GAUGES, METERS AND SERVICE REMINDER INDICATORS

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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
35 Idling for a long period with the air conditioning on in
stopandgo traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in the engine cooling system as
this may cause the engine to overheat. The thermostat is
designed to control the flow of coolant to keep the
temperature of the engine within the specified operating
range.
Do not continue driving with an overheated engine. See ”If
your vehicle overheats” on page 196.
TACHOMETER
13L0031
The tachometer indicates engine speed in thousands of rpm
(revolutions per minute). Use it while driving to prevent engine
overrevving.
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.
NOTICE
Do not let the indicator needle get into the red zone. This may
cause severe engine damage.

ODOMETER AND TRIP METER
13L0041
This meter displays the odometer and two trip meters. To
change the mode indication, push the ”ODO/TRIP” button.
The odometer records the total distance the vehicle has been
driven. The twin trip meter records two different distances
independently.
For example, you can use one meter to calculate the fuel economy
and the other to measure the distance on each trip.
To change the trip meter indication from one trip to the other,
push the ”ODO/TRIP” button. To set the A trip meter to zero,
display the A meter reading, then push the ”RESET” button.
The same applies for the B trip meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

warning light
(j) Key reminder buzzer Remove key.
(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.
