FUEL GAUGE

Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ªEº or the low fuel level warning light\
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible.See the inner back cover for fuel capacity and recommended
fuel selection.

(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the ªONº position.
 When the parking brake is applied...
This light comes on for a few seconds when the ignition key is
in the ªONº position even after the parking brake is released.
 When the brake fluid level is low...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
When the hydraulic brake booster fails...
If the hydraulic booster causes a problem resulting in poor
braking performance, the warning light comes on and buzzer
sounds continuously.
Have your vehicle checked at your Lexus dealer in the
following cases:
 The light does not come on even if the parking brake is
applied when the ignition key is in the ªONº position.
 The light does not come on even if the ignition key is turned
on with the parking brake released.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If any of the following conditions occurs, immediately
stop your vehicle at a safe place and contact your Lexus
dealer.
 The light does not turn off even after the parking
brake is released while the engine is running.
 The warning buzzer comes on together with the
warning light.
In either case, this can indicate that the brakes may not
work properly and your stopping distance will become
longer. Depress the brake pedal firmly and bring the
vehicle to an immediate stop.
 The brake system warning light remains on together
with the ªABSº warning light.
In this case, not only the anti±lock brake system will fail,
but also the vehicle will become extremely unstable
during braking.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
65
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.

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the ªONº position. It goes off after about 6 seconds. This
means the SRS airbags and front seat belt pretensioners
are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver's seat position sensor, driver's seat belt buckle switch,

indicator light, ªAIRBAG OFFº indicator light, front passenger's
seat belt buckle switch, front seat belt pretensioner
assemblies, inflators, warning light, ªRSCA OFFº indicator
light, interconnecting wiring and power sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts 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 ªONº position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags and/or front passenger occupant
classification system, ªAIRBAG ONº indicator light and
ªAIRBAG OFFº indicator light fail. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.
(e) Malfunction Indicator Lamp

ªONº position and goes off after the engine starts. This
means that the warn ing light system is operating properly.
If the lamp remains on, or the lamp comes on while driving,
first check the followings.
 Empty fuel tank
If the fuel tank is empty, refuel immediately.
 Loose fuel tank cap
If the fuel tank cap is loose, securely tighten it.
These cases are temporary malfunctions. The malfunction
indicator lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your
Lexus dealer as soon as possible.
If the fuel tank is not empty or the fuel tank cap is not
loose...
 There is a problem somewhere in the engine, emission
control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
Contact your Lexus dealer as soon as possible to service the
vehicle.
If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
67
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

operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces.

vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti±lock 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 a 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.
