2017 JEEP GRAND CHEROKEE Owners Manual

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.

SAFETY 225

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated with the electrical Air Bag System Components.
Your vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
•Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Belt Buckle Switch
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

as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (“SRS”), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately.

SAFETY 227

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.
“Base” Front Air Bag And Knee Bolster Locations
1 — Driver And Passenger Front Air Bags
2 — Passenger Knee Impact Bolster
3 — Driver Knee Impact Bolster/Supplemental Knee Air Bag 228 SAFETY

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.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
(Continued)
WARNING! (Continued)
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.
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.
5
SAFETY 229

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.
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.
