■ Sensor detection information
● Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicl es, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelet is installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Toyota suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
● The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angles objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle

NOTICE
■ Cleaning detergents
● Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
● Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
● Remove any dust or dirt on leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
■ When cleaning the inside of the windshield (vehicles with front sensor)
Be careful not to touch the front sensor ( P. 263, 266). If the camera is acci-
dentally scratched or hit, PCS (Pre-Collision System), LDA (Lane Departure
Alert) and Automatic High Beam may not operate properly or may cause a
malfunction.
■ Cleaning the inside of the rear window
● Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires. Use a cloth dampened
with lukewarm water to gently wipe the window clean. Wipe the window in
strokes running parallel to the heater wires.
● Be careful not to scratch or damage the heater wires.

5-2. Steps to take in an emergency
When trouble arises
VERSO_EE_OM64590E
Follow the correction procedures.
After taking the specified steps to correct the suspected problem,
check that the warning light turns off.
Warning lightWarning light/DetailsCorrection procedure
PCS (Pre-Collision Sys-
tem) warning light (if
equipped)
When the warning light
flashes (and a buzzer
sounds):
Indicates a malfunction in
the PCS (Pre-Collision Sys-
tem)
Have the vehicle inspected
by any authorized Toyota
dealer or repairer, or
another duly qualified and
equipped professional
immediately.
When the warning light
flashes or illuminates (and a
buzzer does not sound):
Indicates that the PCS (Pre-
Collision System) is tempo-
rarily unavailable, possibly
due to either of the follow-
ing:
• The part of the windshield
around the front sensor
being dirty, fogged up or
covered with condensation,
ice, stickers, etc.
• Front sensor temperature
being outside of its opera-
tional range.
• Clear the dirt, fog, conden-
sation, ice, stickers, etc.
( P. 265)
• Wait for a while until the
area around the front sen-
sor has cooled down suffi-
ciently.
When the warning light is
illuminated:
Either the VSC (Vehicle Sta-
bility Control) system or
PCS (Pre-Collision System)
is disabled or both are dis-
abled.
To enable the PCS, enable
both the VSC system and
PCS. ( P. 269, 313)

5-2. Steps to take in an emergency
VERSO_EE_OM64590E
■ Front passenger detection sensor and passenger seat belt reminder
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■ When the tire pressure warning light comes on (vehicles with a tire
pressure warning light system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 560, 577
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
(vehicles with a tire pr essure warning light system)
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pressure changes caused by temperature.
In this case, adjusting the tire inflation pressure will turn off the warning light
(after a few minutes).
■ When a tire is replaced with a spare tire (vehicles with a tire pressure
warning light system)
The spare tire is not equipped with a tire pressure warning valve and trans-
mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced wi th the spare tire. Replace the spare
tire with the repaired tire and adjust the tire inflation pressure. The tire pres-
sure warning light will go off after a few minutes.
