roof GMC SAVANA 2008 Owner's Manual

{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. See
Airbag Off Switch on page 1-66for more on
this, including important safety information.
Airbag System
Your vehicle has the following airbag:
•A frontal airbag for the driver.
Your vehicle may have the following airbags:
•A frontal airbag for the right front passenger.
•A roof-rail airbag for the driver (cargo van).
•A roof-rail airbag for the right front passenger
position (cargo or passenger van equipped
with a sliding door).
If you have a passenger van with a right front
passenger roof-rail airbag and a sliding door,
you will also have a separate roof-rail airbag
for the passenger seated directly behind the
right front passenger and the third row outboard
passenger position.
•A roof-rail airbag for the driver, passenger seated
directly behind the driver, and the third row
outboard passenger position (passenger van
equipped with a sliding or hinged door).
•A roof-rail airbag for the right front passenger,
passenger seated directly behind the right
front passenger, and the third row outboard
passenger position (passenger van equipped
with a hinged door).
1-57

All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on
the middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are “supplemental
restraints” to the safety belts. All airbags are
designed to work with safety belts, but do
not replace them.
{CAUTION:
Frontal airbags are designed to deploy in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear crashes, or in many side crashes.
If your vehicle has rollover capable roof-rail
airbags, they are designed to inate in
moderate to severe crashes where something
hits the side of your vehicle and in the event
of a vehicle rollover. They are not designed
to inate in frontal or in rear crashes.
Everyone in your vehicle should wear a
safety belt properly — whether or not there
is an airbag for that person.
1-58

{CAUTION:
Airbags inate with great force, faster than
the blink of an eye. Anyone who is up against,
or very close to, any airbag when it inates
can be seriously injured or killed. Do not sit
unnecessarily close to the airbag, as you
would be if you were sitting on the edge of
your seat or leaning forward. Safety belts
help keep you in position before and during
a crash. Always wear your safety belt, even
with airbags. The driver should sit as far back
as possible while still maintaining control
of the vehicle.
Occupants should not lean on or sleep
against the door or side windows in seating
positions with roof-rail airbags.
{CAUTION:
Airbags plus lap-shoulder belts offer the
best protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and infants
need the protection that a child restraint
system can provide. Always secure children
properly in your vehicle. To read how, see
Older Children on page 1-29orInfants and
Young Children on page 1-32.
There is an airbag
readiness light on
the instrument panel,
which shows the
airbag symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-27
for more information.
1-59

If your vehicle is a cargo or passenger van with
a sliding door and it has a roof-rail airbag for the
driver and right front passenger position, the roof-rail
airbags are in the ceiling above the side window.If your vehicle has roof-rail airbags for the driver,
right front passenger, passengers behind the driver
and right front passenger, and the third row outboard
passengers, the roof-rail airbags are in the ceiling
above the side windows. On the driver’s side of the
vehicle, there is one single roof-rail airbag for either
vehicles with a hinged door or a sliding door. Driver Side shown, Passenger Side similar
Driver Side shown, Passenger Side similar
1-61

For passenger vans with a sliding door, on the
passenger’s side of the vehicle, you will have a separate
roof-rail airbag for the passenger seated directly behind
the right front passenger and the third row outboard
passenger position.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inating airbag must be kept clear.
Do not put anything between an occupant
and an airbag, and do not attach or put
anything on the steering wheel hub or on
or near any other airbag covering.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your vehicle
by routing the rope or tie down through any
door or window opening. If you do, the path
of an inating roof-rail airbag will be blocked.
When Should an Airbag Inate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce
the potential for severe injuries mainly to the driver’s
or right front passenger’s head and chest. However,
they are only designed to inflate if the impact exceeds
a predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash
is likely to be in time for the airbags to inflate and
help restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact,
and how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds.
For example:
•If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
•If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed than
if the vehicle hits an object that does not deform.
1-62

