If a person of adult-size is sitting
in the right front passenger’s seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
turn the vehicle off, remove any
additional material from the seat,
such as blankets, cushions, seat
covers, seat heaters or seat
massagers and ask the person
to place the seatback in the fully
upright position, then sit upright
in the seat, centered on the seat
cushion, with the person’s legs
comfortably extended. Restart the
vehicle and have the person remain
in this position for two to three
minutes. This will allow the system
to detect that person and then enable
the right front passenger’s frontal
airbag and seat-mounted side
impact airbag.Safety 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 “Safety Belts” and “Child
Restraints” in the Index for
additional information about
the importance of proper
restraint use.{CAUTION
If the airbag readiness light in
the instrument panel cluster
ever comes on and stays on, 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’s seat may not have
the protection of the airbag(s).
SeeAirbag Readiness Light
on page 4-14for more on this,
including important safety
information.
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.

Page 38 of 304

We recommend that you not use
seat covers or other aftermarket
equipment other than any that GM
has approved for your specic
vehicle. SeeAdding Equipment to
Your Airbag-Equipped Vehicle on
page 1-35for more information about
modications that can affect how the
system operates.
The passenger sensing system may
suppress the airbag deployment
when liquid soaks into the seat.
If this happens, the off indicator
in the passenger airbag status
indicator and the airbag readiness
light on the instrument panel will
be lit. The system should resume
normal operation after the seat is
allowed to dry. If the system operates
incorrectly after the seat has dried,
have your dealer/retailer check the
system.{CAUTION
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 Your
Airbag-Equipped Vehicle
Airbags affect how your vehicle
should be serviced. There are
parts of the airbag system in
several places around your vehicle.
Your dealer/retailer and the service
manual have information about
servicing your vehicle and the airbag
system. To purchase a service
manual, seeService Publications
Ordering Information on page 11-14.
{CAUTION
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an
airbag can still inate during
improper service. You can be
injured if you are close to an
airbag when it inates. 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
qualied to do so.

Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation
of the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.This light comes on briey, as a
check to show it is working, when the
ignition is turned to ON/RUN. If the
light does not come on, see your
dealer/retailer.
If the light stays on it indicates that
there is an OBD II problem and
service is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Heeding the light can
prevent more serious damage to the
vehicle. This system is also designed
to assist the service technician in
correctly diagnosing any malfunction.Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
warranty.
Notice:Modications made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modications to these systems
could lead to costly repairs not
covered by the warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test.

Fuel Gage
Your fuel gage tells you about how
much fuel you have left, when
the ignition is on.
When the indicator nears empty,
the low fuel warning light will come
on. You still have a little fuel left,
but you should get more soon.
SeeLow Fuel Warning Light
on page 4-25for more information.The arrow on the fuel gage points
to the side of the vehicle with
the fuel door.
Here are ve things that some
owners ask about. These are normal
and do not indicate a problem with
your fuel gage:At the service 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.
The indicator moves a little when
you turn a corner or speed up.
The gage goes back to empty
when you turn off the ignition.
The vehicle is driven or parked on
a grade.
Low Fuel Warning Light
This light, below the fuel gage,
should come on briey when the
ignition is turned on as a check to let
you know that the light is working.
This light also comes on when
the fuel tank is low on fuel. When
you add fuel the light should go off.
If it does not, have your vehicle
serviced.

Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of your vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Gasoline Octane
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, you might notice an audible
knocking noise when you drive,
commonly referred to as spark
knock. If this occurs, use a gasoline
rated at 87 octane or higher assoon as possible. If you are using
gasoline rated at 87 octane or higher
and you hear heavy knocking, the
engine needs service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication
D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 8-36for 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 might be
affected. The malfunction indicator
lamp could turn on and your vehicle
might fail a smog-check test. See
Malfunction Indicator Lamp on
page 4-20. If this occurs, return to
your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
