Sensor detection information ●
The sensor’s detection areas are limited to the areas around the vehicle’s front
corner and rear bumpers. ●
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
• There is dirt, snow or ice on the sens or. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the 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 sensor s 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.
• Towing hook is installed.
• The bumper or sensor receives a strong impact.

• 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 are instances in which, because of their
shape, signs and other objects may be ju dged by the sensor to be closer than
they are.

LX570_OM_OM60L96U_(U) ■
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.

3282-4. Using other driving systems
LX570_OM_OM60L96U_(U) ■
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.
