Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher rpm setting than normal to make sure the
battery charges. High electrical loads may occur when
several of the following are on: headlamps, high beams,
fog lamps, rear window defogger, blower fan, heated
seats and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The accessory power outlet
(1 2-volt) is located on the
front passenger’s side of the vehicle, near the floor
on the console.
Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet.
If it
does, when not using the outlet be sure to cover it with
the protective cap.
The accessory power outlet will only operate when the
ignition is in
ON and for 10 minutes after turning the
ignition
off. If you would like the accessory power outlet
to operate regardless of ignition position, and for
extended periods of time, see “Engine Compartment
Fuse Block under
Fuses and Circuit Breakers on
page 5-92 or contact your dealer.

display. Choosing the coldest or warmest temperature
setting will not cause the system to heat or
cool any
faster.
If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the floor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The length
of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature. if
necessary.

Move the control between the rear outlets up to direct
airflow through the upper outlets. Move the control down
to direct airflow through the floor outlets. Adjust the
direction of the airflow with the levers located in
the center of each rear outlet.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside
of your vehicle more
effectively.

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, drive belt, cooling system
and brake system.
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 this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during

How to Add Fluid Engine Coolant
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See
Part D:
Recommended Fluids and Lubricants on page 6-15.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick.
1, Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn’t take much fluid, generally less than one
pint
(0.5 L). Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@-Ill, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-Ill is
not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How to Check,” earlier in this
section. The
cooling system 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 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 on
page
5-28.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant 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 they
should.
4. When the correct fluid level is obtained, push the
dipstick back in all the way.
5-24
ProCarManuals.com

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
-- 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, drinkable water and
one-half
DEX-COOL@ coolant which won’t damage
aluminum parts.
If you use this coolant mixture,
you don’t need
to add anything else. Adding
a plain water
to your cooling
system can be dangerous. Plain water, or
some other
liquid such as aicohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system
is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others
could be burned. Use a
50/50 mixture of clean,
drinkable water and DEX-COOL@ coolant.
Notice: If you use an improper coolant mixture,
your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty. Too much water
in the mixture can freeze
ana crack ihe engine, raiiiaiur, bakr
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice: If you use the proper coolant, you don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.

ProCarManuals.com

Coolant Surge Tank Pressure Cap
The cooling system pressure cap is located on the
surge tank.
Notice: Your cooling system pressure cap is a
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating.
Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel. Your Driver Information
Center (DIC) will also display messages about engine
overheating. See
Engine Coolant Temperature Gage on
page 3-38.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message HOT STOP
ENGINE is displayed, an overheat
protection mode which alternates firing groups of
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. Driving extended miles
(km) and/or 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 system. See “Engine
Oil” in the
Index.
