used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.

WARNING!(Continued)
•Never place anything on or near the vehicle’s oper-
able 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 aftermarket 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 electri-
cal system or modify the antennas on your vehicle. IF
YOUR VEHICLE LOSES BATTERY POWER FOR
ANY REASON (INCLUDING DURING OR AFTER
AN ACCIDENT), THE UCONNECT FEATURES,
APPS AND SERVICES, AMONG OTHERS, WILL
NOT OPERATE.
(Continued)
WARNING! (Continued)
•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.
SOS Call System Limitations
Vehicles sold in Mexico DO NOThave 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 de-
tected, and at the beginning of each ignition cycle:
• The overhead console light located between the ASSIST
and SOS buttons will continuously be illuminated red.
• The Device Screen will display the following message:
“Vehicle device requires service. Please contact your
dealer.”
• An In-Vehicle Audio message will state “Vehicle device
requires service. Please contact your dealer.”

WARNING!
•Ignoring the overhead console light could mean you
will not have SOS Call services. If the overhead
console 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.
