■ Tips for using the perpendicular parking assist mode
● The vehicle can be parked in a parking
space between 2 vehicles and a space
behind a parked vehicle.
Leave a gap of approximately 1 m (3.3 ft.)
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 vehicles.

■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 be
not be able to operate depending on the surrounding environment.
NOTICE
● The detection range of the sensors (P. 413) is limited. Directly confirm
the safety of your surroundings, and if there is a possibility of a contact
accident, stop the vehicle 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.
● When departing for a position from which you can take off, directly confirm
the safety of your surroundings.

WARNING
●Do not rely solely upon the Simple Intelligent Parking Assist System. As
with unequipped vehicles, move forward and back up carefully while
directly confirming the safety of your surroundings and the area to the rear
of the vehicle.
● The sensor detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
● Drive slowly while adjusting your speed by depressing the brake pedal
when backing up or moving forward.
● If it seems the vehicle may make contact with a pedestrian, another vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-IPA switch to turn off the system.
● Use the system in a parking lot with a flat surface.
● Observe the following precautions, as the steering wheel automatically
turns during use.
• There is risk of a necktie, scarf, your arm, etc., being caught up in the
steering wheel. Please do not allow your upper body to be close to the
steering wheel. Also, do not allow children close to the steering wheel.
• There is a possibility of injury when the steering wheel turns if you have
long fingernails.
• In case of an emergency, stop the vehicle by depressing the brake
pedal, and then press the S-IPA switch to turn off the system.
● Always confirm that there is appropriate space before attempting to park
the vehicle and operate the system.

WARNING
●Do not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking spot and may
lead to an unexpected accident.
• On sharp bends
• During bad weather such as heavy rain, fog, snow, or a sandstorm
• When the tires slid while attempting to park
• When fallen leaves or snow has accumulated in a parking space
• When items such as a towing bracket, trailer, bicycle carrier, etc., are
installed on the rear of the vehicle
• When a vehicle, where the front/rear end is above the detection area
such as a truck or bus, or vehicle with a towing bracket, trailer, bicycle
carrier, etc., is parked at the front or rear of the parking space
• If the sensor is covered by the front bumper cover, etc.
• If a vehicle or obstacle is not in a suitable position at the front or rear of
the parking space
• In an area that is not a parking lot
• A parking lot that is not paved, such as a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parking spot
• Using tire chains or compact spare tire (if equipped)
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

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.

WARNING
●In the following situations, the sensors may not operate normally and may
lead to an accident. Drive carefully.
• Obstacles cannot be detected in the side areas until a scan of the side
areas is completed. ( P. 415)
• Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot
be detected.
• The sensor is frozen (if it thaws, the system returns to normal).
A warning message may display at particularly low temperatures due to
the sensor freezing and it may not detect parked vehicles.
• The sensor is blocked by someone’s hand.
• The vehicle is tilted a large amount.
• The temperature is extremely hot or cold.
• The vehicle is driven on undulating roads, slopes, gravel roads, in areas
with tall grass, etc.
• An ultrasonic wave source is nearby, such as the horn or sensors of
another vehicle, a motorcycle engine or the air brake of a large vehicle.
• Heavy rain or a water strikes the vehicle.
• Do not install any accessories within the sensor detection range.

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.
