GAUGES, METERS, AND SERVICE REMINDER INDICATORS S Towing a trailer. S Lugging the engine by driving slowly in a high gear NOTICE S 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. S Do not continue driving with an overheated engine. See "If your vehicle overheats" on page 165. TACHOMETER The tachometer indicates engine speed in thousands of rpm (revolutions per minute). Use it while driving to select correct shift points and 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. 27

GAUGES, METERS, AND SERVICE REMINDER INDICATORS
27
S
Towing a trailer.
S
Lugging the engine by driving slowly in a high gear
NOTICE
S
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.
S
Do not continue driving with an overheated
engine.
See “If your vehicle overheats” on page
165.
TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute).
Use it while driving to
select correct shift points and 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.
