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.
