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 Eº 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.It is not a malfunction even if the needle of the fuel gauge
returns to Eº when the ignition switch is turned to the STARTº
position.
See the inner back cover for fuel capacity and recommended
fuel selection.

ENGINE COOLANT
TEMPERATURE GAUGE

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.
Idling for a long period with the air conditioning on in
stop-and-go traffic.

temperature gauge returns to Cº when the ignition switch is
turned to the STARTº.

TACHOMETERThe tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine over-revving.
Driving with the engine running too fast causes excessive
engine wear and poor fuel economy. Remember, in most
cases the slower the engine speed, the greater the fuel
economy.
It is not a malfunction even if the needle of the tachometer
returns to the bottom position when the ignition switch is turned
to the STARTº position.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.

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 ABSº warning light.
In this case, not only the anti-lock brake system will fail,
but also the vehicle will become extremely unstable
during braking.
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 ONº position. It is normal if it turns off
after a while.

warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.

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.

built-in sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.

sensor assemblies, curtain shield airbag sensor assemblies,
driver's seat position sensor, driver's seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,

to service the vehicle.
When the ignition key is turned to the ONº position, the light
does not come on, remains on or flashes.
The light comes on or starts flashing while driving.

a problem.
