Sensor detectio n information●
The sensor’s detection areas are limited to the areas around the vehicle’s bumper. ●
Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an obstacle. Pa rticular instances wher e this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor re ceives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there ar e instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

The system will remain off until the height co ntrol “OFF” switch is pushed again, even if
the engine switch is turned off. ●
Even if the system is turned off, the system will interven e 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 ●

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 heig ht 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 abrupt ly 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 un der the vehicle that may come
in contact with the underbody. The vehicle will return to th e 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-informatio n 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.

Driving 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, re sulting 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.

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 co ntrolled effectively by the Ac tive TRAC, which assists the
driver to control the driving power of 4 wheels. ●
Use the 1 range of S or D (vehicles with pa ddle shift switches) for maximum power and
traction when your wheels get stuck or when driving down a steep incline.Center differential lock/unlock switch
