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 vehi-
cle 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 cause the suspension to fully elongate. ●
If the steering wheel is abruptly turned more than 3/4 of a revolution with the
center differential lock system activated.■
Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture 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 short time and the suspension
fluid has been warmed to within normal operating limits, the 4-Wheel AHC will
begin operating and the vehicle height wi ll 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 engine after off-road driving, the vehicle height may
gradually lower. When parking, make su re 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 no t indicate a malfunc-
tion. ■
4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC, normal mode is automatically
selected. However, the system may not sw itch to normal mode depending on the
location of the malfunction.
The warning message is displayed on th e multi-information display, and the 4-
Wheel AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If th e warning message turns off, the system is
operating correctly. If the warning messag e continues to be displayed, have the
vehicle checked at your Lexus dealer as soon as possible.

When driving
LX570_OM_OM60L21U_(U) CAUTION■
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 caught in the vehicle, possibly leading to an
accident. ■
Using the high mode
The high mode should only be used wh en 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 turnin g abruptly, result-
ing 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 accident. ■
When crossing rivers
Select the high 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 func-
tion, 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 vehicle, resulting in an accident. ■
If your vehicle beco mes 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. ■
When loading cargo on the roof luggage carrier
Do not switch to high mode. Sudden steeri ng could cause the vehicle to lose stabil-
ity due to the vehicle’s higher center of gravity, possibly leading to an accident.

LX570_OM_OM60L21U_(U) 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 ●
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 drivin g 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.

Off-road precautions Off-road vehicle feature
● Specific design characteristics give it a higher center of gravity than
ordinary passenger cars. This vehicle design feature causes this type of
vehicle to be more likely to rollover . And, utility vehicles have a signifi-
cantly higher rollover rate than other types of vehicles.
● An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at the same speeds as ordinary passen-
ger cars any more than low-slung sp orts cars are designed to perform
satisfactorily under off-road cond itions. Therefore, sharp turns at
excessive speeds may cause rollover. This vehicle belongs to the utility vehicle class, which has higher ground
clearance and narrower tread in relation to the height of its center of grav-
ity to make it capable of performing in a wide variety of off-road applica-
tions.

weight is 9% to 11%. (Tongue we ight/Gross trailer weight  100 =
9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distri buting hitch when towing , return the front axle
to the same weight as before the trailer connection.
If front axle weight cannot be mea sured directly, measure the front
fender height above the front axle before connection. Adjust weight
distributing hitch torque until fr ont fender is returned to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can be
measured with platform scales foun d at a highway weighing station,
