If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
• To ensure proper break-in of powertrain components, do not trailer
tow during the first 1,000 miles (1,600 km) of a new vehicle.
• To ensure proper break-in of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph
(113 km/h) with no full throttle starts.
• Consult your local motor vehicle speed regulations for towing a trailer.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
• For additional information, refer to Automatic transmission
operation in the Driving chapter.
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
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• 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.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
• After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• 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. Also, see the information on tow/haul mode operation
under Automatic transmission operation in the Driving chapter.
