If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of Anti-Lock Brakes. If the ABS
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
DROWSY DRIVER DETECTION (DDD) —
I
F EQUIPPED
DDD detects when the driver is feeling fatigued
and warns the driver to pull over and take a break.
To Activate/Deactivate

DDD can be activated and deactivated through the
Uconnect system by selecting the following in order:

1. “Safety & Driving Assistance”

2. “Drowsy Driver Detection”
System Operation
Using feedback obtained from the driver’s steering
patterns, any buttons/switches that are pressed,
and from the front camera, the system implements
two operating logics:
The first operating logic takes the driving style
into account, observing the road and detecting
to what extent the driver can continue driving
with few lane crossing events.
The second operating logic measures the time
spent behind the wheel with the vehicle speed
above 40 mph (60 km/h) and below 100 mph
(160 km/h).
If the driving style indicates that the driver is
unable to follow the road trajectory and respect the
horizontal lane markings while within the operating
speed range of the system, a pop up will display on
the instrument cluster display to suggest that the
driver should stop for a break. An audible signal
will also sound.
If the driver accepts the suggestion provided by the
system by pushing the “OK” button on the left side
of the steering wheel, the message will disappear
from the display.
If the driver does not acknowledge the warning, it
will be displayed for 60 seconds and then
disappear.
NOTE:In the event of a DDD system failure, a dedicated
message will appear in the instrument cluster
display.

DDD Warning Message

REAR SEAT REMINDER ALERT (RSRA)
RSRA alerts you through a visual and auditory
notification of the possible presence of an object,
passenger, or pet in the rear seats if a rear door
was opened up to 10 minutes before the ignition
was placed in the ON/RUN position. RSRA does not
directly detect objects, passengers, or pets in the
rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on
the instrument cluster display and sounds an
auditory alert upon the driver placing the ignition in
the OFF position to exit the vehicle.
To enable or disable RSRA, see Ú page 204.WARNING!
The DDD system is an aid for driving and does
not relieve the driver of the responsibility of
driving the vehicle. Always drive alert and get
plenty of rest before driving. If you experience
fatigue while driving, do not wait for the DDD to
intervene with a warning. Choose a safe and
secure location where you can pull over safely
for a break. Only return to the road when you are
in the right physical and mental condition to
prevent endangering yourself and others.

AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM)
BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear. The BSM detection zone covers approximately one
lane in width on both sides of the vehicle 12 ft
(3.8 m). The zone length starts at the side of the
vehicle, near the B-pillar, and extends
approximately 10 ft (3 m) beyond the rear fascia/
bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle
when the vehicle speed reaches approximately
6 mph (10 km/h) or higher and will alert the driver
of vehicles in these areas. BSM will alert earlier on
faster-approaching vehicles — up to 33 mph
(54 km/h) difference.
NOTE:The BSM system detection zone DOES NOT change
if your vehicle is towing a trailer. Therefore, visually
verify the adjacent lane is clear for both your
vehicle and trailer before making a lane change. If
the trailer or other object (i.e., bicycle, sports
equipment) extends beyond the side of your
vehicle, this may result in random false detections
on the trailer, and false chimes when the turn
signal is used Ú
page 204. The BSM system can become blocked if snow, ice,
mud, or other road contaminations accumulate on
the rear fascia/bumper where the radar sensors
are located. The system may also detect blockage
if the vehicle is operated in areas with extremely
low radar returns such as a desert or parallel to a
large elevation drop. If blockage is detected, a
“Blind Spot Temporarily Unavailable, Sensor
Blocked” message will display in the cluster, both
mirror lights will illuminate, and BSM and RCP
alerts will not occur. This is normal operation. The
system will automatically recover and resume
function when the condition clears or when an
ignition cycle occurs. To minimize system
blockage, do not block the area of the rear fascia/
bumper where the radar sensors are located with
foreign objects (bumper stickers, bicycle racks,
etc.) and keep it clear of road contaminations.

