Towing Tips
Before setting out on a trip, practice turning,
stopping and backing the trailer in an area
away from heavy traffic.
Manual Transmission – If Equipped
If using a manual transmission vehicle for trailer
towing, all starts must be in first gear to avoid
excessive clutch slippage. Additionally, when
starting on a steep grade (greater than 10%) 4
LO should be used to avoid excessive clutch
slippage. The vehicle should be returned to
either 2WD or 4 AUTO mode once on level
ground.
Automatic Transmission – If Equipped
The “DRIVE” range can be selected when
towing. However, if frequent shifting occurs
while in this range, select TOW/HAUL mode (if
equipped) or a lower gear range.
NOTE:
Using “TOW/HAUL” mode (3.7L Engine) or
selecting a lower gear range using the Elec-
tronic Range Select (ERS) feature (2.8L Die-
sel Engine) while operating the vehicle un-
der heavy operating conditions will improve
performance and extend transmission life
by reducing excessive shifting and heat
build up. This action will also provide better
engine braking.
The automatic transmission fluid and filter
should be changed if you REGULARLY tow a
trailer for more than 45 minutes of continuous
operation. Refer to “Maintenance Schedule” for
the proper maintenance intervals.
