Electronic Stability Control (ESC)
ODN8069018ODN8069018
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies
braking pressure to any one of the
vehicle's brakes and intervenes in the
engine management system to assist the
driver with keeping the vehicle on the
intended path. It is not a substitute for
safe driving practices. Always adjust your
speed and driving to the road conditions.
WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on wet
surfaces can result in severe accidents.
ESC operation
ESC ON condition
When the ignition switch is in the
ON position, the ESC and the ESC
OFF indica
tor lights illuminate for
approximately three seconds. After both
lights go off, the ESC is enabled.
When operating
When the ESC is in operation,
the ESC indicator light blinks:
• When you apply your brakes under conditions which may lock the wheels,
you may hear sounds from the brakes,
or feel a corresponding sensation in
the brake pedal. This is normal and it
means your ESC is active.
• When the ESC activates, the engine may not respond to the accelerator as
it does under routine conditions.
• If the Cruise Control was in use when the ESC activates, the Cruise Control
automatically disengages. The Cruise
Control can be reengaged when the
road conditions allow. See "Cruise
Control System" later in this chapter.
(if equipped)
• When moving out of the mud or driving on a slippery road, the engine
RPM (revolutions per minute) may
not increase even if you press the
accelerator pedal deeply. This is to
maintain the stability and traction of
the vehicle and does not indicate a
problem.

FCA system may work when it
recognizes objects similar in shape or
property to a vehicle, pedestrian or
cyclist.
FCA system is designed to help detect
and monitor the vehicle ahead or detect
a pedestrian or cyclist in the roadway
through radar signals and camera
recognition. It is not designed to detect
bicycles, motorcycles, or smaller
wheeled objects such as luggage bags,
shopping carts, or strollers.
Never try to test the operation of FCA
system. Doing so may cause severe
injury or death.
If the front bumper, front glass, radar or
camera have been replaced or repaired,
have the vehicle inspected by an
authorized HYUNDAI dealer.
Information
In some instances, FCA system
may be cancelled when subjected to
electromagnetic interference.
Information
This device complies with Part 15 of the
FCC rules.
Operation is subject to the following two
conditions:
1. This device may not cause harmful
interference.
2. This device must accept any
interference received, including
interference that may cause undesired
operation.
Forward Collision-Avoidance
Assist - Junction Turning (if
equipped)
FCA-Junction Turning function is
designed to reduce the risk of collision
by detecting and monitoring the
oncoming vehicle ahead. When the
vehicle turns to the left at a junction, the
system recognises the oncoming vehicle
ahead in advance with the front view
camera and the front radar. It produces
warning messages or haptic warning
alarms in accordance with the collision
risk levels.
System setting
FCA-Junction Turning function can be
activated from the User Settings menu
by following the procedure below.
1. Set the Engine Start/Stop button to the
ON or START position.
2. Select ‘User settings
 Driver
assistance  Forward safety’.
For more details, refer to “Forward
Collision-Avoidance Assist (FCA)” in this
chapter.

While Driving6-58
Limitations of the system
FCA-Junction Turning function is only a
supplemental system for driver’s safety
whilst turning left on the crossroads. The
driver should hold the responsibility to
control the vehicle. The system monitors
the oncoming vehicle ahead the road
through the front view camera and
radar. In certain situations, the front view
camera and radar may not be able to
detect the oncoming vehicles properly.
The driver must pay careful attention
in the following situations where the
system operation may be limited or it
may activate unintentionally.
The sensor may be limited when:
• The radar sensor or camera r
ecognizes the approaching vehicle
too late.
• The radar sensor or camera is blocked with a foreign object or debris.
• The driving direction of the approaching vehicle is irregular or
frontal.
• The approaching vehicle changes lanes too late or decelerates suddenly.
• The angle of the approaching vehicle is out of range.
• Whilst circling, the sensor (the front view camera or front radar) does not
detect the approaching vehicle.
• The driving speed of the approaching vehicle is too fast or slow.
• The head lamps of the approaching vehicle are turned off or asymmetrical. • The approaching vehicle stops whilst
turning left.
• The vehicle moves out of its lane or returns to its lane.
• The vehicle changes lanes suddenly at a low speed whilst there is an
approaching vehicle.
• The brightness outside is too so it does not detect the vehicle.
• Inclement weather such as heavy rain or snow obscures the field of view of
the front view camera or front radar.
• The approaching vehicle is covered with snow.
• The field of view in front is obstructed by sun glare.
• The shape of approaching vehicle is unusual.
• Whilst driving upward or downward on a slope.
For more information, refer to “Forward
Collision-Avoidance Assist (FCA)” in this
chapter.
