In the following situations, the warning light will turn off, the message will disappear and
the system will become operational when normal operating conditions return:
• When the radar sensor or ca mera sensor or the area around either sensor is hot,
such as in the sun
• When the radar sensor or camera sensor or the area around either sensor is cold,
such as in an extremely cold environment
• When a front sensor is dirt y or covered with snow, etc.
• When the part of the windshield in front of the camera sensor is fogged up or cov-
ered with condensation or ice (Defogging the windshield:  P. 411)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is
attached to the windshield near the camera sensor ●
If the PCS warning light continues to flash or remains illuminated or the warning mes-
sage does not disappear even though the vehicle has returned to normal, the system
may be malfunctioning. Have the vehicle in spected by your Lexus dealer immediately.■

LDA (Lane Departure Alert) When driving on roads with white (yellow) lines, this function alerts the driver
when the vehicle might depart from its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the front
windshield.
◆ Lane departure alert function
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver. When the warning buzzer sounds or
the steering wheel vibrates, check
the surrounding road situation and
carefully operate the steering wheel
to move the vehicle back to the cen-
ter of the lane.

Multi-terrain Monitor
The following screens can be select ed according to driving conditions.
• Screens that can be selected vary depend ing on conditions such as shift posi-
tion and vehicle speed. (  P. 328)
• Depending on the displayed screen, the display can be switched from normal
to wide view display.The Multi-terrain Monitor helps the driv er to check the vehicle surroundings.
It assists in determining the conditions around the driver in a variety of situa-
tions, such as when judging conditions during off-road driving or checking for
obstacles when parking. WARNING ■
When using the Multi-terrain Monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries. ●
Never rely solely on the Multi-terrain Monitor. As with unequipped vehicles, drive
carefully while directly confirming the safety of your surroundings and the area to the
rear of the vehicle. Take particular care to avoid parked cars and other obstacles.●
Due to the characteristics of the camera lens, the actual position and distance of peo-
ple and other obstacles will differ from those shown on the Multi-terrain Monitor
screen. Directly confirm the safety of your surroundings before driving.●
Do not drive while only looking at the scre en. When driving, make sure to directly
confirm the safety of your surroundings, su ch as by visually checking the area and
using the vehicle’s mirrors. ●
In low temperatures, the screen may darken or the images may become faint.
Images of moving objects in particular may distort or disappear from the screen.
Therefore, make sure to drive carefully while directly visually confirming the safety of
your surroundings.
