Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional protection by supplementing the seat
belts. Front air bags are not expected to
reduce the risk of injury in rear, side, or roll -
over collisions. The front air bags will not
deploy in all frontal collisions, including
some that may produce substantial 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.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indica -
tors 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 passenger 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.
Passenger Air Bag Disable Feature — If
Equipped
This system allows the driver to DISABLE
(OFF) the Passenger Advanced Front Air Bag
if a child restraint
must be installed in the
front seat. Only DISABLE (OFF) the
Passenger Advanced Front Air Bag if it is
absolutely necessary to install a child
restraint in the front seat. Children 12 years
or younger should ride properly buckled up in
a rear seat, if available. According to crash
statistics, children are safer when properly
restrained in the rear seats rather than in the
front. (Refer to “Child Restraints” in this
section for further information.)
WARNING!
A DISABLED (OFF) Passenger Advanced
Front Air Bag is deactivated and will not
deploy in a collision.
A DISABLED (OFF) Passenger Advanced
Front Air Bag will not provide a front
passenger additional protection by
supplementing the seat belts.
Do not install a child restraint in the
front seat unless the Passenger Air Bag
DISABLE (OFF) Indicator light on the
center stack is illuminated to show that
the Passenger Advanced Front Air Bag is
DISABLED (OFF).
In a collision, you and your passengers
can suffer much greater injuries if you
are not properly buckled up. You can
strike the interior of your vehicle or other
passengers, or you can be thrown out of
the vehicle. Always be sure you and
others in your vehicle are buckled up
properly.

Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant
Restraint Controller (ORC) determines
whether the deployment of the Side Air Bags
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 Side Air Bags on the impact side
of the vehicle during impacts that require
Side Air Bag occupant protection. In side
impacts, the Side Air Bags deploy inde-
pendently; a left side impact deploys the left
Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. 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 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.
Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes. NOTE:
Air bag covers may not be obvious in the inte
-
rior trim, but they will open during air bag
deployment.
Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events
(if equipped with rollover sensing). The
Occupant Restraint Controller (ORC) deter -
mines whether deployment in a particular
rollover event is appropriate, based on the
severity and type of collision. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags and seat belt
pretensioners should have deployed. WARNING!
Occupants, including children, who are
up against or very close to Side Air Bags
can be seriously injured or killed. Occu -
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
inflate, even if they are in an infant or
child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also
help keep you in position, away from an
inflating Side Air Bag. To get the best
protection from the Side Air Bags, occu -
pants must wear their seat belts properly
and sit upright with their backs against
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
WARNING!
Side Air Bags need room to inflate. Do
not lean against the door or window. Sit
upright in the center of the seat.
Being too close to the Side Air Bags
during deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a colli -
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
WARNING! (Continued)

SAFETY
110
The Side Air Bags and seat belt preten-
sioners 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 deploy the Side Air Bags
and seat belt pretensioners on both sides of
the vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu -
pants through side windows in certain roll -
over or side impact events.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon -
necting wiring associated with electrical Air
Bag System Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
If A Deployment Occurs
The 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 air bag material may sometimes cause
abrasions and/or skin reddening to the
occupants as the air bags deploy and
unfold. The abrasions are similar to fric-
tion rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with chem -
icals. They are not permanent and
normally heal quickly. However, if you haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that
generates the non-toxic gas used for air
bag inflation. These airborne particles may
irritate the skin, eyes, nose, or throat. If
you have skin or eye irritation, rinse the
area with cool water. For nose or throat irri
-
tation, move to fresh air. If the irritation
continues, see your doctor. If these parti -
cles settle on your clothing, follow the
garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in
another collision. Have the air bags, seat
belt pretensioners, and the seat belt
retractor assemblies replaced by an
authorized dealer immediately. Also, have
the Occupant Restraint Controller System
serviced as well.

STARTING AND OPERATING
152
ACC will allow you to keep cruise control
engaged in light to moderate traffic condi-
tions without the constant need to reset your
cruise control. ACC utilizes a radar sensor
and a forward facing camera designed to
detect a vehicle directly ahead of you.
NOTE:
If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed set
speed.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceler -
ation (not to exceed the original set speed)
automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.
To Activate/Deactivate
Push and release the Adaptive Cruise Control
(ACC) on/off button. The ACC menu in the
instrument cluster display will read “ACC
Ready.”
To turn the system off, push and release the
Adaptive Cruise Control (ACC) on/off button
again. At this time, the system will turn off
and the instrument cluster display will read
“Adaptive Cruise Control (ACC) Off.”
To Set A Desired ACC Speed
When the vehicle reaches the speed desired,
push the SET (+) button or the SET (-) button
and release. The instrument cluster display
will show the set speed.
If the system is set when the vehicle speed is
below 19 mph (30 km/h), the set speed shall be defaulted to 19 mph (30 km/h). If the
system is set when the vehicle speed is
above 19 mph (30 km/h), the set speed shall
be the current speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary
vehicle in front of your vehicle in close prox -
imity. Remove your foot from the accelerator pedal.
If you do not, the vehicle may continue to
accelerate beyond the set speed. If this
occurs:
The message “DRIVER OVERRIDE” will
display in the instrument cluster display.
The system will not be controlling the
distance between your vehicle and the
vehicle ahead. The vehicle speed will only
be determined by the position of the
accelerator pedal.
To Resume
If there is a set speed in the memory, push
the RES button and then remove your foot
from the accelerator pedal. The instrument
cluster display will show the last set speed.
WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous.
You could accidentally set the system or
cause it to go faster than you want. You
could lose control and have a collision.
Always leave the system off when you are
not using it.
WARNING!
The Resume function should only be used
if traffic and road conditions permit.
Resuming a set speed that is too high or
too low for prevailing traffic and road
conditions could cause the vehicle to
accelerate or decelerate too sharply for
safe operation. Failure to follow these
warnings can result in a collision and
death or serious personal injury.
2020_JEEP_M6_UG_UK.book Page 152

