2-82
CHANGE ENGINE OIL - 82: This means that
the life of the engine oil has expired and it should be
changed within 200 miles. See ªEngine Oilº and ªFilter
Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.
CHANGE TRANS FLUID
- 47: This message
will appear when it is time to replace the transaxle fluid.
See the Maintenance Schedule booklet for the proper
fluid and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver
that the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAGE
- 50: This message will appear
when the fuel supply is less than 5 gallons (18.9 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 ªEngine Oilº in the Index.
CHECK WASHER FLUID
- 25: This message
means that you need washer solvent.
DRIVER DOOR AJAR
- 140: This message will
display anytime the key is in ON, the transaxle is not in
PARK (P) and the 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).

2-93
The electronic sensor can be affected by road or engine
heat during idling, slow driving or when the engine is
first stared after a short trip. To ensure proper automatic
climate control operation, the outside air temperature
display may not update as quickly as expected. This is to
allow the air surrounding the outside temperature sensor
to be as close to the actual outside conditions as possible.
This is determined by how much time has elapsed since
the vehicle has been turned off and by vehicle speed.
Continuous Variable Road Sensing
Suspension (CVRSS)
The CVRSS automatically adjusts the ride of your
vehicle. Automatic ride control is achieved through a
computer used to control and monitor the suspension
system. The controller receives input from various
sensors to determine the proper system response.
If the controller detects a problem within the system,
the DIC will display a SERVICE SUSPENSION SYS
message. If this message appears, have your vehicle
serviced at your dealership.
Oil Life Indicator
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 ENGINE OIL LIFE appears.
If you see 99% ENGINE OIL LIFE, 99 percent of your
current oil life remains.
The 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 the oil life is gone and you should
change the oil right away. The system doesn't check how
much oil you have, so you'll still have to check for that.
To see how, see ªEngine Oilº in the Index.
When the oil is changed, you'll need to reset the system.
See ªOil Life Indicator, How to Resetº in the Index.

3-44
The Setup Wizard will guide you through the steps to
create an e
-mail service. You may need to contact your
ISP for the information required to complete the setup.
Receiving and Sending E-Mail
Your radio uses the cellular phone to connect to your
ISP. Make sure the phone is secure and connected.
Begin the modem session by connecting the modem
cable (or serial cable with a null modem) to your
computing device. Press and release the modem door on
the radio near the recessed bumps. Connect the cable to
the radio's 25
-pin connector. Start your e-mail program
and connect to the ISP. The radio will receive the phone
number from your PDA and instruct the phone to dial
the number. While connecting, the audio from your
radio will be briefly muted and you will hear the tones
being generated as the modem establishes a connection.
When the connection is complete, the audio will return.
When you end your e
-mail session your radio will
instruct the phone to hang up.
Cellular Phone Reception
If the reception of the cellular signal weakens the error
rate of the modem will increase. If you are having
difficulty connecting or sending and receiving data the
cellular signal may be too weak. To ensure good signal conditions, the cell phone display should show
a minimum of three to four bars for signal strength.
The volume on the phone handset should be set to
three bars for best results.
Text Based Information Services
Your radio can be used to gather information using
enhanced Radio Data Systems (RDS) while you are out of
the vehicle. The radio can provide text
-based information
such as traffic and weather. This is done through a
nationwide network of FM stations. You do not need to
know which station is providing this service, the radio will
search out the station when not being used. Your dealer
can provide details on how to obtain this service.
You can program the radio to automatically wake up
twice daily, for example, at 7 AM and again at 4:30 PM.
If your vehicle is off, the radio will wake up at these
programmed times to gather the information. Although
the radio is awake and receiving data, it will appear to
be off. There will be no sound or display. It may take
up to 15 minutes for each update. The information
will then be available for review when you enter your
vehicle. If the vehicle is on at the time of the scheduled
update, the update will not be performed. In addition
to the user programmable times, the system will
automatically update the information when you turn
the ignition off and leave the vehicle.

3-45 Programming for News/Information Updates
Your vehicle is delivered with the Communiport
Infotainment radio programmable updates off. You
can program the radio to provide two daily updates.
To program the update times follow these steps:
1. Press and hold the INFO button for approximately
two seconds. This will cause the radio to enter the
programming mode.
2. Press and release the INFO button, UPDATE 1
TIME will appear on the display. Use the HR and
MN buttons to set the time you would like to retrieve
the first news and information update.
3. Press and release the INFO button again, UPDATE
2 TIME will appear on the display. Use the HR and
MN buttons to set the time to retrieve the second
daily news and information update.
The HR button can be used to select OFF if one or both
automatic updates are not required.
If you have not started your vehicle in a couple of days
the radio will switch to a reduced update schedule by
skipping every other update time. After approximately
three days the radio will stop providing information
updates until you restart your vehicle. This is intended
to conserve your vehicle's battery.
Programming for an Immediate
Information Update
To program an immediate news update, press and hold
the INFO button until UPDATE NOW? PRESS RDM
appears on the display. Then press the RDM button while
UPDATE NOW? PRESS RDM is being displayed.
The radio will begin the update by switching to the
FM band, if not already there, and tuning to the service
provider's station. If you are listening to AM, FM or
weather, UPDATING INFO.... will appear on the
display until the update has completed. You can switch
the source to cassette or CD changer or turn the radio
off without interrupting the update.
You can also perform the update while listening to the
cassette player or CD changer. The radio will briefly
display UPDATING INFO...., then return to the
normal display. The radio will beep once to let you
know when the update has completed.
To cancel the update and return to the station you were
listening to, turn the radio off and back on again.

4-38 When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:

Start your engine;

Shift into a gear; and

Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet
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. 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
severe operating conditions. See ªEngine Overheatingº
in the Index.

6-2
Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you much
more about how to service your vehicle than this manual
can. To order the proper service manual, see ªService
and Owner Publicationsº in the Index.
Your vehicle has an air bag system. Before attempting
to do your own service work, see ªServicing Your
Air Bag
-Equipped Vehicleº in the Index.
You should keep a record with all parts receipts and
list the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the
Maintenance Schedule booklet.

6-18
Follow these steps to reinstall the air cleaner assembly:
1. Slide the air cleaner lid into the slots in the bottom of
the air cleaner base.
2. Close the cover and make sure that both latches are
secure and fully engaged.
3. Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
4. Tighten the air duct clamp.
Refer to the Maintenance Schedule to determine when
to replace the air filter.
See ªScheduled Maintenance Servicesº in the
Maintenance Schedule booklet.
CAUTION:
Operating the engine with the air cleaner/filter
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/filter off.
NOTICE:
If the air cleaner/filter 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/filter in place when
you're driving.
