2017 JEEP GRAND CHEROKEE steering

When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.
NOTE:
•The minimum speed for FCW activation is 1 mph
(2 km/h).
• The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality. •
It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
• The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range or
ESC Full-Off Mode is active, the FCW system will be
automatically deactivated.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
Turning FCW On Or Off
NOTE: The default status of FCW is “on”, this allows the
system to warn you of a possible collision with the vehicle
in front of you.
FCW Message
204 SAFETY

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

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

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.

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.
230 SAFETY

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.
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 Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated
with electrical Air Bag System Components listed below:

Enhanced Accident Response System
In the event of an impact, 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 following functions:
•Cut off fuel to the engine.
• Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
• Turn on the interior lights, which remain on as long as
the battery has power.
• Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition OFF.
Carefully check the vehicle for fuel leaks in the engine compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine.
Maintaining Your Air Bag System
WARNING!
•
Modifications to any part of the air bag system could
cause it to fail when you need it. You could be
injured if the air bag system is not there to protect
you. Do not modify the components or wiring, in-
cluding adding any kind of badges or stickers to the
steering wheel hub trim cover or the upper right side
of the instrument panel. Do not modify the front
bumper, vehicle body structure, or add aftermarket
side steps or running boards.
• It is dangerous to try to repair any part of the air bag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.
• Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any air
bag system service. If your seat, including your trim

pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.
