dealer.
• The vehicle is tilted (there is a heavy
load on the vehicle, tire pressure is low
due to a tire puncture, etc.)
• The vehicle is used on an incline.If this happens due to these causes, it
does not indicate a malfunction.
Drive carefully while visually checking the
vehicle’s surroundings.
 Cannot return to the rear view monitor screen

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 wh ile the door mirror is folded in, the base
of the door mirror is displayed on the scre en 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 looking at the monitor screen under any circum-
stances.
Driving while only viewing the monitor sc reen may cause a collision or lead to an
accident, as the image displayed on the mo nitor 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 scre en 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 sp ace 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 direct visually all around the vehicle before
proceeding.

CAUTION
■Conditions which may affect the Multi-terrain Monitor system
●If the tires are changed, the position of th
e 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 vehicle (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 change. 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, give your full attention to sudden bumps in
the road.

■When the four-wheel drive co
ntrol switch can be operated
●The engine switch is in IGNITION ON mode.
●The shift lever is in the N position.
●The vehicle is stopped completely.
■The low speed four-wheel drive indicator
●The indicator blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator continues to blink when you operate the
four-wheel drive control switch to the H4 or L4 position, stop the vehicle completely,
shift the shift lever securely into N and then operate the switch again.
●If the shift lever is moved before the low sp eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted comp letely. The transfer mode disengages both
the front and rear drive shafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the shift lever is in P. You or someone else
could be seriously injured. You must comple te the shifting of the transfer mode and
confirm that the indicator has turned off (H4) or turned on (L4).
●If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.
■When the transfer mode is switched to L4
Vehicles without Multi-terrain Select:
VSC is automatically turned off. (The VSC OFF indicator will come on.)
Vehicles with Multi-terrain Select:
VSC and TRAC/Active TRAC are automatically turned off. (The VSC OFF indicator will
come on and the “TRAC OFF” will be sh own on the multi-information display.)
■When the center differential lock/unlock switch can be operated
The engine switch is in IGNITION ON mode.
■The center differential lock indicator
●The indicator blinks while locking/unlocking the center differential.
●If the center differential lock indicator bl inks and the buzzer sounds when the center
differential is locked, stop the slipping or spinning and push the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.
■Locking/unlocking the center differential
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator does not turn off when unlocking the center differential, drive straight ahead
while accelerating or decelerating, or drive in reverse.
●Avoid turning suddenly while the center differential is locked. If you do turn suddenly,
the difference in turning speeds between the front and rear wheels may have a similar
effect to braking, thus making driving difficult.

■While driving
Observe the following precautions. Failure to do so may cause an accident resulting in
death or serious injury.
●Never move the four-wheel drive control switch if the wheels have lost traction.
●Do not operate the center differential lock/unlock when the vehicle is turning or
when its wheels are spinning freely off the ground.
NOTICE
■To prevent damage to the center differential
●For normal driving on dry and hard surface roads, unlock the center differential.
●Unlock the center differential after the wheels are out of the ditch or off the slippery
or bumpy surface.
