service indicator CHEVROLET MONTE CARLO 2007 6.G Owners Manual

In many crashes severe enough to inate an
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage
may also occur from the right front passenger
airbag.
Airbags are designed to inate only once.
After they inate, you will need some new
parts for the airbag system. If you do not get
them, the airbag system will not be there
to help protect you in another crash. A new
system will include airbag modules and
possibly other parts. The service manual for
your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection
and Event Data Recorders on page 434.
Let only qualied technicians work on your
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer for service.
Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator on the
overhead console will be visible when you turn
your ignition key to RUN or START. The words
ON and OFF or the symbol for on and off, will
be visible during the system check.
If you use remote start to start your vehicle from
a distance, if your vehicle has this feature,
you may not see the system check. When the
system check is complete, either the word ON
or the word OFF, or the symbol for on or the
symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 175.

Ignition Positions
With the ignition key in the ignition, the key can be
turned to four different positions:
Notice:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key and turn
the key only with your hand. Make sure the
key is in all the way. If none of this works,
then your vehicle needs service.A (OFF):This is the only position in which the
ignition key can be inserted or removed. This
position locks the ignition and transaxle. It is a
theft-deterrent feature.
B (ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is
off. To use ACCESSORY, turn the key clockwise.
C (RUN):This position is where the key returns
to after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the
key in the ACCESSORY or RUN position with
the engine off. You may not be able to start your
vehicle if the battery is allowed to drain for an
extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver
Information Center (DIC) will display DRIVER
DOOR OPEN when the driver’s door is opened
if the ignition is in OFF, ACCESSORY and the
key is in the ignition. SeeDIC Warnings and
Messages on page 195for more information.

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s airbag or airbags
are enabled (may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag
and seat-mounted side impact airbag
(if equipped). A child in a rear-facing child
restraint can be seriously injured or killed if
the right front passenger’s airbag inates.
This is because the back of the rear-facing
child restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s airbag or airbags. SeePassenger
Sensing System on page 77for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of an airbag. SeeAirbag
Readiness Light on page 174.

This light will ash for approximately 60 seconds
and then stay on if a problem is detected with
the Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 358
for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent.This may prevent more serious damage to your
vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notice:If you keep driving your vehicle
with this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by
your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system
of your vehicle or the replacement of the
original tires with other than those of the same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and may
cause this light to come on. Modications to
these systems could lead to costly repairs not
covered by your warranty. This may also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 296.

Here are four things that some owners ask
about. None of these show a problem with your
fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the gage indicated. For example, the gage
may have indicated the tank was half full, but
it actually took a little more or less than
half the tank’s capacity to ll the tank.
The gage moves a little when you turn a
corner or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display
located below the speedometer in the instrument
panel cluster. The DIC buttons are located on
the instrument panel, to the right of the instrument
panel cluster.The DIC comes on when the ignition is on. After a
short delay, the DIC will display the information
that was last displayed before the engine was
turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system
problem is detected. The bottom line of the
DIC shows the shift lever position indicator. See
Automatic Transaxle Operation on page 113
for more information.
If your vehicle has these features, the DIC also
displays the compass direction and the outside air
temperature when viewing the trip and fuel
information. The compass direction appears on
the top right corner of the DIC display. The outside
air temperature automatically appears in the
bottom right corner of the DIC display. If there is a
problem with the system that controls the
temperature display, the numbers will be replaced
with dashes. If this occurs, have the vehicle
serviced by your dealer.
The DIC also allows some features to be
customized. SeeDIC Vehicle Customization on
page 203for more information.
186

If your vehicle has the 5.3L V8 engine (VIN
Code C), use premium unleaded gasoline with a
posted octane rating of 91 or higher. You may
also use regular unleaded gasoline rated at
87 octane or higher, but your vehicle’s acceleration
may be slightly reduced, and you may notice a
slight audible knocking noise, commonly referred
to as spark knock. If the octane is less than
87, you may notice a heavy knocking noise when
you drive. If this occurs, use a gasoline rated
at 87 octane or higher as soon as possible.
Otherwise, you might damage your engine.
If you are using gasoline rated at 87 octane or
higher and you hear heavy knocking, your engine
needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 in Canada. Some gasolines may
contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl
(MMT). General Motors recommends against the
use of gasolines containing MMT. SeeAdditives
on page 300for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate
on fuels that meet California specications.
See the underhood emission control label.
If this fuel is not available in states adopting
California emissions standards, your vehicle will
operate satisfactorily on fuels meeting federal
specications, but emission control system
performance may be affected. The malfunction
indicator lamp may turn on and your vehicle may
fail a smog-check test. SeeMalfunction Indicator
Lamp on page 181. If this occurs, return to
your authorized GM dealer for diagnosis. If it is
determined that the condition is caused by the
type of fuel used, repairs may not be covered
by your warranty.
299

Additives
To provide cleaner air, all gasolines in the
United States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your
fuel. However, some gasolines contain only the
minimum amount of additive required to meet
U.S. Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves
clean, or if your vehicle experiences problems due
to dirty injectors or valves, look for gasoline that
is advertised as TOP TIER Detergent Gasoline.
Also, your dealer has additives that will help
correct and prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may
be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specications described earlier.
However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must not
be used in vehicles that were not designed for
those fuels.Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in your fuel system and also damage
the plastic and rubber parts. That damage
would not be covered under your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
300

When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when they
are cold. SeeLoading Your Vehicle on page 277,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 357.
Your vehicle’s TPMS system can warn you about a
low tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 362andTires on page 349.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
If the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM will be shown on the DIC
display. If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message will be displayed. Once you re-install the
TPMS sensors, the error message should go
off. See your GM dealer for service if all TPMS
sensors are installed and the error message
comes on and stays on.
TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires,
the identication codes will need to be matched
to the new tire/wheel position. The sensors
are matched, to the tire/wheel positions, in the
following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and
driver’s side rear tire using a TPMS diagnostic
tool. See your GM dealer for service.
