SAFETY191
The Air Bag Warning Light in the instrument
panel will turn on whenever the OCS is unable to
classify the front passenger seat status. A
malfunction in the OCS may affect the operation
of the air bag system.
If the Air Bag Warning Light does not come
on, or stays on after you start the vehicle, or it
comes on as you drive, take the vehicle to an
authorized dealer for service immediately.
The passenger seat assembly contains critical
OCS components that may affect the Passenger
Advanced Front Air Bag inflation. In order for the
OCS to properly classify the seated weight of a
front seat passenger, the OCS components
must function as designed. Do not make any
modifications to the front passenger seat components, assembly, or to the seat cover. If
the seat, trim cover, or cushion needs service
for any reason, take the vehicle to an authorized
dealer. Only FCA US LLC approved seat
accessories may be used.
The following requirements must be strictly
followed:
Do not modify the front passenger seat
assembly or components in any way.
Do not use prior or future model year seat
covers or cushions not designated by FCA US
LLC for the specific model being repaired.
Always use the correct seat cover and
cushion specified for the vehicle.
Do not replace the seat cover or cushion with
an aftermarket seat cover or cushion.
Do not add a secondary seat cover or mat.
At no time should any Supplemental
Restraint System (SRS) component or SRS
related component or fastener be modified
or replaced with any part except those which
are approved by FCA US LLC.
Placing an object on the floor under the
front passenger seat may prevent the OCS
from working properly, which may result in
serious injury or death in a collision. Do not
place any objects on the floor under the
front passenger seat.
WARNING!
(Continued)WARNING!
Unapproved modifications or service proce -
dures to the passenger seat assembly, its
related components, seat cover or cushion
may inadvertently change the air bag
deployment in case of a frontal collision.
This could result in death or serious injury
to the front passenger if the vehicle is
involved in a collision. A modified vehicle
may not comply with required Federal
Motor Vehicle Safety Standards (FMVSS)
and/or Canadian Motor Vehicle Safety
Standards (CMVSS).
If it is necessary to modify the air bag
system for persons with disabilities,
contact an authorized dealer.

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
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.

NOTE:
Air bag covers may not be obvious in the interior
trim, but they will open during air bag deploy -
ment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC)
determines whether deployment in a particular
rollover event is appropriate, based on the
severity and type of collision. Vehicle damage by
itself is not a good indicator of whether or not
Side Air Bags and seat belt pretensioners
should have deployed. The Side Air Bags and seat belt pretensioners
will not deploy in all rollover events. The rollover
sensing system determines if a rollover event
may be in progress and whether deployment is
appropriate. In the event the vehicle
experiences a rollover or near rollover event,
and deployment is appropriate, the rollover
sensing system will deploy the side air bags and
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain rollover or side
impact events.
Air Bag System Components

-
tors the internal circuits and interconnecting
wiring associated with electrical Air Bag System
Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your protec -
tion in all collisions. They also help keep
you in position, away from an inflating Side
Air Bag. To get the best protection from the
Side Air Bags, occupants must wear their
seat belts properly and sit upright with their
backs against the seats. Children must be
properly restrained in a child restraint or
booster seat that is appropriate for the size
of the child.
WARNING!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be severely
injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some collisions,
Side Air Bags won’t deploy at all. Always
wear your seat belt even though you have
Side Air Bags.

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for four
to eight seconds as a bulb check when the
ignition switch is first turned to ON/RUN. If the
light is either not on during starting, stays on, or
turns on while driving, have the system
inspected at an authorized dealer as soon as
possible. After the bulb check, this light will
illuminate with a single chime when a fault with
the Air Bag System has been detected. It will stay on until the fault is removed. If the light
comes on intermittently or remains on while
driving, have an authorized dealer service the
vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See an authorized dealer for
service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelerator,
brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat
fasteners so it cannot slip out of position and
interfere with the accelerator, brake or clutch
pedals or impair safe operation of your vehicle
in other ways.
WARNING!
An improperly attached, damaged, folded, or
stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or clutch
pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
ALWAYS securely attach your floor mat
using the floor mat fasteners. DO NOT
install your floor mat upside down or turn
your floor mat over. Lightly pull to confirm
mat is secured using the floor mat
fasteners on a regular basis.
ALWAYS REMOVE THE EXISTING FLOOR
MAT FROM THE VEHICLE before
installing any other floor mat. NEVER install
or stack an additional floor mat on top of an
existing floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that
cannot be properly attached and secured to
your vehicle. If a floor mat needs to be
replaced, only use a FCA approved floor
mat for the specific make, model, and year
of your vehicle.

Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for inter
-
ference, with the vehicle properly parked
with the engine off, fully depress the accel -
erator, the brake, and the clutch pedal (if
present) to check for interference. If your
floor mat interferes with the operation of
any pedal, or is not secure to the floor,
remove the floor mat from the vehicle and
place the floor mat in your trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These objects
could change the position of the floor mat
and may cause interference with the accel -
erator, brake, or clutch pedals.
WARNING! (Continued)
If the vehicle carpet has been removed and
re-installed, always properly attach carpet
to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for inter -
ference with the accelerator, brake, or
clutch pedals then re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.
WARNING! (Continued)

20_RU_OM_EN_US_t.book Page 218

STARTING AND OPERATING225
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contributes
to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental and
should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with
anticipated climate conditions under which
vehicle operations will occur. For the
recommended viscosity and quality grades,
refer to “Dealer Service” in “Servicing And
Maintenance”.
NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera -
tion. This should be considered a normal part of
the break-in and not interpreted as a problem.PARK BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park
Brake System (EPB) that offers simple
operation, and some additional features that
make the park brake more convenient and
useful.
The park brake is primarily intended to prevent
the vehicle from rolling while parked. Before
leaving the vehicle, make sure that the park
brake is applied. Also, be certain to leave the
transmission in PARK.
You can engage the park brake in two ways;
Manually, by applying the park brake switch.
Automatically, by enabling the Auto Park
Brake feature in the customer programmable
features section of the Uconnect Settings. The park brake switch is located in the
integrated center stack.

Electric Park Brake Switch

To apply the park brake manually, push the
switch momentarily. You may hear a slight
whirring sound from the back of the vehicle
while the park brake engages. Once the park
brake is fully engaged, the BRAKE warning lamp
in the instrument cluster and an indicator on
the switch will illuminate. If your foot is on the
brake pedal while you apply the park brake, you
may notice a small amount of brake pedal
movement. The park brake can be applied even
when the ignition switch is OFF, however, it can
only be released when the ignition switch in the
ACC or ON/RUN position.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

226STARTING AND OPERATING
(Continued)
(Continued)
NOTE:
The EPB fault lamp will illuminate if the EPB
switch is held for longer than 180 seconds. The
light will extinguish upon releasing the switch.
If the Auto Park Brake feature is enabled, the
parking brake will automatically engage
whenever the transmission is placed into PARK.
Once the park brake is engaged, the BRAKE
warning lamp in the instrument cluster and the
LED indicator on the switch will illuminate. If
your foot is on the brake pedal, you may notice
a small amount of brake pedal movement while
the parking brake is engaging.
The park brake will release automatically when
the ignition is cycled to the ON/RUN position,
the transmission is in DRIVE or REVERSE, and
the driver seat belt is buckled and an attempt is
made to drive the vehicle away by pressing the
accelerator pedal.
To release the parking brake manually, the
ignition switch must be in the ON/RUN position.
Press on the brake pedal, then push the park
brake switch momentarily. You may hear a
slight whirring sound from the back of the
vehicle while the parking brake disengages. You
may also notice a small amount of movement in the brake pedal. Once the park brake is fully
disengaged, the BRAKE warning lamp in the
instrument cluster and the LED indicator on the
switch will extinguish.
NOTE:
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. Apply the park brake before placing the
gear selector in PARK, otherwise the load on the
transmission locking mechanism may make it
difficult to move the gear selector out of PARK.
The park brake should always be applied when
-
ever the driver is not in the vehicle.
WARNING!
Never use the PARK position as a substi -
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
When exiting the vehicle, always make sure
the ignition is in the OFF mode, remove the
key fob from the vehicle, and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the key fob in or near the
vehicle, (or in a location accessible to chil -
dren), and do not leave the ignition in the
ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and
cause damage or injury. Also be certain to
leave the transmission in PARK. Failure to
do so may allow the vehicle to roll and
cause damage or injury.
WARNING! (Continued)

