Safety system of your vehicle

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 front air
bag deployment would not provide
additional occupant protection.
Information
The side and/or curtain air bags may
inflate when the vehicle is rolled over
by a side impact collision, if the vehi-
cle is equipped with side and/or cur-
tain air bags.

The indicator may differ from the illustration depending on objects or
sensors status. If the indicator blinks, we recommend that the system
be checked by an authorised HYUNDAI dealer.
If the audible warning does not sound or if the buzzer sounds inter-
mittently when shifting into R (Reverse) position, this may indicate a
malfunction with the Reverse/Forward Parking Distance Warning sys-
tem. If this occurs, we recommend that you have your vehicle checked
by an authorised HYUNDAI dealer as soon as possible.

Driving your vehicle
FCA sensor
In order for the FCA system to oper-
ate properly, always make sure the
sensor cover or sensor is clean and
free of dirt, snow, and debris.
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehi-
cle, pedestrian or cyclist (if
equipped) ahead, the speed of
the vehicle ahead, and the dri-
ver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
FCA system.
WARNING OAE058028
OAE058048
■ Front radar
■ Front camera
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
The driver should always use
extreme caution whilst oper-
ating the vehicle, whether or
not there is a warning mes-
sage or alarm from the FCA
system.
After the brake control is acti-
vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-
onds.
If any other warning sound
such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
CAUTION

The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light. Both FCA
warning light and warning mes-
sage will disappear once the ESC
warning light issue is resolved.
FCA is only a supplemental
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 or to stop the vehicle.
(Continued)(Continued)
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 due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclist (if equipped) ahead.
The FCA system may not acti-
vate and the warning mes-
sage may not be displayed.
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.
(Continued)
WARNING
(Continued)
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 collision.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
(Continued)

5-64
Driving your vehicle
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.
You are on a roundabout and the
vehicle in front circles.
Driving on a curve
The performance of the FCA sys-
tem 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 perform-
ance 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
maintain a safe braking distance,
and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance.

Detecting the vehicle in front of you
If the vehicle in front of you has
cargo that extends rearward from
the cab, or when the vehicle in
front of you has higher ground
clearance, additional special atten-
tion is required. The FCA system
may not be able to detect the cargo
extending from the vehicle. In
these instances, you must main-
tain a safe braking distance from
the rearmost object, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain distance.
Detecting pedestrians or
cyclists (if equipped)
The sensor may be limited when:
The pedestrian or cyclist is not fully
detected by the camera recogni-
tion system, for example, if the
pedestrian is leaning over or is not
fully walking upright
The pedestrian or cyclist is moving
very quickly or appears abruptly in
the camera detection area
The pedestrian or cyclist is wear-
ing clothing that easily blends into
the background, making it difficult
to be detected by the camera
recognition system
The outside lighting is too bright
(e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night)
It is difficult to detect and distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclists or a large
crowd There is an item similar to a per-
son's body structure
The pedestrian or cyclist is small
The pedestrian has impaired
mobility
The sensor recognition is limited
The radar sensor or camera is
blocked 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
When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle in the road
The field of view in front is
obstructed by sun glare
The windscreen glass is fogged
up; a clear view of the road is
obstructed
The adverse road conditions cause
excessive vehicle vibrations whilst
driving
The sensor recognition changes
suddenly when passing over a
speed bump

Driving your vehicle
Lane changing
A vehicle which moves into your
lane from an adjacent lane cannot
be recognised by the sensor until it
is in the sensor's detection range.
The radar may not detect immedi-
ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your
lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
If a faster vehicle which moves into
your lane, your vehicle will acceler-
ate to the set speed.
Vehicle recognition
Some vehicles in your lane cannot
be recognised by the sensor:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile
such as trailers with no loadsA vehicle ahead cannot be recog-
nised correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- Whilst the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary.
