Seats and Restraints 71
The operation of the airbag
system can also be affected
by changing, including
improperly repairing or
replacing, any parts of the
following:
.Airbag system, including
airbag modules, front or side
impact sensors, sensing and
diagnostic module, or airbag
wiring
.Front seats, including
stitching, seams or zippers
.Seat belts
.Steering wheel, instrument
panel, overhead console,
ceiling trim, or pillar
garnish trim
.Inner door seals, including
speakers
Your dealer and the service
manual have information about
the location of the airbag
modules and sensors, sensing
and diagnostic module, and
airbag wiring along with the
proper replacement
procedures. 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). See
Passenger Sensing System
0
66. If the vehicle has rollover
roof-rail airbags, see Different
Size Tires and Wheels
0433
for additional important
information.
If the vehicle must be modified
because you have a disability
and 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, call
Customer Assistance. See
Customer Assistance Offices
0 485.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 0116.

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 fuel
funnel adapter, make sure
that it has been removed. See
“Filling the Tank with a
Portable Gas Can” under
Filling the Tank 0356. 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
Recommended Fuel (LSY
2.0L L4 Turbo Engine) 0354
or
Recommended Fuel (L3B
2.7L L4 Turbo and LF4 3.6L
V6 Twin Turbo Engines)
0 355.
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 0366.
See your dealer if assistance
is needed.

Base LevelUplevel
If equipped, the Lane Keep
Assist Light may display the
following colors:
.Blank: LKA is disabled.
.White: Appears when the
vehicle starts. A steady
white light indicates that
LKA is not ready to assist.
.Green: Appears when LKA is
turned on and ready to
assist. LKA will gently turn
the steering wheel if the
vehicle approaches a
detected lane marking.
.Amber: Appears when LKA is
active. The light flashes
amber as a Lane Departure
Warning (LDW) alert to
indicate that the lane
marking has been
unintentionally crossed.
If the system detects you
are steering intentionally (to
pass or change lanes), the
LDW alert may not display.
LKA will not assist or alert if
the turn signal is active in the
direction of lane departure,
or if LKA detects that you are
accelerating, braking,
or actively steering. See Lane
Keep Assist (LKA) 0351.
