(ABS) or an Electronic Stability
Control (ESC) system will not pre-
vent accidents due to improper or
dangerous driving manoeuvres.
Even though vehicle control is
improved during emergency brak-
ing, always maintain a safe dis-
tance between you and objects
ahead of you. Vehicle speeds
should always be reduced during
extreme road conditions. The brak-
ing distance for vehicles equipped
with ABS or ESC may be longer
than for those without these sys-
tems in the following road condi-
tions.
Drive your vehicle at reduced
speeds during the following condi-

brakes will work normally. To
reduce the risk of serious injury or
death, we recommend that you

poor traction, such as an icy road,
and apply your brakes continuous-
ly, the ABS will be active continu-
ously and the ABS warning light
(

vehicle over to a safe place and
turn the engine off.
Restart the engine. If the ABS
warning light is off, then your ABS
system is normal.

ommend that you contact a
HYUNDAI authorised repairer as
soon as possible.
i Information

Electronic Stability Control

„7\ S H  %
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle
during cornering manoeuvres.
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 inter-
venes in the engine management
system to assist the driver with keep-
ing the vehicle on the intended path.
It is not a substitute for safe driving
SUDFWLFHV $OZD\V DGMXVW \RXU VSHHG
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
manoeuvres, and hydroplaning on
wet surfaces can result in severe
accidents.

When the ignition switch is in the ON
position, the ESC indicator light illu-
minates, then goes off if the ESC sys-
tem is operating normally.

ever the ESC is operating.

your vehicle may have a malfunction
with the ESC system. When this
warning light illuminates we recom-
mend that the vehicle be checked by
a HYUNDAI authorised repairer as
soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off with

to accelerate. NEVER turn the ESC
off whilst the ESC indicator light is
blinking or you may lose control of
the vehicle resulting in an acci-
dent.
