NOTE: Under certain conditions the engine fan will run
after the engine is turned off. These conditions are under
high load and high temperature conditions.
Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
•
City Driving — When stopped, shift the transmission
into NEUTRAL 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.
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.
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 operating range, in
the engine operating temperature.
•
Excessive smoke.
•
Oil pressure drop.
