■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 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 en d 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-collision system
When a malfunction occurs due to sensor co ntamination, etc. that results in the sen-
sors 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.
■When there is a malfunction in the system
The pre-collision system warning light will flash and warning messages will be dis-
played. ( P. 495, 503)

CAUTION
■Limitations of the pre-collision system
Do not overly 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.
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively.
Otherwise, the system may not function co rrectly and could result in an accident.
●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 surr ounding 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 th e sensor and grille cover.
●Do not replace them with non-genuine parts.
■Handling the camera sensors (if equipped)
Observe the following to ensure that the PCS functions effectively:
●Keep the windshield clean at all times.
PCS effectiveness may be reduced due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not subject the camera sensor to a strong impact or force, and do not disas-
semble the camera sensor.
●Do not change the installation position of the camera sensor, or remove and rein-
stall it. The direction of the camera sensor is precisely adjusted.
●When the windshield fogs up, use the windshield defogger to dry the windshield.
During cold weather, using the heater with air blowing to the feet may allow the
upper part of the windshield to fog up, having a negative effect on the images.
●Do not place anything on the dashboard.
Images reflected on the windshield may reduce the effectiveness of the camera
sensor.
●Do not scratch the camera lens, or let it get dirty.
●Do not attach a sticker or other items to the windshield near the camera sensor.

CAUTION
■Headlights (vehicles with camera sensors)
●Observe the following to ensure proper near-infrared ray projection:
• Keep the headlights clean at all times.
• The detection performance may deteriorate if the high beams are misaligned
or inoperative.
●The near-infrared ray transmitters projec t strong energy that is not visible.
Although the transmitters normally turn off when the vehicle is stopped, never
look into the headlights for your safety.
■Determining the direction the driver is facing and whether the driver’s eyes are
open or closed (vehicles with driver monitor system)
The direction the driver is facing and whether the driver’s eyes are open or closed
may not be determined correctly if the following conditions exist:
●There is an object between the driver monitor sensor and the driver’s face, such
as when the sensor is blocked.
●A part of the driver’s face is covered.
●The sensor or the driver’s face is exposed to intense light such as sunlight.
●The driving posture is improper.
●The vehicle is parked.
■Handling the driver monitor sensor (vehicles with driver monitor system)
Observe the following to ensure the driver monitor sensor can function effectively.
Failure to do so may result in a malfunction or may prevent the system from cor-
rectly determining the direction the driver is facing and whether the driver’s eyes
are open or closed, resulting in an unexpected accident.
●Do not disassemble, damage, lift or pull on the sensor.
●Do not select the sensor while driving.
●Do not wet or spill water on the sensor.
●Do not drop anything on or allow anythi ng to hit against the sensor. Do not sub-
ject the sensor to an impact.
●Make sure that there are no scratches, dirt or stickers on the side of the sensor
that faces the driver.
●Do not place any objects in front of the si de of the sensor that faces the driver or
cover the sensor.

CAUTION
■Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision 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-collision system is only able to detect obstacles directly in front of the
vehicle, and only within a lim ited 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-collision system is that from ob stacles 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 situ-
ation.
●Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help reduce the
severity of a collision, and so only acts wh en the system has judged that a collision
is unavoidable. This system by itself is not capable of automatically avoiding a col-
lision or bringing the vehicle to a stop sa fely. For this reason, when encountering a
dangerous situation 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 dampen ed 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.

sages will be displayed: ( P. 5 0 3 )
●There is a malfunction with the sensors
●The sensors have become dirty
●The outside temperature is extremely high or low
●The sensor voltage has become abnormal
