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.
● 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.
● The sensors may not be able to detect
curbs. The vehicle may drive onto the
curb depending on the situation, such
as if a vehicle in front or back of the
parking space has driven on the curb.

WARNING
●The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc., located on one side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle position greatly
differ, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when departing from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use this function
when departing from a parallel parking s pot. In the event that the steering
control operates, either turn the system off using the S-IPA switch or oper-
ate the steering wheel to stop the control.
● If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obstacle is
present, but the obstacle is not detected by the side sensors (situations
such as when the vehicle is directly beside a pole).
● Observe the following precautions, as the sensors may stop functioning
properly which may lead to an accident.
• Do not subject the sensor to strong shocks by hitting it, etc. The sen-
sors may not function properly.
• When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. Equipment may not function properly if
subjected to an impact from strong water pressure. If the vehicle
bumper strikes something, equipment may not operate properly due to
a sensor malfunction. Have the vehicle inspected at any authorized
Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer.

NOTICE
■When using the S-IPA
● Check that the parking space is suitable. (Width of the space, if there are
any obstacles, road surface condition, etc.)
● S-IPA will not operate properly if the vehicle at the front or back of the
parking space moves, or if an obstacle enters the parking space after the
sensors have detected the parking space. Always check the surrounding
area during parking assist operation.
● The sensors may not be able to detect curbs. The vehicle may drive onto
the curb depending on the situation, such as if a vehicle at the front or
back of the parking space has driven on the curb.
Check the surrounding area to prevent the tires and wheels from being
damaged.
● The vehicle may not be able to be parked at a target parking space if the
vehicle moves forward when the shift lever is in R or reverses when the
shift lever is in a position other than R, such as when parking on a slope.
● When reversing, reverse the vehicle
slowly to prevent the front end of the
vehicle from hitting an obstacle in the
front of the vehicle.
● When reversing, reverse the vehicle
slowly to prevent the front end of the
vehicle from hitting the vehicle parked in
front of the parking space.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

WARNING
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
Trailer Sway Control is part of the VSC system and will not operate if VSC
turned off or experiences a malfunction.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations.
Depending on many factors such as the conditions of the vehicle, trailer,
road surface, and driving environment, the Trailer Sway Control system
may not be effective. Refer to your trailer owner’s manual for information
on how to tow your trailer properly.
