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.

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 stop ped, you may hear a sound caused by the
expansion and contraction of the propeller shaft. This does not 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 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 th e warning message turns off, the system is
operating correctly. If the warning message continues to be displayed, have the
vehicle checked at your Lexus dealer as soon as possible.

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.

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.■

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 vehi cles have a signifi-
cantly higher rollov er 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 th e same speeds as ordinary passen-
ger cars any more than low-slung sports cars a re designed to perform
satisfactorily under off-road cond itions. Therefore, sharp turns at
excessive speeds may cause rollover. This vehicle belongs to the utility ve hicle 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.

● A recommended tongue weight varies in accordance with the types of
trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must be
loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongu e weight/Gross trailer weight  100 =
9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitc h when towing, return the front axle
to the same weight as be fore 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 front fender is return ed to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can
be measured with platform scales found at a highway weighing sta-
tion, building supply company, tru cking company, junk yard, etc.
