Driving
CAUTION
■When using the Multi-terrain Monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries:
●When attempting to use the side cameras while the door mirror is folded in, the base
of the door mirror is displayed on the screen and the area in front of the vehicle can-
not be observed. The image displayed on the screen differs depending on the posi-
tion of the door mirror.
●The field of view of the camera is limited. Do not rely solely upon the Multi-terrain
Monitor.
As with unequipped vehicles, drive carefully while directly confirming the safety of
your surroundings.
Take particular care to avoid parked cars and other obstacles.
●Do not drive the vehicle while only lookin g at the monitor screen under any circum-
stances.
Driving while only viewing the monitor screen may cause a collision or lead to an
accident, as the image displayed on the monitor screen may differ from actual condi-
tions. Make sure to visually check the surrounding areas with and without the mirror
while driving.
●Always check visually and with the mirrors to confirm your intended path is clear.
●The camera uses a special lens. The distances between objects and pedestrians that
appear in the image displayed on the sc reen will differ from the actual distances.
●These are just some of the functions of the Multi-terrain Monitor. The steering wheel
timing and amount the steering wheel should be turned differs depending on the road
condition and road surface. Use the Multi-terrain Monitor with full understanding of
the above conditions.
Always confirm that there is appropriate space before attempting to park the vehicle.
●Do not use the Multi-terrain Monitor in the following cases:
• On icy or slick road surfaces, or in snow
•When using tire chains
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check dire ct visually all around the vehicle before
proceeding.

CAUTION
■Conditions which may affect th
e Multi-terrain Monitor system
●If the tires are changed, the position of the guide lines displayed on the screen may be
incorrect. When changing the tires, consult your Lexus dealer.
●Depending on the circumstances of the ve hicle (number of passengers, amount of
luggage, etc.), the position of the guide lines displayed on the screen may change. Be
sure to check visually behind and all around the vehicle before proceeding.
●Depending on the overall length of the ve hicle (if a frontal protection system is
installed or the bumper has been replaced, etc.), the position of the distance guide-
lines displayed on the front monitor may chan ge. Be sure to check visually behind and
all around the vehicle before proceeding.
●When washing the vehicle, do not apply intensive bursts of water to the camera or
camera area. Doing so may result in the camera malfunctioning.
NOTICE
■When using the Multi-terrain Monitor
●Even if an obstacle is no longer visible on the side monitor, do not turn the steering
wheel further in the direction the vehicle is turning until the vehicle has moved com-
pletely past the obstacle. If the steering wheel is turned to full lock, the vehicle will turn
in the smallest possible turning circ le, and may collide with the obstacle.
●It may be difficult to judge distance with the image from the front camera due to the
characteristics of the lens. Drive carefully while checking the actual distance to the
obstacles displayed on the screen. Also, gi ve your full attention to sudden bumps in
the road.
