■In the following cases the 4-Wheel AHC will not operate
●The brake pedal has been depressed for a few seconds or longer while the vehicle is
stopped.
●Vehicle height control has not been frequently used.
●The suspension fluid temperature is lower than -22°F (-30°C).
●There is ice on the suspension.
●Driving on bumpy roads which may caus e the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the center dif-
ferential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid temperature
drops below 5°F (-15°C).
The 4-Wheel 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 sh ort time and the suspension fluid has been
warmed to within normal operating limits , the 4-Wheel AHC will begin operating and
the vehicle height will automatically change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not be able
to be raised, even if the 4-Wheel AHC is operating. In this case, pull the height select
switch to “” then push to “ ” after driving for a short time longer to select the desired
vehicle height.
■Parking and stopping tips
●If you immediately stop the en gine after off-road driving, the vehicle height may gradu-
ally lower. When parking, ma ke 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.
■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.
■4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC , normal mode is automatically selected.
However, the system may not switch to norm al mode depending on the location of the
malfunction.
The warning message is displa yed on the multi-information display, and the 4-Wheel
AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the wa rning message turns off, the system is operat-
ing correctly. If the warning me ssage 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 obstacles.
If you do not do this, body parts may be ca
ught in the vehicle, possibly leading to an
accident.
■Using the high mode
The high 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 acci-
dent.
■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 accident.
■When crossing rivers
Select the high mode and turn off the heig ht 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 the normal 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 vehi cle, 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 auto-
matic leveling function, resulting in an accident.
■When loading cargo on the roof luggage carrier
Do not switch to high mode. Sudden steering could cause the vehicle to lose stability
due to the vehicle’s higher center of gr avity, possibly leading to an accident.

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.
■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 driveshafts from the po wertrain 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 automatic transmission 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 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 slippery
or bumpy surface.
●Do not push the center differential lock/unlock switch when the vehicle is turning or
when its wheels are spinning freely off the ground.
