Maintenance When Trailer Towing
Your vehicle will need service more often when you are
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important in
trailer operation are automatic transaxle fluid, engine oil,
belts, cooling system and brake system. Each of
these is covered in this manual, and the Index will help
you find them quickly. If you are trailering, it is 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
•
Dark Green: Right Stop/Turn Signal
