DODGE RAM 2500 POWER WAGON 2008 3.G Workshop Manual

WARNING!
²Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won't deploy at all.
Always wear your seat belts even though you have
airbags.
²Being too close to the steering wheel or instrument
panel during airbag deployment could cause seri-
ous injury. Airbags need room to inflate. Sit back,
comfortably extending your arms to reach the
steering wheel or instrument panel.
²If the vehicle has window bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.

²Driver and Front Passenger Seat Belt Pretensioners (If
Equipped)
²Driver Seat Track Position Sensor (If Equipped)
²Passenger Side Frontal Airbag ON/OFF Switch (2500/
3500 Standard Cab Vehicles Only)
²Passenger Airbag Disable (PAD) Indicator Light
(2500/3500 Standard Cab Vehicles Only)
How the Airbag System Works
²
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC will not
detect roll over or rear collisions.The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
Also, the ORC turns on the AIRBAG warn-
ing light in the instrument panel for 6 to 8
seconds for a self-check when the ignition is
first turned on. After the self-check, the
AIRBAG warning light will turn off. If the ORC detects
a malfunction in any part of the system, it turns on the
AIRBAG warning light either momentarily or continu-
ously. A single chime will sound if the light comes on
again after initial start up.
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won't have the airbags to
protect you in a collision. If the light does not come
on, stays on after you start the vehicle, or if it comes
on as you drive, have the airbag system checked right
away.
²ThePassenger Airbag Disable (PAD) Indicator Light
(If Equipped)(an amber light located in the center of
the instrument panel) tells the driver and front pas-
senger when the front passenger airbag is turned off.
The PAD Indicator lamp illuminates the words9PASS
AIR BAG OFF9to show that the passenger airbag will
not inflate during a collision requiring airbags. The
PAD light will illuminate when the passenger frontal
airbag has been turned off by using the manual on/offswitch (2500/3500 Standard Cab Vehicles Only). See
Passenger Airbag On/Off Switch ± (2500/3500 Stan-
dard Cab Vehicles Only) in this section for additional
information.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53

collision requiring the airbags, it signals the inflator
units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver's front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger's front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
²TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions. When the ORC
(with side impact option) detects a collision requiringthe window bags to inflate, it signals the inflators on
the crash side of the vehicle. A quantity of nontoxic gas
is generated to inflate the window bag. The inflating
window bag pushes the outside edge of the headliner
out of the way and covers the window. The airbag
inflates in about 30 milliseconds (about one quarter of
the time it takes to blink your eyes) with enough force
to injure you if you are not belted and seated properly,
or if items are positioned in the area where the
window bag inflates. This especially applies to chil-
dren. The window bag is only about 3-1/2 inches (9
cm) thick when it is inflated.
NOTE:At no time should any supplemental restraint
system (SRS) component or SRS related component or
fastener be modified or replaced with any part except
those which are approved by DaimlerChrysler/Mopar.

²TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger, and position every-
one for the best interaction with the front airbag.
Passenger Airbag On/Off Switch ± (2500/3500
Standard Cab Vehicles Only)
The passenger front airbag is to be turned off only if the
passenger:
²is an infant (less than 1 year old) who must ride in the
front seat because there is no rear seat, because the rear
seat is too small for a rear-facing infant restraint or
because the infant has a medical condition which
makes it necessary for the driver to be able to see the
infant,
²is a child, age 1 to 12 who must ride in the front seat
because there is no rear seat, because there is no rear
seat position available, or because the child has a
medical condition which makes it necessary for the
driver to be able to see the child,
²has a medical condition which makes passenger airbag
inflation (deployment) a greater risk for the passenger
than the risk of hitting the dashboard (instrument
panel) or windshield in a crash.

WARNING!
Whenever an airbag is turned off, even a lap/
shoulder belted passenger may hit their head, neck,
or chest on the dashboard (instrument panel) or
windshield in a crash. This may result in serious
injury or death.
To Shut Off the Passenger Airbag (2500/3500 Standard
Cab Vehicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn clockwise, and remove
the key from the switch. This will shut off the passenger
side airbag. The ªOffº light near the switch will illumi-
nate when the ignition switch is turned to the ON
position.To Turn On the Passenger Airbag (2500/3500 Standard
Cab Vehicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn counterclockwise, and
remove the key from the switch. This will turn on the
passenger airbag. The ªOffº light near the switch will be
off when the ignition switch is turned to the ON position.
If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the impact sensors detect a moderate-to-severe
frontal collision, to help restrain the driver and front
passenger, and then immediately deflate.
NOTE:A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If you do have a collision which deploys the airbags, any
or all of the following may occur:
²The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.
However, if you haven't healed significantly within a
few days, or if you have any blistering, see your doctor
immediately. As the airbags deflate you may see some
smoke-like particles. The particles are a normal by-
product of the process that generates the nontoxic gas
used for airbag inflation. These airborne particles may
irritate the skin, eyes, nose, or throat. If you have skin
or eye irritation, rinse the area with cool water. For
nose or throat irritation, move to fresh air. If theirritation continues, see your doctor. If these particles
settle on your clothing, follow the garment manufac-
turer's instructions for cleaning.
²It is not advisable to drive your vehicle after the
airbags have deployed. If you are involved in another
collision, the airbags will not be in place to protect you.
WARNING!
Deployed airbags and seat belt pretensioners (if
equipped) cannot protect you in another collision.
Have the airbags, seat belt pretensioners, and the
front passenger seat belt retractor assembly, replaced
by an authorized dealer as soon as possible.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure,
or add aftermarket side steps or running boards.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.NOTE:
Perchlorate Material ± special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately 5 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system
promptly:
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

²The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
²The light remains on or flickers after the 6 to 8 second
interval.
²The light flickers or comes on and remains on while
driving.
NOTE:If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check fuse block
for blown fuses. Refer to the label located on the inside of
the fuse block cover for the proper airbag fuses. See your
dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to 5-seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment and up to a quarter
second of high-speed deceleration data during and/or
after airbag deployment. EDR data are ONLY recorded if
an airbag deploys and are otherwise unavailable.
NOTE:
1. Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may be
used by DaimlerChrysler Corporation and others to learn
more about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59
2

be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be
provided to the custodial entity upon request. General
data that does not identify particular vehicles or crashes
may be released for incorporation in aggregate crash
databases, such as those maintained by the US govern-
ment and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidentialdata will not be disclosed by DaimlerChrysler
Corporation to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product
3. Requested by police under a legal warrant
4. Otherwise required by law
Data Parameters that May Be Recorded:
²Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
²Airbag disable lamp status (if equipped)
