FUEL GAUGE
13X500
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 “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
fuel selection.
ENGINE COOLANT
TEMPERATURE GAUGE
13X501
 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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
49
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.
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 338.
ENGINE OIL PRESSURE GAUGE
13X623
 1
Normal driving 2Idling
The engine oil pressure gauge indicates engine oil
pressure when the ignition is on. Check it while driving to
make sure the needle is in the proper range.
If the engine oil pressure should stay below the normal range,
pull off the road to a safe place and stop the engine
immediately. Call a Lexus dealer or qualified repair shop for
assistance.
Engine oil pressure may not build up when the engine oil level
is too low. The engine oil pressure gauge is not designed to
indicate engine oil level, and the engine oil level must be
checked using the level dipstick.

NOTICE
Do not drive the vehicle with the engine oil pressure
below the normal range until the cause is fixed it may
ruin the engine.
VOLTMETER
13X503a
 1 Normal range 2Charging system warning light
The voltmeter tells whether the battery is charged or
discharged. Check it while the engine is running the
needle should always indicate as shown above.
If the needle reads below or above the normal range while the
engine is running, it indicates the charging system needs
immediate repair.
However, it is normal for the needle to drop below the normal
range during engine starting.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
51
TACHOMETER
13X504c
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
13X505
“ODO/TRIP” knob
This meter displays the odometer and two trip meters. To
change the mode indication, push the “ODO/TRIP” knob
briefly. Each time you push the knob, the mode changes
in order from the odometer to trip meter A to trip meter B,
then back to the odometer, etc.
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 set the A trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the “ON” position.
 When the parking brake is applied ...
This light comes on for a few seconds when the ignition key is
in the “ON” position even after the parking brake is released.
 When the brake fluid level is low ...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
When the hydraulic brake booster fails ...
If the hydraulic booster causes a problem resulting in poor
braking performance, the warning light comes on and buzzer
sounds continuously.
Have your vehicle checked at your Lexus dealer in the
following cases:
 The light does not come on even if the parking brake is
applied when the ignition key is in the “ON” position.
 The light does not come on even if the ignition key is turned
on with the parking brake released.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If any of the following conditions occurs, immediately
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 “ABS” warning light.
In this case, not only the antilock brake system will fail,
but also the vehicle will become extremely unstable
during braking.
