NOTICE
■KDSS
In the following situations, there is the possibility that a system malfunction
has occurred, and drive comfort and the vehicle’s ability to travel on poor
road surfaces may be reduced. Take the vehicle to your Toyota dealer imme-
diately.
●When turning a corner, the vehicle’s body seems to roll further than nor-
mal.
●If after the vehicle has been left in a slanted position for a long time, for
example with the wheels of one side parked on a curb, the vehicle does
not return to level when driving (the vehicle remains slanted to one side
after returning the vehicle to level ground).

Pre-Collision System
: If equipped
When a frontal collision seems likely, the system attempts to lessen
vehicle’s damage. Two types of pre-collision system are available.
The brake-linked pre-collision system operates in conjunction with
the braking operation of the driver. The radar type pre-collision sys-
tem has a sensor that is used to detect an unavoidable frontal colli-
sion.
■Pre-collision seat belts (front seats only)
Brake-linked pre-collision system
Based on the speed and amount of the driver’s braking operation, the
system determines if emergency braking is being performed. If this
determination is made, the seat belts are immediately retracted to
increase the effectiveness of the pretensioners (P. 80). In addition,
the system also operates if the driver loses control of the vehicle.
Radar type pre-collision system
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 80)
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision brake assist (Radar type only)
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.

Radar sensor (Radar type only)
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.
When traveling on a road with very light traffic and very little to reflect the
radar waves emitted by the radar sensor, the system may decide that the
radar sensor is dirty, even if the sensor is not actually dirty. The system will
automatically restore itself when reflected radar waves are detected.

■Obstacles not detected (Radar type only)
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-collision system is operational when
●Pre-collision seat belts (situation 1)
• Vehicle speed is greater than about 4 mph (5 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The front occupants are wearing a seat belt.
●Pre-collision seat belts (situation 2)
• Vehicle speed is greater than about 19 mph (30 km/h).
• The system detects sudden braking or skidding.
• The front occupants are wearing a seat belt.
●Pre-collision brake assist
• Vehicle speed is greater than about 19 mph (30 km/h).
• The speed at which your vehicle is approaching the obstacle or the
vehicle running ahead of you is greater than about 19 mph (30 km/h).
• The brake pedal is depressed.

■Conditions that may trigger the system even if there is no possibility of
collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
●When climbing a steep hill causes an overhead billboard or other metallic
structure to appear directly in the vehicle’s line of travel
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
When the system is activated in the situations described above there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 606, 617)

■Situations in which the pre-collision 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 such as the VSC system off
●When your vehicle is steeply inclined
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision 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 (Radar type only)
Observe the following to ensure the pre-collision system can function effec-
tively.
●Keep the sensor and front grille clean at all times.
Clean the sensor and front grille 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 are subject to
a strong impact, always have the area inspected and adjusted by your
Toyota dealer.
●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.
■Limitations of the pre-collision system
Do not rely on the pre-collision 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.
