Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. See
Scheduled
Maintenance on page 445
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
