Driving

WARNING

■

Using H2 mode

H2 mode should only be used when driv-

ing on rough roads, for example when

driving off-road. Because the vehicle’s

center of gravity will become higher

when in the mode, the vehicle may

become unstable when turning abruptly,

resulting in an accident.

■

When jacking up the vehicle or

installing tire chains

Turn off the height control and stop the

engine, otherwise the vehicle height may

change due to the automatic leveling

function and you may catch part of your

body in the vehicle, resulting in an acci-

dent.

■

When crossing rivers

Select H2 mode and turn off the height

control. Drive at 18 mph (30 km/h) or

lower. Otherwise the vehicle height may

change due to the automatic leveling

function, resulting in an accident.

■

If your vehicle must be towed

Put the vehicle height in N mode and

turn off the height control, otherwise the

vehicle height may change due to the

automatic leveling function and you may

catch part of your body in the vehicle,

resulting in an accident.

■

If your vehicle becomes stuck in a

ditch

Turn off the height control, otherwise the

vehicle height may change due to the

automatic leveling function, resulting in

an accident.

NOTICE

■

When parking in areas with limited

overhead height

After leaving the vehicle or unloading the

luggage, the vehicle height may be

slightly higher than normal. Take care

when overhead height is limited.

■

To avoid damage to the vehicle

●

N mode will be switched to automati-

cally even if the vehicle is started off in

L mode. Take care when overhead

height is limited.

●

Do not select L mode when driving on

bumpy roads, as the underbody of the

vehicle may contact the road surface.

●

When traveling on bumpy roads or

through water, or when towing, turn off

easy access mode.

■

Avoid rapid changes to the vehicle

height

As the pump may overheat. Leave a few

seconds between selections when

changing the vehicle height mode.

Advice for driving on slippery roads

●

If you shift the four-wheel drive control

switch to L4 and the shift lever to the 2

range of M while driving in steep off-road

areas, the output of the brake can be

controlled effectively by the Active

TRAC, which assists the driver to control

the driving power of 4 wheels.

●

Use the 1 range of M for maximum power

and traction when your wheels get stuck

or when driving down a steep incline.

■

The center differential lock indicator

The indicator blinks while locking/unlock-

ing the center differential.

■

The center differential lock switch can

be operated when

●

The engine switch is in ON.

●

The vehicle speed is less than 62 mph

(100 km/h).

■

Locking/unlocking the center differen-

tial

●

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 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.

●

If the center differential lock/unlock is not

completed within 5 seconds while the

cruise control system is on, cancel the

cruise control system.

■

If the low speed four-wheel drive indica-

tor light or the center differential lock

indicator blinks

●

If the low speed four-wheel drive indica-

tor light continues to blink when using the

four-wheel drive control switch, stop the

vehicle completely, move the shift lever

to 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 com-
plete the shifting of the transfer mode.
To complete the shifting, stop the vehicle
completely, 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
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
center differential lock may not be opera-
ble. 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.

356

4-5. Using the driving support systems

WARNING

■

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 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.

NOTICE

■

To prevent damage to the center dif-

ferential

●

For normal driving on dry and hard

surface roads, unlock the center differ-

ential.

●

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 switch when the vehicle is turning

or when its wheels are spinning freely

off the ground.

Crawl Control (with Turn
Assist function)

Allows travel on extremely rough
off-road surfaces at a fixed low
speed without pressing the accel-
erator or brake pedal. Minimizes
loss of traction or vehicle slip when
driving on slippery road surfaces,
allowing for stable driving.

WARNING

■

When using Crawl Control (with Turn

Assist function)

Do not rely solely on the Crawl Control

(with Turn Assist function). This function

does not extend the vehicle’s perfor-

mance limitations. Always thoroughly

check the road conditions, and drive

safely.

■

These conditions may cause the sys-

tem not to operate properly

When driving on the following surfaces,

the system may not be able to maintain a

fixed low speed, which may result in an

accident:

●

Extremely steep inclines.

●

Extremely uneven surfaces.

●

Snow-covered roads, or other slippery

surfaces.

Multi-terrain Select

Multi-terrain Select is a system that
improves drivability in off-road situ-
ations.

Select a mode that most closely
matches the type of terrain on which
you are driving from several modes.
Brake control, drive force control
and suspension control can be opti-
mized in accordance with the
selected mode.

When AUTO mode is selected,
brake control, drive force control
and suspension control are opti-
mized automatically according to
the road conditions.

WARNING

■

When using the Multi-terrain Select

Observe the following precautions to

avoid an accident that could result in

death or serious injuries:

●

Check that the selected mode indica-

tors are illuminated before driving.

Multi-terrain Select will not operate

when the indicators are off.

system to malfunction.

■

Trailer Sway Control precaution

The Trailer Sway Control system is not

able to reduce trailer sway in all situa-

tions. 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 seri-

ous 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.

If you make no extreme correction with
the steering or brakes, your vehicle and
trailer should stabilize. (

WARNING

■

Off-road vehicle precautions

Always observe the following precau-

tions to minimize the risk of death, seri-

ous injury or damage to your vehicle:

●

In a rollover crash, an unbelted person

is significantly 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 maneu-

vers, if at all possible.

Failure to operate this vehicle cor-

rectly may result in loss of control or

vehicle rollover causing death or seri-

ous injury.

●

Loading cargo on the roof luggage

carrier will make the center of the

vehicle gravity higher. Avoid high

speeds, sudden starts, sharp turns,

sudden braking or abrupt maneuvers,

otherwise it may result in loss of con-

trol or vehicle rollover due to failure to

operate this vehicle correctly.

●

Always slow down in gusty crosswinds.

Because of its profile and higher cen-

ter of gravity, your vehicle is more sen-

sitive 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.

■

Off-road driving precautions

Always observe the following precau-

tions to minimize the risk of death, seri-

ous injury or damage to your vehicle:

●

Drive carefully when off the road. Do

not take unnecessary risks by driving

in dangerous 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 effec-

tiveness 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 materials trapped or

adhering to the underbody, a break-

down 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

vehicle’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 trans-

mission will cause deterioration in shift

quality, locking up of your transmission

accompanied by vibration, and ulti-

mately damage.

●

Water can wash the grease from

wheel bearings, causing rusting and

premature failure, 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.

speed suitable to road conditions.



Park the vehicle and move the shift
lever to P without setting the park-
ing brake. The parking brake may
freeze up, preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly lead-
ing to an accident.

When the parking brake is in automatic
mode, release the parking brake after shift-
ing the shift lever to P. (

P.193)



If the vehicle is parked without set-
ting the parking brake, confirm that
the shift lever cannot be moved out
of P

: The shift lever will be locked if it is

attempted to be shifted from P to any
other position without depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a problem
with the shift lock system. Have the vehi-
cle inspected by your Lexus dealer
immediately.
