Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your brake
pressure and do not try to pump your
brakes. Depress your brake pedal as hard as possible.
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 ABS is active.
ABS does not reduce the time or distance
it takes to stop the vehicle.
Always maintain a safe distance from the
vehicle in front of you.
ABS will not prevent a skid that results
from sudden changes in direction, such
as trying to take a corner too fast or
making a sudden lane change. Always
drive at a safe speed for the road and
weather conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering wheel
movement can still cause your vehicle to
veer into oncoming traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping distance
than for vehicles equipped with a
conventional brake system. The ABS (
) warning light will stay on
for several seconds after the Start/Stop
button is in the ON position.
During that time, ABS will go through
self-diagnosis and the light will go off if
everything is normal. If the light stays on,
you may have a problem with your ABS.
Contact an authorized HYUNDAI dealer as soon as possible.
WARNING
If the ABS (
) warning light is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your authorized
HYUNDAI dealer as soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, ABS will be
active continuously and the ABS (
)
warning light may illuminate. Pull your
vehicle over to a safe place and turn the
vehicle off.
Restart the vehicle. If the ABS warning
light is off, then your ABS system is normal.
Otherwise, you may have a problem
with your ABS system. Contact an
authorized HYUNDAI dealer as soon as possible.

06
6-37
Information
When you jump start your vehicle because
of a drained battery, the ABS (
)
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your ABS is malfunctioning. Have the battery
recharged before driving the vehicle.
Electronic Stability Control (ESC)
ONE1061020
Electronic Stability Control 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
electric vehicle control 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 when cornering. ESC 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 Start/Stop button is in the ON
position, ESC and the ESC OFF indicator
lights illuminate for approximately three
seconds. After both lights go off, ESC is enabled.
When operating
When 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 ESC activates, the vehicle may
not respond to the accelerator as it
does under routine conditions.
• If Cruise Control was in use when ESC
activates, Cruise Control automatically
disengages. Cruise Control can be
reengaged when the road conditions
allow. See “Cruise Control System”
section in chapter 7 (if equipped).

ESC OFF condition
To cancel ESC operation:
• State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and/or
message 'Traction Control disabled'
will illuminate. In this state, the traction
control function of ESC (electric vehicle
control management) is disabled, but the
brake control function of ESC (braking
management) still operates. • State 2
Press and hold the ESC OFF button
continuously for more than 3 seconds.
The ESC OFF indicator light and/or
message 'Traction & Stability Control
disabled' illuminates and a warning
chime sounds. In this state, both the
traction control function of ESC (electric
vehicle control management) and the
brake control function of ESC (braking
management) are disabled.
If the Start/Stop button is pressed to
the OFF position when ESC is off, ESC
remains off. Upon restarting the vehicle,
ESC will automatically turn on again.
When ESC (electric vehicle control) is
deactivated, the vehicle will loose the
traction and stability if the vehicle is
driven by abrupt steering wheel control.
It is possible that the tire may make a
collision with the connected parts of the
tire. We recommend to do not turn off
ESC while driving the vehicle for your
safety.
Indicator lights
■ ESC indicator light (blinks)

light illuminates, then goes off if the ESC
system is operating normally.

vehicle may have a malfunction with
the ESC system. When this warning light
illuminates , have the vehicle checked by
an authorized HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
when ESC is turned off.
WARNING
When ESC is blinking, this indicates ESC
is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn ESC off while
the ESC indicator light is blinking or you
may lose control of the vehicle resulting
in an accident.

NOTICE
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. 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 ESC, to maintain wheel
torque.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the reduction gear: • Do not allow wheel(s) of one axle to
spin excessively while the ESC, ABS,
and Parking Brake warning lights
are displayed. The repairs would not
be covered by the vehicle warranty.
Reduce motor power and do not spin
the wheel(s) excessively while these
lights are displayed.
• When operating the vehicle
on a dynamometer, make sure
ESC is turned off (ESC OFF light
illuminated).
Information
• Turning ESC off does not affect ABS or standard brake system operation.
• Select 0 step of the regenerative
braking system and depress the brake
pedal around 10 times to efficiently apply brake disc cleaning.
Brake disc cleaning may decrease the
driving distance by restraining the
regenerative braking system. After
brake disc cleaning, the regenerative
braking system may be restored.
If the regenerative braking system
is not restored after the brake disc cleaning, have the vehicle inspected by
an authorized HYUNDAI dealer.
