How It Works

1. Push the SOS Call button; the indicator light will turn green indicating a call has
been placed.

NOTE:
In case the SOS Call button is accidentally
pushed, there is a 10-second delay before
the SOS call is placed. The system will
verbally alert you that a call is about to be
made. To cancel the SOS Call connection,
push the SOS Call button on the rearview
mirror or press the Cancel button on the
touchscreen within 10 seconds.
During an SOS Call, the Bluetooth® paired
phone is disconnected so incoming or
outgoing calls will go through your mobile
device versus the hands-free system which is
not available due to the SOS Call.
2. Once a connection between the vehicle and a SiriusXM Guardian™ Customer Care agent is
made, the agent will stay on the line with you.
NOTE:
Calls between the vehicle occupants and the
SiriusXM Guardian™ Customer Care center may
be recorded or monitored for quality assurance purposes. Through your enrollment in and use
of the SiriusXM Guardian™ services, you
consent to being recorded.
SOS Call System Limitations
Vehicles that have been purchased in the US
and that travel into Mexico and Canada may
have limited services. In particular, responses
to SOS calls or other emergency services may
be unavailable or very limited. Vehicles
purchased outside the United States and
Canada are unable to receive SiriusXM
Guardian™ services.
If the SOS Call system detects a malfunction,
any of the following may occur at the time the
malfunction is detected:
The light will continuously be illuminated red.
The screen will display the following message
“Vehicle phone requires service. Please
contact your dealer.”
An in-vehicle audio message will state
“Vehicle phone requires service. Please
contact your dealer.”
Even if the SOS Call system is fully functional,
factors beyond FCA US LLC’s control may
prevent or stop SOS Call system operation. These include, but are not limited to, the
following factors:
The ignition key is in OFF position.
The vehicle’s electrical systems are not
intact.
The vehicle battery loses power or becomes
disconnected during a vehicle crash.
The SOS Call system software and/or hard
-
ware is damaged during a vehicle crash.
LTE (voice/data) or 3G or 4G (data) coverage
and/or GPS signals are unavailable or
obstructed.
Network congestion.
Weather conditions.
Buildings, structures, geographic terrain, or
tunnels.
If your vehicle loses battery power for any
reason (including during or after an accident)
the SOS Call System, among other vehicle
systems, will not operate.

ENGINE OIL — GAS ENGINE
Engine Oil Selection — Gasoline Engine
For best performance and maximum protection
under all types of operating conditions, FCA only
recommends engine oils that are API Certified
and meet the requirements of FCA Material
Standard MS-6395.
NOTE:
Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approxi -
mately 30 seconds. This is normal and will not
harm the engine. This characteristic can be
caused by short drive cycles. For example, if the
vehicle is started then shut off after driving a
short distance. Upon restarting, you may experi -
ence a ticking sound. Other causes could be if
the vehicle is unused for an extended period of
time, incorrect oil, extended oil changes or
extended idling. If the engine continues to tick
or if the Malfunction Indicator Light (MIL) comes
on, see the nearest authorized dealer.
Engine Oil Selection — Diesel Engine
For best performance and maximum protection
under all types of operating conditions, FCA
recommends engine oils that meet the
requirements of FCA Material Standard MS-12991, and that are API SN certified and
meet the requirements of FCA LLC.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends API
Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
Synthetic Engine Oils
You may use synthetic engine oils provided the
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Materials Added To Engine Oil
FCA strongly recommends against the addition
of any additives (other than leak detection dyes)
to the engine oil. Engine oil is an engineered
product and its performance may be impaired
by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used
engine oil and oil filters from your vehicle. Used
oil and oil filters, indiscriminately discarded, can
present a problem to the environment. Contact
an authorized dealer, service station or
governmental agency for advice on how and
where used oil and oil filters can be safely
discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a
new filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be
used for replacement. The quality of
replacement filters varies considerably. Only
high quality Mopar certified filters should be
used.
CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New
Vehicle Limited Warranty.

DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
The fuel/water separator filter housing is
located inside the frame rail, behind the left
front wheel. The best access to this water drain
valve is from under the vehicle. If water is detected in the water separator while
the engine is running, or while the ignition
switch is in the ON/RUN position, the “Water In
Fuel Indicator Light” will illuminate and an
audible chime will be heard. At this point, you
should stop the engine and drain the water from
the filter housing.

Fuel Filter Assembly
If the “Water In Fuel Indicator Light” comes on
and a single chime is heard while you are
driving, or with the ignition in the ON position,
there may be a problem with your water
separator wiring or sensor. See an authorized
dealer for service.
Upon proper draining of the water from the fuel
filter, the “Water In Fuel Indicator Light” will
remain illuminated for approximately 10
seconds. If the water was drained while the
engine was running, the “Water In Fuel Indicator
Light” may remain on for approximately three
minutes.
NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi
-
ronment. Contact an authorized dealer, service
station, or government agency for advice on
recycling programs and for where used fluids
and filters can be properly disposed of in your
area.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.

limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a Run Flat tire is changed
after driving with underinflated tire condition,
please replace the TPM sensor as it is not
designed to be reused when driven under Run
Flat mode 14 psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the
vehicle on a flat tire condition.
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.
For more information Úpage 327.
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.
For further information Ú page 391.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.

Tire Tread
These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an
inch (1.6 mm). When the tread is worn to the
tread wear indicators, the tire should be
replaced.
For further information Ú
page 453.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replace -
ment
Distance driven
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is
highly recommended
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin your
vehicle's wheels faster than 30 mph (48 km/h)
for more than 30 seconds continuously when
you are stuck, and do not let anyone near a
spinning wheel, no matter what the speed.
