Downloaded from www.Manualslib.com manuals search engine If You’re Caught in a Blizzard
If you are stopped by heavy snow, you
could be in a serious situation. You
should probably stay with your vehicle
unless you know for sure that you are
near help and you can hike through the
snow. Here are some things to do to
summon help and keep yourself and
your passengers safe:
Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert
police that you’ve been stopped by the
snow.
Put on extra clothing or wrap a
blanket around you.
If you have no
blankets or extra clothing, make body
insulators from newspapers, burlap
bags, rags, floor mats-anything you can wrap around yourself
or tuck
under your clothing to keep warm.
but be careful.
You can run the engine to keep warr~,
111 CAUT’olv Snow can trap exhaust gases
under your vehicle. This can
cause deadly
CO (carbon
monoxide) gas to get inside. CO
could overcome you and kill you.
You can’t see it or smell it,
so you
might not know it was in your
vehicle. Clear away snow
from
around the base of your vehicle,
especially any that is blocking your
exhaust pipe. And check around
again from time to time to be sure
snow doesn’t collect there.
Open a window just a little on the
side
of the vehicle that’s away from
the wind. This will help keep
CO
out.

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. Always leave
just enough slack
so you can turn with
your rig. And, never allow safety chains to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the
instructions for the trailer brakes
so
you’ll be able to install, adjust and
maintain them properly. And:
If your vehicle has 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.
Even if your vehicle doesn’t have anti-
lock brakes, don’t tap into your
vehicle’s brake system
if the trailer’s
brake system will use more than
0.02
cubic inch (0.3 cc) of fluid from your
vehicle’s master cylinder. If it does,
both braking systems won’t work
well.
You could even lose your brakes.
Will the trailer brake parts take 3,000
psi (20 650 kPa) of pressure? If not,
the trailer brake system must not be
used with your vehicle.
If everything checks out this far, then
make the brake fluid tap at the upper
rear master cylinder port. But don’t
use copper tubing for this. If you do,
it will bend and finally break
off. Use
steel brake tubing.

Downloaded from www.Manualslib.com manuals search engine 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
so responsive
as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical connector, lights, 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 worling. 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 lights 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 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.

Making Turns
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
I60
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not. It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Your vehicle has bulb warning .lights.
When you plug trailer lights into your
vehicle’s lighting system, its bulb
warning lights may not let you know if
one
of your lights goes out. So, when
you have trailer lights plugged in, be
sure to check your vehicle and trailer
lights from time to time to be sure
they’re all working. Once you disconnect the trailer lights, the bulb
warning lights again can tell you if one
of your vehicle lights
is out.
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 Wh) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
it’s best to drive in
D instead of (or,
as you need to, a lower gear). This will
minimize heat build-up and extend the
life of your transaxle.

Downloaded from www.Manualslib.com manuals search engine 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
P (Park) yet.
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
P (Park).
5. Release the regular brakes.
When You are Ready to Leave After
Parking on a
Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of
the chocks.
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, 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 these sections before you start
your trip.
Check periodically to see that all hitch
nuts and bolts are tight.

Using a match near a battery
4 L can cause battery gas to
explode. Peopk 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 Delco Freedom@ battery
installed in every new GM vehicle.
But if a battery has filler caps, be
sure the right amount of fluid is
there. lf it is low, add wafer to take
care of that first. If you don’t,
explcrsive 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.
5. Check that the jumper cables don’t
have loose or missing insulation.
If
they do, you could get a shock. The
vehicles could be damaged, too.
Before you connect the cables, here are
some things you should know. Positive
(+) will go to positive (+) and negative
(-) will go to negative (-) or a metal
engine part.
Don’t connect
(+) to (-) or you’ll get a
short that would damage the battery
and maybe other parts, too.
Fans or other moving engine
A parts can injure you badly.
Keep your hands away
from
moving parts once the engines are
running.
6. Connect the red positive (+) cable to
the positive
(+) terminal of the
vehicle with the dead battery.
Use a remote positive
(+) terminal if
the vehicle has one.

Ifa Tire Goes Flat
It’s unusual for a tire to “blow OU~,)
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a
skid and may require
the same correction you’d use in a
skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next section
shows how
to use your jacking
equipment to change a
flat tire safely.

Downloaded from www.Manualslib.com manuals search engine Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 kPa). The compact spare is
made to go up to
3,000 miles
(5 000 Inn), so you can finish your trip
and have
your full-size tire repaired or
replaced where
you want. Of course, it’s
best to replace your spare with a full-
size tire as soon as you can. Your spare
will last longer and be in good shape in
case you need it again. Your anti-lock
brake system warning light may come
on when you are driving with a compact
spare. See the
Index under Anti-Lock
Brake System Warning Light.
Don’t use your compact spare on some
other vehicle.
And don’t
mix your compact spare or
wheel with other wheels or tires. They
won’t fit. Keep your spare and its wheel
together.
