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 addition-
al benefit, and thus the SRS may
not deploy any air bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehi-
cle causing it to "ride" under a vehi-
cle with a higher ground clearance.
Air bags may not inflate in this
"under-ride" situation because
forces that are detected by sensors
may be reduced by such "under-
ride" collisions. Front air bags may not inflate in
rollover accidents where the
SRSCM indicates that the SRSCM
indicates that the front air bag
deployment would not provide
additional occupant protection.

If you desire to deactivate the rear
parking assist system, press the
rear parking assist OFF button
again. (The indicator on the button
will illuminate.) To turn the system
on, press the button again. (The
indicator on the button will go off.)
This system will activate when backing up with the ignition switch
ON.
If the vehicle is moving at a speed
over 6 mph (10 km/h), the system
will be deactivated.
The sensing distance while the rear parking assist system is in
operation is approximately 47 in.
(120 cm).
When more than two objects are sensed at the same time, the clos-
est object will be recognized first. Types of warning sound
When an object is 47 in. to 24 in.
(120 cm to 61 cm) from the rear
bumper: Buzzer beeps intermit-
tently.
When an object is 23 in. to 12 in. (60 cm to 31 cm) from the rear
bumper: Buzzer beeps more fre-
quently.
When an object is within 11.8 in. (30 cm) of the rear bumper:
Buzzer sounds continuously.Non-operational conditions of
rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will operate normally when the
moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or
the sensor cover is blocked. (It will
operate normally when the materi-
al is removed or the sensor is no
longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps,
gradient).
4. Objects generating excessive noise (vehicle horns, loud motor-
cycle engines, or truck air brakes)
are within range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the
sensor.
7. Trailer towing.

System malfunction
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 occurs,
have the vehicle inspected by an
authorized HYUNDAI dealer.
The AEB warning message may appear along with the illumination
of the ESC warning light.
ODM046661L
WARNING
The AEB is only a supplemen-tal system for the driver's con-
venience. The driver still
maintains responsibility to
control the vehicle. Do not
solely depend on the AEB
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to lower the driving
speed.
The AEB may unnecessarily produce warning messages
and warning alarms. Due to
sensor limitations, the AEB
may not produce warning
messages or the warning
alarm at all.
When there is a malfunction with the AEB, the braking con-
trol does not operate upon
detecting a collision risk even
with other braking systems
normally operating.
(Continued)
(Continued)
The AEB operates only for thevehicle / pedestrian in front,
while driving forward. It does
not operate for any animals or
vehicles in the opposite direc-
tion.
The AEB can not recognize the side-profile of vehicles,
such as in the case of cross-
traffic at an intersection, or a
vehicle pulling out of a drive-
way.

Limitation of the system
The AEB monitors driving conditions
through the radar and the camera
sensor. For any vehicle activity
occurring outside the sensor's range
and field of view, the AEB may not be
able to react. The driver should exer-
cise caution in the following situa-
tions, as the AEB operation may be
limited:
Recognizing vehicles
- The radar or the camera isobscured by foreign substances.
- In heavy rain or snow
- There is electromagnetic interfer- ence.
- The object in front deflects the radar beam due to extreme angles
or an extremely irregular surface.
- The vehicle in front has a narrow body. (i.e. motor cycle and bicycle)
- The sysem cannot identify objects in front due to driving into the at
dusk/dawn, bright reflections, or
darkness. - The camera cannot fit the full out-
line of a vehicle in front.
- The vehicle in front has cargo extending beyond the back of the
vehicle or has a high ground clear-
ance.
- The vehicle in front does not turn ON the rear lights, does not have
rear lights, has asymmetric rear
lights, or has rear lights out of
angle.
- Outside brightness changes sud- dently, such as entering/exiting a
tunnel.
- Vehicle driving is erratic.
- The radar/camera sensor recogni- tion is limited. - Driving on a curve
The AEB performance decreases
while driving on a curve. The AEB
may not recognize vehicles in front
that are in the same lane. It may
unnecessarily produce the warning
message and the warning alarm for
vehicles in a different lane, or it may
not produce the warning message
and the warning alarm at all.
While driving on a curve, exercise
caution, and, if necessary, depress
the brake pedal.

Driving your vehicle
In traffic situation
In traffic, your vehicle will stop if thevehicle 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+) to start driving.
If you push the advanced smart cruise control toggle switch (RES+
or SET-) while Auto Hold and
advanced smart cruise control is
operating (The green AUTO HOLD
indicator), Auto Hold will be
released regardless of accelerator
pedal operation and the vehicle will
start to move.
Sensor to detect distance to
the vehicle ahead
The Smart Cruise Control uses a
sensor to detect distance to the vehi-
cle ahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to
vehicle distance control may not
operate correctly.
Always keep the area in front of the
sensor clean.

On inclines
During uphill or downhill driving,
the Smart Cruise Control System
may not detect a moving vehicle in
your lane, and cause your vehicle
to accelerate to the original set
speed. Also, the vehicle speed will
rapidly decrease when the vehicle
ahead is recognized suddenly.
Select the appropriate set speed on inclines and apply the brake or
accelerator pedal if necessary.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme- diately 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 recognized by the sensor such
as:
- 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 loads
