Trailer Brakes Following Distance
Because you have anti-lock brakes, do not try to
tap into
your vehicle’s brake system.
If you do, both brake
systems won’t work well,
or at all.
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. Stay at least twice
as far behind the vehicle ahead
as you
would when driving your vehicle without a trailer. 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.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer
to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if
possible, have someone guide you.
4-37

Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you have overdrive, you may want to drive in
THIRD (3), instead of DRIVE (D).
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P).
5. Release the regular brakes. PARK (P) yet.
4-39

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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 transaxle fluid (don’t overfill),
engine oil,
drive belts, 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
this information
before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Rear Towing
Tow Limits -- 35 mph (55 k&), 500 miles (800 km)
Use wheel-lift or car-carrier equipment. Additional
ramping may
be required for car-carrier equipment.
Use safety chains and wheel straps. For rear towing,
the parking brakes must be applied.
I NOTICE:
If the vehicle must be towed on the front wheels,
it cannot be towed more than a total of 500 miles
(800 km) for the lifetime of the vehicle.
NOTICE:
Do not tow with sling-type equipment or the rear
bumper fascia will be damaged.
Towing a vehicle over rough surfaces could
damage
a vehicle. Damage can occur from
vehicle
to ground or vehicle to wheel-lift
equipment. To help avoid damage, install
a
towing dolly and raise the vehicle until adequate
clearance
is obtained between the ground and/or
wheel-lift equipment.
Do not attach winch cables or J-hooks to
suspension components when using carcarrier
equipment. Always use T-hooks inserted in
the T-hook slots.

Section 6 Service and Appearance Care
Here you will find information about the care of your vehicle. This section begins with service and fuel informa\
tion,
and then it shows how to check important fluid and lubricant \
levels. There
is also technical information about your
vehicle, and
a part devoted to its appearance care.

NOTICE:
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean
as well as washer fluid.

allows for expansion if freezing occurs.
which could damage the tank if it is
completely full.
Don’t use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
Fill your washer fluid tank only
Brakes
Brake Fluid
P
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only
two reasons why the brake fluid level in the
reservoir might go down. The fxst is that the brake
fluid
goes down to an acceptable level during normal brake
lining wear. When new
linings are put in, the fluid level
goes back
up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fwd, since a leak means that sooner or later your
brakes won’t work well, or won’t work
at all.
6-33

So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid
won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have too much
fluid
when you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done
on the brake hydraulic system.
b -
A CAUTION:
If you have too much brake fluid, it can spill on
the engine. The
fluid will burn if the engine is
hot enough. You or others could be burned, and
your vehicle could be damaged. Add brake
fluid
only when work is done on the brake
hydraulic system.
When your brake fluid falls to
a low level, your brake
warning light will come
on. See “Brake System Warning
Light”
in the Index.
What to Add
When you do need brake fluid, use only
DOT-3 brake
fluid
-- such as Delco Supreme ll@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
I
A CAUTIOP’
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work
at all. This could cause a
crash. Always use the proper brake fluid.
6-34

NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care’’ in
the Index.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make
a high-pitched warning sound when the brake
pads are worn and new pads are needed. The
sound may
come and go or be heard all the time your vehicle is
moving (except when you are pushing on the brake
pedal firmly).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
