FUEL GAUGE
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 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

GAUGES, METERS AND SERVICE REMINDER INDICATORS
51
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 ºIf your vehicle overheatsº on page 280.
TACHOMETER

GAUGES, METERS AND SERVICE REMINDER INDICATORS
52The 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

GAUGES, METERS AND SERVICE REMINDER INDICATORS
53
This m
eter displays the odometer and two trip meters. To
change the mode indication, push the ºODO/TRIPº
button. E ach time you push the button, 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, 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.
