Low fuel level warning light
The gauge is displayed when the ignition switch is
on and indicates the approximate quantity of fuel
remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ºEº 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
This light has the following two functions:
Parking brake reminder
If this light is on, make sure the parking brake is fully
released. The light should go off.
Low brake fluid level warning
If this light comes on and stays on while you are driving,
slow down and pull off the road. Then stop the vehicle
carefully. Remember that stopping distance and pedal
effort may be increased. There may be a problem
somewhere in the brake system. Check the fluid level
of the see±through reservoir.
To make sure the parking brake has not caused the
warning light to come on, check to see that the parking
brake is fully released.
If the brake fluid level is low ...
At a safe place, test your brakes by starting and
stopping.
If you judge that the brakes still work adequately, drive
cautiously to your nearest dealer or shop for repairs.
 If the brakes are not working, have the vehicle towed
in for repairs. (For towing information, see page 366.)

GAUGES, METERS AND SERVICE REMINDER INDICATORS
66If the brake fluid level is correct ...
Have
the warning system checked by your Lexus dealer.
(b) Driver's Seat Belt Reminder Light
and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light flashes and buzzer sounds if the driver's
seat belt is not fastened. Unless the driver fastens the
belt, the light stays flashing and the buzzer stops after
about 4 to 8 seconds.
(c) Front Passenger's Seat BeltReminder Light
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light flashes if a passenger sits in the front
passenger seat and does not fasten the seat belt.
Unless the front passenger fastens the belt, the light
stays flashing.
If luggage load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built±in sensors in the seat cushion may detect the
pressure, causing the reminder light to come on.
(d) SRS Warning Light
The indicators come on when the ignition key is
turned to the ºACCº or ºONº position. It goes off
after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, inflators, seat belt pretensioners,
warning 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 as described above.
 The light stays on 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 fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.
