EPB malfunction indicator
(if equipped)
This warning light illuminates if the
Engine Start/Stop button is changed
to the ON position and goes off in
approximately 3 seconds if the sys-
tem is operating normally.
If the EPB malfunction indicator
remains on, comes on whilst driving,
or does not come on when the
Engine Start/Stop button is changed
to the ON position, this indicates that
the EPB may have malfunctioned.If this occurs, we recommend that
the system be checked by an autho-
rised HYUNDAI dealer.
The EPB malfunction indicator may
illuminate when the ESC indicator
comes on to indicate that the ESC is
not working properly, but it does not
indicate a malfunction of the EPB.• If the EPB warning light is still
on, we recommend that the sys-
tem be checked by an autho-
rised HYUNDAI dealer.
• If the parking brake warning
light does not illuminate or
blinks even though the EPB
switch was pulled up, the EPB
may not be applied.
• If the parking brake warning
light blinks when the EPB warn-
ing light is on, press the switch,
then pull it up. Then press it
back to its original position and
pull it back up. If the EPB warn-
ing does not go off, we recom-
mend that the system be
checked by an authorised

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilise the
vehicle during cornering manoeu-
vres.
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 ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately 3 seconds and goes off then
the ESC is turned on.
OLF054448R
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
manoeuvres, and hydroplaning
on wet surfaces can result in
severe accidents.

engine, the ESC will automatically
turn on again.Indicator lights
When the ignition switch is pressed
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.

mend that the vehicle be checked by
an authorised HYUNDAI dealer as
soon as possible.The ESC OFF indicator light comes
on when the ESC is turned off with
the button.

sizes may cause the ESC system
to malfunction. When replacing
tyres, make sure they are the
same size as your original tyres
for this vehicle.

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 whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.To prevent damage to the
transaxle:
• Do not allow wheel(s) of one
axle to spin excessively whilst
the ESC, ABS, and brake warn-
ing lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively whilst
these lights are displayed.
• When operating the vehicle on a
dynamometer, ensure the ESC is
turned off (ESC OFF light illumi-
nated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(if equipped)
Vehicle Stability Management (VSM)
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tyres can suddenly become uneven.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
•ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
•Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
