Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
TOW/HAUL mode (if equipped), or a lower gear range,
should be selected.
NOTE: Using the TOW/HAUL mode (if equipped) or
selecting a lower gear range (using the Electronic Range
Select (ERS) feature) while operating the vehicle under
heavy operating conditions, will improve performance
and extend transmission life by reducing excessive shift-
ing and heat buildup. This action will also provide better
engine braking.
The transmission fluid and filter should be changed if
you REGULARLY tow a trailer for more than 45 minutes
of continuous operation. Refer to “Maintenance Sched-
ule” for the proper maintenance intervals.
NOTE: Check the transmission fluid level before towing
(5.7L engine).
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.