Sensor Location (Left Side Shown)

23_WL_OM_EN_USC_t.book Page 258

SAFETY259
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM Warning
Light located in the outside mirrors. In addition,
when the turn signal is activated during the alert on
the side of the vehicle corresponding to the alert,
an audible (chime) alert can be heard. During this
audible (chime) alert, the radio volume will be
reduced Ú page 260.

BSM Warning Light

The BSM system monitors the detection zone from
three different entry points (Side, Rear, Front)
while driving to see if an alert is necessary. The
BSM system will issue an alert during these types
of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from
either side of the vehicle.
Side Monitoring

Entering From The Rear
Vehicles that come up from behind your vehicle on
either side and enter the rear detection zone with
a relative speed of less than 33 mph (54 km/h).
Fast approaching vehicles will receive an earlier
alert based on relative speed.

Rear Monitoring
Overtaking Traffic
If you pass another vehicle slowly with a relative
speed of less than 15 mph (24 km/h) the warning
light will be illuminated. If the difference in speed
between the two vehicles is greater than 15 mph
(24 km/h), the warning light will not illuminate.

260SAFETY

The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls,
foliage, berms, etc. However, occasionally the
system may alert on such objects. This is normal
operation and your vehicle does not require service.

The BSM system will not alert you of objects that
are traveling in the opposite direction of the vehicle
in adjacent lanes Ú page 408.

Opposing Traffic

Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver.
RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 5 mph (8 km/h), to objects
moving a maximum of approximately 20 mph
(32 km/h), such as in parking lot situations.
NOTE:In a parking lot situation, oncoming vehicles can be
obscured by vehicles parked on either side. If the
sensors are blocked by other structures or
vehicles, the system will not be able to alert the
driver.
When RCP is on (Blind Spot Lights Only or Blind
Spot Lights/Chimes) and the vehicle is in
REVERSE, the driver is alerted using both the
visual and audible alarms, including reducing the
radio volume.
Blind Spot Modes
Three selectable modes of operation are available
in the Uconnect system Ú page 204.
WARNING!

The Blind Spot Monitoring system is only an aid to
help detect objects in the blind spot zones. The
BSM system is not designed to detect pedestrians,
bicyclists, or animals. Even if your vehicle is
equipped with the BSM system, always check your
vehicle’s mirrors, glance over your shoulder, and
use your turn signal before changing lanes. Failure
to do so can result in serious injury or death.

WARNING!
Rear Cross Path (RCP) Detection is not a back up
aid system. It is intended to be used to help a
driver detect a vehicle in a parking lot situation.
Drivers must be careful when backing up, even
when using RCP. Always check carefully behind
your vehicle, look behind you, and be sure to
check for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up.
Failure to do so can result in serious injury or
death.

23_WL_OM_EN_USC_t.book Page 260

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.

268SAFETY
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE TPM
SYSTEM” message in the instrument cluster but
dashes (--) will remain in place of the pressure
values.
To reactivate the TPMS, replace all four wheel and
tire assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on
and off for 75 seconds and then turn off. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display pressure
values in place of the dashes. On the next ignition
cycle the "SERVICE TPM SYSTEM" message will no
longer be displayed as long as no system fault
exists.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Tire Fill Alert feature in the apps menu of the
Uconnect system.
NOTE:
The Tire Fill Alert system will only support
inflating or deflating one tire at a time. The user
is required to wait until the hazard lights STOP flashing or 26-30 seconds after the desired
pressure is achieved in one wheel before
switching to another.
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the
system is in deactivation mode (if equipped).
The system will be activated when the system
detects an increase in tire pressure while filling the
tire. The ignition must be in the ON/RUN mode with
the transmission in PARK for vehicles equipped
with an automatic transmission. For vehicles
equipped with a manual transmission, the parking
brake must be applied.
NOTE:It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode. If the hazard lamps
do not come on while inflating the tire, the Tire
Pressure Monitoring System sensor may be in an
inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle
may need to be moved slightly forward or
backward.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster. Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over
-
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
Selectable Tire Fill Alert (STFA) —
If Equipped
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate
or deflate the vehicle's front and rear axle tires to,
and to provide feedback while inflating or deflating
the vehicle's tires.

