Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of air are sucked into the fuel line causing a misfire.
The system can detect this. Adding fuel should correct
this condition. Make sure to install the fuel cap properly.
See ªFilling Your Tankº in the Index. It will take a
few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See ªFuelº in the Index. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start
-up, stalling
when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the CHECK
ENGINE light is on or not working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still
does not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center
to prepare the vehicle for inspection.

2-76 Oil Pressure Light
If you have a problem
with your oil, this light
may stay on after you start
your engine, or come on
when you are driving.
A warning chime and the DIC message LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The oil light could also come on briefly when the
ignition is on but the engine is not running. The light
will come on as a test to show you it is working, but
the light will go out about five seconds after you turn
the ignition to START. If it doesn't come on with the
ignition on, you may have a problem with the fuse or
bulb. Have it fixed right away.CAUTION:
Don't keep driving if the oil pressure is low. If you
do, your engine can become so hot that it catches
fire. You or others could be burned. Check your oil
as soon as possible and have your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by your warranty.

Driver Information Center (DIC)
The Driver Information Center (DIC) displays
information in either English or metric. When the
system is on or off, push the ON/OFF button down
for three seconds to change the display between English
and metric. This will also change the digital screen for
the climate control system between English and metric.The DIC has different display modes which can be
accessed by pressing the four buttons on the DIC.
These buttons are labeled ON/OFF, SELECT right
arrow, SELECT down arrow and RESET. The button
functions are detailed in the following.
Turn on the system by pressing the ON/OFF button
once. When you turn on the ignition, the DIC will be in
the mode last displayed when the engine was turned off.
Keep in mind that this also applies to the OFF mode.
To turn off messages on the DIC (except LOW OIL
PRESSURE, LOW BRAKE FLUID, PARK BRAKE
SET, STARTING DISABLED and the HOT...STOP
ENGINE warning), press the RESET button.
Pressing the SELECT right arrow button will allow
you to access the following modes, DATE/ET, FUEL,
ECON, OIL and GAGE. While in any of these modes,
warning messages can interrupt and take over the
display until you acknowledge the message, or the
condition causing the problem goes away.

2-81 Oil Life
The GM Oil Life System
is the only function
accessible in the OIL mode. Engine oil life is displayed
in a reading such as:
OIL LIFE 30%
This is an estimate of the oil's remaining useful life.
It will show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with this message:
CHANGE OIL SOON
When the oil life is down to zero, you will receive
this message:
CHANGE OIL NOW
Always reset the OIL LIFE reminder after an oil change.
To reset the Oil Life System, see ªOil Life Systemº in
the Index. Also, see ªEngine Oil, When to Changeº in
the Index.Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It can't be reset accurately until the next oil change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule
in this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive in dusty areas, change your
oil after every 3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine. So,
be sure to check your oil level often. See ªEngine Oilº
in the Index.

2-90 DIC Warnings and Messages
Other messages or warnings may appear in the DIC
display. For Canadian drivers, in addition to the DIC
message your DIC will display EXP with a number after
it which reflects the following messages:

2-91
CHECK OIL LEVEL - 5: If you ever see the
CHECK OIL LEVEL message, it indicates that the
engine oil level is 1 to 1 1/2 quarts (0.9 L to 1.4 L) low.
The message will appear only if the engine is running
and it has been at least eight minutes since the engine
was last running. If the message appears, check the oil
dipstick level. If it reads low, your oil level should be
brought up to the proper level (see ªEngine Oilº in
the Index). After bringing the oil to the proper level,
the ignition must be off for eight minutes to allow the
majority of oil to drain into the oil pan.
SERV STABILITY SYS
- 26 : If you ever see the
SERV STABILITY SYS message, it means there
may be a problem with your stability enhancement
system. If you see this message, try to reset the system
(stop; turn off the engine; then start the engine again).
If the SERV STABILITY SYS message still comes on,
it means there is a problem. You should see your dealer
for service. Reduce your speed and drive accordingly.STABILITY ACTIVE
- 42 : You may see the
STABILITY ACTIVE message on the Driver
Information Center. It means that an advanced,
computer
-controlled system has come on to help
your vehicle continue to go in the direction in which
you're steering. This stability enhancement system
activates when the computer senses that your vehicle is
just starting to spin, as it might if you hit a patch of ice
or other slippery spot on the road. When the system is
on, you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY ACTIVE message comes on, you'll know
that something has caused your vehicle to start to spin,
so you should consider slowing down.

