FUEL GAUGE

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 ªEº or the low fuel level warning
light comes on, fill the fuel tank as soon as possible.
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.
Set the inner back cover for fuel capacity and recommended
fuel selection.
ENGINE COOLANT
TEMPERATURE GAUGE

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 ªIf your vehicle overheatsº on page 163.
TACHOMETER
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.