STARTING AND OPERATING
154
If equipped with a automatic transmis-
sion, The ACC system decelerates the
vehicle to a full stop when following a
target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill,
after two seconds the driver will either
have to push the RES (resume) button, or
apply the accelerator pedal to reengage
the ACC to the existing set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may
occur while climbing uphill or descending
downhill. This is normal operation and
necessary to maintain set speed. When
driving uphill and downhill, the ACC
system will cancel if the braking tempera-
ture exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can
be set by varying the distance setting
between four bars (longest), three bars
(long), two bars (medium) and one bar
(short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting will show in the instrument cluster
display.To decrease the distance setting, push the
Distance Button and release. Each time the
button is pushed, the distance setting
decreases by one bar (shorter). Once the
shortest setting is reached, if the button is
pushed again it will be set to the longest
setting available.
PARKSENSE REAR PARK
ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of
the distance between the rear fascia and a
detected obstacle when backing up (e.g.
during a parking maneuver). Refer to “Park
-
Sense System Usage Precautions” for limita -
tions of this system and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
ParkSense can be active only when the gear
selector is in REVERSE. The system will
remain active until the vehicle speed is
increased to approximately 7 mph (11 km/h)
or above. While in REVERSE and above the
system's operating speed, a warning will
appear in the instrument cluster display indi -
cating the vehicle speed is too fast. The system will become active again if the
vehicle speed is decreased to speeds less
than approximately 6 mph (9 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction,
depending on the location, type and orienta
-
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be
displayed if “Sound and Display” is selected
from the Customer - Programmable Features
section of the Uconnect System. Refer to
"Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
The ParkSense Warning screen is located
within the instrument cluster display. It
provides visual warnings to indicate the
distance between the rear fascia/bumper and
the detected obstacle. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” in the Owner’s Manual for
further information.

Enabling And Disabling ParkSense
ParkSense can be enabled and
disabled with the ParkSense switch,
located on the switch panel below
the Uconnect display.
When the ParkSense switch is pushed to
disable the system, the instrument cluster
display will show the “PARKSENSE OFF”
message for approximately five seconds.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
the Owner’s Manual for further details. When
the gear selector is moved to REVERSE and
the system is disabled, the instrument
cluster display will show the “PARKSENSE
OFF” message for as long as the vehicle is in
REVERSE.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and requires service, the
ParkSense switch LED will blink momen -
tarily, and then the LED will be on.
ParkSense System Usage Precautions
Ensure that the rear bumper is free of
snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Jackhammers, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the instru -
ment cluster display will read “PARK -
SENSE OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
ParkSense, when on, will reduce the
volume of the radio when it is sounding a
tone.
Clean the ParkSense sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to
do so can result in the system not working
properly. The ParkSense system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indica-
tion that an obstacle is behind the fascia/
bumper.
Use the ParkSense switch to turn the
ParkSense system off if objects such as
bicycle carriers, etc. are attached to the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a
close object as a sensor problem, causing
the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be
displayed in the instrument cluster
display.
NOTE:
If any objects are attached to the bumper
within a 6.5 ft (2 m) field of view, they will
interfere and cause false alerts and possibly
blockage.
The operation of the rear sensors is auto-
matically deactivated when the trailer's
electric plug is inserted in the vehicle's
tow hook socket. The rear sensors are
automatically reactivated when the
trailer's cable plug is removed.

STARTING AND OPERATING
156
PARKSENSE FRONT AND
REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the
distance between the rear and/or front fascia
and a detected obstacle when backing up or
moving forward (e.g. during a parking
maneuver).
Refer to “ParkSense System Usage Precau-
tions” in “Starting And Operating” in your Owner’s Manual for limitations of this system
and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
ParkSense is active in all gear selector posi
-
tions (including PARK), as long as the
system is on. The system will remain active
until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above.
While in REVERSE and above the system's
operating speed, a warning will appear in the
instrument cluster display indicating the
vehicle speed is too fast. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
ParkSense Sensors
The six ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction,
depending on the location, type and orienta -
tion of the obstacle.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always
check carefully behind your vehicle, look
behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before
backing up. You are responsible for
safety and must continue to pay atten -
tion to your surroundings. Failure to do
so can result in serious injury or death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected from
the vehicle when the vehicle is not used
for towing. Failure to do so can result in
injury or damage to vehicles or obstacles
because the hitch ball will be much
closer to the obstacle than the rear fascia
when the loudspeaker sounds the contin -
uous tone. Also, the sensors could detect
the ball mount and hitch ball assembly,
depending on its size and shape, giving
a false indication that an obstacle is
behind the vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above
or below the sensors will not be detected
when they are in close proximity.
The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is
detected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.
