JEEP GRAND CHEROKEE 2017 WK2 / 4.G Owners Manual

Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted lap/
shoulder belt.
1. Position the latch plate as close as possible to the anchorpoint.
2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the seat belt webbing 180 degrees
to create a fold that begins immediately above the latch
plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing must enter the slot at the top of the
latch plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat belt is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and front passenger seats, the top of the
shoulder belt can be adjusted upward or downward to
position the seat belt away from your neck. Push or
squeeze the anchorage button to release the anchorage, and
move it up or down to the position that serves you best.

SAFETY 219

As a guide, if you are shorter than average, you will prefer
the shoulder belt anchorage in a lower position, and if you
are taller than average, you will prefer the shoulder belt
anchorage in a higher position. After you release the
anchorage button, try to move it up or down to make sure
that it is locked in position.
NOTE:
The adjustable upper shoulder belt anchorage is
equipped with an Easy Up feature. This feature allows the
shoulder belt anchorage to be adjusted in the upward
position without pushing or squeezing the release button. To
verify the shoulder belt anchorage is latched, pull downward
on the shoulder belt anchorage until it is locked into position.
WARNING!
• Wearing your seat belt incorrectly could make your
injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.
• Position the shoulder belt across the shoulder and
chest with minimal, if any slack so that it is comfort-
able and not resting on your neck. The retractor will
withdraw any slack in the shoulder belt.
(Continued)
WARNING! (Continued)
•Misadjustment of the seat belt could reduce the
effectiveness of the safety belt in a crash.
Seat Belt Extender
If a seat belt is not long enough to fit properly, even when
the webbing is fully extended and the adjustable upper
shoulder belt anchorage (if equipped) is in its lowest
position, your authorized dealer can provide you with a
Seat Belt Extender. The Seat Belt Extender should be used
only if the existing seat belt is not long enough. When the
Seat Belt Extender is not required for a different occupant,
it must be removed.
WARNING!
• ONLY use a Seat Belt Extender if it is physically
required in order to properly fit the original seat belt
system. DO NOT USE the Seat Belt Extender if,
when worn, the distance between the front edge of
the Seat Belt Extender buckle and the center of the
occupant’s body is LESS than 6 inches.
(Continued)
220 SAFETY

WARNING!(Continued)
•Using a Seat Belt Extender when not needed can
increase the risk of serious injury or death in a
collision. Only use the Seat Belt Extender when the
lap belt is not long enough and only use in the
recommended seating positions. Remove and store
the Seat Belt Extender when not needed.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants including preg-
nant 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 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. The 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.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 a
click.
Automatic Locking Retractor (ALR) Locations
222 SAFETY

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) lock-
ing 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.

SAFETY 223

Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable components,
and vehicles with this equipment cannot be readily iden-
tified by any markings, only through visual inspection of
the head restraint. The head restraint will be split in two
halves, with the front half being soft foam and trim, the
back half being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) determines
whether the severity or type of rear impact will require the
Active Head Restraints (AHR) to deploy. If a rear impact
requires deployment, both the driver and front passenger
seat AHRs will be deployed.
When AHRs deploy during a rear impact, the front half of
the head restraint extends forward to minimize the gap
between the back of the occupant’s head and the AHR. This
system is designed to help prevent or reduce the extent of
injuries to the driver and front passenger in certain types of
rear impacts.NOTE:
The Active Head Restraints (AHR) may or may not
deploy in the event of a front or side impact. However, if
during a front impact, a secondary rear impact occurs, the
AHR may deploy based on the severity and type of the
impact.
Active Head Restraint (AHR) Components:
Active Head Restraint (AHR) Components
1 — Head Restraint Front Half (Soft Foam and Trim)
2 — Head Restraint Back Half (Decorative Plastic Rear Cover)
3 — Head Restraint Guide Tubes
4 — Seatback
224 SAFETY

WARNING!
•All occupants, including the driver, should not oper-
ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in
order to minimize the risk of neck injury in the event
of a collision.
• Do not place items over the top of the Active Head
Restraint, such as coats, seat covers or portable DVD
players. These items may interfere with the opera-
tion of the Active Head Restraint in the event of a
collision and could result in serious injury or death.
• Active Head Restraints may be deployed if they are
struck by an object such as a hand, foot or loose
cargo. To avoid accidental deployment of the Active
Head Restraint ensure that all cargo is secured, as
loose cargo could contact the Active Head Restraint
during sudden stops. Failure to follow this warning
could cause personal injury if the Active Head Re-
straint is deployed.
NOTE: For more information on properly adjusting and
positioning the head restraint, refer to “Active Head Re-
straints” in “Getting To Know Your Vehicle.” Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered during a colli-
sion, the front half of the head restraint will be extended
forward and separated from the rear half of the head
restraint (see image). Do not drive your vehicle after the
AHRs have deployed. The head restraint must be reset into
the original position to best protect the occupant for all
types of collisions. An authorized FCA US LLC dealer must
reset the AHRs on the driver ’s and front passenger ’s seat
before driving. Personally attempting to reset the AHRs
may result in damage to the AHRs that could impair their
function.
WARNING!
Deployed AHRs are not able to best protect you in all
types of collisions. Have deployed AHRs reset by an
authorized dealer immediately.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask your autho-
rized dealer.

Air Bag Warning Light
The ORC monitors the readiness of the electronic
parts of the air bag system whenever the ignition
switch is in the START or ON/RUN position. If
the ignition switch is in the OFF position or in the
ACC position, 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 bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is first in the
ON/RUN position. After the self-check, the Air Bag Warn-
ing Light will turn off. If the ORC detects a malfunction in
any part of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A single chime
will sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air
226 SAFETY

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 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.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condition
the air bags may not be ready to inflate for your protection.
Have an authorized dealer service the air bag system
immediately.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on

Front Air Bags
This vehicle has front air bags and lap/shoulder belts for
both the driver and front passenger. The front air bags are a
supplement 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 AIR-
BAG” or “AIRBAG” are embossed on the air bag covers.
WARNING!
•Being too close to the steering wheel or instrument
panel during 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 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.
