94GETTING TO KNOW YOUR VEHICLE
(Continued)
To move the crossbars, loosen the attachments,
located at the upper edge of each crossbar,
approximately eight turns using the anti-theft
wrench provided with the Mopar® crossbars.
Then, move the crossbar to the desired position,
keeping the crossbars parallel to the rack frame.
Once the crossbar is in the desired position,
retighten with the wrench to lock the crossbar into
position.
NOTE:If any cargo (or any metallic object) is placed over
the satellite radio antenna (if equipped), you may
experience interruption of satellite radio reception.
For improved satellite radio reception, place the
rear crossbar in the forward of the two rear
crossbar positions.
WARNING!
Cargo must be securely tied down before driving
your vehicle. Improperly secured loads can fly off
the vehicle, particularly at high speeds, resulting
in personal injury or property damage. Follow
the roof rack cautions when carrying cargo on
your roof rack.
CAUTION!
To prevent damage to the roof of your vehicle,
do not carry any loads on the roof rack without
the crossbars installed. The load should be
secured and placed on top of the crossbars,
not directly on the roof. If it is necessary to
place the load on the roof, place a blanket or
some other protection between the load and
the roof surface.
To avoid damage to the roof rack and vehicle,
do not exceed the maximum roof rack load
capacity of 150 lb (68 kg). Always distribute
heavy loads as evenly as possible and secure
the load appropriately.
Long loads which extend over the windshield,
such as wood panels or surfboards, or loads
with large frontal area should be secured to
both the front and rear of the vehicle.
Travel at reduced speeds and turn corners
carefully when carrying large or heavy loads
on the roof rack. Wind forces, due to natural
causes or nearby truck traffic, can add sudden
upward lift to a load. This is especially true on
large flat loads and may result in damage to
the cargo or your vehicle.
The use of vehicle systems that would adjust
the ride heights (such as Selec-Terrain modes
Rock or Sand/Mud) is not recommended
when using the Roof Luggage Rack to carry a
load.
CAUTION!

186STARTING AND OPERATING
(Continued)
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Úpage 184.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
The electronic TSC (if equipped) recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are used to tow small and
medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer Sway Control
(TSC) and a weight-distributing (load equalizing)
hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on
vehicle and trailer configuration/loading to comply
with Gross Axle Weight Rating (GAWR)
requirements.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.
WARNING!
If the gross trailer weight is 5,000 lb
(2,267 kg) or more, it is recommended to use
a weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control of
your vehicle and cause a collision.

SAFETY261
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in Rear
Cross Path (RCP) mode, the system will respond
with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime
mode, the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then activated,
and it corresponds to an alert present on that side
of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected
object are present on the same side at the same
time, both the visual and audible alerts will be
issued. In addition to the audible alert the radio (if
on) will also be muted.
NOTE:Whenever an audible alert is requested by the
BSM system, the radio is also muted. When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is also muted. Turn/
hazard signal status is ignored; the RCP state
always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will be
no visual or audible alerts from either the BSM or
RCP systems.
NOTE:The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started, the previously stored mode will
be recalled and used.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
The FCW with Mitigation system provides the driver
with audible warnings, visual warnings (within the
instrument cluster display), and may apply a
limited braking to warn the driver when it detects a
potential frontal collision. The warnings and limited
braking are intended to provide the driver with
enough time to react, avoid or mitigate the
potential collision.
NOTE:If either FCW or Pedestrian Emergency Braking
(PEB) is turned off, the FCW OFF Indicator Light will
illuminate. The FCW OFF Indicator Light will only
shut off if both features are turned on and active
braking is enabled.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision is probable, the driver will
be provided with audible and visual warnings and
may provide a brake jerk warning. If the driver does
not take action based upon these progressive
warnings, then the system will provide a limited
level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver
reacts to the warnings by braking and the system
determines that the driver intends to avoid the
collision by braking but has not applied sufficient
brake force, the system will compensate and
provide additional brake force as required.
6

