CAUTION
To avoid serious personal injury, you must do the following.
Always make sure the head, hands and other parts of the
body of all occupants are kept completely inside the vehicle
before you close the power windows. If someone’s neck,
head or hands gets caught in a closing window, it could
result in a serious injury. When anyone closes the power
windows, be sure that they operate the windows safely.
When small children are in the vehicle, never let them use
the power window switches without supervision. Use the
window lock switch to prevent them from making
unexpected use of the switches.

FUEL GAUGE
13L0011
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 ”E” 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 fuelselection.
ENGINE COOLANT
TEMPERATURE GAUGE
13L0022
Normal range
The gauge indicates the engine coolant temperature when the
ignition switch is on. The engine operating temperature will
vary with changes in weather and engine load.
If the needle points to the red zone or higher, stop your vehicle and
allow the engine to cool.
Your vehicle may overheat during severe operating conditions, such
as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high speed driving.

(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 seethrough 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 205.)
CAUTION
It is dangerous to continue driving normally when the brake
fluid level is low.

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 ”ON” or ”START”, 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 Belt Reminder Light
Once the ignition key is turned to ”ON” or ”START”, 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, builtin 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
”ACC” or ”ON” 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.
