Safety features of your vehicle
They may inflate in other types of
collisions where a side force is
detected by the sensors. Side air bag
and/or curtain air bags may also
inflate where rollover sensors indi-
cate the possibility of a rollover
occurring (even if none actually
occurs) or in other situations, includ-
ing when the vehicle is tilted while
being towed.
Even where side and/or curtain air
bags would not provide impact pro-
tection in a rollover, however, they
will deploy to prevent ejection of
occupants, especially those who are
restrained with seat belts.
If the vehicle chassis is impacted by
bumps or objects on unimproved
roads, the air bags may deploy. Drive
carefully on unimproved roads or on
surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.Air bag non-inflation conditions
In certain low-speed collisions the
air bags may not deploy. The air
bags are designed not to deploy in
such cases because they may not
provide benefits beyond the pro-
tection of the seat belts in such col-
lisions.
Air bags are not designed to inflate
in rear collisions, because occu-
pants are moved backward by the
force of the impact. In this case,
inflated air bags would not be able
to provide any additional benefit.
Front air bags may not inflate in
side impact collisions, because
occupants move to the direction of
the collision, and thus in side
impacts, frontal air bag deployment
would not provide additional occu-
pant protection.
In an angled collision, the force of
impact may direct the occupants in
a direction where the air bags would
not be able to provide any addition-
al benefit, and thus the sensors may
not deploy any air bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehi-
cle causing it to “ride” under a vehi-
cle with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because
deceleration forces that are detect-
ed by sensors may be significantly
reduced by such “under-ride” colli-
sions.
Front air bags may not inflate in all
rollover accidents where the
SRSCM indicates that the front air
bag deployment would not provide
additional occupant protection.
Air bags may not inflate if the vehi-
cle collides with objects such as util-
ity poles or trees, where the point of
impact is concentrated to one area
and the full force of the impact is not
delivered to the sensors.

This function will activate when
backing up with the ignition switch
or ENGINE START/STOP button to
the ON position.
If the vehicle is moving at a speed
over 3 mph (5 km/h), the function
may not be activated correctly.
The sensing distance while the
back-up warning function is in
operation is approximately 48 in
(120 cm) at the rear bumper center
area, 24 in (60 cm) at the rear
bumper both side area.
When more than two objects are
sensed at the same time, the clos-
est one will be recognized first.
Types of warning sound
When an object is 24 in to 48 in (60
cm to 120 cm) from the rear
bumper: Buzzer beeps intermit-
tently.
When an object is 12 in to 24 in (30
cm to 60 cm) from the rear
bumper: Buzzer beeps more fre-
quently.
When an object is within 12 in (30
cm) of the rear bumper:
Buzzer sounds continuously.

WARNING
FCA is only a supplemental
function for the driver’s con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on FCA.
Rather, maintain a safe braking
distance, and, if necessary,
depress the brake pedal to
lower the driving speed.
In certain instances and
under certain driving condi-
tions, FCA may activate unin-
tentionally. This initial warning
message appears on the LCD
display with a warning chime.
Also, in certain instances the
front radar sensor or front
view camera recognition func-
tion may not detect the vehi-
cle or pedestrian ahead. FCA
may not activate and the
warning message will not be
displayed.

FCA is to reduce or to avoid accident
risk. It recognizes the distance from
the vehicle ahead, the pedestrian or
the cyclist through the sensors (i.e.
front view camera and front radar),
and, if necessary, warns the driver of
accident risk with the warning mes-
sage or the warning alarms and
apply emergency braking.

Brake operation
In an urgent situation, the braking
system enters into the ready status
for prompt reaction to assist the driv-
er in depressing the brake pedal.
FCA provides additional braking
power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical-
ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The braking control is automatical-
ly canceled, when risk factors dis-
appear.
Detecting sensors (Front view
camera/Front radar)
The sensors are that detecting the
distance to vehicles ahead, pedestri-
an or cyclist.
CAUTION
The driver should always pay
great caution to vehicle opera-
tion, even though there is no
warning message or warning
alarm.
WARNING
FCA cannot avoid all collisions.
FCA might not completely stop
the vehicle before a collision,
due to ambient, weather and
road conditions. The driver has
the responsibility to drive safely
and control the vehicle.
WARNING
FCA operates in accordance
with certain risk factors, such as
the distance from the
vehicle/passer-by in front, the
speed of the vehicle/passer-by in
front, and the driver's vehicle
operation.ODEP059029

Limitation of the function
FCA is an assistant function for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
FCA monitors the driving situations
through the front radar and the front
view camera sensor. Thus, for a situ-
ation out of the sensing range, FCA
may not normally operate. The driver
should pay great caution in the fol-
lowing situations. FCA operation may
be limited.
Recognizing vehicles
The sensor may be limited when:
The front view camera or front
radar sensor is blocked with a for-
eign object or debris
The front view camera lens is con-
taminated due to tinted, filmed or
coated windshield, damaged
glass, or stuck of foreign matter
(sticker, bug, etc.) on the glass
Inclement weather such as heavy
rain or snow obscures the field of
view of the front radar sensor or
front view camera
There is interference by electro-
magnetic waves
There is severe irregular reflection
from the front view camera sensor
The front view camera/front radar
sensor recognition is limited
The vehicle in front is too small to
be detected (for example a motor-
cycle etc.)
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the front view cam-
era recognition function (for exam-
ple a tractor trailer, etc.)(Continued)
The regular braking function
will operate normally even if
There is a problem with FCA
brake control function or
other functions. In this case,
the braking control will not
operate in an imminent colli-
sion.
FCA may not activate accord-
ing to driving condition, traffic
on the road, weather, road
condition, etc.
FCA may not activate in
response to all types of vehi-
cles.
