Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option)
-
In very cold weather, 0°F (- 1 SOC) or colder, the engine
coolant heater can help.
You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged
in a minimum of
four hours prior to starting your vehicle.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured.
Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. After you’ve used the coolant heater, be sure to store
the cord as it was before to keep it away from moving
engine parts.
If you don’t, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have, and some other things. Instead of
trying to list everything here, we
ask that you contact a
GM dealer in the area where you’ll be parking your
vehicle. The dealer can give
you the best advice for that
particular area.

Keep the hood and front air inlet free of ice, snow, or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside
of your windows.
When you enter a vehicle in cold weather, turn the
blower fan to HI for a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance
of fogging the
inside
of your windows.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
Your vehicle has air vents in the center and on the sides
of your instrument panel.
You can move the vents from side
to side or up and
down to direct the flow
of air, or close the vents
altogether. When
you close a vent, it will increase the
flow of air coming out of any vents that are open.
Rear Window Defogger (Option)
You can tell if your vehicle has this option by looking at
the rear window. There will be lines across the glass.
These are the wire-like elements which heat your window.
NOTICE:
Scraping the inside of your rear window could
cut and damage the defogger. Your warranty
would not cover this damage. Don’t put decals
there; you might have to scrape them off.

Downloaded from www.Manualslib.com manuals search engine If your vehicle has more than one battery, use the
battery that is under the hood
of the vehicle -- this
will reduce the electrical resistance.
2. Get the vehicles close enough so the jumper cables
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.
Set the parking brake firmly
on each vehicle. Put an
automatic transmission in
PARK (P) or a manual
transmission
in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Turn off all
lamps that aren’t needed, and radios. This will avoid
sparks and help save both batteries, and could save
your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs would not be covered by
your warranty.
4. Open the hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
A CAUTION:
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 (or batteries) has enough
water. You don’t need to add water to the Delco
Freedom@ battery (or batteries) 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.

You will find a coolant temperature gage on your
vehicle instrument panel.
If you have a diesel engine,
you will also find a low coolant light
on your
instrument panel.
If your vehicle has a diesel engine, see "Engine
Overheating"
in the GM Diesel Engine Supplement.
If Steam Is Coming From Your Engine
--- - >?.
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay
away
from the engine if you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty.

If you get the overheat warning but see or hear no
steam, the problem may
not be too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer. See “Driving on Grades” in the Index.
If
you get the overheat warning with no sign of steam,
try this for a
minute or so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift
to the highest gear while
driving
-- DRIVE (D).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on,
you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked,
to push
the accelerator until the engine speed is about twice as
fast as normal idle speed. Bring
the engine speed back to
normal idle speed after two or three minutes. Now see
if
the warning stops. But then, if you still have the
warning,
turn ofthe engine and get everyone out qf the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

Downloaded from www.Manualslib.com manuals search engine When you put the cap back on, turn it to the right until
you hear at least three clicks. 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.
I 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 or have proper
venting, and your fuel tank and emissions system
might
be damaged.
Checking Things Under the Hood
To open the hood, first pull
this handle inside the
vehicle. It is just in front of
the driver’s side
door frame
near the floor.

1. Open the hood.
2. Locate the rear side of each of the headlamps.
3. Without removing the headlamp assembly itself,
remove the bulb assembly from the back of the
headlamp on the driver's side by turning the bulb
counterclockwise one quarter turn.
4. On the passenger side, turn the bulb clockwise
one-quarter turn. Also, to remove the bulb on the
passenger side,
you will need to move the battery.

repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag covers,
and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
