SEATS AND RESTRAINTS 79
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light0122 for
more information, including
important safety information.
If the On Indicator Is Lit for a
Child Restraint
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag if the system determines
that an infant is present in a child
restraint. If a child restraint has been
installed and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle. 3. Remove any additional items
from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions provided
by the child restraint
manufacturer and refer to
Securing Child Restraints (With the
Safety Belt in the Rear Seat) 095
or Securing Child Restraints (With
the Safety Belt in the Front
Seat) 097.
5. If, after reinstalling the child restraint and restarting the
vehicle, the on indicator is still
lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback is
not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under the
vehicle head restraint. If this
happens, adjust the head
restraint. See Head
Restraints 053. 6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbags for a child in a child
restraint depending upon the
child’s size. It is better to secure
the child restraint in a rear seat.
Never put a rear-facing child
restraint in the front seat, even if
the on indicator is not lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat, but
the off indicator is lit, it could be
because that person is not sitting

SEATS AND RESTRAINTS 81
If the passenger frontal airbag and
passenger knee airbag are turned
on, the on indicator will be lit.
If the passenger seat gets wet, dry the
seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. See Airbag Readiness
Light 0122 for important safety
information.
The on indicator may be lit if an
object, such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device, is put on an unoccupied seat.
If this is not desired, remove the
object from the seat.
{Warning
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system.
{Warning
For up to 10 seconds after the
vehicle is turned off and the battery
is disconnected, an airbag can still
inflate during improper service. You
can be injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag system.
Be sure to follow proper service
procedures, and make sure the
person performing work for you is
qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal,
may keep the airbag system from
working properly. The operation of the
airbag system can also be affected by
changing any parts of the front seats,
safety belts, airbag sensing and
diagnostic module, steering wheel,
instrument panel, any of the airbag
modules, ceiling or pillar garnish trim,
overhead console, front sensors, side
impact sensors, or airbag wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any

object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger Sensing
System 077.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0300 for additional important
information.
If you have to modify your vehicle
because you have a disability and you
have questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, see
your dealer.Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0122.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 073. See
your dealer for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light 0122.

Uplevel Balanced Configuration
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon. Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.
At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.

Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the passenger
sensing system, the pretensioners, the
airbag modules, the wiring, and the
crash sensing and diagnostic module.
For more information on the airbag
system, seeAirbag System 071.
The airbag readiness light comes on
for several seconds when the vehicle is
started. If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
(Continued)
Warning (Continued)
working properly. The airbags in the
vehicle might not inflate in a crash,
or they could even inflate without a
crash. To help avoid injury, have
the vehicle serviced right away.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on. See
Airbag System Messages 0146.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 77 for important safety information.
The passenger airbag status indicator
is in the overhead console.
When the vehicle is started, the
passenger airbag status indicator will
light the symbol for on and off for
several seconds as a system check.
Then, after several more seconds, the
status indicator will light either the on
or off symbol to let you know the
status of the front outboard passenger
frontal airbag and knee airbag.
If the on symbol is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag and knee
airbag are allowed to inflate.
If the off symbol is lit on the airbag
status indicator, it means that the
passenger sensing system has turned
off the front outboard passenger
frontal airbag and knee airbag.
If, after several seconds, both 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.

{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light0122 for
more information, including
important safety information.
Charging System Light
On some vehicles the charging system
light comes on briefly when the
ignition is turned on, but the engine is
not running, as a check to show the
light is working. It should go out when
the engine is started. For vehicles with a reconfigurable cluster, this light may
not come on when the ignition is
turned on.
If the light stays on, or comes on
while driving, there may be a problem
with the electrical charging system.
Have it checked by your dealer.
Driving while this light is on could
drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
See
Battery Voltage and Charging
Messages 0138.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may
require service. The light should come on to show that it is working when
the ignition is in Service Only Mode.
See
Ignition Positions 0196.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.

124 INSTRUMENTS AND CONTROLS
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0248.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless funnel
adapter, make sure that it has
been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0243. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up. If this occurs, change the fuel
brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Fuel0242.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the
vehicle may affect vehicle operation.
See Add-On Electrical Equipment 0246.
See your dealer if assistance is needed.
