Electronic Stability Control
(ESC)
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 man-
agement 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.
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 seconds
and goes off, then the ESC is turned
on.
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:

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.

engine may not respond to the
accelerator as it does under rou-
tine conditions.

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) 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.WARNING

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 shortly
(ESC OFF indicator light illumi-
nates). At this state, the engine con-
trol function does not operate. In
other words, the traction control
function does not operate but only
the brake control function operates.
Press the ESC OFF button for more
than 3 seconds. ESC OFF indicator
light illuminates and ESC OFF warn-
ing chime will sound. At this state,
the engine control function and brake
control function does not operate. In
other words, the vehicle stability con-
trol function does not operate any
more.
If the Engine Start/Stop button is
pressed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the engine, the ESC will
automatically turn on again.
Indicator lights
When the Engine Start/Stop button
is pressed to the ON position, the
ESC indicator light illuminates, then
goes off if the ESC system is operat-
ing 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.

Driving your vehicle
The ESC OFF indicator light comes
on when the ESC is turned off from
the User Settings Mode.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.
✽ ✽
NOTICE
Turning the ESC off does not affect
ABS or standard brake system oper-
ation.
When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER
attempt to accelerate. NEVER
turn the ESC off while the ESC
indicator light is blinking or you
may lose control of the vehicle
resulting in an accident.
WARNING
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires for this vehicle.
CAUTION
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) exces-
sively while these lights are
displayed.
When operating the vehicle
on a dynamometer, ensure the
ESC is turned off (ESC OFF
light illuminated).
CAUTION

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
prevents 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 when the accelerator
pedal is depressed or after 2 sec-
onds.
✽ ✽
NOTICE
• The HAC does not operate when
the 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. Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates 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 the P (Park)
position, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles with the parking brake
not fully engaged are at risk for
moving inadvertently and caus-
ing injury to yourself or others.

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 for the
road conditions or too quickly
when cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. AEB does not stop the
vehicle completely and does
not avoid collisions.
(Continued)
(Continued)
AEB operates according to
the distance from the vehicle
ahead, relative velocity, and
driver's operation of the brake
or accelerator pedal. Do not
drive dangerously to inten-
tionally operate the AEB.
ALWAYS check the speed and
the distance to the vehicle
ahead. The AEB is not a sub-
stitute for safe driving prac-
tices.
WARNING

AEB Operation
Warning message
A warning message and chime will
sound when you need to use the
brake pedal or steering wheel due to
a sudden stop or lack of distance
with the vehicle ahead. The warning
messages will vary according to the
severity of the situation. Immediately
reduce your speed to prevent a colli-
sion.Brake operation
In a critical situation:
The brake assist system enters
standby mode to react promptly
when the driver operates the brake
pedal.
The vehicle automatically reduces
speed according to the severity of
the situation.
- Rapidly reduces speed when vehi-
cle speed is under 50 mph (80
km/h)
- Slowly reduces speed when vehi-
cle speed is over 50 mph (80 km/h)
If the driver uses the brake pedal to
reduce vehicle speed, the brake
assist system operates to increase
braking efficiency.
If the driver presses down hard on
the accelerator pedal or sharply
turns the steering wheel, the brake
assist system is canceled.
Seat belt operation
The driver's and passenger's seat
belt may tighten if the system detects
that a vehicle or object is close.
