Safety Chains; Trailer Brakes; Trailer Wiring Harness - Cadillac CTS-V 2009 Owner's Manual

Total Weight on the Vehicle's Tires
Be sure the vehicle's tires are inflated to the upper
limit for cold tires. These numbers can be found on
the Certification label. See Loading the Vehicle
on page 4-20. Make sure not to go over the GVW
limit for the vehicle, or the GAWR, including the
weight of the trailer tongue.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why the right hitch is needed.
•
The rear bumper on the vehicle is not intended
for hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
•
Will any holes be made in the body of the vehicle
when the trailer hitch is installed? If so, be sure to
seal the holes when the hitch is removed. If they are
not sealed, deadly carbon monoxide (CO) from the
engine's exhaust can get into the vehicle. See
Engine Exhaust on page 2-50. Sealing the holes will
also prevent dirt and water from entering the vehicle.

Safety Chains

Always attach chains between the vehicle and the
trailer. Cross the safety chains under the tongue of the
trailer to help prevent the tongue from contacting
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer's recommendation for attaching
safety chains and do not attach them to the bumper.
Always leave just enough slack so the rig can turn.
Never allow safety chains to drag on the ground.

Trailer Brakes

Does the trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so
they are installed, adjusted and maintained properly.
Because the vehicle has StabiliTrak
into the vehicle's hydraulic brake system. If you do,
both brake systems will not work well, or at all.

Trailer Wiring Harness

All of the electrical circuits required for the trailer lighting
system can be accessed at the driver's side rear
lamp connector. This connector is located under the
carpet on the rear corner of the trunk compartment.
