Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, select
TOW/HAUL mode (if equipped), or a lower gear range
(using the Electronic Range Select [ERS] shift control).
NOTE: Using the TOW/HAUL mode (if equipped) or
selecting a lower gear range (using the ERS shift control)
while operating the vehicle under heavy loading condi-
tions, will improve performance and extend transmission
life by reducing excessive shifting and heat buildup. This
action will also provide better engine braking.
If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the transmis-
sion fluid and filter(s) as specified for “police, taxi, fleet,
or frequent trailer towing.” Refer to the “Maintenance
Schedule” 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.
