Extra high mode
If the vehicle becomes stuck or the Craw l Control 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. (20 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 control 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 rema in off until the height contro l OFF switch is pushed again,
even if the “ENGINE START STOP” switch is turned off. ●
Even if the system is turned off, the sy stem automatically modulated if the vehi-
cle speed exceeds 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 condition.
If the vehicle height cannot be raised ev en after unloading the vehicle, pull the
height select switch to “ ” then push to “ ”. If the vehicle height still cannot be
raised, turn the ignition off then on again, then try once more.■
When the vehicle is st opped 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 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 caus e 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.

When driving
LX570_OM_OM60L96U_(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. Beca use the vehicle’s center of gravity will become higher
when in the mode, the vehicle may become unstable when turning 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 func tion 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
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 th e automatic leveling function and you may
catch part of your body in the ve hicle, 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.■
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_OM60L96U_(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 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.

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 “S” or “D” (vehicles with paddle shift switches) 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 “S” or “D” (vehicles with paddle shift switches) of the shift
lever for maximum power and traction wh en your wheels get stuck or when
driving down a steep incline.■
The center differential lock indicator light
The indicator light blinks while lock ing/unlocking the center differential.■
The center differential lock/unlock switch can be operated when ●
The “ENGINE START STOP” switch is in IGNITION ON mode.●
The vehicle speed is less than 60 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 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.

Function limitations
Crawl Control ●
In the following situations, brake control can be used to drive downhill at a con-
stant speed. However, engine control is not available when driving uphill at a
constant speed.
• When switched to second start mode. ●
In the following situation, engine contro l and brake control will stop temporarily.
In this event, the Crawl Control indicator will flash.
• When the vehicle speed exceeds approximately 15 mph (25 km/h).
Turn Assist function
In the following situations, the Turn Assist function will stop temporarily. In this
event, the Turn Assist indicator will flash. ●
When the vehicle speed exceeds approximately 6 mph (10 km/h). ●

If Crawl Control is used continuously for a long time, the buzzer will sound, a
malfunction notification will be displaye d on the multi-information display, the
Crawl Control indicator will go off, and Crawl Control will be temporarily inop-
erable as a result of the brake system overheating. In this event, stop the vehicle
immediately in a safe place, and allow th e brake system to cool down sufficiently
until the “TRAC OFF” on the multi-information display goes off. (In the mean-
time, normal driving is possible.) ●
If Crawl Control is used continuously for a long time, the buzzer will sound, the
system will be temporarily canceled, and a malfunction notification will be dis-
played on the multi-informat ion display as a result of the automatic transmission
system overheating. Stop the vehicle in a safe place until the display goes off.
