Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a 25.4 mm (one inch) shank diameter. The bumper has a 2,270
kg (5,000 lb.) trailer weight and 227 kg (500 lb.) tongue weight capacity.
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:
• 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.
• If your vehicle is equipped with a 4–speed automatic
transmission: To eliminate excessive transmission shifting, use a
lower gear. This will also assist in transmission cooling. (For additional
information, refer to the Understanding the positions of the 4–speed
automatic transmission section in this chapter.
• If your vehicle is equipped with a 5–speed automatic
transmission: To eliminate excessive transmission shifting, activate
the Tow/Haul feature. This will also assist in transmission cooling. (For
additional information, refer to the Understanding the positions of
the 5–speed automatic transmission section in this chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide 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.
• The trailer tongue weight should be 10–15% of the loaded trailer
weight.
• After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
