■The center differential lock indicator light
The indicator light blinks
while locking/unlocking the center differential.
■The center differential lock/unlock switch can be operated when
●The engine switch is in IGNITION ON mode.
●The vehicle speed is less than 62 mph (100 km/h).
■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
lights come on.)
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator light does not turn off when unlocking the center diff erential, drive straight ahead
while accelerating or decelera ting, or drive in reverse.
●If the center differential lock/unlock is no t completed within 5 seconds while the cruise
control system is on, cancel the cruise control system.
■If the low speed four-wheel driv e indicator light or the center differential lock indicator
light blinks
●If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, stop the vehicle completely, move the shift lever to N and
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 driveshafts from the po wertrain 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 automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
To complete the shifting, stop the vehicle co mpletely, return the shift lever to N, and
confirm that the shift was completed (the indicator turns on/off).
●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 low speed four-wheel drive indicator light or the center differential lock indicator
light continues to blink even after attempting the above, there may be a malfunction in
the engine, the brake system or the four-wheel drive system. In this case, you may not be
able to shift between H4 and L4, and the cent er differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.

WARNING
■While driving
Never move the four-wheel drive control switch if the wheels have lost traction. Doing
so may cause an accident result ing in death or serious injury.
■When the vehicle is parked
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 driveshafts from the po wertrain 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 automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
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.
●Do not push the center differential lock/unlock switch when the vehicle is turning or
when its wheels are spinning freely off the ground.

■When it is difficult to generate traction
MUD & SAND mode provides the largest amou nt of tire slippage, followed by LOOSE
ROCK, MOGUL, ROCK & DIRT and ROCK mode.
Drivability can be improved by selecting a mo de which provides a smaller amount of tire
slippage than the current mode when the amount of tire slippage is large, or conversely
selecting a mode which provides a larger amou nt of tire slippage than the current mode
when the amount of tire slippage is small.
■When the vehicle is stuck
Switching the transfer and differential
For the operation of the following func tions, refer to the following pages.
●Four-wheel drive system (P. 310)
●Center differential lock ( P. 311)

tor will flash, and Multi-terrain Select will be temporarily inoperable. In this event, stop
the vehicle immediately in a safe place, and allow the brake system to cool down suffi-
ciently. (There is no problem wi th continuing normal driving.)
After a short time, the TRAC OFF indicator will go off, and you will be able to use Multi-
terrain Select.

■Sounds and vibrations caused by the Multi Terrain AB S, brake assist, Active TRAC,
VSC, Trailer Sway Control, hill -start assist control and VGRS
●A sound may be heard from the engine compartment when the engine is started or just
after the vehicle begins to move. This soun d 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 afte r the vehicle comes to a stop.
• The brake pedal may pulsate slightly af ter the Multi Terrain ABS is activated.

Off-road precautions
●Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehi
cles have a significantly higher rollover
rate than other types of vehicles.
●An advantage of the higher ground cl earance is a better view of the road
allowing you to anticipate problems.
●It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.
This vehicle belongs to the utility vehicle class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity to
make it capable of performing in a wi de variety of off-road applications.

WARNING
■Off-road vehicle precautions
Always observe the following precautions to
minimize the risk of death, serious injury
or damage to your vehicle:
●In a rollover crash, an unbelted person is si gnificantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten
their seat belts.
●Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or vehicle rollover
causing death or serious injury.
●Loading cargo on the roof luggage carrier will make the ce nter of the vehicle gravity
higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly.
●Always slow down in gusty crosswinds. Be cause of its profile and higher center of
gravity, your vehicle is more sensitive to side winds than an ordinary passenger car.
Slowing down will allow you to have better control.
●Do not drive horizontally across steep slopes . Driving straight up or straight down is
preferred. Your vehicle (or any similar off- road vehicle) can tip over sideways much
more easily than forward or backward.
