airbag GMC SAVANA 2007 Service Manual

Passenger Safety Belt
Reminder Light
If your vehicle has this feature, several seconds
after the key is turned to RUN or START, a chime
will sound for several seconds to remind the front
passenger to buckle their safety belt. This would
only occur if the passenger airbag is enabled. See
Passenger Sensing System on page 89for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it
will flash for several more.
This light and chime
reminder will be
repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, seeAirbag System on page 78.
This light will come on
when you start your
vehicle, and it will flash
for a few seconds.
Then the light should go
out. This means the
system is ready.
169

If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the light doesn’t come on then, have it fixed so it
will be ready to warn you if there is a problem.
Airbag Off Light
If your vehicle is equipped with an airbag off
switch, when you turn the right front passenger’s
airbag off, the airbag off light will come on and
stay on to remind you that the airbag has
been turned off. This light will go off when you turn
the airbag back on again. SeeAirbag Off Switch
on page 86for more on this, including important
safety information.

{CAUTION:
If the right front passenger’s airbag is
turned off for a person who is not in
a risk group identied by the national
government, that person will not have the
extra protection of an airbag. In a crash,
the airbag will not be able to inate and
help protect the person sitting there.
Do not turn off the passenger’s airbag
unless the person sitting there is in a risk
group identied by the national
government. SeeAirbag Off Switch on
page 86for more on this, including
important safety information.
{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off. If this ever
happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing
child restraint in your vehicle) until you
have your vehicle serviced. SeeAirbag Off
Switch on page 86.
171

Passenger Airbag Status Indicator
If your vehicle has the passenger sensing system,
the instrument panel will have a passenger
airbag status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.If your vehicle has a rear seat, it will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
United StatesCanada
172

If your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, never
put a child in a rear-facing child restraint in the right
front passenger seat unless the passenger airbag
status indicator shows off and the airbag is off. Here
is why:
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be transported
in vehicles with a rear seat that will
accommodate a rear-facing child restraint,
whenever possible.If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that the
right front passenger’s frontal airbag is enabled
(may inflate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger
sensing system has turned off the right front
passenger’s frontal airbag.
173

SeePassenger Sensing System on page 89for
more on this, including important safety information.
If, after several seconds, all 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.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, 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 seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 169.
Charging System Light
This light should come
on briefly when you turn
on the ignition, before
starting the engine, as a
check to show you it
is working.
After the engine starts, the light should go out. If it
stays on or comes on while you are driving, you
may have a problem with your charging system.
It could indicate a problem with the generator drive
belt, or some other charging system problem.
Have it checked right away. Driving while this light
is on could drain your battery.
If you must drive a short distance with this light
on, it helps to turn off all your accessories, such as
the radio and air conditioner.

Service
Your dealer knows your vehicle best and wants
you to be happy with it. We hope you will go
to your dealer for all your service needs. You will
get genuine GM parts and GM-trained and
supported service people.
We hope you will want to keep your GM vehicle
all GM. Genuine GM parts have one of these
marks:
Accessories and Modications
When you add non-GM accessories to your vehicle
they can affect your vehicle’s performance and
safety, including such things as, airbags, braking,
stability, ride and handling, emissions systems,
aerodynamics, durability, and electronic systems
like anti-lock brakes, traction control and stability
control. Some of these accessories may even cause
malfunction or damage not covered by warranty.
GM Accessories are designed to complement and
function with other systems on your vehicle. Your
GM dealer can accessorize your vehicle using
genuine GM Accessories. When you go to your
GM dealer and ask for GM Accessories, you will
know that GM-trained and supported service
technicians will perform the work using genuine
GM Accessories.
California Proposition 65 Warning
Most motor vehicles, including this one, contain
and/or emit chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. Engine exhaust, many parts and
systems (including some inside the vehicle), many
fluids, and some component wear by-products
contain and/or emit these chemicals.

Doing Your Own Service Work
{CAUTION:
You can be injured and your vehicle could
be damaged if you try to do service work
on a vehicle without knowing enough
about it.
Be sure you have sufficient knowledge,
experience, the proper replacement
parts, and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts,
and other fasteners. English and metric
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
If you want to do some of your own service work,
you will want to use the proper service manual.
It tells you much more about how to service your
vehicle than this manual can. To order the
proper service manual, seeService Publications
Ordering Information on page 437.Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle on
page 96.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeeMaintenance Record
on page 413.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your
vehicle can affect the airflow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
287

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 96.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
engine compartment fuse block. An electrical
overload will cause the lamps to flicker on and off,
or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow, etc., the wiper will stop
until the motor cools. Although the circuit is
protected from electrical overload, overload due to
heavy snow, etc., may cause wiper linkage
damage. Always clear ice and heavy snow from
the windshield before using the windshield wipers.
If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new
one of the identical size and rating.
