GAUGES, METERS AND SERVICE REMINDER INDICATORS
27
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 ªIf your vehicle overheatsº 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.
