Any 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 ªONº position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
 You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Driver's Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to buckle up the driver's
seat belt.
Once the ignition key is turned to ªONº or ªSTARTº, the
reminder light flashes and buzzer sounds if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
continues flashing and the buzzer stops after about 4 to 8
seconds.
(c) Front Passenger's Seat Belt Reminder Light
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the ignition key is turned to ªONº or ªSTARTº, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt.
If luggage or other load is placed on the front passenger seat,
depending on its weight, the reminder light may flash.

At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to ªACCº or ªLOCKº position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle's emission control system and
OBD (On±Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see ªEmissions inspection and maintenance (I/M)
programsº on page 532.
(f) ªABSº Warning Light
The light comes on when the ignition key is turned to the ªONº
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 ªABSº warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.

Anti±lock brake system
 Brake assist system
 Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill±start assist control
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system does not
operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces.

following.
Vehicle stability control system
 Active traction control system
 Downhill assist control system

seconds after the ignition key is turned to the ªONº position.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
If the light comes on while driving, the above mentioned
systems do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
In the following cases, contact your Lexus dealer:
 The warning light does not come on after the ignition key is
turned to ªONº.
 The warning light remains on after the ignition key is turned
to ªONº.

Lexus dealer as soon as possible and have it checked.

This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.

3. After adjusting, be sure to tighten the cross rails by
turning knobs clockwise.
CAUTION
Make sure the cross rails are fixed securely by pushing
forward and rearward them. Failure to do so may cause
an unexpected accident or severe injury in the event of
emergency braking or a collision.
Follow the manufacturer's instructions and precautions when
installing the attachments or their equivalent.
CAUTION
When you load cargo on the roof luggage carrier,
observe the following:
 Place the cargo so that its weight is distributed
evenly between the front and rear axles.
 If loading long or wide cargo, never exceed the
vehicle overall length or width. (See ªSpecificationsº
on page 627 for information on your vehicle overall
length and width.)
 Before driving, make sure the cargo is securely
fastened on the roof luggage carrier.
 Loading cargo on the roof luggage carrier will make
the center of the vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss
of control or vehicle rollover due to failure to operate
this vehicle correctly.
 If driving for a long distance, on rough roads, or at
high speeds, stop the vehicle now and then during
the trip to make sure the cargo remains in its place.
 Do not exceed 58 kg (130 lb.) cargo weight on the roof
luggage carrier.
NOTICE
When loading the luggages, be careful not to scratch
the surface of the moon roof.
