Ram 3500 2017 Repair Manual

WARNING!(Continued)
•Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions. This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
WARNING!
•
No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.The steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The
front air bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and front passenger, and position the front occu-
pants for improved interaction with the front air bags.
WARNING!
•
Do not drill, cut, or tamper with the knee impact
bolsters in any way.
• Do not mount any accessories to the knee impact
bolsters such as alarm lights, stereos, citizen band
radios, etc.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Supplemental Side Air Bags
Your vehicle is equipped with two types of side air bags:
1.
Supplemental Seat-Mounted Side Air Bags (SABs): Lo-
cated in the outboard side of the front seats. The SABs are
marked with a “SRS AIRBAG” or “AIRBAG” label sewn
into the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts and/or vehicle rollover events,
in addition to the injury reduction potential provided by
the seat belts and body structure.
When the SAB deploys, it opens the seam on the outboard
side of the seatback’s trim cover. The inflating SAB deploys
through the seat seam into the space between the occupant
and the door. The SAB moves at a very high speed and
with such a high force that it could injure occupants if they
are not seated properly, or if items are positioned in the
area where the SAB inflates. Children are at an even greater
risk of injury from a deploying air bag.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

2.Supplemental Side Air Bag Inflatable Curtains (SABICs):
Located above the side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or “AIRBAG.”
SABICs may help reduce the risk of head or other injuries
to front and rear seat outboard occupants in certain side
impacts and/or vehicle rollover events, in addition to the
injury reduction potential provided by the seat belts and
body structure.The SABICs deploy downward, covering the side win-
dows. An inflating SABIC pushes the outside edge of the
trim out of the way and covers the window. The SABICs
inflate with enough force to injure occupants if they are not
belted and seated properly, or if items are positioned in the
area where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag.
WARNING!
•
Do not stack luggage or other cargo up high enough
to block the deployment of the SABICs. The trim
covering above the side windows where the SABIC
and its deployment path are located should remain
free from any obstructions.
• In order for the SABICs to work as intended, do not
install any accessory items in your vehicle which
could alter the roof. Do not add an aftermarket
sunroof to your vehicle. Do not add roof racks that
require permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.

62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The SABICs and SABs (Side Air Bags) are designed to
activate in certain side impacts and certain rollover events.
The Occupant Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags in a particular
side impact or rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by itself is
not a good indicator of whether or not Side Air Bags should
have deployed.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
•Occupants, including children, who are up against or
very close to Side Air Bags can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or area
where the side air bags inflate, even if they are in an
infant or child restraint.
(Continued)
WARNING! (Continued)
•Seat belts (and child restraints where appropriate) are
necessary for your protection in all collisions. They
also help keep you in position, away from an inflating
Side Air Bag. To get the best protection from the Side
Air Bags, occupants must wear their seat belts properly
and sit upright with their backs against the seats.
Children must be properly restrained in a child re-
straint or booster seat that is appropriate for the size of
the child.
WARNING!
• Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
•
Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 63

NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Side Impacts
In side impacts, the side impact sensors aid the ORC in
determining the appropriate response to impact events.
The system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right side impact deploys the
right Side Air Bags only.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the front air bags
deploy. Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all rollover events. The
rollover sensing-system determines if a rollover event may
be in progress and whether deployment is appropriate. A
slower-developing event may deploy the seat belt preten-
sioners on both sides of the vehicle. A faster-developing
event may deploy the seat belt pretensioners as well as the
Side Air Bags on both sides of the vehicle. The rollover
sensing-system may also deploy the seat belt pretension-
ers, with or without the Side Air Bags, on both sides of the
vehicle if the vehicle experiences a near rollover event.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:
Air Bag System Components
•Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
• Seat Belt Buckle Switch
If A Deployment Occurs
The front air bags are designed to deflate immediately after
deployment. NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is wrong with the
air bag system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
• The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
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 air bags 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 air bag
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 irritation continues,
see your doctor. If these particles settle on your clothing,
follow the garment manufacturer ’s instructions for
cleaning.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will
not be in place to protect you.
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assem-
blies replaced by an authorized dealer immediately.
Also, have the Occupant Restraint Controller System
serviced as well.
NOTE:
• Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
• After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine whether
to have the Enhanced Accident Response System perform
the following functions:
• Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine
compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system could
cause it to fail when you need it. You could be
injured if the air bag system is not there to protect
you. Do not modify the components or wiring, in-
cluding 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.
(Continued)
WARNING! (Continued)
•It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any air
bag system service. If your seat, including your trim
cover and cushion, needs to be serviced in any way
(including removal or loosening/tightening of seat
attachment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accessories
may be used. If it is necessary to modify the air bag
system for persons with disabilities, contact your
authorized dealer.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle dynamics
and safety systems for a short period of time, typically 30
seconds or less. The EDR in this vehicle is designed to
record such data as:
•How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the accel-
erator and/or brake pedal; and,
• How fast the vehicle was traveling.
• These data can help provide a better understanding of
the circumstances in which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no personal
data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforcement,
could combine the EDR data with the type of personally
identifying data routinely acquired during a crash investi-
gation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed. In
addition to the vehicle manufacturer, other parties, such as
law enforcement, that have the special equipment, can read
the information if they have access to the vehicle or the
EDR.
