RANSMISSION

To reduce the potential for engine and 

transmission overheating in high ambient 

temperature conditions, take the following 

actions:

City Driving — When stopped, shift the trans

-

mission into NEUTRAL (N) and increase 

engine idle speed.

Highway Driving — Reduce your speed.

Up Steep Hills — Select a lower transmission 

gear.

Air Conditioning — Turn it off temporarily.

NOTE:

If the coolant temperature is too high, the A/C 

will automatically turn off.

Do Not Operate The Engine With Low Oil 

Pressure

If the Low Oil Pressure warning light turns on 

while driving, stop the vehicle and shut down 

the engine as soon as possible. A chime will 

sound when the light turns on.

NOTE:

Do not operate the vehicle until the cause is 

corrected. This light does not show how much 

oil is in the engine. The engine oil level must be 

checked under the hood.

Do Not Operate The Engine With Failed 

Parts

All engine failures give some warning before the 

parts fail. Be on the alert for changes in 

performance, sounds, and visual evidence that 

the engine requires service. Some important 

clues are:

Engine misfiring or vibrating severely

Sudden loss of power

Unusual engine noises

Fuel, oil or coolant leaks

Sudden change, outside the normal oper

-

ating range, in the engine operating tempera

-

ture

Excessive smoke

Oil pressure drop

CAUTION!

If oil pressure falls to less than normal 

readings, shut the engine off immediately. 

Failure to do so could result in immediate and 

severe engine damage.
