If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for severe usage (police, fleet,
taxi, or frequent trailer towing). Refer to the #Maintenance
Schedule# for the proper maintenance intervals.
AutoStick®
When using the AutoStick® shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose #4# if
the desired speed can be maintained. Choose #3# or #2# if
needed to maintain the desired speed.
To prevent excess heat generation, avoid continuous driving
at high RPM. Reduce vehicle speed as necessary to avoid
extended driving at high RPM. Return to a higher gear or
vehicle speed when grade and road conditions allow.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, shift the transmission
into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
