26
FUEL GAUGE
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.
This fuel gauge has a non-return type needle which remains
at the last indicated position when the ignition switch is turned
off.
If the fuel level approaches “E” or the low fuel level warning light
comes on, fill the fuel tank as soon as possible.
See the inner back cover for fuel capacity and recommended
fuel selection.
ENGINE COOLANT
TEMPERATURE GAUGE
Overheating
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.

Towing a trailer.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
31 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 OK, 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.
NOTICE:
Do not continue driving if the engine drive belt is broken
or loose.
(f) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It is
not designed to indicate low oil level, and the oil level must be
checked using the oil level dipstick.
NOTICE:
Do not drive the vehicle with the warning light on − even
for one block. It may ruin the engine.
(g) Low Engine Oil Level Warning Light
This light warns that the engine oil level is too low. Add oil as
soon as possible. (For instructions, see “Checking the engine
oil level” on page 198.)
NOTICE:
Continued engine operation with low engine oil will
damage the engine.
(h) Malfunction Indicator Lamp
This lamp warns that there is a problem somewhere in your
engine electrical system.
If it comes on while you are driving, have your vehicle
checked / repaired by your Lexus dealer as soon as possible.
(i) Anti-lock Brake System Warning Light
This light warns that there is a problem somewhere in your
anti-lock brake system. When the anti-lock brake system
warning light is on (and the brake system warning light is off),
the brake system operates conventionally but without anti-lock
function.
If the light comes on while you are driving, have your vehicle
checked by your Lexus dealer as soon as possible.
