Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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 is 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.
Run your engine only as long as you must. This saves
fuel. When
you run the engine, make it 90 a little faster
than
just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged.
You will need a well-charged battery to
restart the vehicle. and possibly for signaling later on
with your headlamps. Let the heater
run for a while.
Then. shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when
you feel really uncomfortable
from the
cold. But do it as little as possible. Preserve the
fuel
as long as you can. To help keep warm. you can get
out of the vehicle
and do some fairly vigorous exercises
every
half hour or so until help comes.

The light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver’s
side corner frame crossmember on four-door vehicles.
The heavy-duty trailer wiring has
a 30-amp feed wire
with an inline
fuse located by the junction block. See
“Fuses and Circuit Breakers”
in the Index. Both
harnesses have no connector and should be wired by a
qualified electrical technician. The technician can
use
the following color code chart when connecting the
wiring harness
to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
0 Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
0 Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
0 White (Light Gage): Auxiliary stoplamp.
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 doesn‘t bend or break, but
not so loose that it drags on the ground. Store the
harness in its original place. Wrap the harness together
and tie
it neatly so it won’t be damaged.

can reach. but be sure the vehicles aren't touching
each other.
If they are, it could cause a ground
connection
you don't want. You wouldn't be able to
start your vehicle. and the bad grounding could
damage the electrical systems.
You could be injured if the vehicles roll. Set the
parking brake firmly on each vehicle. Put
an
automatic transmission in PARK (Pj or a manual
transmission
in NEUTRAL (N). If you have a
four-wheel-drive vehicle with a manual transfer case
shift lever. be sure the transfer case is not
in
NEUTRAL (N).

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 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. 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

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 basic

Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth,
you can destroy your transmission.
For information about using tire chains on your vehicle,
see “Tire Chains”
in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear
the area around your front wheels. Then shift back
and forth between
REVERSE (R) and a forward gear
(or with a manual transmission, between FIRST ( 1) or
SECOND (2) and REVERSE(R)), spinning the wheels
as little as possible. Release the accelerator pedal while
you shift, and press lightly on the accelerator pedal
when the transmission is
in gear. If that doesn’t get you
out after a few tries, you may need to be towed out.
Or, you can use your recovery hooks if your vehicle has
them. If you do need to be towed out, see ”Towing
Your Vehicle”
in the Index.
Using the Recovery Hooks
P
Your vehicle may be equipped with recovery hooks.
The recovery
hooks are provided at the front of your
vehicle. You may need to use them
if you’re stuck
off-road and need
to be pulled to some place where you
can continue driving.

painted surfaces as soon as possible. See "Cleaning the
Outside
of Your Vehicle" in the Index.
When you
put the cap back on, turn it to the right
(clockwise)
until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine
if the fuel cap has been left off or improperly
installed. This would allow fuel
to evaporate into the
atmosphere. See "Malfunction Indicator Lamp"
in
the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer
can get one for you. If you get
the wrong type, it may not
fit properly. This may
cause your malfunction indicator lamp to light and your fuel tank and emissions system may be
damaged. See "Malfunction Indicator Lamp"
in
the Index.
Checking Things Under the Hood

Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind
of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
I. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level
up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play (1/4 inch to
112 inch or 6 mm to 12 mm) in the pedal is normal.
It isn’t a good idea
to “top off’ your clutch fluid. Adding
fluid won’t correct a leak.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule, Owner Checks and
Services, to determine how often you should check the
fluid level in your clutch master cylinder reservoir and
for the proper fluid. See “Owner Checks and Services”
and “Recommended Fluids and Lubricants” in
the Index.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This cooIant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240
000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and
how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A 50/50 mixture of water and the DEX-COOL@ coolant
for your vehicle will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
J
they should.
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
I the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused
by the use
of coolant other than DEX-COOL@ is not
covered
by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture.

Downloaded from www.Manualslib.com manuals search engine I A CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have a crash.
Using tires of different sizes may
also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for use on
your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by
the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only
to vehicles sold in the United States.) The
grades are molded on the sidewalls
of most passenger
car tires.
The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or
to some lirnited-production tires.
While the tires available
on General Motors passenger
cars and light trucks may vary with respect
to these
grades, they must also conform
to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon
the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences
in
road characteristics and climate.
