82 Seats and Restraints
6. Restart the vehicle andhave the person remain in
this position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard
passenger airbag is turned
off for an adult-sized
occupant, the airbag will not
be able to inflate and help
protect that person in a
crash, resulting in an
increased risk of serious
injury or even death. An
adult-sized occupant should
not ride in the front
outboard passenger seat,
if the passenger airbag OFF
indicator is lit.
Additional Factors
Affecting System
Operation
Seat belts help keep the
passenger in position on the
seat during vehicle maneuvers and braking, which helps the
passenger sensing system
maintain the passenger airbag
status. See
“Seat Belts” and
“Child Restraints” in the Index
for additional information
about the importance of
proper restraint use.
A thick layer of additional
material, such as a blanket or
cushion, or aftermarket
equipment such as seat
covers, seat heaters, and seat
massagers can affect how well
the passenger sensing system
operates. We recommend that
you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle. See
Adding Equipment to the
Airbag-Equipped Vehicle 083
for more information about
modifications that can affect
how the system operates.
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 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. To purchase a service
manual, see Publication
Ordering Information
0476.

Instruments and Controls 135
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
Modifications0363.
If the light is flashing : 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 fuel
funnel adapter, make sure
that it has been removed.
See “Filling the Tank with a
Portable Gas Can” under
Filling the Tank 0344. 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 (2.0L L4
Turbo Engine)
0343 or
Recommended Fuel (3.6L
V6 Engine) 0343.
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 Tire and Loading
Information label also
shows the size of the
original equipment tires (3)
and the recommended cold
tire inflation pressures (4).
For more information
on tires and inflation see
Tires0400 and
Tire Pressure 0408.
There is also important
loading information on the
vehicle Certification/Tire
label. It may show the
Gross Vehicle Weight
Rating (GVWR) and the
Gross Axle Weight Rating
(GAWR) for the front and
rear axle. See
“Certification/Tire Label”
later in this section.
“Steps for Determining
Correct Load Limit– 1.
Locate the statement
"The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs." on
your vehicle’s placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from
XXX kg or XXX lbs.
4.The resulting figure
equals the available
amount of cargo and
luggage load capacity.
For example, if the
"XXX" amount equals
1400 lbs. and there will
be five 150 lb
passengers in your
vehicle, the amount of
available cargo and
luggage load capacity is
650 lbs. (1400-750 (5 x
150) = 650 lbs.)
5.Determine the combined
weight of luggage and
cargo being loaded on
the vehicle. That weight
may not safely exceed
the available cargo and
luggage load capacity
calculated in Step 4.
6.If your vehicle will be
towing a trailer, load
from your trailer will be
transferred to your
vehicle. Consult this
manual to determine
how this reduces the
available cargo and
luggage load capacity of
your vehicle.”

New Vehicle Break-In
Caution
The vehicle does not need
an elaborate break-in. But it
will perform better in the
long run if you follow these
guidelines:
.Do not drive at any one
constant speed, fast or
slow, for the first 800 km
(500 mi). Do not make(Continued)
Caution (Continued)
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.Avoid making hard stops
for the first 300 km
(200 mi) or so. During this
time the new brake linings
are not yet broken in. Hard
stops with new linings can
mean premature wear and
earlier replacement.
Follow this breaking-in
guideline every time you
get new brake linings.
.Do not tow a trailer during
break-in. See Trailer
Towing0351 for the
trailer towing capabilities
of the vehicle and more
information.
Following break-in, engine
speed and load can be
gradually increased. On new vehicles, the various
mechanical and electrical
systems experience a
“break-in”
period during the
first 6 400 km (4,000 mi) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle’s battery to achieve
the best operation of the
vehicle, including fuel economy
and the Stop/Start System.
See Stop/Start System 0259.
