Driving your vehicle
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing 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 sys-
tem 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 igni-
tion switch is in the ON position.
During that time, the 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. We recom-
mend that you contact a HYUNDAI
authorised repairer as soon as pos-
sible. When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car 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 prob-
lem with your ABS system. We
recommend that you contact a
HYUNDAI authorised repairer as
soon as possible.
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.
i
NOTICE
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, we recommend
that you contact your HYUNDAI
authorised repairer as soon as
possible.

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize 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 three seconds. After both
lights go off, the ESC is enabled.

■
Type A
■Type B
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.
WARNING

5-34
Driving your vehicle
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.
cle may not respond to the acceler-
ator as it does under routine condi-
tions.
when the ESC activates, the Cruise
Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow. See "Cruise Control System"
later in this chapter. (if equipped)
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 stability and traction
of the vehicle and does not indicate
a problem.
ESC OFF condition
To cancel ESC operation :

Press the ESC OFF button briefly.
The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction & Stability
Control disabled" 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 ignition switch is placed in the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
vehicle, the ESC will automatically
turn on again.

Driving your vehicle
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle to spin excessively whilst the
ESC, ABS, and parking brake
warning 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, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
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.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control(ESC) is on.
Vehicle speed is approximately above 9 mph (15 km/h) on curve
roads.
Vehicle speed is approximately above 12 mph (20 km/h) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
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 substi-
tute for safe driving practices.
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.

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. If the braking action does
not return to normal, stop as soon as
it is safe to do so and we recommend
that you call a HYUNDAI authorised
repairer 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 tyre goes flat whilst you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead whilst 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.
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 ignition
switch in the LOCK/OFF posi-
tion.
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.

dition.)
FCA warning message and
system control
The FCA 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 FCA system.
The FCA automatically acti-
vates when the ignition switch
is in the ON position. The driv-
er can deactivate the FCA by
