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 “E” or the low fuel level warning light
comes on, fill the fuel tank as soon as possible.
See 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.

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 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.
