switch.
The Lexus night view is displayed
on the Remote Touch screen.

: If equipped
Lexus night view is a system which assists with nighttime driving.

The image shows pedestrians, obstacles, and road conditions ahead
of the vehicle, which are difficult to see at nighttime with the
naked eye.

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

4485-1. Remote Touch screen
GS450h_300h_OM_OM30D53E_(EE)
When using the Remote Touch screen
If the screen is cold, the display may be dark, or the system may seem to be
operating slightly slower than normal.
When the screen is viewed through polarized sunglasses, a rainbow pattern
may appear on the screen due to optical characteristics of the screen. If this
is disturbing, please operate the screen without polarized sunglasses.
Dimmed screen buttons cannot be operated.
Changing between day mode and night mode
The display condition is not changed to night mode even if the headlight
switch is turned on when the vehicle is in a bright area such as daytime.
To turn off the display
The display goes off when “Screen off” is selected. To turn the screen back
on, press any button on the audio panel or on the Remote Touch. To display the screen in day mode, even
with the headlight switch on, select “Day
mode” for brightness and contrast con-
trol.
If the screen is set to day mode with the
headlight switch turned on, this condi-
tion is memorized even with the hybrid
system turned off.
NOTICE
To avoid damaging the Remote Touch screen
Wipe off fingerprints using a glass cleaning cloth. Do not use chemical
cleaners to clean the screen, as they may damage the Remote Touch screen.
