped) parallel to the road (or
shoulder) while maintaining a distance of approximately 1 m (3.3 ft.) to any
parked vehicles.
●The function cannot be used when the vehicle speed is approximately
30 km/h (19 mph) 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. 557), guidance is not issued.
●If there are no parked vehicles, the parking spot cannot be determined.
Therefore, the parallel parking assist mode cannot be operated.
●If unable to detect the environment surrounding the parking space, the par-
allel parking assist mode may not be able to operate.
●Guidance will continue until the vehicle speed meets or exceeds approxi-
mately 30 km/h (19 mph) or the function is turned off using the S-IPA switch.
■Timing for pressing the S-IPA switch
In the following cases, the assist mode may also operate during the steps
taken to park using the parallel parking assist mode. However, in these
cases, conduct parking procedures according to the information on the multi-
information display.
●In step the S-IPA switch is pressed after already passing over the target
parking spot.
If the vehicle is not stopped in step , pressing the S-IPA switch 1 time
while the vehicle is in motion allows you to select “Parallel Parking” and
proceed directly to step .
●The vehicle is moved up to the position in step without the S-IPA switch
being pressed. Then the S-IPA switch is pressed after having changed the
shift position to R.

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 vehi cle 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-IPA switch to turn off the 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-IPA
switch to turn off the system.

■Exit parallel parking assist mode
● During assist control, if the driver determines that they are at a position
where take-off is possible and operates the steering wheel, assist control is
stopped at that position.
● Assist control cannot be used if there are no parked vehicles ahead, or if the
gap between the front of your vehicle and the vehicle parked ahead is too
large.
● When using the exit parallel parking assist mode, the assist mode may not
be able to operate depending on the surrounding environment.
