GAUGES, METERS AND SERVICE REMINDER INDICATORS
51


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.
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.

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 thetemperature of the engine within the specifiedoperating range.
Do not continue driving with an overheatedengine. See ºIf your vehicle overheatsº onpage 319.

TACHOMETER
13E003
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.

ºODO/TRIPº knob
This meter displays the odometer and two trip
meters. To change the mode indication, push the
ºODO/TRIPº 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.
