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 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.

Non-operational conditions ofParking Assist System
The Rear Parking Assist System
may not operate normally when:
Moisture is frozen to the sensor.
The sensor is covered with dirt or debris such as snow or ice, or the
sensor cover is blocked.
There is a possibility of the Rear
Parking Assist System malfunction
when:
Driving on uneven road surfacessuch as unpaved roads, gravel,
bumps, or gradient.
Objects generating excessive noise such as vehicle horns, loud
motorcycle engines, or truck air
brakes can interfere with the sen-
sor.
Heavy rain or water spray is pres- ent.
Wireless transmitters or mobile phones are present near the sen-
sor.
The sensor is covered with snow.
Any non-factory equipment or accessories have been installed,
or if the vehicle bumper height orsensor installation has been modi-fied.
Detecting range may decrease
when:
Outside air temperature isextremely hot or cold.
Undetectable objects smaller than 1 m (40 inches) and narrower than
14 cm (6 inches) in diameter.
The following objects may not be
recognized by the sensor:
Sharp or slim objects such asropes, chains or small poles.
Objects, which tend to absorb sen- sor frequency such as clothes,
spongy material or snow.

Driving your vehicle
The AEB is only a supplemen-
tal system for the driver’s con-
venience. The driver shouldhold 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 brakepedal to reduce the drivingspeed.
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 automat-
ic emergency braking is not
applied even though the brak-ing system is operating nor-
mally.
The AEB system operates
only to help detect vehicles or
pedestrians in front of the
vehicle. 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 asanimals. 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 deadend street.)(Continued)
(Continued)
In these cases, you must
maintain a safe braking dis-
tance, and if necessary,depress the brake pedal toreduce the driving speed in
order to maintain a safe dis-
tance.WARNING

- 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.
- Driving on a slope
The performance of the AEB
decreases while driving upward or
downward on a slope, not recogniz-
ing the vehicle in front in the same
lane. It may unnecessarily produce
the warning message and the warn-
ing alarm, or it may not produce the
warning message and the warning
alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain distance.

In traffic situation
In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also, if
the vehicle ahead of you starts mov-
ing, your vehicle will start as well.
However, if the vehicle stops for
more than 3 seconds, you must
depress the accelerator pedal or
push up the toggle switch (RES+ or
SET-) to start driving.
SCC front radar sensor
The Smart Cruise Control uses a
radar to detect distance to the vehi-cle ahead.
OLF057203N
OLF057204N
If the vehicle ahead (vehicle
speed: less than 30 km/h (20
mph)) disappears to the next
lane, the warning chime will
sound and a message will
appear. Adjust your vehicle
speed for vehicles or objects
that can suddenly appear in
front of you by depressing thebrake pedal.
Always pay attention to the road condition ahead.

Limitations of the system
The Smart Cruise Control System
may have limits to its ability to detect
distance to the vehicle ahead due to
road and traffic conditions.
On curves
The Smart Cruise Control Systemmay not detect a moving vehicle in
your lane, and then your vehicle
could accelerate to the set speed.
Also, the vehicle speed will
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on curves and apply the brakes or
accelerator pedal if necessary.

(Continued)
If the front bumper becomes
damaged in the area around
the radar sensor, the Smart
Cruise Control System may
not operate properly. Have the
vehicle inspected by an
authorized HYUNDAI dealer.
Use only genuine HYUNDAI
parts to repair or replace a
damaged sensor or sensor
cover. Do not apply paint to
the sensor cover.
