FUEL GAUGE
13G001a
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 ºEº 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
13G009a

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.

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 ºIf your vehicle overheatsº on page 217.
TACHOMETER
13G006d
The 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.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.

ODOMETER AND TRIP METER
13G004
This meter displays the odometer and two trip meters. To
change the mode indication, push the ºODO/TRIPº
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 ºODO/TRIPº button. To set the A trip meter
to zero, display the A meter reading, then push the
ºRESETº button. The same applies for the B trip meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.
