The “PCS” warning light will turn
on when the pre-crash braking is
disabled.
Radar sensor
Detects vehicles or other obsta-
cles on or near the road ahead
and determines whether a colli-
sion is imminent based on the
position, speed, and heading of
the obstacles.

Obstacles not detected
The sensor cannot detect plastic obstacles such as pylons. There may also
be occasions when the radar sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
The pre-crash safety system is operational when
Pre-crash seat belts (Type A):
• Vehicle speed is greater than about 30 km/h (19 mph).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
Pre-crash seat belts (Type B):
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
Pre-crash brake assist:
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.
Pre-crash braking:
• The pre-crash braking OFF switch is not pressed.
• Vehicle speed is greater than about 15 km/h (10 mph).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 15 km/h (10 mph).

Situations in which the pre-crash safety system does not function
properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When the axis of the radar is out of adjustment
When an extreme change in vehicle height occurs
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 616)
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system
will be automatically disabled. In this case, the system will not activate even
if there is a collision possibility.

CAUTION
Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function
effectively.
Keep the sensor and grille cover clean at all time.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
Do not subject the sensor or surrounding area to a strong impact. 
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
Do not modify or paint the sensor and grille cover.
Limitations of the pre-crash safety system
Do not rely on the pre-crash safety system. Always drive safely, taking care
to observe your surroundings and checking for any obstacles or other road
hazards. 
Failure to do so may cause an accident resulting in death or serious injury.

510 4-1. Maintenance and care
AVENSIS_OM_OM20B88E_(EE)
CAUTION
Caution about the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
When cleaning the windshield (vehicles with rain-sensing windshield
wipers)
When the upper part of the windshield where the raindrop sensor is
located is touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.
