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.
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 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.

Supplemental Side Air Bag Inflatable Curtain (SABIC)
Label Location

SABICs may help reduce the risk of head and
other injuries to front and rear seat outboard
occupants in certain side impacts, in addition to
the injury reduction potential provided by the
seat belts and body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers
the window. The SABICs inflate with enough
force to injure occupants if they are not belted
and seated properly, or if items are positioned
in the area where the SABICs inflate. Children
are at an even greater risk of injury from a
deploying air bag.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants through side windows in certain side impact
events.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the
appropriate response to impact events. The
system is calibrated to deploy the Side Air Bags
on the impact side of the vehicle during impacts
that require Side Air Bag occupant protection. In
side impacts, the Side Air Bags deploy
independently; a left side impact deploys the
left Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at certain
angles, or some side collisions that do not
impact the area of the passenger compartment.
The Side Air Bags may deploy during angled or
offset frontal collisions where the front air bags
deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes.
WARNING!
Do not mount equipment, or stack luggage
or other cargo up high enough to block the
deployment of the SABICs. The trim
covering above the side windows where the
SABIC and its deployment path are located
should remain free from any obstructions.
In order for the SABICs to work as intended,
do not install any accessory items in your
vehicle which could alter the roof. Do not
add an aftermarket sunroof to your vehicle.
Do not add roof racks that require perma
-
nent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill
into the roof of the vehicle for any reason.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system. If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the occu
-
pants as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or
those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not perma -
nent and normally heal quickly. However, if
you haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.

As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or
throat irritation, move to fresh air. If the irrita -
tion continues, see your doctor. If these parti -
cles settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
NOTE:
Air bag covers may not be obvious in the inte
-
rior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as well.

STARTING AND OPERATING239
To Decrease Speed
When the Speed Control is set, you can
decrease speed by pushing the SET (-) button.
The driver’s preferred units can be selected
through the instrument panel settings. Refer to
”Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed increment shown is
dependent on the chosen speed unit of U.S.
(mph) or Metric (km/h):
U.S. Speed (mph)
Pushing the SET (-) button once will result in
a 1 mph decrease in set speed. Each subse -
quent tap of the button results in a decrease
of 1 mph.
If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established. Metric Speed (km/h)
Pushing the SET
(-) button once will result in
a 1 km/h decrease in set speed. Each subse -
quent tap of the button results in a decrease
of 1 km/h.
If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established.
To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Speed
Control without erasing the set speed from
memory. Pushing the on/off button or placing the ignition
in the OFF position erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions.
Speed
Control function performs differently. Please
refer to the proper section within this chapter.
ACC will allow you to keep cruise control
engaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a
vehicle directly ahead of you.
5

20_RU_OM_EN_US_t.book Page 239

240STARTING AND OPERATING
(Continued)
NOTE:

If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
The Cruise Control system has two control
modes:
Adaptive Cruise Control mode for maintaining
an appropriate distance between vehicles.
Normal (Fixed Speed) Cruise Control mode for
cruising at a constant preset speed. For addi -
tional information, refer to “Normal (Fixed
Speed) Cruise Control Mode” in this section.

NOTE:
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware of
the mode selected.
You can change the mode by using the Cruise
Control buttons. The two control modes
function differently. Always confirm which mode
is selected.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake opera -
tion to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle.
Failure to follow these warnings can result
in a collision and death or serious personal
injury.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for approximately 3 minutes
in the stop position. If the target vehicle
does not start moving within 3 minutes
the parking brake will be activated, and
the ACC system will be cancelled.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc -
tion zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.
WARNING! (Continued)

20_RU_OM_EN_US_t.book Page 240

246STARTING AND OPERATING
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor -
mation on ACC Activation).
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the
instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.
Brake Alert

NOTE:
The “BRAKE!” Screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal and will only be active when passing on
the left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a
standstill while following a target vehicle, your
vehicle will resume motion, without any driver
interaction, if the target vehicle starts moving
within two seconds.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a
standstill, the driver will either have to push the
RES (resume) button, or apply the accelerator
pedal to reengage the ACC. The vehicle will
accelerate to the existing set speed.
NOTE:
After the ACC system holds your vehicle at a
standstill for approximately three consecutive
minutes, the parking brake will be activated,
and the ACC system will be cancelled.
While the ACC system is holding your vehicle at
a standstill, if the driver seatbelt is unbuckled or
the driver door is opened, the parking brake will
be activated, and the ACC system will be
cancelled.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of
Vehicle” Warning
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and also a chime will indicate when conditions temporarily limit
system performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will show
“ACC/FCW Unavailable Wipe Front Radar
Sensor” and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e.
tunnels with reflective tiles, or ice and snow).
The ACC system will recover after the vehicle
has left these areas. Under rare conditions,
when the radar is not tracking any vehicles or
objects in its path this warning may temporarily
occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed)
Cruise Control is still available. For additional
information refer to “Normal (Fixed Speed)
Cruise Control Mode” in this section.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in
a collision and death or serious personal
injury.

