Driving while you tow
When towing a trailer:
•
Keep your speed no faster than 70 mph (113 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
•
Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•
Consult your local motor vehicle speed regulations for towing a trailer.
•
To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer to
Automatic
transmission operation
in the
Driving
chapter.
•
Anticipate stops and brake gradually.
•
Do not exceed the GCWR rating or transmission damage may occur.
If your vehicle is equipped with AdvanceTrac
威
with RSC, you may
experience AdvanceTrac
威
with RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac
威
stability enhancement system to activate.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your
scheduled maintenance
information
for more information.
Trailer towing tips
•
Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•
Allow more distance for stopping with a trailer attached.
•
If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
