The vehicle is adjusted to a fixed height for
each mode, regardless of the number of
occupants and the luggage load.
■
When the vehicle is stopped during
driving
The activation of the automatic leveling
function may cause the vehicle height to
change. This is not a malfunction.
■
If the vehicle height does not change
If the vehicle is loaded too heavily, or the
undercarriage has come into contact with
the road surface, the vehicle height cannot
be raised/lowered.
In the following situations, the vehicle is
loaded too heavily. Take extra care when
driving in this condition.

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.
■
AHC failure warning
●
If a malfunction occurs in the AHC, N
mode is automatically selected. How-
ever, the system may not switch to N
mode depending on the location of the
malfunction. The warning message is dis-
played on the multi-information display,

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.
