WARNING
●Do not rely solely upon the Simple Advanced Parking Guidance 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.
● Do not back up while viewing the multi-information display. Backing up
while only viewing the monitor screen may cause a collision or lead to an
accident, as the image displayed on the monitor screen may differ from
actual conditions. Make sure to visually check the surrounding areas and
the area to the rear of the vehicle with and without the mirror while backing
up.
● 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-APGS 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 on 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-APGS switch to turn off 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.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines, 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
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact your Toyota
dealer.
● 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 your Toyota dealer.
● 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 spot. In the event that the steering
control operates, either turn the system off using the S-APGS switch or
operate 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).
