P.354).

■

Cold weather operation

●

It may take longer for the vehicle height

to change if the suspension fluid tem-

perature drops below 5°F (-15°C).

●

The AHC does not operate when the

suspension fluid temperature drops

below -22°F (-30°C). In this case, even if

the height select switch is pressed, the

vehicle height will not change. Once the

vehicle has been driven for a short time

and the suspension fluid has been

warmed to within normal operating limits,

the AHC will begin operating and the

vehicle height will automatically change

to the selected mode.

■

Parking and stopping tips

●

If you immediately stop the engine after

off-road driving, the vehicle height may

gradually lower. When parking, make

sure there is nothing under the vehicle

that may come in contact with the under-

body. The vehicle will return to the set

height when the engine is started.

●

The vehicle height may change as the

temperature changes when the engine is

stopped. The vehicle will return to the set

height when the engine is started.

■

Propeller shaft noise

If the vehicle height is adjusted on a slope,

or with the shift lever in a position other than

P or N while the vehicle is stopped, you may

hear a sound caused by the expansion and

contraction of the propeller shaft. This does

not indicate a malfunction.

Stop the engine and start it again. If the

warning message turns off, the system is

operating correctly. If the warning mes-

sage continues to be displayed, have the

vehicle checked at your Lexus dealer as

soon as possible.

WARNING

■

When switching the vehicle height

mode

Before lowering the vehicle height,

check that there are no people under or

around the vehicle, and check for obsta-

cles.
If you do not do this, body parts may be

caught in the vehicle, possibly leading to

an accident.

■

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.
