Ram 5500 Chassis Cab 2011 Workshop Manual

WARNING!
Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use the
seat belt extender when the lap belt is not long
enough when it is worn low and snug, and in the
recommended seating positions. Remove and store
the extender when not needed.
Driver and Right Front Passenger Supplemental
Restraint System (SRS) – Airbag
This vehicle has airbags for both the driver and front
passenger (if equipped) as a supplement to the seat belt
restraint systems. The driver’s front airbag is mounted in
the center of the steering wheel. The passenger’s front
airbag is mounted in the instrument panel, above the
glove compartment. The words SRS AIRBAG are em-
bossed on the airbag covers.NOTE:
These airbags are certified to the new Federal
regulations for Advanced Airbags.
Airbag and Knee Boltser Location
1 — Driver and Passenger Air-
bag (if equipped) 2 — Knee Boltser
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Advanced Front Airbags have a multistage inflator
design. This allows the airbag to have different rates of
inflation based on the severity and type of collision.
NOTE:Airbag covers may not be obvious in the interior
trim; but they will open during airbag deployment.
Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller (ORC)
•Airbag Warning Light
•Driver Front Airbag
•Front Passenger Airbag — if equipped
•Steering Wheel and Column
•Instrument Panel
•Knee Impact Bolster
Advanced Front Airbag Features
The Advanced Front Airbag system has multistage driver
and front passenger (if equipped) airbags. This system
provides output appropriate to the severity and type of
collision as determined by the Occupant Restraint Con-
troller (ORC).
The first stage inflator is triggered immediately during an
impact that requires airbag deployment. The timing of
the second stage determines whether the output force is
low, medium, or high. If a low output is sufficient to meet
the need, the remaining gas in the inflator is expended.
WARNING!
•No objects should be placed over or near the
airbag on the instrument panel, because any such
objects could cause harm if the vehicle is in a crash
severe enough to cause the airbag to inflate.

WARNING! (Continued)
•Do not put anything on or around the airbag
covers or attempt to open them manually. You may
damage the airbags and you could be injured
because the airbags may no longer be functional.
The protective covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•Do not drill, cut or tamper with the knee bolster in
any way.
•Do not mount any accessories to the knee bolster
such as alarm lights, stereos, citizen band radios,
etc.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position everyone for
the best interaction with the Advanced Front Airbag.Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag:
Children 12 years old and younger should always ride
buckled up in a rear seat.
WARNING!
Infants in rear-facing child restraints should NEVER
ride in the front seat of a vehicle with a passenger
front airbag. An airbag deployment can cause severe
injury or death to infants in that position.
Children that are not big enough to wear the vehicle seat
belt properly (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 use
child restraints or belt-positioning booster seats should
52 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

ride properly buckled up in the rear seat. Never allow
children to slide the shoulder belt behind them or under
their arm.
If a child from 1 to 12 years old (not in a rear facing child
seat) must ride in the front passenger seat, move the seat
as far back as possible and use the proper child restraint.
(Refer to “Child Restraints”)
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
All occupants should ALWAYS wear their lap and shoul-
der belts properly.
The driver and front passenger seats should be moved
back as far as practical to allow the Advanced Front
Airbags room to inflate.If the airbag system in this vehicle needs to be modified
to accommodate a disabled person, contact the Customer
Center. Phone numbers are provided under
If You Need
Assistance.
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 front airbag deployment could cause
serious injury, including death. Airbags need
room to inflate. Sit back, comfortably extending
your arms to reach the steering wheel or instru-
ment panel.

Airbag Deployment Sensors and Controls
Occupant Restraint Controller (ORC)
TheORC is part of a Federally regulated safety system
required for this vehicle.
The ORC determines if deployment of the front airbags in
a frontal collision is required. Based on impact sensor
signals a central electronic ORC deploys the Advanced
Front Airbags, as required, depending on severity and
type of impact.
Advanced Front Airbags are designed to provide addi-
tional protection by supplementing the seat belts in
certain frontal collisions depending on the severity and
type of collision. Advanced Front Airbags are not ex-
pected to reduce the risk of injury in rear, side or rollover
collisions.
The Advanced Front Airbags will not deploy in all frontal
collisions, including some that may produce substantial vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions. On the other
hand, depending on the type and location of impact,
Advanced Front Airbags may deploy in crashes with
little vehicle front-end damage but that produce a severe
initial deceleration.
Because airbag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an airbag should have
deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating airbag.
The ORC monitors the readiness of the electronic parts of
the system whenever the ignition switch is in the START
or ON position. If the key is in the LOCK position, in the
ACC position, or not in the ignition, the airbags are not
on and will not inflate.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The ORC contains a backup power supply system that
may deploy the airbags even if the battery loses power or
it becomes disconnected prior to deployment.Also, the ORC turns on the Airbag Warning
Light in the instrument panel for approxi-
mately 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 continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted. The diagnostics also record the nature of the
malfunction.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.
Driver and Passenger Airbag Inflator Units
The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel (if equipped). 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 Advanced Front Airbags. Differ-
ent airbag inflation rates are possible, based on the
collision type and severity. The steering wheel hub trim
cover and the upper right side of the instrument panel
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

separate and fold out of the way as the bags inflate to
their full size. The bags fully inflate in about 50 to 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 front airbag gas is vented through the vent
holes in the sides of the airbag. The passenger front
airbag gas is vented through the vent holes in the sides of
the airbag. In this way, the airbags do not interfere with
your control of the vehicle.
Enhanced Accident Response System
In the event of an impact causing airbag deployment, 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 follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
If a Deployment Occurs
The airbags are designed to deflate immediately after
deployment.
NOTE:Front airbags will not deploy in all collisions.
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:
•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 orthroat irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles settle on
your clothing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the airbags have de-
ployed. If you are involved in another collision, the
airbags will not be in place to protect you.
WARNING!
Deployed airbags cannot protect you in another col-
lision. Have the airbags replaced by an authorized
dealer as soon as possible. Also, have the Occupant
Restraint Controller (ORC) system serviced as well.

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.
•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.(Continued)
WARNING! (Continued)
•Do not attempt to modify any part of your ad-
vanced airbag system. The airbag may inflate
accidentally or may not function properly if modi-
fications are made. Take your vehicle to an autho-
rized dealer for any advanced airbag system ser-
vice. If your seat, including your trim cover and
cushion, needs to be serviced in any way (includ-
ing removal or loosening/tightening of seat attach-
ment bolts), take the vehicle to your authorized
dealer. Only manufacturer approved seat accesso-
ries may be used. If it is necessary to modify an
advanced airbag system for persons with disabili-
ties, contact your authorized dealer.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag Warning Light
You will want to have the airbags ready to
inflate for your protection in a collision. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system immediately.
•The Airbag Warning Light does not come on for
approximately six to eight seconds when the ignition
switch is first turned ON.
•The light remains on after the approximate four to
six-second interval.
•The light comes on and remains on while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The airbags may
not be ready to inflate for your protection. Promptly
check the 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 list below) in an event data recorder prior to the
moment of airbag deployment, or near deployment (if
applicable), and up to a quarter second of either high-
speed deceleration data or change in velocity during
and/or after airbag deployment or near-deployment.
EDR data is ONLY recorded if an airbag deploys, or
nearly deploys, and is otherwise unavailable.
NOTE:
1. A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually indica-
tive of a crash, but not severe enough to warrant airbag
deployment.
