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.

The ISG system helps reduce fuel
consumption and exhaust gas emis-
sions by automatically shutting down
the engine, when the vehicle is at a
standstill (i.e. red stop light, stop
sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
The driver's seatbelt is fastened
The driver's door and hood areclosed
The brake vacuum pressure is adequate
The battery sensor is activated and the battery is sufficiently
charged
Outside temperature is not too low or too high
The vehicle is driven over a con- stant speed and stops
The climate control system satis- fies the conditions
The vehicle is sufficiently warmed up
The incline is gradual
The steering wheel is turned less than 180 degrees and then the
vehicle stops
Information
The ISG system is
not activated, when
the prerequisites to
activate the ISG sys-
tem are unsatisfied.
In this case, the ISG
OFF button indicator illuminates,
and the auto stop indicator ( )
illuminates in yellow on the instru-
ment cluster.
• When the above indicator remains illuminated on the instrument clus-
ter, we recommend that you have
the ISG system checked by an
authorized HYUNDAI dealer.

Battery Sensor Deactivation
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate thebattery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the ISG
system.
- The battery is weak.
- The brake vacuum pressure is low.
If this occurs, have the ISG system
checked by an authorized HYUNDAI
dealer. Use only a genuine HYUNDAI
ISG battery for replacement. If
not, the ISG system may not nor-
mally operate.
Do not recharge the ISG battery with a general battery charger. It
may damage or explode the ISG
battery.
Do not remove the battery cap. The battery electrolyte, which is
harmful to the human body, may
leak out.

Driving your vehicle
The Forward Collision-Avoidance
Assist (FCA) system is designed to
help detect and monitor the vehicle
ahead or help detect 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.
System Setting and Activation
System setting
The driver can activate the FCA by placing the ignition switch to the
ON position and by selecting:
‘User Settings → Driver Assistance
→ Forward Safety’
- If you select "Active Assist", the FCA system activates. The FCA
produces warning messages
and warning alarms in accor-
dance with the collision risk lev-
els. Also, it controls the brakes in
accordance with the collision risk
levels.

Take the following precautions
when using the Forward Collision-
Avoidance Assist (FCA) system:
This system is only a supple-
mental system and it is not
intended to, nor does it replace
the need for 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. The Forward Collision-
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.

System Malfunction
Check Forward Collision Avoidance
Assist system
When the FCA is not workingproperly, the FCA warning light
( ) will illuminate and the warn-
ing message will appear for a few
seconds. After the message dis-
appears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized HYUNDAI dealer.
The FCA warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
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 prematurely. This ini-
tial 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.
WARNING If there is a malfunction with
the FCA system, the Forward
Collision avoidance assist
system is not applied even
though the braking system is
operating normally.
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.
The brake control may not
work, possibly causing a colli-
sion, if a vehicle in front
abruptly stops. Always pay
extreme caution.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian on the roadway through
radar signals and camera recogni-
tion 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
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.
The FCA system may not acti-
vate according to the road
conditions, inclement weath-
er, driving conditions or traffic
conditions.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system does not
detect all vehicles.
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.
WARNING

Driving your vehicle
Blind-Spot Collision-Avoidance Assist
(BCA) system is automatically deacti-
vated when:
- The vehicle drives a certain dis- tance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in
the middle of the vehicle lanes to
keep the system in the ready status.
When the vehicle drives too close to
one side of the vehicle lanes, the
system may not properly operate.
In addition, the system may not prop-
erly control your vehicle in accor-
dance with driving situations. Thus,
always pay close attention to road
situations.
Detecting Sensor
(Camera and Radar)

The driver is responsible for
accurate steering.
Do not unnecessarily operate
the steering wheel, when the
Blind-Spot Collision-Avoidance
Assist System is in operation.
Always pay extreme caution
while driving. The Blind-Spot
Collision-Avoidance Assist
system may not operate or
unnecessarily operate in
accordance with your driving
situations.
The Blind-Spot Collision-
Avoidance Assist system is
not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. Pay attention to the road
conditions at all times.
