Automatic SOS — If Equipped
Automatic SOS is a hands-free safety service that
can immediately connect you with help in the event
that your vehicle’s airbags deploy. After an
accident, a live agent will contact you through the
Uconnect system and alert emergency services.
NOTE:An active SiriusXM Guardian™ subscription is
required for this feature to function.
After a crash where the airbags deploy:

1. Automatic SOS will initiate a call with an agent.

2. An agent will receive the call and confirm the location of the emergency.
3. If needed, the agent will request the assistance of emergency services.
4. First responders will arrive on scene. The agent will remain on the call until emergency
services arrive.
NOTE:
Agents are available 24/7 to assist you in the
case of an emergency.
On your behalf, agents are able to notify family
members about the collision.
Agents can brief first responders of the situation
before they arrive on scene.
WARNING!
Never place anything on or near the vehicle’s
LTE (voice/data) or 4G (data) and GPS
antennas. You could prevent LTE (voice/data)
or 4G (data) and GPS signal reception, which
can prevent your vehicle from placing an
emergency call.
Do not add any aftermarket electrical equip -
ment 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 equip -
ment (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 POWER FOR
ANY REASON (INCLUDING DURING OR AFTER
AN ACCIDENT), NEITHER THE VEHICLE
BRANDED APPS NOR THE SIRIUSXM
GUARDIAN™ CONNECTED SERVICES WILL
OPERATE.
The Occupant Restraint Controller (ORC) turns
on the Air Bag Warning Light on the instru -
ment panel if a malfunction in any part of the
air bag system is detected. If the Air Bag
Warning Light is illuminated, the air bag
system may not be working properly and the
SOS Call system may not be able to send a
signal to the SiriusXM Guardian™ Customer
Care center. If the Air Bag Warning Light is illu -
minated, have an authorized dealer service
your vehicle immediately.
Ignoring the Rearview Mirror Light could mean
you will not have SOS Call services if needed.
If the Rearview Mirror Light is illuminated,
have an authorized dealer service the SOS
Call system immediately.
If anyone in the vehicle could be in danger
(e.g., fire or smoke is visible, dangerous road
conditions or location), do not wait for voice
contact from a SiriusXM Guardian™ Customer
Care agent. All occupants should exit the
vehicle immediately and move to a safe loca -
tion.
Failure to perform scheduled maintenance
and regular inspection of your vehicle may
result in vehicle damage, accident or injury.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic oil
change indicator system. The oil change indicator
system will remind you that it is time to take your
vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent short-trips,
trailer tow, or extremely hot or cold ambient
temperatures will influence when the “Change Oil”
or “Oil Change Required” message is displayed.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
On vehicles equipped with an instrument cluster
display, “Oil Change Required” will be displayed
and a single chime will sound, indicating that an oil
change is necessary. On vehicles not equipped with an instrument
cluster display, “Change Oil” will flash in the
instrument cluster odometer and a single chime
will sound, indicating that an oil change is
necessary.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. To reset the system follow the steps
described Ú
page 122.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for fleet
customers. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire pressures and look for unusual
wear or damage, rotate at the first sign of irreg
-
ular wear.
Check the fluid levels of the coolant reservoir,

Engine Oil Filter Replacement
Residual oil in the housing may spill from the
housing when the new filter is installed if the
residual oil is not either removed from the housing
or enough time has not elapsed to allow the oil to
drain back into the engine. When servicing the oil
filter on this engine, open the filter cap
approximately six turns until the cap o-ring is
visible and stop. Wait five minutes with the cap in
this position to allow dirty engine oil to drain back
into the engine. After five minutes, the cap and
filter assembly can be removed and discarded. Once A Month Or Before A Long Trip:Check engine oil level
Check windshield washer fluid level
Check the tire pressures and look for unusual
wear or damage
Check the fluid levels of the coolant reservoir,

404SERVICING AND MAINTENANCE
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.
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 pres
-
sures 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 replacement
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
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends using tires equivalent to the originals
in size, quality, and performance when
replacement is needed Ú page 404. Refer to the
Tire And Loading Information Placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart found in the “Tire Safety
Information” section of this manual for more
information relating to the Load Index and Speed
Symbol of a tire Ú page 397.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels.
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.
1 — Tread Wear Indicators
WARNING!
Tires and the spare tire should be replaced after
six years, regardless of the remaining tread.
Failure to follow this warning can result in
sudden tire failure. You could lose control and
have a collision resulting in serious injury or
death.

TECHNICAL SPECIFICATIONS421
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
FUEL REQUIREMENTS – DIESEL ENGINE
Federal law requires that you must fuel this vehicle
with Ultra Low Sulfur Highway Diesel fuel (15 ppm
Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur
maximum) to avoid damage to the emissions
control system.
Use good quality diesel fuel from a reputable
supplier in your vehicle. For most year-round
service, Number 2 diesel fuel meeting ASTM
(formerly known as the American Society for
Testing and Materials) specification D-975 Grade
S15 will provide good performance. If the vehicle is exposed to extreme cold (below 20°F or -7°C), or
is required to operate at colder-than-normal
conditions for prolonged periods, use climatized
Number 2 diesel fuel or dilute the Number 2 diesel
fuel with 50% Number 1 diesel fuel. This will
provide better protection from fuel gelling or
wax-plugging of the fuel filters.
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the
accumulated water from the fuel/water separator
using the fuel/water separator drain provided on
the fuel filter housing. If you buy good quality fuel
and follow the listed cold weather
recommendations, fuel conditioners should not be
required in your vehicle. If available in your area, a
high cetane “premium” diesel fuel may offer
improved cold-starting and warm-up performance.
DIESEL FUEL SPECIFICATIONS
This diesel engine has been developed to take
advantage of the high energy content and
generally lower cost Number 2 Ultra Low Sulfur
diesel fuel or Number 2 Ultra Low Sulfur climatized
diesel fuels.
NOTE:
If you accidentally fill the fuel tank with gasoline
or DEF on your diesel vehicle, do not start the
engine. Damage to the engine and fuel system
could occur. Please call an authorized dealer for
service.
A maximum blend of 5% biodiesel meeting
ASTM specification D-975 may be used with
your diesel engine without any adjustments to
regular service schedules.
Commercially available fuel additives are not
necessary for the proper operation of your
diesel engine.
Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic conditions
(-10°F or -23°C) exist.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom
-
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of The manufac -
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain
conditions and hazardous or explosive when
mixed with diesel fuel.
CAUTION!
If the Water in Fuel Indicator Light remains on,
DO NOT START engine before you drain the water
from the fuel filter(s) to avoid engine damage