Automatic Operation
Press the AUTO
-PUSH knob when you want the
system to automatically adjust the interior temperature
to your preference. When the system is set for automatic
operation, air will come from the floor, the panel outlets
or the windshield outlets depending on the temperature
inside the vehicle, the outside temperature, the engine
coolant temperature and the sun load. Fan speed will
vary as the system reaches and maintains the comfort
setting you have selected.
To find your comfort setting, start with the system in
automatic mode by pressing the AUTO
-PUSH knob.
Adjust the comfort setting by using the red and blue
buttons located below the digital display until you
reach a setting of 75
F (24
C) on the display. Give the
vehicle about 30 minutes to stabilize and then readjust
the comfort setting if necessary. The display will show
the comfort setting for five seconds and then it will
show the outside temperature.In cold weather, the system will delay turning on the
fan to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Turning the AUTO FAN knob
will override this delay by turning off the automatic fan
mode and changing the fan speed.
Your automatic electronic climate control system has a
sun sensor located on the top of the instrument panel
that detects direct sunlight. To keep you and your
passengers comfortable, the system may supply cooler
air to the side toward the sun. Be careful not to put
anything over this sun sensor. The automatic electronic
climate control system may not operate correctly if this
sensor is covered.
To change the automatic electronic climate control
display from an English display to a metric display,
push the OFF button located in the Driver Information
Center (DIC) for two seconds. The display in the DIC
will also change from an English to a metric display. To
return to an English display, repeat the above procedure.

3-6
RECIRC: Press this button to limit the amount
of outside air entering your vehicle. This is helpful when
you are trying to cool the interior of the vehicle quickly
or limit the amount of outside air entering your vehicle
for some other reason. The RECIRC button and the
AUTO
-PUSH knob may be selected at the same time.
The system will remain in RECIRC until the ignition
is turned off, then the system will return back to the
previously selected mode. RECIRC may be selected
in all manual airflow modes except front defrost.
When the weather is cool or damp, operating in
RECIRC for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
switch back to outside air by turning off RECIRC,
select either DEFOG or front defrost mode and increase
the fan speed. To avoid refogging of the windows,
minimize your use of RECIRC under these conditions
and turn the A/C on to help dehumidify the air.
A/C: Press this button to turn the air conditioning
compressor on and off. If the system is operating in
the automatic mode, the A/C indicator light will
automatically illuminate. In the auto mode, the
A/C compressor will only operate when the system
determines it is needed.OFF: Turn the AUTO
-PUSH knob to OFF. Turning
the system off will cause the fan to turn off and the
airflow to be directed out the lower floor outlets. The
system will still try to keep the interior of the vehicle
at the previously chosen comfort setting. The outside
temperature will show in the display when the system
is set to OFF.
Air Conditioning
The air conditioner cools and dehumidifies the air for
the inside of the vehicle.
The air conditioning compressor is enabled in all
modes unless the A/C button is in the off position
(the indicator light will not be illuminated). However,
the air conditioning compressor will not operate when
the outside temperature is below 34
F (1
C). When
the air conditioner is on, you may sometimes notice
slight changes in your vehicle's engine speed and power.
This is normal, because the system is designed to cycle
the compressor on and off to keep the desired cooling
and help fuel economy.

3-7
On very hot days, open the windows long enough to
let the hot air out. This reduces the time required to
cool the interior of the vehicle to a comfortable level.
If the system is in the automatic mode (AUTO
-PUSH
knob indicator light is on), during very hot days the
system will automatically go to the RECIRC mode and
the temperature door will initially be at the full cold
position for maximum cooling. You can choose the
extreme comfort setting of 60
F (16
C), but the
system will not cool any faster by choosing the extreme
comfort setting.
Heating
In cold weather, if the automatic mode is selected
(AUTO
-PUSH knob indicator light is on), the system
will automatically direct the airflow out of the lower
floor outlets and the temperature door will initially be
positioned at the full hot position. You can choose the
extreme comfort setting of 90
F (32
C), but the
system will not warm up any faster by selecting the
extreme comfort setting.In cold weather, the system will delay turning on the
fan to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. The fan speed will increase as the
temperature of the engine coolant increases. Turning the
AUTO FAN knob will override this delay by turning
off the automatic fan control mode and changing the
fan speed.
Defogging and Defrosting
On cool, humid days, use the defog setting to keep
the windows clear while also providing heat through the
lower outlets. Turn the AUTO
-PUSH knob clockwise to
DEF to quickly remove fog or ice from the windshield.
For maximum front defrost performance under extreme
icing or frosting conditions, increase the temperature
setting to 90
F (33
C) and increase the fan speed
to high.

3-10 Steering Wheel Controls for Climate Control
Some heating and cooling
controls can be adjusted
at the steering wheel.
Other touch controls
also operate some audio
controls. See ªAudio
Steering Wheel Controlsº
later in this section.
Press the upper part of the fan symbol button to override
the automatic fan control and increase the fan speed.
Press the lower part of the fan symbol button to override
the automatic fan control and reduce the fan speed.
Press either arrow on the TEMP button once to display
your current comfort setting in the digital display. Press
the upper part of the TEMP button again to provide a
warmer comfort setting or press the lower part of the
TEMP button again to provide a cooler comfort setting.

and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all its controls, to be sure you're getting the
most out of the advanced engineering that went into it.
Setting the Clock
Press and hold HR until the correct hour appears. The
letters AM or PM will appear on the display. Then, press
and hold MN until the correct minute appears. The clock
may be set with the ignition on or off. In addition, the
