Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
Supplemental Driver And Front Passenger
Knee Air Bags
This vehicle is equipped with a Supplemental
Driver Knee Air Bag mounted in the instrument
panel below the steering column and a
Supplemental Passenger Knee Air Bag mounted in
the instrument panel below the glove
compartment. The Supplemental Knee Air Bags
provide enhanced protection during a frontal
impact by working together with the seat belts,
pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs). Supplemental Seat-Mounted Side Air Bags (SABs)
are located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
injury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label

When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag. Supplemental Side Air Bag Inflatable Curtains
(SABICs)
This vehicle is equipped with Supplemental Side
Air Bag Inflatable Curtains (SABICs).
Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

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.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags; the
performance could be adversely affected and/or
objects could be pushed into you, causing
serious injury.

SOS Call System Limitations
Vehicles sold in Mexico
DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in Mexico
may not answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any
of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console lights located within the
ASSIST and SOS buttons will continuously illumi -
nate red.
The Device Screen will display the following
message “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state “Vehicle
device requires service. Please contact an
authorized dealer.”
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:

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
disconnected during a vehicle crash
LTE (voice/data) or 4G (data) network and/or
Global Positioning Satellite signals are unavail
-
able or obstructed

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
Never place anything on or near the vehicle’s
operable network and GPS antennas. You
could prevent operable network and GPS
signal reception, which can prevent your
vehicle from placing an emergency call. An
operable network and GPS signal reception is
required for the SOS Call system to function
properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add after -
market electrical equipment to the vehicle’s
electrical system. This may prevent your
vehicle from sending a signal to initiate an
emergency call. To avoid interference that can
cause the SOS Call system to fail, never add
aftermarket equipment (e.g., two-way mobile
radio, CB radio, data recorder, etc.) to your
vehicle’s electrical system or modify the
antennas on your vehicle. IF YOUR VEHICLE
LOSES BATTERY POWER FOR ANY REASON
(INCLUDING DURING OR AFTER AN ACCI -
DENT), THE JEEP® CONNECT FEATURES,
APPS AND SERVICES, AMONG OTHERS, WILL
NOT OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to fail
when you need it. You could be injured if the
air bag system is not there to help protect you.
WARNING!
WARNING!
Ignoring the overhead console light could
mean you will not have SOS Call services. If
the overhead console light is illuminated, have
an 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 illumi -
nated, have an authorized dealer service the
Occupant Restraint Control system immediately.

Cleaning Plastic Instrument Cluster
Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When cleaning
the lenses, care must be taken to avoid scratching
the plastic.
Clean with a wet soft cloth. A mild soap solution
may be used, but do not use high alcohol content
or abrasive cleaners. If soap is used, wipe clean
with a clean damp cloth. Dry with a soft cloth.
LEATHER SURFACES
Mopar® Total Clean is specifically recommended
for leather upholstery.
The leather upholstery can be best preserved by
regular cleaning with a damp soft cloth. Small

leather upholstery with any liquid. Please do not
use polishes, oils, cleaning fluids, solvents,
detergents, or ammonia-based cleaners to clean
your leather upholstery.
NOTE:If equipped with light colored leather, it tends to
show any foreign material, dirt, and fabric dye
transfer more so than darker colors. The leather is
designed for easy cleaning, and the manufacturer
recommends Mopar® total care leather cleaner
applied on a cloth to clean the leather seats as
needed.GLASS SURFACES
All glass surfaces should be cleaned on a regular
basis with Mopar® Glass Cleaner, or any
commercial household-type glass cleaner. Never
use an abrasive type cleaner. Use caution when
cleaning the inside rear window equipped with
electric defrosters or windows equipped with radio
antennas. Do not use scrapers or other sharp
instruments that may scratch the elements.