20_RU_OM_EN_US_t.book Page 247

248STARTING AND OPERATING
If weather conditions are not a factor, the driver
should examine the sensor. It may require
cleaning or removal of an obstruction. The
sensor is located in the center of the vehicle
behind the lower grille.
To keep the ACC System operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully wipe
the sensor lens with a soft cloth. Be cautious
not to damage the sensor lens.
Do not remove any screws from the sensor.
Doing so could cause an ACC system
malfunction or failure and require a sensor
realignment.
If the sensor or front end of the vehicle is
damaged due to a collision, see an autho -
rized dealer for service.
Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction. When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function by simply reactivating it.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the radar
sensor realigned at an authorized dealer.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean
Front Windshield” warning will display and also
a chime will indicate when conditions
temporarily limit system performance. This
most often occurs at times of poor visibility,
such as in snow or heavy rain and fog. The ACC
system may also become temporarily blinded
due to obstructions, such as mud, dirt, or ice on
windshield, driving directly into the sun and fog
on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield”
and the system will have degraded
performance. The “ACC/FCW Limited Functionality Clean
Front Windshield” message can sometimes be
displayed while driving in adverse weather
conditions. The ACC/FCW system will recover
after the vehicle has left these areas. Under
rare conditions, when the camera is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of
an obstruction.
When the condition that created limited
functionality is no longer present, the system
will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently
(e.g. more than once on every trip) without any
snow, rain, mud, or other obstruction, have the
windshield and forward facing camera
inspected at an authorized dealer.

ParkSense Sensors
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depending
on the location, type and orientation of the
obstacle.

Rear Sensor Locations

ParkSense Visual Alert
The ParkSense Warning screen will only be
displayed if Sound and Display is selected from
the Customer - Programmable Features section
of the Uconnect System. Refer to "Uconnect
Settings” in “Multimedia” for further
information.
The ParkSense Warning screen is located within
the instrument cluster display. It provides visual
warnings to indicate the distance between the
rear fascia/bumper and the detected obstacle.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
ParkSense Display
When the vehicle is in REVERSE and an
obstacle has been detected, the warning
display will turn on indicating the system status,
and remain on until the vehicle is moved out of
REVERSE. The system will indicate a detected obstacle by
showing a single arc in one or more regions
based on the obstacle’s distance and location
relative to the vehicle.
If an obstacle is detected in the center rear
region, the display will show a single solid arc in
the center rear region and will produce a
one-half second tone. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the
sound tone will change from slow, to fast, to
continuous.
If an obstacle is detected in the left and/or right
rear region, the display will show a single
flashing arc in the left and/or right rear region
and will produce a fast sound tone. As the
vehicle moves closer to the obstacle, the
display will show the single arc moving closer to
the vehicle and the tone will change from fast to
continuous.

NOTE:
When the KeySense feature is in use, the Park -
Sense System will reject customer input to turn
the system off via the switch. The instrument
cluster display will show the "KeySense in Use
Selected Feature Cannot be Disabled"
message.
Service The ParkSense Rear Park Assist
System

During vehicle start-up, when the ParkSense
Rear Park Assist System has detected a faulted
condition, the instrument cluster will actuate a
single chime, once per ignition cycle, and it will
display the “PARKSENSE UNAVAILABLE WIPE
REAR SENSORS” or the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message.
Refer to “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further
information. When the gear selector is moved to
REVERSE and the system has detected a faulted
condition, the instrument cluster display will
show the "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" message for five seconds
while the vehicle is in REVERSE. Under this
condition, ParkSense will not operate and
“PARKSENSE OFF” message will be displayed.
If “PARKSENSE UNAVAILABLE WIPE REAR
SENSORS” appears in the instrument cluster
display, make sure the outer surface and the
underside of the rear fascia/bumper is clean
and clear of snow, ice, mud, dirt, or other
obstruction and then cycle the ignition. If the
message continues to appear, see an
authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE
REQUIRED” appears in the instrument cluster
display, see an authorized dealer.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car
wash soap, and a soft cloth. Do not use rough or
hard cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the rear bumper is free of snow,
ice, mud, dirt, and debris to keep the Park
-
Sense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF”.
Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if
you cycle the ignition.
When you move the gear selector to the
REVERSE position and ParkSense is turned
off, the instrument cluster display will show
“PARKSENSE OFF” message for as long as
the vehicle is in REVERSE.
ParkSense, when on, will reduce the volume
of the radio when it is sounding a tone.
Clean the ParkSense sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt, or debris. Failure to do
so can result in the system not working prop -
erly. The ParkSense system might not detect
an obstacle behind the fascia/bumper, or it
could provide a false indication that an
obstacle is behind the fascia/bumper.
