Driving your vehicle
The ISG system is to reduce the fuel
consumption by automatically shut-
ting down the engine, when the vehi-
cle 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 the hood are closed.
- The brake vacuum pressure is adequate.
- The battery is sufficiently charged.
- The outside temperature is between -10 °C and 35 °C (14 °F and 95 °F).
- The engine coolant temperature is not too low.
- The system is not in the diagnostic mode.
- The steering wheel is not steered excessively. (for dual clutch trans-
mission vehicle)
- The vehicle is driven on a steep incline. (for dual clutch transmis-
sion vehicle)
Information
• The ISG system is not activated,when the prerequisites to activate

The battery sensor deactiva-
tion
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 IGS
system.
- The battery is weak.
- The brake vacuum pressure is low.
In those cases, we recommend you to
have the ISG system checked by an
authorized HYUNDAI dealer. Use only the 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. If
not, it may damage or explode
the ISG battery.
Do not remove the battery cap. If not, the battery electrolyte,
which is harmful to the human
body, may leak out.

AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
Forward Warning (1stwarning)
This initial warning message appears
on the LCD display with a warning
chime.
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the AEB system.
The AEB automatically acti-
vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the AEB by canceling
the system setting on the LCD
display.
The AEB automatically deacti-
vates upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
the AEB cannot be activated
on the LCD display.

Collision Warning (2ndwarning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.- Your vehicle speed may deceler-ate moderately.
- The AEB system limitedly con- trols the brakes to preemptively
mitigate impact in a collision.
Emergency braking (3rdwarning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decel-
erate the vehicle.
- The AEB system limitedly con-trols the brakes to preemptively
mitigate impact in a collision. The
brake control is maximized just
before a collision.
Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The AEB 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 AEB brake control is automat- ically canceled, when risk factors
disappear.
OPDE056038
OPDE056037
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.

System malfunction
Check AEB system
When the AEB is not working prop-erly, the AEB warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case, we
recommend you to have the vehicle
inspected by an authorized
HYUNDAI dealer.
The AEB warning message may appear along with the illumination
of the ESC (Electronic Stability
Control) warning light.
The AEB 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 AEB
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 AEB 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 AEB system
may not activate and the
warning message will not be
displayed.
(Continued)
(Continued)
If there is a malfunction with the
AEB system, the autonomous
emergency braking is not
applied even though the brak-
ing system is operating normal-
ly.
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 AEB 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 AEB system may not acti-
vate if the driver applies the
brake pedal to avoid a colli-
sion.
The AEB system operates
only to detect vehicles or
pedestrians in front of the
vehicle.(Continued)

Limitations of the system
The Autonomous Emergency Braking
(AEB) system is designed to 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 brak-
ing.
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 AEB sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
AEB 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)
(Continued)
The AEB system does not
operate when the vehicle is in
reverse.
The AEB system is not
designed to detect other
objects on the road such as
animals.
The AEB system does not
detect vehicles in the oppo-
site lane.
The AEB system does not
detect cross traffic vehicles
that are approaching.
The AEB 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
maintain a safe braking dis-
tance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis-
tance.

5-86
Driving your vehicle
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
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 windshield glass is fogged up; a clear view of the road is obstruct-
ed
The vehicle in front is driving errat- ically
The vehicle drives through a con- struction area, on an unpaved
road, or above metal materials,
such as a railway
The vehicle drives inside a build- ing, such as a basement parking
lot
The adverse road conditions cause excessive vehicle vibrations while
driving - Driving on a curve
The performance of the AEB system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the AEB system may activate
prematurely.
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. The AEB system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
