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.

27 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 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.

ODOMETER AND TRIP METER
This meter displays the odometer and two trip meters. To
change the mode indication, push the “ODO / TRIP”
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 “ODO /TRIP” button. To set the A trip meter
to zero, display the A meter reading, then push the
“RESET” button. The same applies for the B trip meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

down and pull off the road. Then stop the vehicle carefully.
Remember that stopping distance and pedal effort may be
increased. There may be a problem somewhere in the brake
system. Check the fluid level of the see−through reservoir.

light to come on, check to see that the parking brake is fully
released.

At a safe place, test your brakes by starting and stopping.
If you judge that the brakes still work adequately, drive
cautiously to your nearest dealer or shop for repairs.
