GAUGES, METERS AND SERVICE REMINDER INDICATORS

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 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
13L002±2

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 thetemperature of the engine within the specifiedoperating range.
Do not continue driving with an overheatedengine. See ºIf your vehicle overheatsº onpage 356.

TACHOMETER
13L003±1
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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
62This 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.
