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
transmission 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 perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also pro-
vide better engine braking.
6-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in FIRST gear (using the ERS shift control) can
help to avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified for “police, taxi,
fleet, or frequent trailer towing.”