23_WL_OM_EN_USC_t.book Page 261

SAFETY263
The “Near” setting may result in a lesser
number of FCW possible collision warnings
experienced.
NOTE:
Changing the FCW status to “Only Warning”
prevents the system from providing limited
active braking, or additional brake support if the
driver is not braking adequately in the event of
a potential frontal collision, but maintains the
audible and visual warnings.
Changing the FCW status to “Off” prevents the
system from providing autonomous braking, or
additional brake support if the driver is not
braking adequately in the event of a potential
frontal collision.
The system will retain the last setting selected
by the driver after ignition shut down.
FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects
not in the path of the vehicle, stationary objects
that are far away, oncoming traffic, or leading
vehicles with the same or higher rate of speed.
FCW will be disabled like ACC, with the unavail -
able screens.
FCW Limited Warning
If the instrument cluster displays “Automatic
Emergency Braking (AEB) Limited Service
Required” or “Limited Functionality Clean Front
Windshield” momentarily, there may be a
condition that limits FCW functionality. Although
the vehicle is still drivable under normal
conditions, the active braking may not be fully
available. Once the condition that limited the
system performance is no longer present, the
system will return to its full performance state. If
the problem persists, see an authorized dealer.
Service FCW Warning
If the system turns off, the instrument cluster
displays “AEB Unavailable Service Required.”
AEB Unavailable Service Required indicates there
is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the
system checked by an authorized dealer.
Pedestrian Emergency Braking (PEB) —
If Equipped
PEB is a subsystem of the Forward Collision
Warning (FCW) system which provides the driver
with audible warnings and visual warnings, in the
instrument cluster display. It may apply limited
automatic braking when it detects a potential
frontal collision with a pedestrian/cyclist.
PEB Message

If a PEB event begins at a speed below 39 mph
(62 km/h), the system may provide maximum
braking to mitigate the potential collision with a
pedestrian/cyclist. If the PEB event stops the
vehicle completely, the system will hold the vehicle
at a standstill for two seconds and then release the
brakes. When the system determines a collision
with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be
deactivated.
The minimum speed for PEB activation is 3 mph
(5 km/h).
6

23_WL_OM_EN_USC_t.book Page 263

264SAFETY
Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Control settings Ú page 204.
To turn the PEB system off, push the Pedestrian
Emergency Braking button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down. The system
will not reset to the default setting when the
vehicle is restarted.
Intersection Collision Assist (ICA) —
If Equipped
ICA uses three front radar sensors located in the
front fascia/bumper, to detect oncoming vehicles
from the front or side when driving through an
intersection. When the system determines that a
collision is probable when turning across
oncoming traffic, the system will attempt to
mitigate a possible collision by decelerating the
vehicle. When the system determines that a
collision with a crossing vehicle is probable, the
system may apply additional braking to
supplement the driver braking input to attempt to
mitigate a possible collision. The system will also
provide audible warnings and visual warnings
(shown in the instrument cluster). If the driver
determines acceleration is needed to avoid a
collision, when the accelerator is pressed ICA will
cancel.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold tire
pressure Ú page 408.
The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire
pressure will decrease. Tire pressure should always
be set based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less
than 1 mile (1.6 km) after a three-hour period. The
tire pressure will also increase as the vehicle is
driven — this is normal and there should be no
adjustment for this increased pressure.

For information on how to properly inflate the
vehicle’s tires, see Ú
page 374.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low pressure
warning threshold for any reason, including low
temperature effects, or natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists, and
will not turn off until the tire pressure is at or above
recommended cold tire pressure. Once the low tire
pressure warning has been illuminated, the tire
pressure must be increased to the recommended
cold tire pressure in order for the TPMS Warning
Light to be turned off.
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

Driver And Passenger Front Air Bag
Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system
provides output appropriate to the severity and
type of collision as determined by the Occupant
Restraint Controller (ORC), which may receive
information from the front impact sensors (if
equipped) or other system components. The first stage inflator is triggered immediately
during an impact that requires air bag deployment.
A low energy output is used in less severe
collisions. A higher energy output is used for more
severe collisions.
This vehicle may be equipped with a driver and/or
front passenger seat belt buckle switch that
detects whether the driver or front passenger seat
belt is buckled. The seat belt buckle switch may
adjust the inflation rate of the Advanced Front Air
Bags.
This vehicle may be equipped with driver and/or
front passenger seat track position sensors that
may adjust the inflation rate of the Advanced Front
Air Bags based upon seat position.
This vehicle is equipped with a right front
passenger Occupant Classification System (“OCS”)
that is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s
seated weight input, as determined by the OCS.
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.
WARNING!
Being too close to the steering wheel or instru
-
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfort -
ably extending your arms to reach the steering
wheel or instrument panel.
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
No objects should be placed over or near the
air bag on the instrument panel or steering
wheel because any such objects could cause
harm if the vehicle is in a collision severe
enough to cause the air bag to inflate.
Do not put anything on or around the air bag
covers or attempt to open them manually. You
may damage the air bags and you could be
injured because the air bags may no longer be
functional. The protective covers for the air
bag cushions are designed to open only when
the air bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.
WARNING!
