2011 JEEP WRANGLER lock

Energy Management Feature
This vehicle has a safety belt system with an Energy
Management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
accident.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.
WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly Automatic Locking Re-
tractor (ALR) feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in accidents.
Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of an
accident. These devices may improve the performance of
the seat belt by assuring that the belt is tight about the
occupant early in an accident. 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.
56 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Advanced Front Air Bags 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 Air Bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions.
The Advanced 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, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.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 crashes,
and also are needed to help keep you in position, away
from an inflating air bag.
The ORC also monitors the readiness of the electronic
parts of the air bag system whenever the ignition switch
is in the START or ON/RUN positions. If the key is in the
LOCK position, in the ACC position, or not in the
ignition, the air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.

Front And Side Impact Sensors
In front and side impacts, front and side impact sensors
can aid the ORC in determining the appropriate response
to certain impact events.
Enhanced Accident Response System
In the event of an impact causing air bag 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 Advanced 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 nylon air bag material may sometimes cause
abrasions and/or skin reddening to the driver and
front passenger 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.

Air Bag Warning Light
You will want to have the air bags ready to
inflate for your protection in a collision. The
Air Bag Warning Light monitors the internal
circuits and interconnecting wiring associated
with air bag system electrical components. While the air
bag system is designed to be maintenance free. If any of
the following occurs, have an authorized dealer service
the air bag system immediately.
•The Air Bag Warning Light does not come on during
the four to eight seconds when the ignition switch is
first turned to 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. NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags 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 air bag fuses. See your authorized dealer if the
fuse is good.
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 per-
formed. 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;

WARNING!
•Rearward-facing child seats must never be used in
the front seat of a vehicle with the front passenger
air bag unless the air bag is turned off. An air bag
deployment could cause severe injury or death to
infants in this position.
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety Standards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•The seat belts in the passenger seating positions are
equipped with either an Automatic Locking Retractor
(ALR) or a cinching latch plate or both. Both types of
seat belts are designed to keep the lap portion of the
seat belt tight around the child restraint so that it is not
necessary to use a locking clip. The ALR will make a
ratcheting noise if you extract the entire belt from the
2

retractor and then allow the belt to retract into the
retractor. For additional information on ALR, refer to
“Automatic Locking Mode”.
•In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.
•If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
WARNING!
When your child restraint is not in use, secure it in
the vehicle with the seat belt or remove it from the
vehicle. Do not leave it loose in the vehicle. In a
sudden stop or accident, it could strike the occupants
or seatbacks and cause serious personal injury.
Older Children And Child Restraints
Children who weigh more than 20 lbs (9 kg) and who are
older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible child
seats used in the forward-facing direction are for children
who weigh 20 to 40 lbs (9 to 18 kg), and who are older
than one year. These child seats are also held in the
vehicle by the lap/shoulder belt or the LATCH child
restraint anchorage system. Refer to “Lower Anchors and
Tether for CHildren (LATCH)”.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

a hook for attachment to the tether strap anchorage, and
a means for adjusting the tension of the strap.
You will first loosen the child seat adjusters on the lower
straps and on the tether strap so that you can more easily
attach the hooks or connectors to the vehicle anchorages.
Next, attach the lower hooks or connectors over the top
of the anchorage bars, pushing aside the seat cover
material. Then, locate the tether anchorage directly be-
hind the seat where you are placing the child restraint
and attach the tether strap to the anchorage, being careful
to route the tether strap to provide the most direct path
between the anchor and the child restraint. Finally,
tighten all three straps as you push the child restraint
rearward and downward into the seat, removing slack in
the straps according to the child restraint manufacturer’s
instructions.WARNING!
Improper installation of a child restraint to the
LATCH anchorages can lead to failure of an infant or
child restraint. The child could be badly injured or
killed. Follow the manufacturer’s directions exactly
when installing an infant or child restraint.
Installing Child Restraints Using The Vehicle Seat
Belt
The seat belts in the passenger seating positions are
equipped with an Automatic Locking Retractor to secure
a Child Restraint System (CRS). These types of seat belts
are designed to keep the lap portion of the seat belt tight
around the child restraint so that it is not necessary to use
a locking clip. The ALR will make a ratcheting noise if
you extract the entire belt from the retractor and then
allow the belt to retract into the retractor. For additional
information on ALR, refer to “Automatic Locking Mode”

1. To install a child restraint with ALR, first, pull enough
of the seat belt webbing from the retractor to route it
through the belt path of the child restraint. Slide the latch
plate into the buckle until you hear a “click.” Next,
extract all the seat belt webbing out of the retractor and
then allow the belt to retract into the retractor. As the belt
retracts, you will hear a ratcheting sound. This indicates
the safety belt is now in the Automatic Locking mode.
2. Finally, pull on any excess webbing to tighten the lap
portion around the child restraint. Any seat belt system
will loosen with time, so check the belt occasionally, and
pull it tight if necessary.
