WARNING!(Continued)
•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.
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.
222 SAFETY

NOTE:The system will automatically time out and the
ignition will cycle to the OFF mode after 30 minutes of
inactivity if the ignition is left in the ACC or RUN (engine
not running) mode and the transmission is in PARK.
ENGINE START/STOP Button Functions — With Driv-
er ’s Foot OFF The Brake Pedal (In PARK Or NEUTRAL
Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three modes: OFF, ACC, and RUN.
To change the ignition modes without starting the vehicle
and use the accessories, follow these steps:
• Starting with the ignition in the OFF mode,
• Push the ENGINE START/STOP button once to place
the ignition to the ACC mode (instrument cluster will
display “ACC”),
• Push the ENGINE START/STOP button a second time to
place the ignition to the RUN mode (instrument cluster
will display “ON/RUN”),
• Push the ENGINE START/STOP button a third time to
return the ignition to the OFF mode (instrument cluster
will display “OFF”).If Engine Fails To Start

WARNING!
•Ignoring the Rearview Mirror light could mean you
will not have SOS Call services. If the Rearview
Mirror light is illuminated, have your authorized
dealer service the SOS Call system immediately.
• The Occupant Restraint Control module turns on the
air bag Warning Light on the instrument panel if a
malfunction in any part of the system is detected. If
the Air Bag Warning Light is illuminated, have your
authorized dealer service the Occupant Restraint
Control system immediately.
Even if the SOS Call system is fully functional, factors
beyond FCA US LLC’s control may prevent or stop the SOS
Call system operation. These include, but are not limited
to, the following factors:
• Delayed accessories mode is active.
• The ignition is in the OFF position.
• The vehicle’s electrical systems are not intact.
• The SOS Call system software and/or hardware are
damaged during a crash.
• The vehicle battery loses power or becomes discon-
nected during a vehicle crash. •
LTE (voice/data) or 4G (data) network and/or Global
Positioning Satellite signals are unavailable or ob-
structed.
• Equipment malfunction at the SOS operator facility.
• Operator error by the SOS operator.
• LTE (voice/data) or 4G (data) network congestion.
• Weather.
• Buildings, structures, geographic terrain, or tunnels.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Push and hold the lock button on the gear selector.
Then, shift back and forth between DRIVE and REVERSE
while gently pressing the accelerator.
NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for more
than two seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that will
maintain the rocking motion without spinning the wheels
or racing the engine.
NOTE: Push the ESC Off switch (if necessary), to place
the Electronic Stability Control (ESC) system in Partial Off
mode, before rocking the vehicle. Refer to “Electronic
Brake Control” in “Safety” for further information. Once
the vehicle has been freed, push the ESC Offswitch again
to restore ESC Onmode.

Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the vehicle
on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer case
is operable, vehicles with a two-speed transfer case may
be towed (in the forward direction, with ALLwheels on the
ground), IFthe transfer case is in NEUTRAL (N) and the
transmission is in PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed instructions.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and therefore mustbe towed with
all four wheels OFFthe ground.

Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has limited
driving capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more informa-
tion.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer-
gency” for further information.
