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 additional
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 vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.

Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing 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 FCA brake control is automat- ically canceled, when risk factors
disappear.
FCA Sensor
In order for the FCA system to oper-
ate properly, always make sure the
radar sensor cover is clean and free
of dirt, snow, and debris. Dirt, snow,
or foreign substances on the lens
may adversely affect the sensing
performance of the sensor.
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the FCA system.
CAUTION
The braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
FCA system.
WARNING

Driving your vehicle(Continued)
Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.(Continued)
(Continued)
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system operates
only to help detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.(Continued)
WARNING
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and
under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also, in certain instances the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message will not be
displayed.(Continued)

Limitations of the System
The Forward Collision-Avoidance
Assist (FCA) system is designed to
help monitor the vehicle ahead or a
pedestrian in the roadway through
radar signals and camera recognition
to warn the driver that a collision is
imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked with a foreign object or
debris
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
There is interference by electro- magnetic waves There is severe irregular reflection
from the radar sensor
The radar/camera sensor recogni- tion is limited
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, etc.)
The vehicle in front is an oversize vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
The driver's field of view is not well illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
The vehicle in front does not have their rear lights properly turned ON
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel
Light coming from a street light or an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
The field of view in front is obstructed by sun glare
The windshield glass is fogged up; a clear view of the road is obstructed
(Continued)
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.

5-52
Driving your vehicle
The vehicle in front is driving errat- ically
The vehicle is on unpaved or uneven rough surfaces, or road
with sudden gradient changes.
The vehicle is driven near areas containing metal substances as a
construction zone, railroad, etc.
The vehicle drives inside a build- ing, such as a basement parking
lot
The adverse road conditions cause excessive vehicle vibrations while
driving
The sensor recognition changes suddenly when passing over a
speed bump
The vehicle in front is moving verti- cally to the driving direction
The vehicle in front is stopped ver- tically
The vehicle in front is driving towards your vehicle or reversing - Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
On curved roads, the other vehicle
on the same lane is not recognized
and the FCA system's performance
may be degraded. This may result in
unnecessary alarm or braking or no
alarm or braking when necessary.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road. In these cases, the driver must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
