I A CAUTION: There are several different positions for the shift lever.
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.
PARK (P): This locks the
front wheels. It’s the best
position to use when you
start the engine because
your vehicle can’t
move easily.
A CAUTION: I
It is dangerous to get out of your vehicle if the
shift lever
is not fully in PARK (P) with the
parking brake
firmly set. Your vehicle can roll.
CAUTION: (Continued)

Downloaded from www.Manualslib.com manuals search engine If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature
Warning Light
This light tells you that the
engine has overheated. You
should stop the car and turn
the engine off as soon
as possible.
A warning chime should also sound if this light comes
on.
As a check, the light should come on for a few
seconds when
you start your engine. In the section
“Problems on the Road,” this manual explains what to
do. See “Engine Overheating” in the Index.
Engine Coolant Temperature Gage
United States
- c.w IF -TEMP
Canada
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, the engine is too hot.
That reading means the same thing
as the warning
light
-- the engine coolant has overheated. In the section
“Problems on the Road,” this manual explains what to
do. See “Engine Overheating” in the Index.

Downloaded from www.Manualslib.com manuals search engine CHECK FUEL GAGE - 50: This message will appear
when the fuel supply is less than
5 gallons (1 8.9 L) and
the display is turned off.
A single chime will also sound
when this message is displayed.
CHECK GAS CAP - 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it’s fully tightened.
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface.
A false CHECK OIL LEVEL message
may appear if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been
off for a short period of time, and
the oil
level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked
on level ground with the engine
off for at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to checking
the oil level, be sure the engine has been off for
a few
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil if necessary. See “Engine
Oil” in the Index.
CHECK WASHER FLUID - 25: This message will
appear to indicate that you need washer solvent.
DRIVER DOOR A JAR - 140: This message will
display anytime the key is in
ON and your driver’s door
is open or ajar.
A chime will also sound when the
vehicle’s speed is greater than
3 mph (4.8 km/h).
DRIVER NO. X (1 OR 2) : This message will appear
when the remote keyless entry is used. The message will
show which driver is activating the personalization
feature. It will only stay on for five seconds.
This message will appear when the engine coolant temperature is over
262 OF ( 128 O C). Stop and allow your
vehicle to idle in
PARK (P) until it cools down and the
message is removed.
Do not increase engine speed
above a normal idle.
If it does not cool down, turn off
the engine and have it serviced before driving it again.
Severe engine damage can result from an overheated
engine. See “Engine Overheating” in the Index.
ENGINE HOT-A/C OFF - 16: This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the
A/C operation will automatically resume.
You can continue to drive your vehicle.
If this message
continues to appear, have the system repaired as soon as
possible to avoid compressor damage.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is sitting out on a hot day and you have it
set on
AUTO, the air will first flow out the floor outlets
for a few seconds. This is normal. This is to remove hot
air from the air outlets.
As the air is cooled, the airflow
will move through the air conditioning outlets.
To avoid blowing cold air in cold weather, the system
will start at reduced fan speeds until warm air is
available. The length of reduction depends on the
outside air temperature, engine coolant temperature
or the time since the engine was last started.
As the
coolant warms up, the blower fan speed will gradually
increase and air will flow from the heater outlets, with
some airflow to the windshield to prevent fogging under
most normal conditions. If you select defrost mode or a
manual fan speed, this function will be skipped.
If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition
cycle cancels recirculation. Defrost will change to
automatic operation when the ignition is shut
off and
then turned back on.
Electronic Solar Sensor Electronic Solar Sensor
The sensor monitors the sun’s solar radiation and is
located near the end of the instrument panel near
the windshield.
The climate control panel uses this information to
automatically make
the necessary temperature and
airflow adjustments to maintain your comfort. The
climate control system may supply cooler air to one side
of your vehicle, if that side is facing the sun. Be careful
not to put anything over the sensor on top
of the dash.

I# Heater: This setting directs warmed air through
the floor outlets. Some warm air is diverted to the
windshield to minimize fogging.
8 FAN: The button with the fan symbol adjusts the
fan speed. Press the up arrow to increase fan speed and
the down arrow to decrease fan speed. Press the AUTO
button to set the fan speed for automatic operation.
If it
is cold outside, the blower may not run in the maximum
high fan speed right away. The system checks the
temperature of the engine coolant to assure it is warm
enough to provide heat. When the engine coolant is
warm, the controller allows the fan to gradually increase
to a higher speed. This prevents cold air from blowing
into the passenger’s compartment. Selecting a manual
fan speed will override this feature.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best. Your A/C setting
may be adjusted automatically or manually.
It may also
be set separately on the passenger’s side from the
driver’s side. See “Climate Control Panel” earlier in
this section.
Heating
Adjust the interior temperature to a comfortable level
and if the fan speed needs adjusting, press the up or
down arrow. Adjusting the fan speed will cancel the
cold air delay.
Outside air will be brought in and sent through the floor,
air conditioning or bi-level outlets. The heater works
best if you keep your windows closed while using it. In
automatic operation, your fan will not run at high speed
to minimize warm-up time.
Defrosting and Defogging
Use defrost (FRONT) on cool and humid days to keep
the windshield and side windows clear. This setting will
remove fog or ice from the windshield quickly in extremely humid or cold conditions. If you desire to
have more air on your feet, move the control to the
defog mode. You may do this by pressing the right or
left arrow on the
MODE button.
Press the fan button’s up or down arrow to control the
blower speed. You may
also adjust the temperature by
turning the TEMP
knob.
Recirculation and the A/C OFF message are not
available in the defrost mode.

You will find an ENGINE COOLANT HOT IDLE
ENGINE message or an ENGINE OVERHEATED
STOP ENGINE message on the Driver Information
Center (DIC). 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
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.
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 (SO km).
Towing a trailer in
the overheat protection mode should
be avoided.

Engine Coolant
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.
B
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).
0 Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
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
-- 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.
6-22

Downloaded from www.Manualslib.com manuals search engine Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine
is cool.
I A CAUTION: I
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
~~
When replacing the surge tank pressure cap, make sure
it is tight.
Surge Tank Pressure Cap
I NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating.
Two and one-half turns are
required to
seal the cap.
If the surge tank pressure cap needs to be replaced, a
GM cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced, a GM
thermostat is recommended.
