– Check the trailer tires for proper tire inflation pressures
before trailer usage.
– Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for proper
inspection procedure.
– When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Tips
NOTE: To provide optimum towing performance and to
protect transmission components always select Trailer
Tow mode when towing a trailer.
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. The
transmission controls include an adaptive drive strategy
to avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you can use
the AutoStick® shift control to manually select a lower
gear.
NOTE: Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
