If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a checkup as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its threeway catalytic
converter system best.
 To ensure that the threeway catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
“Owner’s Manual Supplement/Scheduled
Maintenance”.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains
carbon monoxide, which is a colorless and odorless
gas. It can cause unconsciousness or even death.
 Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
 Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
 Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
 Keep the back door closed while driving. An open or
unsealed back door may cause exhaust gases to be
drawn into the vehicle.

(f) Parking and stopping tips
If you immediately stop the engine to park the vehicle after
off−road driving, the vehicle height is lowered slightly as the
vehicle becomes cool. When parking, make sure there is
nothing that will be in contact with the underbody of the vehicle.
When you start the engine, the vehicle returns to the previous
height.
If you park the vehicle for a long time, the vehicle height may
be gradually lowered. When parking for a long time, make sure
there is nothing that will be in contact with the underbody of the
vehicle. When you start the engine, the vehicle returns to the
previous height.
If you stop the engine, the vehicle height may change in
accordance with the change in the temperature. When you
start the engine, the vehicle returns to the previous height.
(g) Rear height control failure warning
If there is a problem somewhere in the rear height control air
suspension, the “N” mode is automatically selected. If this
occurs, the height control “OFF” indicator light blinks and the
vehicle height control cannot be activated until the malfunction
is corrected. If this is the case, bring your vehicle to your Lexus
dealer as soon as possible and have it checked.
ELECTRONIC MODULATED SUSPENSION
This electronic modulated suspension adjusts the
damping effect on the shock absorbers with the control
switch. Select one of the 4 modes which is suited to the
driving conditions with the control switch to provide good
riding comfort and stability.
1For driving on a bumpy road
2For ordinary driving such as in the city traffic
3For moderate high speed driving
4For sporty type driving such as on winding mountain
roads and high speed driving

Slip indicator light
Leave the system on during the ordinary driving so that it
can operate when needed.
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the active traction control
system is in the self−check mode, but does not indicate a
malfunction.
When the active traction control system is operating, the
following conditions occur:
 The system controls the spinning of the 4 wheels. At this
time, the slip indicator light blinks.
 You may feel vibration or noise in your vehicle, caused by
operation of the brakes. This indicates the system is
functioning properly. The slip indicator light comes on for a few seconds when the
ignition key is turned to “ON”. If the indicator light does not
come on when the ignition is turned on, contact your Lexus
dealer.
The brake actuator temperature increase during continuous
operation of the following systems.

Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill −start assist control
If the brake actuator temperature becomes too high while any
of the systems is operating, a buzzer will start to sound
intermittently to indicate that the active traction control system
can no longer operate. In this case, immediately stop your
vehicle at a safe place.
If the system continues to operate, the buzzer sound changes
from intermittent to continuous. (The continuous buzzer
sounds for about 3 seconds.) At the time, the slip indicator light
will come on and the active traction control system temporarily
stops operating in order to protect the brake actuator.
(Although the active traction control system does not operate,
there is no problem to continue your driving.) The system will
be automatically restored after a short time and the slip
indicator light goes out.

can no longer operate. In this case, stop your vehicle
immediately at a safe place.
If the system continues to operate, the buzzer sound changes
from intermittent to continuous. (The continuous buzzer
sounds for about 3 seconds.) At this time, the slip indicator light
will come on and the downhill assist control system stops
operating temporarily in order to protect the brake actuator.
(Although the downhill assist control system does not operate,
it is no problem to continue your driving.) The system will be
automatically restored after a short time and the slip indicator
light goes out.

STARTING AND DRIVING
3942 sets of ID codes can be registered. The code of the tires
originally
installed on the vehicle is registered on the switch at
“MAIN”. Have a new tires set with new air pressure sensors
registered at “2nd” by Lexus dealer.
ID codes should be registered by Lexus dealer. Once
registered, change the setting position each time you purchase
tires and wheels. Re −registration is not required.
When purchasing new tires, consult your Lexus dealer.
CAUTION
When the tires whose ID code is registered at “MAIN”
are used, the system does not work properly with the
selector switch set at “2nd”. If the tires whose ID code
is registered at “2nd” are stored nearby, the system will
detect their tire pressure (and vice versa).
BRAKE PAD WEAR LIMIT INDICATORS
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have the
brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.
