Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option)
In very cold weather, 0°F
(- 18 O C j or colder, the
engine coolant heater
can help.
A CAUTION:
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.
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 110-volt AC outlet. ~
4. Before starting the engine, be sure to unplug and
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
your
GM dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

the positive
(+) and negative (-) terminals on
each battery.
I 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 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.

your eyes
or on your skin, flush the place with
water

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
things
you should know. Positive (+) will go to
positive (+) and negative (-) will go to a metal
engine part. Don’t connect positive
(+) to
negative (-) or you’ll get a short that would damage
the battery and maybe other parts too.

You will find a coolant temperature gage on your
vehicle’s instrument panel.
If Steam Is Coming From Your Engine
A CAUTION:
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 you
open 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:
Climb a long hill on a hot day.
0 Stop after high-speed driving.
Idle for long periods in traffic.
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. Turn off your air conditioner.
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
-- AUTOMATIC OVERDRIVE (@) or
DRIVE (D) for automatic transmissions. 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, 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 of the vehicle until it
cools down.
You may decide not to lift the hood but
to get service
help right away.

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.
