Downloaded from www.Manualslib.com manuals search engine Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0
0
0
The rear bumper on your vehicle is not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to it. Use only a frame-mounted
hitch that does not attach to the bumper.
If you’ll be pulling a trailer that, when loaded, will
weigh more than
2,000 lbs. (900 kg), be sure to use a
properly mounted, weight-distributing hitch and
sway control of the proper size. This equipment is
very important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the body
of your
vehicle when you install a trailer hitch? If you do,
then be sure to seal the holes later when you remove
the hitch. If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can get into your
vehicle (see “Carbon Monoxide” in the Index). Dirt
and water can, too.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Because you have anti-lock brakes, don’t try to tap into
your vehicle’s hydraulic brake system. If you do, both
brake systems won’t work well, or at
all. If you tow
more than
1000 lbs. (450 kg), use trailer brakes. Be sure
to follow the instructions that come with the trailer or
from brake manufacturer.
Be sure to read and follow the instructions for the trailer
brakes
so you’ll be able to maintain them properly.

If your vehicle is equipped with the 3,000-lb. (1 360 kg)
trailer towing package option, you will have
a wiring
harness located under the
trunk trim. The harness is a
five-wire harness, with connector.
These trailer-wiring harness color codes should be
followed when connecting it
to your trailer:
WHITE: Direct trailer ground for trailer lamps.
BROWN: Parking lamps.
0 YELLOW Left turn and stoplamps.
GREEN: Right turn and stoplamps.
0 BLUE: Auxiliary circuit.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your
rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are driving is now a good deal longer and not nearly as
responsive as your vehicle
is by itself. Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle
and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working.
This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a tr$ler. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.

terminal cover.
Using
a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the ACDelco Freedom@
battery installed in every new
GM vehicle. But
if a battery has filler caps, be sure the right
amount of fluid is there.
If it is low, add water to
take care
of that first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you. If you accidentally get it in
your eyes or on your
skin, flush the place with
water and get medical help immediately.

from the wheel bolts,
mounting
surfaces and
spare wheel.
-
Rust or dirt on the wheel, or on the parts to
which
it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause an accident. When you change
a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use
a cloth or a paper towel
to do this;
but be sure to use a scraper or wire
brush later,
if you need to, to get all the rust or
dirt off.
A CAJTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
7. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each nut

Operating the engine with the air cleaner off can
cause you or others to be burned, The air cleaner
not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned, Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfke can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under
one or more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain. regularly reaches
90°F (32°C) or higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
0 Use such as limousine service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require change
until
the message CHANGE TRANS FLUID appears
on the Driver Information Center.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks
air, replace it (except some aluminum
wheels, which can sometimes be’repaired). See your
dealer
if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
Each
new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts.
This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your Cadillac model.
Using the wrong replacement wheels, wheel
bolts or wheel nuts on your vehicle can be
dangerous.
It could affect the braking and
handling
of your vehicle, make your tires lose
air and make you lose control. You could have a
collision in which you or others
could be injured.
Always use the correct wheel, wheel bolts and
wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer
or
-odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a Flat Tire” in the Index for
more information.
