CAUTION
■Conditions which may affect the Multi-terrain Monitor system
●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. Have the vehicle
inspected by your Lexus dealer.
●As the camera has a water proof constr uction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If the camera lens is extremely dirty, wash with a mild
cleanser and rinse.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
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.
●The displayed image may be darker and mo ving images may be slightly distorted
when the system is cold.
●Situations unsuitable for Multi-terrain Monitor
• On icy or slick road surfaces, or in snow
• When using tire chains
●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 four-wheel drive control switch can be operated
●The “ENGINE START STOP” 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 light
●The indicator light blinks while switching between H4 and L4.
●If the low speed four-wheel drive indicator light 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 dis-
engages 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 complete the shifting of the transfer
mode and confirm that the indicator light 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 center differential lock/unlock switch can be operated
The “ENGINE START STOP” switch is in IGNITION ON mode.
■The center differential lock indicator light
●The indicator light blinks while lockin g/unlocking the center differential.
●If the center differential lock indicator light blinks 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
●When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator light will come on.)
●If the operation is not completed, the center differential lock indicator blinks. If
the indicator light 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 diff erential is locked. If you do turn sud-
denly, the difference in turning speeds between the front and rear wheels may
have a similar effect to braking, thus making driving difficult.

PCS (Pre-Collision System)
: If equipped
When the system detects the possibilit y of a frontal collision, the systems
such as the brakes and seat belts are automatically engaged to lessen
impact and injuries to occupant s as well as vehicle damage.
■Pre-collision seat belts (front seat belts only)
If the system detects that a collisio n is unavoidable, the system will
retract the seat belt be fore the collision occurs. 
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. ( P. 8 8 )
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■ Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in rela tion to how strongly the brake
pedal is depressed.
■ Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light , warning display and buzzer. If
the system determines that a collision is unavoidable, the brakes are
automatically applied to reduce the collision speed. Pre-collision
braking can be disabled using th e pre-collision braking off switch.
