GAUGES, METERS AND SERVICE REMINDER INDICATORS

FUEL GAUGE
13L062d
Low fuel level warning light
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 “E” 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
13L151
 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 “If your vehicle overheats” on page 404.
TACHOMETER
13L144
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.
