Differences between the rear view or wide rear view and actual roads

The guide lines on the screen are intended for flat surfaces (such as the road).
Be aware of the following points when three-dimensional objects with protru-
sions (obstacles such as the cargo bed of a truck) are nearby.

●

Estimated course lines
Guide lines are displayed in reference to a level road surface and cannot
be used to determine the location of three-dimensional objects. Confirm
the safety of your surroundings directly. Even if it seems that the cargo bed
of a truck is outside the estimated course lines and a collision will not occur
according to the screen, it may actually be in the vehicle course, resulting in
a collision.

Distance guide lines
Guide lines are displayed in reference to the road surface and cannot be
used to determine the distance of three-dimensional objects from the vehi-
cle. Confirm the safety of your surroundings directly. On the screen, it
appears that a truck is parking at point

according to the distance guide

lines. However, in reality if you back up to point

, you will hit the truck.

Under vehicle terrain view
The tire position indicator lines and vehicle position indicator lines may dif-
fer from actual vehicle positions depending on the number of passengers,
weight of the load, road grade, road surface conditions, brightness of the
surrounding environment, etc. Always drive the vehicle while directly con-
firming the safety of your surroundings.

■

Automatic leveling function

Regardless of the number of occupants and the luggage load, vehicle height in any mode

is always adjusted to a fixed height by the automatic leveling function.

■

The rear height control air suspension will not operate in the following cases:

●

The underbody of the vehicle is touching the surface of the road.

●

The area around the suspension is covered with ice.

■

Even if you hear an operating noise

This does not indicate a problem in the rear height control air suspension.

■

Parking and stopping tips

●

If you immediately stop the engine after off-road driving, or park the vehicle for a long

time, the vehicle height may gradually lower. When parking, make sure there is nothing

under the vehicle that may come in contact with the underbody. 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.

■

When lowering the vehicle

In order to prevent the vehicle height from rising as occupants leave the vehicle, lowering

control will occur for a short while after the engine has been stopped.

■

WARNING

■

The rear height control air suspension must be turned off

Be sure to observe the following precautions. Otherwise, the automatic leveling func-

tion may cause vehicle height to change, and you may catch part of your body in the

vehicle, resulting in an accident:

●

When jacking up the vehicle, installing tire chains or tying the vehicle with chains/

wires for transportation via flatbed truck, turn off the rear height control air suspen-

sion and stop the engine.

●

When the vehicle must be towed or disconnecting a trailer, put the vehicle height in N

mode and turn off the rear height control air suspension.

●

When the vehicle is stuck, turn off the rear height control air suspension.

■

Selecting the correct height mode

●

HI mode should only be used when driving 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.

●

Do not select HI mode when loading cargo on the roof luggage carrier.

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.

●

Before lowering vehicle height, check that there is no one under the vehicle.

NOTICE

■

Be careful in any place where overhead space is limited

The vehicle height will rise when a higher mode is selected or cargo is unloaded. This

may cause damage to the vehicle.

■

Do not select LO mode when driving on bumpy roads

If the underbody of the vehicle touches a rugged road surface, the vehicle may be

damaged.

■

Changing vehicle height

Do not change vehicle height frequently.

The compressor may overheat and stop operation.

■

When on the extremely uneven roads with rocks

Sometimes the vehicle height is not adjusted because it is judged as uneven road driv-

ing.

When the four-wheel drive control switch can be operated

●

The engine 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

●

The indicator blinks while switching between H4 and L4.

●

If the low speed four-wheel drive indicator 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 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 and

confirm that the indicator 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 transfer mode is switched to L4

VSC is automatically turned off. (The VSC OFF indicator will come on.)

■

When the center differential lock/unlock switch can be operated

The engine switch is in IGNITION ON mode.

■

The center differential lock indicator

●

The indicator blinks while locking/unlocking the center differential.

●

If the center differential lock indicator 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

●

If the operation is not completed, the center differential lock indicator blinks. If the indi-

cator 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 suddenly,

the difference in turning speeds between the front and rear wheels may have a similar

effect to braking, thus making driving difficult.

Observe the following precautions.

Failing to do so may cause death or serious injury.

●

Firmly grip the steering wheel. Steer straight ahead.

Do not try to control trailer sway 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. (
