Maintaining Your Air Bag System
Event Data Recorder (EDR)
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like
situations, such as an air bag deployment or hitting
a road obstacle, data that will assist in
understanding how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such data
as:
How various systems in your vehicle were oper
-
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
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 compo -
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/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 acciden -
tally or may not function properly if modifica -
tions are made. Take your vehicle to an
authorized dealer for any air bag system
service. If your seat, including your trim cover
and cushion, needs to be serviced in any way
(including removal or loosening/tightening of
seat attachment bolts), take the vehicle to an
authorized dealer. Only manufacturer
approved seat accessories may be used. If it is
necessary to modify the air bag system for
persons with disabilities, contact an autho -
rized dealer.

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

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.

348SERVICING AND MAINTENANCE
Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032. When adding
engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT that meets the requirements of the
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine
coolant that meets the requirements of the
manufacturer Material Standard MS.90032
and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below
−34°F (−37°C) are anticipated. Please contact
an authorized dealer for assistance.
Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant solution. The use of lower quality water
will reduce the amount of corrosion protection
in the engine cooling system.
NOTE:
It is the owner's responsibility to maintain the
proper level of protection against freezing
according to the temperatures occurring in the
area where the vehicle is operated.
Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to mini -
mize spillage onto the top of the engine. Any excess fluid that is spilled onto the top of the
engine should be removed using compressed
air or an absorbent cloth.
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system, please contact a local authorized
dealer.
Mixing engine coolant types is not recom
-
mended and can result in cooling system
damage. If HOAT and OAT coolant are mixed in
an emergency, have an authorized dealer drain,
flush, and refill with OAT coolant (conforming to
MS.90032) as soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank (if
equipped).
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is
a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent
ingestion by animals or children, do not store
ethylene glycol-based coolant in open containers
or allow it to remain in puddles on the ground,
clean up any ground spills immediately. If ingested
by a child or pet, seek emergency assistance
immediately.
Coolant Level
The coolant bottle provides a quick visual method
for determining that the coolant level is adequate.
With the engine off and cold, the level of the engine
WARNING!
Do not open a hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated engine.
Heat causes pressure to build up in the
cooling system. To prevent scalding or injury,
do not remove the pressure cap while the
system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