3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 289.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are
using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow the
front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between occupants and the
door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person,
see Úpage 403 for customer service contact
information.
SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver,
even on short trips. Someone on the road may be
a poor driver and could cause a collision that
includes you. This can happen far away from home
or on your own street.
Research has shown that seat belts save lives, and
they can reduce the seriousness of injuries in a
collision. Some of the worst injuries happen when
people are thrown from the vehicle. Seat belts
reduce the possibility of ejection and the risk of
injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all
times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind
the driver and outboard front seat
passenger (if equipped with outboard
front passenger seat BeltAlert) to buckle
their seat belts. The BeltAlert feature is active
whenever the ignition switch is in the START or ON/
RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch
is first in the START or ON/RUN position, a chime
will signal for a few seconds. If the driver or
outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is
unbuckled when the ignition switch is first in the
START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard
front seat belts are buckled. The outboard front
passenger seat BeltAlert is not active when an
outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when
the vehicle is moving above a specified vehicle
speed range and the driver or outboard front seat
passenger is unbuckled (if equipped with outboard
front passenger seat BeltAlert) (the outboard front
passenger seat BeltAlert is not active when the
WARNING!
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.

23_WL_OM_EN_USC_t.book Page 270

280SAFETY
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and damage
by themselves are not good indicators of whether
or not an air bag should have deployed.
Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.

When the Occupant Restraints Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of non-toxic
gas is generated to inflate the front air bags.

The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
Occupant Classification System (OCS) —
Front Passenger Seat

The Occupant Classification System (OCS) is part of a
Federally regulated safety system for this vehicle. It is
designed to provide Passenger Advanced Front Air
Bag output appropriate to the occupant’s seated
weight, as determined by the OCS.
The Occupant Classification System (OCS) consists
of the following:
Occupant Restraint Controller (ORC)
Occupant Classification Module (OCM) and
Sensor located in the front passenger seat
Air Bag Warning Light
Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is
located underneath the front passenger seat. The
Sensor is located beneath the passenger seat
cushion foam. Any weight on the seat will be
sensed by the Sensor. The OCM uses input from
the Sensor to determine the front passenger’s
most probable classification. The OCM
communicates this information to the ORC. The
ORC may reduce the inflation rate of the Passenger
Advanced Front Air Bag deployment based on
occupant classification. In order for the OCS to
operate as designed, it is important for the front
passenger to be seated properly and properly
wearing the seat belt.
The OCS will NOT prevent deployment of the
Passenger Advanced Front Air Bag. The OCS may
reduce the inflation rate of the Passenger
Advanced Front Air Bag if the OCS estimates that:
The front passenger seat is unoccupied or has
very light objects on it; or
The front passenger seat is occupied by a small
passenger, including a child; or
The front passenger seat is occupied by a
rear-facing child restraint; or
The front passenger is not properly seated or his
or her weight is taken off of the seat for a period
of time.
* It is possible for a child to be classified as an
adult, allowing a full-power Passenger Advanced
Front Air Bag deployment. Never allow children to
ride in the front passenger seat and never install a
child restraint system, including a rear-facing child
restraint, in the front passenger seat.

SAFETY283
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.
WARNING!
If a child restraint system, child, small teen
-
ager or adult in the front passenger seat is
seated improperly, the occupant may provide
an output signal to the OCS that is different
from the occupant’s properly seated weight
input. This may result in serious injury or death
in a collision.
Always wear your seat belt and sit properly,
with the seatback in an upright position, your
back against the seatback, sitting upright,
facing forward, in the center of the seat, with
your feet comfortably on or near the floor.
Do not carry or hold any objects (e.g., back -
packs, boxes, etc.) while seated in the front
passenger seat. Holding an object may
provide an output signal to the OCS that is
different than the occupant’s properly seated
weight input, which may result in serious injury
or death in a collision.
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!
Unapproved modifications or service proce-
dures to the passenger seat assembly, its
related components, seat cover or cushion
may inadvertently change the air bag deploy -
ment 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 colli -
sion. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Stan -
dards (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 autho -
rized dealer.
