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 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.■

Turn off the height control, otherwise the vehicle height may change due to the
automatic leveling function, resulting in an accident.■

LX570_OM_OM60L96U_(U) CAUTION■
Replacing a flat tire ●
Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from under
the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling
the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or other
body parts while changing a ti re, etc. may result in burns.
• Turn off the vehicle height control.
The vehicle height may change due to the automatic leveli ng function and
you may catch part of your body in th e vehicle, resulting in an accident.
(  P. 320)●
Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading
to bolt or disc wheel damage. In addition, the oil or grease can cause the
wheel nuts to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 97 ft
• lbf (131 N
• m,
13.4 kgf
• m) as soon as possible after changing wheels.
• When installing a tire, only use whee l nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt
holes of the wheel, have the vehicle inspected by your Lexus dealer.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel
while the vehicle is moving.
