■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.

■How to use the camera
●The Multi-terrain Monitor system may not operate properly in the following cases.
• If the front or the rear of the vehicle or the outside rear view mirror has been hit,
the camera’s position and mounting angle may have changed.
• As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation.
• When cleaning the camera lens, flush the camera with a large quantity of water
and wipe it with a soft and wet cloth. Strongly rubbing the camera lens may cause
the camera lens to be scratched and unable to transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the vehi-
cle in cold weather, the system may not operate normally.
• 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.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminated areas may appear to flicker.
• The camera can be damaged by flying rocks and other debris.
●Do not expose the camera to strong impact as this could cause a malfunction. If this
happens, have the vehicle inspected by your Lexus dealer as soon as possible.

■When the four-wheel drive control 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 sw
itching 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 speed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. 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 shown 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 wh ile locking/unlocking the center differential.
●If the center differential lock indicator b links 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.

◆Tr a i l e r S w a y C o n t r o l
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine torque when trailer sway is detected.
Trailer Sway Control is part of the VSC sy stem and will not operate if VSC turned off
or experiences a malfunction.
*: The function only works in vehicles with Multi-terrain Select when Multi-terrain
Select is switched on
If the vehicle is in danger of slipping or
rolling backward when starting on an
incline, or if any of the drive wheels
spins, the slip indicator light flashes to
indicate that the TRAC or Active
TRAC/VSC/Trailer Sway Control/hill-
start assist control systems are operat-
ing.

■Sounds and vibrations caused by the ABS/Multi Terrain ABS, brake assist, TRAC/
Active TRAC, VSC/Trailer Sway Control and hill-start assist control systems
●A sound may be heard from the engine compartment when the engine is started or just
after the vehicle begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS/Multi Terrain ABS is activated.

■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load capac-
ity. In addition, make sure that the tires are inflated to the recommended tire inflation
pressure level.
The ABS/Multi Terrain ABS, TRAC/Active
TRAC and VSC/Trailer Sway Control will
not function correctly if different tires are installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modi fying the suspension will affect the driving
assist systems, and may cause the system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the conditions of the vehicle, trailer, road surface,
and driving environment, the Trailer Sway Control system may not be effective. Refer to
your trailer owner’s manual for information on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
●Begin releasing the accelerator pedal immediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.

■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle:
●Drive carefully when off the road. Do not take unnecessary risks by driving in danger-
ous places.
●Do not grip the steering wheel spokes when driving off-road. A bad bump could jerk
the wheel and injure your hands. Keep both hands and especially your thumbs on the
outside of the rim.
●Always check your brakes for effectiveness immediately after driving in sand, mud,
water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these materi-
als trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain , do not drive at excessive speeds, jump,
make sharp turns, strike objects, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the engine or other
components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission
will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately damage.
●Water can wash the grease from wheel bearings, causing rusting and premature fail-
ure, and may also enter the differentials, transmission and transfer case, reducing the
gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when crossing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water.
■Inspection after off-road driving
●Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components.
●Always perform a maintenance inspection afte r each day of off-road driving that has
taken you through rough terrain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Services Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.
