ENGINE COOLANT
TEMPERATURE GAUGE
SV13012

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. Thethermostat is designed to control the flow of coolantto keep the temperature of the engine within thespecified operating range.
Do not continue driving with an overheated engine.See ºIf your vehicle overheatsº on page 202.

VOLTMETER
SV13013

1Discharge warning light 2Normal range
The voltmeter tells whether the battery is charged or
discharged. Check it while the engine is running ± the
needle should always indicate as shown above.
If the needle reads below or above the normal range while the
engine is running, it indicates that the charging system needs
immediate repair.
However, it is normal for the needle to drop below the normal
range during engine starting.
MOMENTARY FUEL CONSUMPTIONMETER
SV13018

Vehicles sold in U.S.A.
SV13020

Vehicles sold in Canada

GAUGES, METERS AND SERVICE REMINDER INDICATORS
37
The momentary fuel consumption is calculated and
indicated based on the driving distance and the fuel
consumption with the engine running.
If you are driving at low speeds just before stopping, the
accurate figure may not be shown.
TACHOMETER
SV13016
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine over±revving.
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.
