■The pre-crash safety system is operational when
●Pre-crash warning:
Vehicles without camera sensors
• 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 run-
ning ahead of you is greater than about 15 km/h (10 mph).
Vehicles with camera sensors
• The pre-crash braking off switch is not pressed.
• Vehicle speed is greater than about 5 km/h (4 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle run-
ning ahead of you is greater than about 5 km/h (4 mph).
●Pre-crash seat belts (operating conditions 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 (operating conditions 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 run-
ning ahead of you is greater than about 30 km/h (19 mph).
• The front occupants are wearing a seat belt.
●Pre-crash brake assist:
• The VSC OFF switch is not pressed.
• Vehicle speed is greater than about 30 km/h (19 mph).
• The speed at which your vehicle is approaching the obstacle or the vehicle run-
ning ahead of you is greater than about 30 km/h (19 mph).
• The brake pedal is depressed.

■Conditions that may trigger the system even if there is no danger of a collision
In any of the following situations where the frontal area of the radar sensor is inter-
rupted, the radar sensor may detect possibility of a frontal collision and the system
may be activated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the left.
●When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate bar-
rier, etc.)
●When there is a structural object (billboard, low ceiling, fluorescent light, etc.)
above the uphill road ahead
●When driving on a narrow road or through under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle front part is raised or lowered depending on loading conditions
●When the direction of radar sensor is misaligned by strong impact applied on an
area around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a
curve
●When the front of your vehicle is pointing upwards (caused by putting a heavy load
in the trunk etc.)
●When driving through an area filled with steam or smoke
When the system is activated in the situatio ns described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes may 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 it.
■Obstacles not detected
The radar sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicycles,
motorcycles, trees, or snowdrifts.
■A camera sensor cannot detect obstacles in the following situations:
●A camera sensor is directly receiving intense light, such as sunlight.
●Visibility is poor because of bad weather or other reasons.
●The sensor temperature is extremely high.
●The headlights are not turned on in darkness such as at night or in a tunnel.

■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 intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●If the vehicle is skidding when VSC is not operating
●When an extreme change in vehicle height occurs
●When only part of your vehicle’s front end collides with, or contacts, a vehicle or
object in a frontal collision
●When the radar sensor moves off position due to its surrounding area being sub-
jected to a strong impact
●If an obstacle in front of the vehicle is small
●When the system judges that the driver performed a collision avoidance operation
via the accelerator pedal, brake pedal, or steering wheel
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sen-
sors being unable to detect obstacles, the pre-crash safety system will be automati-
cally disabled. In this case, the system will not activate even if there is a collision
possibility.
■When there is a malfunction in the system
The pre-crash safety system warning light will flash and warning messages will be
displayed. ( P. 607, 614)

CAUTION
■Limitations of the pre-crash safety system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
Do not use the pre-crash safety system instead of normal braking operations under
any circumstances. This system will not prevent collisions or lessen damage or inju-
ries in all cases. Do not overly rely on this system. Failure to do so may cause an
accident, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of collisions.
However, the system operates differently depending on the situation ( P. 372,
374). As a result, the same level of performance may not be expected in all cases.
Also, the pre-crash safety brakes may not operate if the driver is depressing the
brake pedal or turning the steering wheel, as the system will determine such condi-
tions as collision avoidance operations.
■Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effec-
tively. Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor and grille cover clean at all times.
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 malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●If the radar sensor needs to be replaced, contact your Lexus dealer.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is intended to
assist the driver in avoiding collisions through the process of LOOK-JUDGE-ACT.
There are limits to the degree of assistance the system can provide, so please keep
in mind the following important points.
●Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in front of the
vehicle, and only within a limited range. It is not a mechanism that allows careless
or inattentive driving, and it is not a system that can assist the driver in low-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle’s surroundings.
●Assisting the driver in making correct judgment
When attempting to estimate the likelihood of a collision, the only data available
to the pre-crash safety system is that from obstacles it has detected directly in
front of the vehicle. Therefore, it is absolutely necessary for the driver to remain
vigilant and to determine whether or not there is a possibility of collision in any
given situation.
●Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help reduce
the severity of a collision, and so only acts when the system has judged that a col-
lision is unavoidable. This system is not capable of automatically avoiding a colli-
sion or bringing the vehi cle to a stop safely without appropriate operations
performed by the driver. For this reason, when encountering a dangerous situa-
tion the driver must take direct and immediate action in order to ensure the safety
of all involved.
NOTICE
■Precautions for cleaning the driver monitor sensor (vehicles with driver monitor
system)
●Gently wipe the sensor with a soft cloth to prevent damage.
●Wipe any excess dirt with a cloth dampened with neutral detergent, all liquids
having been wringed out of the cloth. After that, wipe again with a dry cloth.
●Do not use benzene, thinner, glass cleaners, wax, etc.
