Trailer Recommendations - Chevrolet 2007 Colorado Owner's Manual

Maintenance When Trailer Towing
Your vehicle will need service more often
when you're pulling a trailer. See Scheduled
Maintenance on page 442 for more on this.
Things that are especially important in trailer
operation are automatic transmission fluid
(don't overfill), engine oil, axle lubricant, belt,
cooling system and brake system. Each of these
is covered in this manual, and the Index will
help you find them quickly. If you're trailering,
it's a good idea to review these sections before
you start your trip.
Check periodically to see that all hitch nuts
and bolts are tight.

Trailer Wiring Harness
Your vehicle may be equipped with a four-pin
trailer towing harness. This harness has a four-pin
trailer connector that is attached to a bracket on
the hitch platform. The four-wire harness contains
the following trailer circuits:
•
Yellow: Left Stop/Turn Signal
•
Green: Right Stop/Turn Signal
•
Brown: Taillamps/Park lamps
•
White: Ground

Trailer Recommendations

You must subtract your hitch load from the CWR
for your vehicle. Weigh your vehicle with your trailer
attached, so that you won't go over the GVWR or
the GAWR.
You'll get the best performance if you spread
out the weight of your load the right way, and if
you choose the correct hitch and trailer brakes.
For more information, see Towing a Trailer
on page 306 later in this section.
