414 STARTING AND OPERATING
Towing Tips
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.
If using a manual transmission vehicle for trailer towing, all
starts must be in first gear to avoid excessive clutch slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur while
in DRIVE, you can use the AutoStick shift control to manu-
ally select a lower gear.
NOTE:
Using a lower gear while operating the vehicle under heavy
loading conditions, will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup. This action will also provide better engine braking.
AutoStick — If Equipped
• When using the AutoStick shift control, select the highest
gear that allows for adequate performance and avoids
frequent downshifts. For example, choose "5" if the
desired speed can be maintained. Choose "4" or "3" 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 of time, shift the transmis-
sion into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
