Towing Tips
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. For in-
creased engine braking on steep downhill
grades, select the LOW range.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy
loads.
• When using the speed control, if you experi-
ence 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
overheating, take the following actions:
• City Driving
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
• Highway Driving
• Reduce speed.
• Air Conditioning
• Turn off temporarily.
