NOTICE
■When using the wide view front & side 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 circle, and may collide with the obstacle.

■The Multi-terrain Select can be operated when
●Vehicle speed is less than 7 mph (12 km/h)
●Crawl Control is off
■When using Multi-terrain Select
The following functions cannot be switched on or off.
●VSC
●Active TRAC
●Second start mode
A message will be shown on the multi-information display stating that these func-
tions cannot be switched using the VSC OFF switch or the menu and “ENTER”
switches.
■When selecting a terrain mode
If you are unsure which mode is appropriate, select MOGUL when the four-wheel
drive control switch is in L4 or select MUD & SAND when it is in H4.
■When it is difficult to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed by
LOOSE ROCK, MOGUL and ROCK mode.
Drivability can be improved by selecting a mode 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 amount of tire slippage than
the current mode when the amount of tire slippage is small.
■When the vehicle is stuck

NOTICE
■When using the Multi-terrain Monitor
●Even if an obstacle is no longer visible on the side monitor, do not turn the steer-
ing wheel further in the direction the vehicle is turning until the vehicle has moved
completely past the obstacle. If the steering wheel is turned to full lock, the vehi-
cle will turn in the smallest possible turning circle, and may collide with the obsta-
cle.
●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.

Four-wheel drive system
Use the four-wheel drive control switch and center differential lock/unlock
switch to select the following transfer and center differential modes.
■Four-wheel drive control switch
H4 (high speed position)
Normal driving on all types of
roads.
L4 (low speed position)
Driving requiring maximum
power and traction such as
climbing or descending steep
hills, off-road driving, and hard
pulling in sand or mud, etc.
The low speed four-wheel
drive and VSC OFF indica-
tors will come on.

■Center differential lock/unlock switch
Lock the center differential
when your vehicle’s wheels get
stuck in a ditch or when driving
on a slippery or bumpy surface.
The center differential lock indi-
cator will come on.
Unlock the center differential
after the wheels have been
freed, or after moving to a flat,
non-slippery surface.
To unlock the center differential,
push the switch again.

■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 locking/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 differential 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.

CAUTION
■While driving
Observe the following precautions. Failure to do so may cause an accident result-
ing 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 slip-
pery or bumpy surface.
