OnStar service is subject to the
OnStar Terms and Conditions
included in the OnStar Glove
Box Kit.
OnStar service requires wireless
communication networks and the
Global Positioning System (GPS) satellite network. Not all OnStar
services are available everywhere
or on all vehicles at all times.
OnStar service can’t work unless
the vehicle is in a place where
OnStar has an agreement with
a wireless service provider for
service in that area, and the
wireless service provider has
coverage, network capacity,
reception, and technology
compatible with OnStar service.
Service involving location
information about the vehicle
can’t work unless GPS signals
are available, unobstructed,
and compatible with the OnStar
hardware. The vehicle has to have
a working electrical system and
adequate battery power for the
OnStar equipment to operate.

2-20 Keys, Doors and Windows
Programming the Power
Windows
If the battery on the vehicle has
been recharged, disconnected,
or is not working, you will need to
reprogram each front power window
for the express-up feature to work.
Before reprogramming, replace or
recharge the vehicle's battery.
To program each front window:
1. With the ignition in ON/RUNor ACC/ACCESSORY, or in
Retained Accessory Power
(RAP), close all doors.
2. Press and hold the power window switch until the window
is fully open.
3. Pull the power window switch up until the window is fully closed.
4. Continue holding the switch up for approximately two seconds
after the window is completely
closed. The window is now reprogrammed.
Repeat the process for the other
windows.
Sun Visors
Pull the sun visor down to block
glare. Detach the sun visor from
the center mount to pivot to the side
window, or to extend along the rod,
if available.
Rear Window Sunshade
On vehicles with a rear window
sunshade, the switch is on the
console to the right of the shifter.
The sunshade only operates
when the ignition is in ON/RUN
or ACC/ACCESSORY.
To open the sunshade, press and
release the switch. The sunshade
will fully extend. To close the
sunshade, press and release the
switch again. The sunshade will
fully close.
If the vehicle is shifted into
R (Reverse) when the sunshade is
extended, it will automatically close.

Seats and Restraints 3-41
Additional Factors Affecting
System Operation
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.
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 on
page 3‑42 for more information
about modifications that can
affect how the system operates.
{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.
To purchase a service manual,
see Service Publications Ordering
Information on page 13‑15.
{WARNING
For up to 10 seconds after the
ignition 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.

5-16 Instruments and Controls
If you are using remote start,
if equipped, to start the vehicle
from a distance, you may not see
the system check. Then, after
several more seconds, the status
indicator will light either the word
ON or OFF to let you know the
status of the right front passenger
frontal airbag.
If the word ON is lit on the
passenger airbag status indicator,
it means that the right front
passenger frontal airbag is
enabled (may inflate).
If the word OFF is lit on the airbag
status indicator, it means that the
passenger sensing system has
turned off the right front passenger
frontal 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
Light on page 5‑14 for more
information, including important
safety information.
Charging System Light
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.
The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is
on could drain the battery.
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.

Instruments and Controls 5-19
Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection, your dealer can
prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system
consists of two hydraulic circuits.
If one circuit is not working, the
remaining circuit can still work to
stop the vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have your brake
system inspected right away.
EnglishMetric
If the vehicle has antilock brakes,
this light should come on when the
vehicle is placed in START. If it does
not, have the vehicle serviced by
your dealer.
