Advanced Front Air Bags
This vehicle has Advanced Front Air Bags for both the
driver and front passenger as a supplement to the seat
belt restraint systems. The driver ’s Advanced Front Air
Bag is mounted in the center of the steering wheel. The
passenger ’s Advanced Front Air Bag is mounted in the
instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on
the air bag covers. Advanced Front Air Bag And Knee Bolster Locations 1 — Driver And Passenger Advanced Front Air Bags
2 — Driver/Passenger Knee Impact Bolsters 2THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 69

WARNING!• Being too close to the steering wheel or instrument
panel during Advanced Front Air Bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfortably
extending your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced 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. Advanced 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
determined 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
Advanced Front Air Bags.70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced 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 Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The 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 Advanced 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.
Supplemental Side Air Bags — If Equipped
Your vehicle may be equipped with two types of side air
bags:
1. Supplemental Seat-Mounted Side Air Bags (SABs) (If
Equipped): Located in the outboard side of the front72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Seat belts (and child restraints where appropriate) are
necessary for your protection in all collisions. They also
help keep you in position, away from inflating Side Air
Bags. 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 restraint 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. (Continued) WARNING! (Continued)• 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.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Side Impacts (If Equipped Side Air Bags)
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 impact76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to ParkSense System
Usage Precautions for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. When in REVERSE and above the system’s oper-
ating speed, a warning will appear within the Electronic
Vehicle Information Center (EVIC) or Driver Information Display (DID) indicating the vehicle speed is too fast. The
system will become active again if the vehicle speed is
decreased to speeds less than approximately 6 mph
(9 km/h).
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab vehicles, the rear
ParkSense sensors are shipped loose. Please Refer to the
Ram Body Builders Guide for more information.
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 18 in (45 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle. 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 187

The ParkSense switch LED will be ON when ParkSense is
disabled or defective. The ParkSense switch LED will be
OFF when the system is enabled.
If the ParkSense switch is pushed, and the system is
disabled or requires service, the ParkSense switch LED
will blink momentarily, and then the LED will be ON.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the
instrument cluster will actuate a single chime, once per
ignition cycle, and it will display the  PARKSENSE
UNAVAILABLE WIPE REAR SENSORS  or the
 PARKSENSE UNAVAILABLE SERVICE REQUIRED 
message. Refer to “Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID)” in “Under-
standing Your Instrument Panel” for further information.
When the gear selector is moved to REVERSE and the
system has detected a faulted condition, the EVIC/DID will display the  PARKSENSE UNAVAILABLE WIPE
REAR SENSORS  or the  PARKSENSE UNAVAILABLE
SERVICE REQUIRED  message for as long as the vehicle
is in REVERSE. Under this condition, ParkSense will not
operate.
If  PARKSENSE UNAVAILABLE WIPE REAR SENSORS 
appears in the Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID) make sure
the outer surface and the underside of the rear fascia/
bumper is clean and clear of snow, ice, mud, dirt or other
obstruction, and then cycle the ignition. If the message
continues to appear, see an authorized dealer.
If  PARKSENSE UNAVAILABLE SERVICE REQUIRED 
appears in the EVIC/DID, see your authorized dealer. 3UNDERSTANDING THE FEATURES OF YOUR VEHICLE 193
