2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
TRAILER TOWING
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing:
•
Stay within your vehicle’s load limits.
•
Thoroughly prepare your vehicle for towing. Refer to
Preparing to
tow
in this chapter.
•
Use extra caution when driving while trailer towing. Refer to
Driving
while you tow
in this chapter.
•
Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the “Service Guide”.
•
Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
•
Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Your vehicle is pre-wired for trailer towing. An electrical connector is
provided under the instrument panel for installing a customer-supplied
electric brake controller. Another electrical connector is provided at the
hitch. This connector provides power to the trailer for taillamps, stop
and turn lamps, back up lamps, battery charge, electric brakes (when a
customer provided controller is installed) and ground. The kit included
with your vehicle provides you with adaptors to attach the brake
controller and convert the hitch connector for Class I trailer usage.
