turn the system back on.
■Operating conditions
●The engine must be running.
●Vehicle height control must be turned off.
●All side doors and the back door must be closed.
■Switching vehicle height mode while the engine is stopped
●If the engine is stopped while the vehicle height is being lowe red, lowering will continue.
●If any luggage is removed from the vehicle or if any occupants leave the vehicle within
approximately 30 seconds of the engine switch being turned off, the vehicle height may
be lowered by the auto leveling function.
●Operating the height select switch will have no effect while the engine is stopped.
■Automatic change in vehicle height when the four-wheel drive control switch is in the
L4 position
If the vehicle speed exceeds 2 mph (3 km/h) while driving on an uneven road with the
four-wheel drive control switch in the “L4” position, high mode is automatically selected.
(On even roads, the height mode will not change.)
■Automatic change in vehicle height when in the high mode
●If the vehicle speed exceeds 18 mph (30 km/h) with the four-wheel drive control switch
in the “H4” position, normal mode is automatically selected.
●If the vehicle speed exceeds 30 mph (50 km/h) with the four-wheel drive control
switch in the “L4” position, the vehicle heig ht is lowered to 1.0 in. (25 mm) higher than
the normal mode height. If the vehicle speed drops to 13 mph (20 km/h) or less, high
mode is automatically resumed.

■Extra high mode
If the vehicle becomes stuck or the Crawl Co
ntrol system requests the vehicle height be
raised, extra high mode may be automatically selected when the vehicle height is in high
mode with the four-wheel drive control switch in the L4 position.
The vehicle height is raised to 0.8 in. (2 0 mm) higher than the high mode height, or
slightly higher.
●Extra high mode will change back to high mode when:
• The vehicle speed exceeds 6 mph (10 km/h)
• The four-wheel drive contro l switch is shifted to H4.
●If you pull the height select switch to “ ” when in extra high mode, normal mode is
selected.
●Extra high mode cannot be manually selected.
■Turning off the height control
●The system will remain off until the height control “OFF” switch is pushed again, even if
the engine switch is turned off.
●Even if the system is turned off, the system will intervene automatically if the vehicle
speed exceeds the following.
• 18 mph (30 km/h) with high or low mode
• 50 mph (80 km/h) with normal mode
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.
●However the vehicle cannot be raised if the vehicle load exceeds the following limits:
• Up to 4 occupants
* plus approximately 661 lb. (300 kg) in the normal mode
• Up to 4 occupants
* plus approximately 441 lb. (200 kg) in the high mode
*: average weight 150 lb. (68 kg) per person
●If the vehicle height cannot be raised when in the normal mode, and “LO” appears on
the display, the vehicle is loaded too heavily. Take extra care when driving in this condi-
tion.
If the vehicle height cannot be raised even after unloading the vehicle, pull the height
select switch to “ ” then push to “ ”. If the vehicle height stil l cannot be raised, turn the
ignition off then on again, then try once more.
■When the vehicle is stopped during driving
The activation of the automatic leveling func tion 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 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.

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 wh en overhead height is limited.
■To avoid damage to the vehicle
●Normal mode will be switched to automatically even if the vehicle is started off in low
mode. Take care when overhead height is limited.
●Do not select the low mode when driving on bumpy roads, as the underbody of the
vehicle may contact the road surface.
●When traveling on bumpy roads or throug h water, or when towing, turn off easy
access mode.
■Avoid rapid changes to the vehicle height
As the pump may overheat. Leave at a few seconds between selections when changing
the vehicle height mode.

■The center differential lock indicator light
The indicator light blinks
while locking/unlocking the center differential.
■The center differential lock/unlock switch can be operated when
●The engine switch is in IGNITION ON mode.
●The vehicle speed is less than 62 mph (100 km/h).
■Locking/unlocking the center differential
●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 di fferential lock indicator blinks. If the indi-
cator light does not turn off when unlocking the center diff erential, drive straight ahead
while accelerating or decelera ting, or drive in reverse.
●If the center differential lock/unlock is no t completed within 5 seconds while the cruise
control system is on, cancel the cruise control system.
■If the low speed four-wheel driv e indicator light or the center differential lock indicator
light blinks
●If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, stop the vehicle completely, move the shift lever to N and
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 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.
To complete the shifting, stop the vehicle co mpletely, 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
light 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 cent er differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.
