DODGE DURANGO 2017 3.G Workshop Manual

Seat Belt Pretensioner
The front seat belt system is equipped with pretensioning
devices that are designed to remove slack from the seat belt
in the event of a collision. These devices may improve the
performance of the seat belt by removing slack from the
seat belt early in a collision. Pretensioners work for all size
occupants, including those in child restraints.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Restraint
Controller (ORC). Like the air bags, the pretensioners are
single use items. A deployed pretensioner or a deployed air
bag must be replaced immediately.
Energy Management Feature
This vehicle has a seat belt system with an Energy Man-
agement feature in the front seating positions that may
help further reduce the risk of injury in the event of a
collision. This seat belt system has a retractor assembly that
is designed to release webbing in a controlled manner.
Switchable Automatic Locking Retractor (ALR)
The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) which is used to secure a child restraint system. For
additional information, refer to “Installing Child Restraints
Using The Vehicle Seat Belt” under the “Child Restraints”
section of this manual. The figure below illustrates the
locking feature for each seating position.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear aclick. In Automatic Locking Mode, the shoulder belt is automati-
cally pre-locked. The seat belt will still retract to remove
any slack in the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in a seating
position that has a seat belt with this feature. Children 12
years old and under should always be properly restrained
in a vehicle with a rear seat.
WARNING!
•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.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.

How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it to
retract completely to disengage the Automatic Locking Mode
and activate the vehicle sensitive (emergency) locking mode.
WARNING!
•The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the procedures
in the Service Manual.
• Failure to replace the seat belt assembly could in-
crease the risk of injury in collisions.
•
Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the child.

Front Air Bags
This vehicle has front air bags and lap/shoulder belt for both
the driver and front passenger. The air bags are supplemental
to the seat belt restraint systems. The driver front air bag is
mounted in the center of the steering wheel. The passenger
front air bag is mounted in the instrument panel, above the
glove compartment. The words “SRS AIRBAG” or “AIR-
BAG” are embossed on the air bag covers.WARNING!
•Being too close to the steering wheel or instrument
panel during front air bag deployment 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.
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.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
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.
(Continued)
WARNING! (Continued)
•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.
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.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53

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.
Supplemental Driver Knee Air Bag
This vehicle is equipped with a Supplemental Driver Knee
Air Bag mounted in the instrument panel below the
steering column. The Supplemental Driver Knee Air Bag
provides enhanced protection during a frontal impact by
working together with the seat belts, pretensioners, and
front air bags.
54 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):
Located in the outboard side of the front seats. The
SABs are marked with a “SRS AIRBAG” or “AIR-
BAG” 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.
2. Supplemental Side Air Bag Inflatable Curtains
(SABICs): Located above the side windows. The trim
covering the SABICs is labeled “SRS AIRBAG” or
“AIRBAG.”
Front Supplemental Seat-Mounted Side Air Bag Label

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 55

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 notbelted 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.
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.
•The Air Bag Warning Light
does not come on
during the four to eight seconds when the ignition
switch is first in the ON/RUN position.
• The Air Bag Warning Light remains on after the four to
eight-second interval.
• The Air Bag Warning Light comes on intermittently or
remains on while driving.
Reference the “Air Bag Warning Light” topic in “Supple-
mental Restraint System (SRS)” for further information.
WARNING!
• Your vehicle is equipped with left and right Supple-
mental Side Air Bag Inflatable Curtains (SABICs).
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

WARNING!(Continued)
and its deployment path are located should remain
free from any obstructions.
• Your vehicle is equipped with SABICs. 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 perma-
nent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the
vehicle for any reason.
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.
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.

WARNING!(Continued)
•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.
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. In
the event the vehicle experiences a rollover or near rollover
event, and deployment of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the seat belt
pretensioners on both sides of the vehicle.
