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 intersec-
tion
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
When your vehicle is skidding
When your vehicle is steeply inclined
When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact
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.
When there is a malfunction in the system, or if the system is temporarily
unusable
“PCS” warning light will flash and warning messages will be displayed.

CAUTION
Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, tak-
ing 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-crash safety system can function
effectively. Otherwise, the system may not function correctly 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 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 Lexus 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.
Do not replace them with non-genuine parts.
Determining the direction the driver is facing and whether the driver’s eyes
are open or closed
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.

Before using the Lexus night view
Never depend on this system only.
Lexus night view is intended as a supplemental aid to help you see pedestri-
ans and road conditions ahead of the vehicle. As there are limits to the sys-
tem, do not rely solely on the system while in use, and drive safely while
observing the following precautions.
When using the Lexus night view
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
Never drive while looking at the Lexus night view screen only.
Do not look continuously at the Lexus night view screen while driving.
Pedestrians, objects etc. ahead of the vehicle may be overlooked by the
system. The system should always be used as a supplemental aid only.
Lexus night view is designed to help you see objects better when driving
in darkness on a road with few curves. Do not use the Lexus night view in
well-lit areas or on roads with many curves or slopes. There may be areas
that cannot be displayed by the system due to the road conditions (curve
size, gradient, etc.)
Lexus night view may be unable to project some features at an appropriate
level of brightness. Some or all parts of certain features may be dark or
difficult to see. Do not rely solely on the Lexus night view, and drive care-
fully while checking the surroundings for safety, as you would with a nor-
mal vehicle. Also, the following features and conditions may not be
displayed clearly.
Features that are difficult to display:
• Clothing of a pedestrian made of a certain kind of material (ex. leather
jackets)
• The characters on signs and billboards
• The information on road signs
Conditions in which display is difficult:
• Unfavorable weather conditions such as rain, fog, snowfall, snow
storms etc.
• There are large puddles of water on the road surface following rainfall
• The area of the front windshield in front of the camera is fogged up,
dirty or icy
• The areas around the headlights are covered with ice, snow, mud etc.
• The 12-volt battery voltage is remarkably low
• There are bright lights ahead of the vehicle