•If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
•If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
Single Stage vs. Dual Stage Airbags
Depending on the weight of your vehicle, you will have
either “Single Stage Airbags” or “Dual Stage Airbags.”
Vehicles that have a passenger sensing system
also have dual stage airbags. SeePassenger Airbag
Status Indicator on page 3-30orPassenger Sensing
System on page 1-69.
If the GVWR (Gross Vehicle Weight Rating) of your
vehicle is 8,500 lb (3 855 kg) or above, your vehicle
may have single stage airbags. If the GVWR is
below 8,500 lb (3 855 kg) then your vehicle may
have dual stage airbags. You can find the GVWR on
the certification label on the rear edge of the driver’s
door. SeeLoading Your Vehicle on page 4-20for
more information.In addition, your vehicle may have dual-stage frontal
airbags. Dual-stage airbags adjust the restraint according
to crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
Your vehicle may or may not have roof-rail airbags.
SeeAirbag System on page 1-57. Roof-rail airbags are
intended to inflate in moderate to severe side crashes.
In addition, these roof-rail airbags are intended to inflate
during a rollover. Roof-rail airbags will inflate if the crash
severity is above the system’s designed threshold level.
The threshold level can vary with specific vehicle design.
Roof-rail airbags are not intended to inflate in frontal
impacts, near-frontal impacts, or rear impacts. All roof-rail
airbags will deploy when either side of the vehicle is
struck.
In any particular crash, no one can say whether an airbag
should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal airbags, inflation is determined by what the
vehicle hits, the angle of the impact, and how quickly the
vehicle slows down. For roof-rail airbags, deployment
is determined by the location and severity of the side
impact.
1-63

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas from the
inflator. Gas from the inflator fills the airbag causing
the bag to break out of the cover and deploy. The
inflator, the airbag, and related hardware are all part
of the airbag module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with roof-rail airbags, there are airbag modules in the
ceiling of the vehicle, near the side windows for the first,
second, and third rows (if equipped). SeeWhere Are
the Airbags? on page 1-60for more information.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the
impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. Roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants in the
outboard seating positions in the first, second, and
third rows, if equipped. The rollover capable roof-rail
airbags are designed to help reduce the risk of full
or partial ejection in rollover events, although no system
can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-62for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an
Airbag Inates?
After the frontal airbags inflate, they quickly deflate,
so quickly that some people may not even realize
an airbag inflated. Roof-rail airbags may still be at
least partially inflated for some time after they deploy.
Some components of the airbag module may be hot for
several minutes. For location of the airbag modules,
seeWhat Makes an Airbag Inflate? on page 1-64.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, your vehicle may have a passenger
sensing system for the right front passenger’s
position, which includes sensors that are part
of the passenger’s 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). SeePassenger Sensing
System on page 1-69.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses
for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out whether
this will affect my airbag system?
A:If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles first sold
in Canada.
The DRL system will come on in daylight when the
following conditions are met:
•The ignition is on.
•The exterior lamps control is in the AUTO position.
•The shift lever is not in PARK (P).
•The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL, turn the exterior lamp control to the
off position and then release it. For vehicles first sold
in Canada, the transmission must be in the PARK
(P) position, before the DRL can be turned off.
Automatic Headlamp System
When it is dark enough outside and the headlamp switch
is in AUTO, the automatic headlamp system will turn on
the headlamps at the normal brightness along with other
lamps such as the taillamps, sidemarker, parking lamps,
roof marker lamps, and the instrument panel lights.
The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then release.
For vehicles first sold in Canada, the transmission must
be in the PARK (P) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of
the instrument panel. Be sure it is not covered, or
the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
There is a delay in the transition between the daytime and
nighttime operation of the Daytime Running Lamps (DRL)
and the automatic headlamp systems so that driving
under bridges or bright overhead street lights does not
affect the system. The DRL and automatic headlamp
system will only be affected when the light sensor sees
a change in lighting lasting longer than the delay.

To calibrate the compass, use the following procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is located. See “Compass
Variance (Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during
the calibration procedure.
2. Press the vehicle information button until
PRESS
VTO CALIBRATE COMPASS displays.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle in tight circles at less
than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is complete.
The DIC display will then return to PRESS
VTO
CALIBRATE COMPASS.
DIC Warnings and Messages
Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that some
action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons on the instrument
panel to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
If your vehicle has the DURAMAX
®Diesel engine, see
the DURAMAX®Diesel manual for more information.
AUTOMATIC LIGHT CONTROL OFF
This message displays when the automatic headlamps
are turned off. SeeExterior Lamps on page 3-13for
more information.
