GAUGES, METERS AND SERVICE REMINDER INDICATORS
48
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.

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.

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.

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 “ON” position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
 You may hear a small sound in the engine compartment
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.
(b) Driver’s Seat Belt Reminder Light and
Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
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
continues flashing and the buzzer stops after about 4 to 8
seconds.
(c) Front Passenger’s Seat Belt ReminderLight
The light acts as a reminder to have the front passenger buckle
up the seat belt.
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 continues flashing.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built−in sensors in the seat cushion may detect the pressure,
causing the reminder light to flash.

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS airbags and seat belt pretensioners are
operating properly.
The SRS warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front passenger occupant cassification system and indicator
light, front passenger seat belt buckle switch, inflators, seat
belt pretensioners, roll sensing of curtain shield airbags off
indicator light, interconnecting wiring and power sources.
If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.
The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
The SRS warning light will come on and front passenger
occupant classification indicator light will indicate “OFF” if
there is a malfunction in the front passenger occupant
classification system.
(e) Engine Oil Replacement Reminder Light (U.S.A. only)
The light acts as a reminder to replace the engine oil.
This light will come on when the ignition key is turned to “ON”
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to “ON” position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to “ON” position. The light will remain on\
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to th e “LOCK” position with the
odometer re ading shown. (For details, see “Odometer and trip
meter” on page 51.)
2. Turn the ignition key to the “ON” position while holding down
the “ODO/TRIP” knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
