ESC operation
ESC ON condition
When the Engine Start/Stop button
is in the ON position, the ESC and
the ESC OFF indicator lights illumi-
nate for approximately three sec-
onds. After both lights go off, the
ESC is enabled.
When operating
When the ESC is in opera-
tion, 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 vehi- cle may not respond to the accel-
erator as it does under routine con-
ditions.
If the Cruise Control was in use when the ESC activates, the
Cruise Control automatically disen-
gages. The Cruise Control can be
reengaged when the road condi-
tions 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 sta-
bility and traction of the vehicle and
does not indicate a problem.
ESC OFF condition
To cancel ESC operation :
State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and
message will illuminate. In this state,
the traction control function of ESC
(engine management) is disabled,
but the brake control function of ESC
(braking management) still operates.
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.

Driving your vehicle

Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the Engine Start/Stop button is
placed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the vehicle, the ESC will
automatically turn on again.
Indicator lights
When the Engine Start/Stop button
is placed to the ON position, the ESC
indicator light illuminates, then goes
off if the ESC system is operating
normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off. Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.NOTICE

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
The HAC does not operate whenthe shift lever is in P (Park) or N
(Neutral).
The HAC activates even though the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
Good Braking Practices
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side. To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.
If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
NOTICE
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC activates
only for approximately 2 seconds.
WARNING
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into P (Park) posi-
tion, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles parked with the park-
ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

The Autonomous Emergency
Braking (AEB) system is designed to
help detect and monitor the vehicle
ahead or detect a pedestrian (if
equipped) in the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.System Setting and Activation
System setting
The driver can activate the AEB by
placing the Engine Start/Stop button
to the ON position and by selecting:
Cluster type A
'User Settings →Driving Assist →

Take the following precautions
when using the Autonomous
Emergency Braking (AEB):
This system is only a supple-
mental system and it is not
intended to, nor does it
replace the need for extreme
care and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at all
times.
NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and is not
a collision avoidance system.

Prerequisite for activation
The AEB system is on and ready
when AEB is selected on the LCD
display and when the following pre-
requisites are satisfied:
- The ESC (Electronic StabilityControl) is on.
- Driving speed exceeds approxi- mately 6 mph (10 km/h). (The AEB
is only activated within a certain
speed range.)
- The system detects a pedestrian or a vehicle in front, which may col-
lide with your vehicle. (The AEB
may not be activated or may sound
a warning alarm in accordance
with the driving situation or vehicle
condition.)
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.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 when the Engine Start/
Stop button is in the ON posi-
tion. The driver can deactivate
the AEB by canceling the sys-
tem setting on the LCD dis-
play.
If you cancel the ESC
(Electronic Stability Control)
when the AEB system is
turned on, the AEB automati-
cally deactivates and the AEB
warning light illuminates.
When the ESC is cancelled
the AEB cannot be activated
on the LCD display. The AEB
warning light will illuminate
which is normal.

LKAS Operation
To activate/deactivate the LKAS:
With the Engine Start/Stop button in
the ON position, press the LKAS but-
ton located on the instrument panel
on the left hand side of the steering
wheel. The indicator in the cluster
display will initially illuminate white.
This indicates the LKAS is in the
READY but NOT ENABLED state.
(Continued)
Always have your hands on
the steering wheel while the
LKAS system is activated. If
you continue to drive with
your hands off the steering
wheel after the "Keep hands
on steering wheel" warning
message appears, the system
will turn off automatically.
After then, if you drive with
your hands on the steering
wheel, the control will be acti-
vated again.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
speed when leaving a lane the
vehicle may not be able to be
controlled by the system. The
driver must always follow the
speed limit when using the
system.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly.
OAE056050L
(Continued)
The system detects lane
markers and controls the
steering wheel by a camera,
therefore, if the lane markers
are hard to detect, the system
may not work properly.
Please refer to "Limitations of
the system".
Do not remove or damage the
related parts of LKAS.
You may not hear a warning
sound of LKAS because of
excessive audio sound.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
