Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See Scheduled Maintenance on page 6-4 or the
Index for more information. Things that are especially
important in trailer operation are automatic transmission
fluid, engine oil, axle lubricant, belts, cooling system and
brake system. It is a good idea to inspect these before
and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The 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
Subtract the hitch loads from the Cargo Weight
Rating (CWR). CWR is the maximum weight of the
load the vehicle can carry. It does not include the
weight of the people inside, but you can figure about
150 lbs. (68 kg) for each passenger. The total cargo
load must not be more than the vehicles CWR.
Weigh the vehicle with the trailer attached, so
the GVWR or GAWR are not exceeded. If using a
weight-distributing hitch, weigh the vehicle without
the spring bars in place.
The best performance is obtained by correctly spreading
out the weight of the load and choosing the correct
hitch and trailer brakes.