20_RU_OM_EN_US_t.book Page 226

STARTING AND OPERATING227
If exceptional circumstances should make it
necessary to engage the park brake while the
vehicle is in motion, push on the electric park
brake switch for as long as engagement is
desired. The BRAKE warning lamp will
illuminate, and a continuous chime will sound.
The rear stop lamps will also be illuminated
automatically while the vehicle remains in
motion. To disengage the park brake while the vehicle is
in motion, release the switch. If the vehicle is
brought to a complete stop using the park
brake, when the vehicle reaches approximately
3 mph (4.8 km/h), the park brake will remain
engaged.
In the unlikely event of a malfunction of the
Electric Park Brake system, a yellow EPB fault
lamp will illuminate. This may be accompanied
by the BRAKE warning lamp flashing. In this
case, urgent service of the electric park brake
system is required. Do not rely on the park
brake to hold the vehicle stationary.
Auto Park Brake
The Electric Park Brake can be programmed to
be applied automatically whenever the vehicle
is at a standstill and the automatic transmission
is placed in PARK. Auto Park Brake is enabled
and disabled by customer selection through the
“Customer Programmable Features” section of
the “Uconnect Settings”.
SafeHold
SafeHold is a safety feature of the Electric Park
Brake System that will engage the park brake
automatically if the vehicle is left unsecured. If
the automatic transmission is not in PARK, the
seat belt is unbuckled, the driver door is open,
the vehicle is at a standstill, and there is no
attempt to depress the brake pedal or
accelerator pedal, the park brake will
automatically engage to prevent the vehicle
from rolling.
SafeHold can be temporarily bypassed by
pushing the Electric Park Brake Switch while the
driver door is open and brake pedal is pressed.
Once manually bypassed, SafeHold will be
enabled again once the vehicle reaches
12 mph (20 km/h) or the ignition is cycled to
the OFF position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by
an authorized dealer. You should only make
repairs for which you have the knowledge and
the right equipment. You should only enter
Brake Service Mode during brake service.
When servicing your rear brakes, it may be
necessary for you or your technician to push the
rear piston into the rear caliper bore. With the
Driving the vehicle with the parking brake
engaged, or repeated use of the parking
brake to slow the vehicle may cause
serious damage to the brake system.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
WARNING!

20_RU_OM_EN_US_t.book Page 227

STARTING AND OPERATING233
If the transmission becomes extremely hot, the
“Transmission Temperature Warning Light” will
illuminate, a warning message will appear in the
instrument cluster, and the transmission may
operate differently until the transmission cools
down.
During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch, and shifts into 8th
or 9th gear, are inhibited until the transmission
fluid is warm refer to the “Note” under “Torque
Converter Clutch” in this section. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
LOW (L)
Use this range for engine braking when
descending very steep grades. In this range, the
transmission will downshift for increased
engine braking. To access the LOW position,
push down on the gear selector and rotate it
fully clockwise.
Transmission Limp Home Mode
Transmission function is monitored
electronically for abnormal conditions. If a
condition is detected that could result in
transmission damage, Transmission Limp
Home Mode is activated. In this mode, the
transmission may operate only in a fixed gear,
or may remain in NEUTRAL. The Malfunction
Indicator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be driven
to an authorized dealer for service without
damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK, if
possible. If not, shift the transmission to
NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds. 5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized dealer has diagnostic equipment to
assess the condition of your transmission. If the
transmission cannot be reset, authorized dealer
service is required.
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic
transmission on your vehicle. A clutch within the
torque converter engages automatically at
calibrated speeds. This may result in a slightly
different feeling or response during normal
operation in the upper gears. When the vehicle
speed drops or during some accelerations, the
clutch automatically disengages.
5

20_RU_OM_EN_US_t.book Page 233

234STARTING AND OPERATING
NOTE:
The torque converter clutch will not engage until
the engine and/or transmission is warm
(usually after 1 to 3 miles [2 to 5 km] of driving).
Because the engine speed is higher when the
torque converter clutch is not engaged, it may
seem as if the transmission is not shifting prop -
erly when the vehicle is cold. This is normal. The
torque converter clutch will function normally
once the powertrain is sufficiently warm.
ACTIVE NOISE CANCELLATION

Your vehicle is equipped with an Active Noise
Cancellation System. This system is designed
to address exhaust and engine noise. The
system relies on four microphones embedded
in the headliner, which monitor exhaust and
engine noise, and assists an onboard
frequency generator, which creates
counteracting sound waves in the audio
system’s speakers. This helps keep the vehicle
quiet at idle and during drive.

POWER STEERING
The electric power steering system will give you
good vehicle response and increased ease of
maneuverability in tight spaces. The system will
vary its assist to provide light efforts while
parking and good feel while driving. If the
electric steering system experiences a fault that
reduces assist or prevents the vehicle from
providing assist, you will still have the ability to
steer the vehicle manually.
If the Steering icon is displayed and the
“POWER STEERING SYSTEM OVER TEMP”
message is displayed on the instrument cluster
screen, they indicate that extreme steering
maneuvers may have occurred which caused
an over temperature condition in the power
steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few moments until the icon and message turn off.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
If the “SERVICE POWER STEERING"
OR "POWER STEERING ASSIST OFF -
SERVICE SYSTEM” message and a
steering wheel icon are displayed on
the instrument cluster screen, it indicates that
the vehicle needs to be taken to the dealer for
service. It is likely the vehicle has lost power
steering assistance. Refer to “Warning Lights
And Messages” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer
the vehicle. Under these conditions there will
be a substantial increase in steering effort,
especially at low speeds and during parking
maneuvers.
The power steering system is fully electric; it
requires no power steering fluid.
If the condition persists, see an authorized
dealer for service.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.
