426 STARTING AND OPERATING
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
The DRIVE range can be selected when towing. The trans -
mission controls include a drive strategy to avoid frequent
shifting when towing. However, if frequent shifting does
occur while in DRIVE, select TOW/HAUL mode or select a
lower gear range (using the Electronic Range Select (ERS)
shift control).
NOTE:
Using TOW/HAUL mode or selecting a lower gear range
(using the ERS shift control) while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat build up. This action will also provide better engine
braking.
Tow/Haul Mode
To reduce potential for automatic transmission overheating,
activate TOW/HAUL mode when driving in hilly areas, or
select a lower gear range (using the Electronic Range Select
(ERS) shift control) on more severe grades.
Speed Control — If Equipped
• Do not use on 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
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.
