DODGE RAM 2500 DIESEL 2009 4.G Workshop Manual

The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate-to-
severe frontal collisions.
If your vehicle is so equipped, the window bag on the
crash side of the vehicle is triggered in moderate-to-
severe side collisions. But even in collisions where the
airbags work, you need the seat belts to keep you in the
right position for the airbags to protect you properly.
Here are some simple steps you can follow to minimize
the risk of harm from a deploying airbag:
1. Children 12 years and younger should always ride
buckled up in a rear seat in an appropriate child restraint.
WARNING!
Infants in rear-facing child restraints should NEVER
ride in the front seat of a vehicle with a passenger
front airbag, unless the airbag is turned off (2500/
3500 Regular Cab Vehicles Only). An airbag deploy-
ment can cause severe injury or death to infants in
that position. See the Passenger Airbag ON/OFF
Switch section.
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2. If your vehicle does not have a rear seat, see the
Passenger Airbag ON/OFF Switch section.
3. Children that are not big enough to properly wear the
vehicle seat belt (see section on Child Restraints) should
be secured in the rear seat in child restraints or belt-
positioning booster seats. Older children who do not useTHINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

child restraints or belt-positioning booster seats, should
ride properly buckled up in the rear seat. Never allow
children to slide the shoulder belt behind them or under
their arm.
4. All occupants should use their lap and shoulder belts
properly.
5. The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to inflate.
6. If your vehicle has window bags, do not lean against
the door or window, airbags will inflate forcefully into
the space between you and the door.
7. If the airbag system in this vehicle needs to be
modified to accommodate a disabled person, contact the
Customer Center. Phone numbers are provided in theIf
You Need Customer Assistance section later in this
owner’s manual.
WARNING!
•
Relying 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.
•
Being 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.
•
If 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.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag System ComponentsThe airbag system consists of the following:•
Occupant Restraint Controller (ORC)
•
Side Remote Acceleration Sensors (if equipped)
•
Airbag Warning Light
•
Driver Airbag
•
Passenger Airbag
•
Window Bags above Side Windows (if equipped)
•
Steering Wheel and Column
•
Instrument Panel
•
Interconnecting Wiring
•
Knee Impact Bolsters
•
Front Acceleration Sensors (1500 Vehicles Only)
•
Driver and Front Passenger Seat Belt Pretensioners (if
equipped)
•
Driver Seat Track Position Sensor (if equipped)
•
Passenger Side Frontal Airbag ON/OFF Switch (2500/
3500 Regular Cab Vehicles Only)
•
Passenger Airbag Disable (PAD) Indicator Light
(2500/3500 Regular Cab Vehicles Only)
How the Airbag System Works
•
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 information provided by the ORC. The ORC will
not detect rollover or rear collisions.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is inTHINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51

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.
•
The ORC also turns on the Airbag Warning
Light in the instrument panel for six to eight
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 startup.
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.•
The Passenger 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 light illuminates the words PASS
AIR BAG OFF to 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/OFF switch (2500/3500 Regular Cab Vehicles
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Only). See Passenger Airbag ON/OFF Switch – (2500/
3500 Regular Cab Vehicles Only) in this section for
additional information.
•
TheDriver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a collision requiring the airbags, it signals the inflator
units. A large quantity of non-toxic 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.
•
The
Side Impact SRS Window Bags are designed to
activate only in certain side collisions. When the ORC
(with side impact option) detects a collision requiring
Passenger Airbag Disable (PAD) Indicator Light

the window bags to inflate, it signals the inflators on
the crash side of the vehicle. A quantity of non-toxic
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 children. The window bag is only about 3-1/2 in
(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 Chrysler LLC/Mopar.
•
The Knee Impact Bolsters help protect the knees of
the driver and the front passenger, and positions them
for the best interaction with the front airbag.

Regular Cab Vehicles Only)
Passenger Airbag On/Off Switch
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The passenger front airbag is to be turned off only if the
passenger:•
is an infant (less than one 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;
•
is 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;
•
has 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 Regular
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 OFF light near the switch will illuminate
when the ignition switch is turned to the ON position.THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

To Turn On the Passenger Airbag (2500/3500 Regular
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 OFF light near the switch will be
off when the ignition switch is turned to the ON position.If a Deployment OccursThe 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. If you do have a collision which deploys the airbags, any
or all of the following may occur:
•
The 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 non-toxic 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 the
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

irritation continues, see your doctor. If these particles
settle on your clothing, follow the garment manufac-
turer’s instructions for cleaning.
•
It 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!
•
Modifications 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.
•
You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
•
It 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.THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 57

NOTE:
Perchlorate Material – special handling may
apply, see www.dtsc.ca.gov/hazardouswaste/perchlorate
Enhanced Accident Response SystemIf the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately five seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.Airbag Warning 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:
•
The Airbag Warning Light does not come on or flickers
during the six to eight seconds when the ignition
switch is first turned ON.
•
The light remains on or flickers after the six to eight-
second interval.
•
The 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
authorized dealer if the fuse is good.
Event Data Recorder (EDR)In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to a quarter second of high-speed
deceleration data during and/or after airbag deploy-
