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.

Driving your vehicle
FCA system is to reduce or to avoid
accident risk. It recognizes the dis-
tance 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 message or the warning
alarms and apply emergency brak-
ing.
❈FCA stands for Forward Collision-
Avoidance Assist.
❈Sensor fusion (front view camera
+ front radar) FCA system oper-
ates for the vehicle ahead, the
pedestrian or the cyclist in front.System setting and activation
Forward safety
The driver can activate FCA system
by placing the ignition switch or
ENGINE START/STOP button to the
ON position and by selecting:
“User Settings →Driver Assistance
→Forward Safety”
- If you select “Active Assist”, FCA
system activates. FCA produces
warning messages and warning
alarms in accordance with the col-
lision risk levels. Also, it controls
the brakes in accordance with the
collision risk levels.
- If you select “Warning Only”, FCA
system activates and produces
only warning alarms in accordance
with the collision risk levels. You
should control the brake directly
because FCA system do not con-
trol the brake.
- If you select “Off ”, FCA system
deactivates,

WARNING
Take the following precautions
when using Forward Collision-
Avoidance Assist system:
This system is only a supple-
mental system and it is not
intended to, nor does it replace
the need for the extreme care
and attention of the driver. The
sensing range and objects
detectable by the sensors are
limited. Pay attention to the
road conditions at all times.
NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. FCA system does not
stop the vehicle completely
and is only intended to help
mitigate an imminent colli-
sion.

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 system provides additional
braking power for optimum braking
performance, 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 system cannot avoid all
collisions. FCA system might
not completely stop the vehicle
before a collision, due to ambi-
ent, weather and road condi-
tions. The driver has the
responsibility to drive safely
and control the vehicle.
WARNING
FCA system operates in accor-
dance 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.

Driving your vehicle
WARNING
FCA system is only a supple-
mental system for the driver’s
convenience. The driver has
the ultimate responsibility to
control and operate the vehi-
cle safely. Do not solely
depend on FCA system.
Rather, maintain a safe brak-
ing distance, and, if neces-
sary, depress the brake pedal
to lower the driving speed.
In certain instances and
under certain driving condi-
tions, FCA system may acti-
vate unintentionally. This ini-
tial warning message appears
on the LCD display with a
warning chime.
(Continued)
(Continued)
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclist (if equipped) ahead.
FCA system may not activate
and the warning message will
not be displayed.
FCA system may unnecessar-
ily produce the warning mes-
sage and the warning alarms.
Also, due to the sensing limi-
tation, FCA system may not
produce the warning message
and the warning alarm at all.
When there is a malfunction
with FCA system, the braking
control does not operate upon
detecting a collision risk even
with other braking systems
normally operating.
(Continued)(Continued)
FCA system operates only for
the vehicle/pedestrian in
front, while driving forward. It
does not operate for any ani-
mals or vehicles in the oppo-
site direction.
FCA system does not recog-
nize the vehicle, which trans-
versally drives across the
crossroad, or the vehicle,
which is parked in the trans-
versal direction.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep safe
distance between your vehicle
and the vehicle in front of you.
FCA system may activate dur-
ing braking and the vehicle
may stop suddenly. And the
load in the vehicle may endan-
ger passengers. Therefore,
always be mindful of the load
volume in the vehicle.

Limitation of the system
FCA system is an assistant system
for a driver in a certain risky driving
condition and it does not take every
responsibility for all risks from driving
condition.
FCA system monitors the driving sit-
uations through the radar and the
camera sensor. Thus, for a situation
out of the sensing range, FCA sys-
tem may not normally operate. The
driver should pay great caution in the
following situations. FCA system
operation may be limited.(Continued)
FCA system may not activate
if the driver applies the brake
pedal to avoid risk of colli-
sion.
FCA system does not operate
when the vehicle is in reverse.
In these circumstances, you
must maintain a safe braking
distance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis
tance.
The regular braking function
will operate normally even if
There is a problem with the
FCA brake control system or
other functions. In this case,
the braking control will not
operate in an imminent colli-
sion.
(Continued)(Continued)
FCA system may not activate
according to driving condi-
tion, traffic on the road,
weather, road condition, etc.
FCA system may not activate
in response to all types of
vehicles.
