Maintenance When Trailer Towing
Your vehicle will need service more often
when
you’re
pulling
a
trailer. See the Maintenance Schedule 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 adjustment. 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
A
seven-wire harness
is
stored under the rear end
of
your vehicle. between the frame rails.
An
electrical
connector
will
need to be installed at the trailer end
of
the harness, by a qualified electrical technician. For
additional trailer wiring and towing information please
consult your
GM
dealer. Securely attach the harness to
the
trailer, then tape or strap
it
to your vehicle’s frame
rail.
Be
sure you leave
it
loose
enough
so
the wiring
won’t
bind or break when turning with the trailer, but
not
so
loose that
it
drags on the ground. Store
the
harness
in
its original position. Wrap the harness
together and tie
it
neatly
so
it
won’t
be damaged.
If
you
tow a trailer, your Center High-Mounted Stoplamp
(CHMSL)
may not be properly visible from behind.
You should select a trailer with
a
CHMSL
on
it
or,
if
one
is
not available, have one installed. See your
GM
dealer about how
to
connect your vehicle’s wiring to
a
trailer CHMSL.
