ELECTRONICALLY MODULATEDAIR SUSPENSION
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle
height. This adjustment is automatically made in
response to the driving conditions to provide good riding
comfort and stability in all driving conditions.
(a) Vehicle height adjustment
31L343
 1High position 2Normal position
This system maintains a stable vehicle height, regardless
of occupants and luggage weight. Select either of the
following modes using a selector switch. Normal mode:
Suitable for driving on roads with a normal
surface.
High mode: Suitable for driving on rough roads which are
unsurfaced or continually bumpy.
The damping effect is set slightly firmer in the high mode. So
you may feel the vibration of the vehicle compared to in the
normal mode. However, this does not mean a malfunction in
the system. We recommend you use a normal mode in normal
driving.
To change the mode, push the selector switch.
Normal mode:
The vehicle height remains at normal height at all driving
speeds.
High mode:
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalMedium and high speed driving
HighLow speed driving

The indicator light shows the high mode is selected.
CAUTION
For vehicles equipped with the height control switch, be
sure to turn the ignition switch off before jacking. If this
is not done, the vehicle height adjustment function will
operate, which may cause an accident.
Malfunction warning
If the system is malfunctioning, “Height Hi” appears on the
multi−information display, the master warning light comes on
and a warning tone sounds. Although it is no problem to
continue driving, have the s ystem checked by your Lexus
dealer at the first opportunity.

Antilock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an antilock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snowcovered roads.
 Driving with tire chains installed.
 Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The antilock brake system detects vehicle
speeds u sing the speed sensors for respective wheels’
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.“ABS” warning light
31L350
 1 U.S.A. 2Canada
The light comes on when the ignition switch is turned to the
“ON” position. If the anti−lock brake system and the brake
assist system work properly, the light turns off after a few
seconds. Thereafter, if either of the systems malfunctions, the
light comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti −lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti− lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.

IN CASE OF AN EMERGENCY

switch, be sure to turn the ignition switch off
before jacking. If this is not done, the vehicle
height adjustment function will operate, which
may cause an accident.NOTICE
