JEEP WRANGLER 2016 JK / 3.G Repair Manual

Seat Belts And Pregnant Women
Seat belts must be worn by all occupants including
pregnant women: the risk of injury in the event of an
accident is reduced for the mother and the unborn child
if they are wearing a seat belt.Position the lap belt snug and low below the abdomen
and across the strong bones of the hips. Place the
shoulder belt across the chest and away from the neck.
Never place the shoulder belt behind the back or under
the arm.
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 Re-
straint Controller (ORC). Like the air bags, the preten-
sioners 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
Management 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 “ChildRestraints” section of this manual. The table below
defines the type of feature for each seating position.Two-Door Models
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 clickingsound 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 occupant’s mid-section. Slide the latch
plate into the buckle until you hear a
click.
In Automatic Locking Mode, the shoulder belt is auto-
matically 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 Advanced Front
Air Bag can cause death or serious injury to a child

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 proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase 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.

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 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.
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 bags 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. Al-
ways wear your seat belts even though you have air
bags.
Advanced Front Air Bag Operation
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts. Ad-
vanced Front Air Bags are not expected to reduce the risk
of injury in rear, side, or rollover collisions. The Ad-
vanced Front Air Bags 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 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 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.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 Seat-Mounted Side Air Bags (SABs)
Your vehicle is equipped with Supplemental Seat-
Mounted Side Air Bags (SABs) that are located 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, 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
Supplemental Seat-Mounted Side Air Bag Location

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.
SABs are designed to activate in certain side impacts. The
Occupant Restraint Controller (“ORC”) determines
whether the deployment of the SAB in a particular
impact event is appropriate, based on the severity and
type of collision. The side impact sensors aid the ORC in
determining the appropriate response to impact events. The system is calibrated to deploy the SAB on the impact
side of the vehicle during impacts that require SAB
occupant protection. In side impacts, the SABs deploy
independently; a left side impact deploys the left SAB
only and a right side impact deploys the right side SAB
only. Vehicle damage by itself is not a good indicator of
whether or not SABs should have deployed.
The SABs 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.
SABs are a supplement to the seat belt restraint system.
SABs deploy in less time than it takes to blink your eyes.
Occupants, including children, who are up against or very
close to SABs can be seriously injured or killed. Occupants,
including children, should never lean on or sleep against
the door, side windows, or area where the SABs inflate,
even if they are in an infant or child restraint.
