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. However, if frequent
shifting occurs while in this range,
select a lower gear range using the
AutoStick® shift control (for
versions/markets, where provided).
NOTE:
Selecting a lower gear range while
operating the vehicle under heavy
operating conditions will improve
performance and extend transmis-
sion life by reducing excessive
shifting and heat buildup. This ac-
tion will also provide better engine
braking.
If you REGULARLY tow a trailer for
more than 45 minutes of continuous
operation, then change the automatic
transmission fluid and filter accord-
ing to the interval specified for “po-
lice, taxi, fleet, or frequent trailer tow-
ing.” Refer to the “Maintenance
Schedule” for the proper maintenance
intervals.
