1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 11 0-volt AC outlet.
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.
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 dealer
in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

best position
to use when you start the engine because
your vehicle can’t move easily.

This feature lets you know when to change the engine
oil. It’s based on the engine oil temperatures and your
driving patterns.
To see the display, press the INFO
button several times until XX OIL LIFE LEFT appears.
If you see 99% OIL LIFE LEFT, 99 percent of your
current oil life remains.
The Driver Information Center (DIC) may display
a
CHANGE ENGINE OIL message. Always keep
a written record
of the mileage and date when you
changed your
oil. For more information, see the
Maintenance Schedule booklet.
If you see CHANGE
ENGINE OIL, it means that you have less than
10 percent of the oil life left and you should consider
changing your engine oil.
The system should indicate changing the
oil between
3,000 miles (5 000 kmj and 7,500 miles (1 2 500 km).
It may indicate changing the oil before 3.000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven
7.500 miles (1 2 500 km). it
will indicate to change the oil.
If you drive in a dusty
area, you should change your oil every
3.000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing it sooner. The
system doesn’t check
hmt* much oil you have, so you’ll
still have to check for that.
To see how, see “Engine Oil’’
in the Index.
When the oil
is changed. you‘ll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFO button. Then press and hold the INFO RESET
button until the display shows
100% OIL LIFE LEFT.

You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message
on the Driver Information
Center (DIC).
You will also hear a chime. There is also
an engine temperature warning light and/or gage
on the
instrument panel. See “Engine Coolant Temperature
Warning Light” or “Engine Coolant Temperature Gage”
in the Index.
Overheated Engine Protection
Operating
Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED
STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups
of four cylinders helps prevent engine
damage. In this mode, you will notice a loss in power and
engine performance. This operating mode allows
your vehicle to be driven to a safe place
in an
emergency; you may drive
up to 50 miles (80 km).
Towing a trailer in the overheat protection mode
should be avoided.
-~
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change”
in the Index.

Downloaded from www.Manualslib.com manuals search engine What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for
the "Starburst" symbol. This symbol
indicates that
the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does
not carry this Starburst symbol.
If you change your own
oil, be
sure you use oil that
has the Starburst symbol
on the front of the oil
container. If you have your
oil changed for you,
be sure
the oil put into your engine
is American Petroleum
Institute certified for
gasoline engines.
I .I I
You should also use the proper viscosity oil for your
vehicle, as shown in the following
chart:

6-13

Downloaded from www.Manualslib.com manuals search engine As shown in the chart, SAE 1OW-30 is best for your
vehicle. However,
you can use SAE 5W-30 if it’s going
to be colder than
60°F (16°C) before your next oil
change. When it’s very cold, you should use
SAE
5W-30. These numbers on an oil container show its
viscosity, or thickness.
Do not use other viscosity oils,
such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst”
symbol. Failure to use the
recommended oil can result in engine damage not
covered
by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls
below
-20°F (-29”C), consider using either an
SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both
will provide easier cold starting and better protection
for your engine at extremely low temperatures.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if
you think something should be added.
When to Change Engine Oil
Your vehicle has an Oil Life Indicator. This feature
will let
you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t dete.ct dust in the
oil. So, if you
drive in
a dusty area, be sure to change your oil
every
3,000 miles (5 000 krn) or sooner. Remember
to reset the Oil Life Indicator when the oil has been
changed. For more information, see “Oil Life Indicator”
in the Index.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more
of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any
of these
conditions, the fluid and filter do not require change
until the message
CHANGE TRANS FLUID appears
on the Driver Information Center.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant 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 DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
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
the system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner
-0 at
30,000 miles (50 000 km) or 24 months,

use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
