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 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 battery voltage is remarkably low
• There are bright lights ahead of the vehicle

●Do not subject the camera to strong impacts, or disassemble the camera.
●As the alignment of the camera has been very finely adjusted, do not change or
remove the mounting.
●If the front windshield fogs up, defog the windshield using the front defroster.
●Do not dirty or scratch the camera lens.

Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away the
water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or on
the brakes.
●Remove any snow or mud from the bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If necessary, block the wheels to prevent inadvertent sliding or
creeping.
