Battery Sensor Deactivation
OCN7060158N
[A] : Battery sensor
The battery sensor is deactivated, when 
the battery is disconnected from the 
negative pole for maintenance purpose. 
In this case, the ISG system is limitedly 
operated due to the battery sensor 
deactivation. Thus, the driver needs 
to take the following procedures to 
reactivate the battery sensor after 
disconnecting the battery. 
Prerequisites to reactivate the 
battery sensor
Switch "ON" and "OFF" the ignition one 
time. Park the vehicle for a minimum of 4 
hours with the hood and all doors closed.
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 reactivated.
 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 pressur
e is low. 
If this occurs, have the ISG system 
checked by an authorized HYUNDAI 
dealer.
NOTICE
•	 Use only a genuine HYUNDAI 
Absorbent Glass Mat (AGM) battery 
for replacement. If not, the ISG 
system may not operate normally.
•	 Do not recharge the Absorbent Glass 
Mat (AGM) battery with a general 
battery charger. It may damage or 
explode the Absorbent Glass Mat 
(AGM) battery. 
•	 Do not remove the battery cap. The 
battery electrolyte, which is harmful 
to the human body, may leak out.

Driver assistance system
7-2
Basic function
OCN7C070051
Forward Collision-Avoidance Assist is 
designed to help detect and monitor the 
vehicle ahead or detect a pedestrian in 
the roadway and warn the driver that 
a collision is imminent with a warning 
message and audible warning, and if 
necessary, apply emergency braking.
Detecting sensor
OCN7060030[1] : Front view camera
Refer to the picture above for the 
detailed location of the detecting sensor.
 CAUTION
Take the following precautions to 
maintain optimal performance of the 
detecting sensor:
•	NEVER disassemble the detecting 
sensor or sensor assembly, or apply 
any impact on it.
•	 If the detecting sensor have been 
replaced or repaired, we recommend 
that you have your vehicle inspected 
by an authorized HYUNDAI dealer.
•	 NEVER install any accessories or 
stickers on the front windshield, or 
tint the front windshield.
•	 Pay extreme caution to keep the 
front view camera dry.
•	 NEVER place any reflective objects 
(i.e. white paper, mirror) over the 
dashboard. Any light reflection may 
prevent the system from functioning 
properly.

OCN7070032L
When the front windshield where the 
front view camera is located or the 
sensor is covered with foreign material, 
such as snow or rain, it can reduce the 
detecting performance and temporarily 
limit or disable Forward Collision-
Avoidance Assist.
If this occurs the ‘Forward Safety system 
disabled.	Camera	obscured’	warning	
message, and the 
 and  warning 
lights will illuminate on the cluster.
The system will operate normally when 
such snow, rain or foreign material is 
removed.
If the system does not operate normally 
after obstruction (snow, rain, or foreign 
material) is removed, we recommend 
that the system be inspected by an 
authorized HYUNDAI dealer.
 WARNING
•	 Even though the warning message or 
warning light does not appear on the 
cluster, Forward Collision-Avoidance 
Assist may not properly operate. 
•	 Forward Collision-Avoidance Assist 
may not properly operate in an 
area (e.g. open terrain), where any 
substance are not detected after 
turning ON the engine.
Limitations of the function
Forward Collision-Avoidance Assist may 
not operate normally, OR the function 
may operate unexpectedly under the 
following circumstances:
•	The detecting sensor or the 
surroundings are contaminated or 
damaged
•	 The temperature around the front 
view camera is high or low
•	 The camera lens is contaminated due 
to tinted, filmed or coated windshield, 
damaged glass, or stuck of foreign 
material (sticker, bug, etc.) on the 
glass
•	 Moisture is not removed or frozen on 
the windshield
•	 Washer fluid is continuously sprayed, 
or the wiper is on
•	 Driving in heavy rain or snow, or thick 
fog
•	 The field of view of the front view 
camera is obstructed by sun glare 
•	 Street light or light from an oncoming 
vehicle is reflected on the wet road 
surface, such as a puddle on the road 
•	 An object is placed on the dashboard
•	 Your vehicle is being towed
•	 The surrounding is very bright
•	 The surrounding is very dark, such as 
in a tunnel, etc.
•	 The brightness changes suddenly, for 
example when entering or exiting a 
tunnel
•	 The brightness outside is low, and the 
headlamps are not on or are not bright

•	There is a group of pedestrians or a 
large crowd in front
•	 The pedestrian is wearing clothing 
that easily blends into the 
background, making it difficult to 
detect
•	 The pedestrian is difficult to 
distinguish from the similar shaped 
structure in the surroundings 
•	 You are driving by a pedestrian, 
traffic sign, structure, etc. near the 
intersection
•	 Driving in a parking lot
•	 Driving through a tollgate, 
construction area, unpaved road, 
partial paved road, uneven road, 
speed bumps, etc.
•	 Driving on an incline road, curved 
road, etc.
•	 Driving through a roadside with trees 
or streetlights
•	 The adverse road conditions cause 
excessive vehicle vibrations while 
driving
•	 Your vehicle height is low or high 
due to heavy loads, abnormal tire 
pressure, etc.
•	 Driving through a narrow road where 
trees or grass or overgrown
•	 There is interference by 
electromagnetic waves such as 
driving in an area with strong radio 
waves or electrical noise WARNING
•	Driving on a curve
OADAS003OADAS002
Forward Collision-Avoidance Assist 
may not detect other vehicles 
or pedestrians in front of you on 
curved roads adversely affecting the 
performance of the sensors. This may 
result in no warning or braking assist 
when necessary. 
When driving on a curve, you must 
maintain a safe braking distance, 
and if necessary, steer the vehicle 
and depress the brake pedal to 
reduce your driving speed in order to 
maintain a safe distance.

OADAS006OADAS005
Forward Collision-Avoidance Assist 
may detect a vehicle or pedestrian 
in the next lane or outside the lane 
when driving on a curved road. 
If this occurs, the system may 
unnecessarily warn the driver and 
control the brake. Always check the 
traffic conditions around the vehicle.•	
Driving on a slopeOADAS009
OADAS007
Forward Collision-Avoidance Assist 
may not detect other vehicles or 
pedestrians in front of you while 
driving uphill or downhill adversely 
affecting the performance of the 
sensors.
This may result in unnecessary 
warning or braking assist, or no 
warning or braking assist when 
necessary.
Also, vehicle speed may rapidly 
decrease when a vehicle or 
pedestrian ahead is suddenly 
detected. 
Always have your eyes on the road 
while driving uphill or downhill and 
if necessary, steer the vehicle and 
depress the brake pedal to reduce 
your driving speed in order to 
maintain a safe distance.
