could af fect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance problems resulting from the modification may not
be covered under warranty.
If you install any Genuine Accessories such as a bull−bar,
winch, etc., consult your Lexus dealer.
Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference− Causing
Equipment Standard.
Installation of a mobile twoway radio system
As the installation of a mobile two −way radio system in your
vehicle could affect electronic systems such as the multiport
fuel injection system/sequential multiport fuel injection system,
cruise control system, anti −lock brake system, active traction
control system, vehicle stability control system, active height
control system, adaptive variable suspension system, SRS
airbag system and seat belt pretensioner system, be sure to
check with your Lexus dealer for precautionary measures or
special instructions regarding installation.
Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident. Check
the tire inflation pressure periodically and be sure to
keep the load limits given in this Owner’s Manual. For
details about tire inflation pressure and load limits, see
pages 424 and 328.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your
Lexus contain explosive chemicals. If the vehicle is scrapped
with the airbags and seat belt pretensioners left as they are,
this may cause an accident such as a fire. Be sure to have the
systems of the SRS airbag and seat belt pretensioner removed
and disposed of by a qualified service shop or by your Lexus
dealer before you scrap your vehicle.

(g) “ABS” Warning Light
The light comes on when the ignition key 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 active 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.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the components monitored
by the warning light system. Contact your Lexus dealer
as soon as possible to service the vehicle.
 The light does not come on when the ignition key is turned
to the “ON” position or remains on.
 The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.CAUTION
If the “ABS” warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the antilock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Either of the following conditions may occur, but do not
indicate the malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.
(h) Open Door Warning Light
This light remains on until all the side doors and back door are
completely closed.

(l) Vehicle Stability Control System andActive Traction Control System Warning
Light
This light warns that there is a problem somewhere in the
vehicle stability control system and active traction control
system.
If the “VSC/TRAC” warning light and “VSC OFF” indicator light
come on, have your vehicle checked by Lexus dealer as soon
as possible. However, it is no problem that the “VSC/TRAC”
warning light comes on when the brake actuator temperature
becomes high. (For details, see “Active traction control
system” on page 288.)
The lights will stay on with the ignition key turned to “ON”, and
will go off after about a few seconds.
The lights may stay on for 60 seconds after the ignition key is
turned to the “ON” position. It is normal if they go out after a
while.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
When the “VSC/TRAC” warning light and “VSC OFF” indicator
light come on, the vehicle stability control system and/or active
traction control system do not operate, but there is no problem
to continue your driving.
(m) Variable Gear Ratio Steering System Warning Light
This light warns that there is a problem somewhere in the
variable gear ratio steering system.
The light will come on when the ignition key is turned to “ON”
and will go off after a few seconds.
If the light comes on while driving, the system is not working.
Although conventional steering operates when maneuvered,
a larger degree of wheel maneuvering (than at the time when
the system is functioning properly) is needed when driving at
low speed. At this time, the center position of the steering
wheel could be changed. Although it is no problem to continue
driving, have your vehicle repaired at your Lexus dealer.
In the following cases, contact your Lexus dealer:
 The warning light does not come on after the ignition key is
turned to “ON”.
 The warning light remains on after the ignition key is turned
to “ON”.
 The warning light comes on while driving.
The light will flash if you disconnect and reconnect the battery
terminal. This is because the system is reset temporarily.
However, it is no problem to drive. To turn off the light, drive for
a short while. The system will be set automatically and return
to normal.

STARTING AND DRIVING
267
NOTICE
As soon as the center differential lock switch is turned
on, the “VSC OFF” indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
off.
“H” (high speed position, center differential unlocked):
Lever at “H”, center differential lock button left out
Use this for normal driving on all types of roads, from dry
hard−surfaced roads to wet, icy or snow −covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
“H” (high speed position, center differential locked):
Lever at “H”, center differential lock button pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center dif ferential unlock
mode.
“N” (neutral position): Lever at “N”
No power is delivered to the wheels. The vehicle must be
stopped. “L” (low speed position, center differential unlocked):
Lever at “L”, center differential lock button left out
Use this for maximum power and traction. Use this for climbing
or descending steep hills, off
−road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that occurs when the wheels
are negotiating a sharp corner is further reduced than in the “L”
(low position, center differential locked) mode.
“L” (low speed position, center differential locked): Lever
at “L”, center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in situations the vehicle cannot negotiate even in the “L”
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep off −road inclines will
help contribute to increased vehicle stability.
The indicator light tells when the differential lock is engaged.
Note that the differential is not still locked as long as the
indicator light remains off.
When the operation is not completed, the indicator blinks. If
the indicator light does not go off when you push out the center
differential lock switch, drive straight ahead while accelerating
or decelerating, or drive in reverse.
The center differential lock system operation is not completed
within 5 seconds while the cruise control system is set, cancel
the cruise control system. To cancel the cruise control system,
see “Cruise control” on page 275.
