The camera sensors detect pedestrians and other three-dimensional
objects on or near the road ahead together with the radar sensor while
the vehicle is moving.
When the headlights are on, near-infrared rays are projected to ensure
proper detection performance in the night time.
Camera sensors
Near-infrared ray transmitters
The driver monitor sensor detects
the direction the driver is facing and
whether the driver’s eyes are open
or closed.
The system determines whether the
driver is facing forward and whether
or not the driver’s eyes are closed.

■Conditions that may trigger the system even if there is no danger of a 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
●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 there is a metal plate in the road in front of the vehicle on a downhill slope
●When climbing a steep hill causes an overhead billboard or other metallic structure
to appear directly in the vehicle’s line of travel
●When driving under an overpass
●When an extreme change in vehicle height occurs
●When passing through certain toll gates
●When driving through a lump of steam or smoke
●When the radar sensor moves off position due to its surrounding area being sub-
jected to a strong impact
When the system is activated in the situations described above, there is also a possi-
bility 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 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 dark ness such as at night or in a tunnel.

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.

headlights are on.
Lexus night view
: If equipped
Lexus night view is a system which assists with nighttime driving.
Near-infrared rays are irradiated forward and an image converted
from the irradiated light is sh own on the Remote Touch screen. The
image shows pedestrians, obstacles, and road conditions ahead of the
vehicle, which are difficult to see at nighttime with the naked eye.

CAUTION
■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 pedestrians and
road conditions ahead of the vehicle. As there are limits to the system, 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. Pedestri-
ans, objects etc. ahead of the vehicle may be overlooked by the system. The sys-
tem should always be used as a supplemental aid only.
●Lexus night view is designed to help you see objects better when driving in dark-
ness 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 dis-
played 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 carefully while checking the
surroundings for safety, as you would with a normal 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 certai n 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 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
