(Continued)In these cases, the brake warning
light comes on, the AUTO HOLD
indicator changes from green to
white, and a warning sounds and a
message will appear to inform you
that EPB has been automatically
engaged. Before driving off again,
press foot brake pedal, check the
surrounding area near your vehi-
cle and release parking brake
manually with the EPB switch.
• If the AUTO HOLD indicator lights up yellow, the Auto Hold is
not working properly. Contact an
authorized HYUNDAI dealer.
• While operating Auto Hold, you may hear mechanical noise.
However, it is normal operating
noise.

Driving your vehicle
Even with the anti-lock brake sys-tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system.
CAUTION
If the ABS warning light is on and stays on, you may have aproblem with the ABS. In thiscase, however, your regularbrakes will work normally.
(Continued)
(Continued) The ABS warning light will stay on for approximately 3seconds after the ignitionswitch is ON. During that time,the ABS will go through self-diagnosis and the light will gooff if everything is normal. Ifthe light stays on, you mayhave a problem with yourABS. Contact an authorizedHYUNDAI dealer as soon aspossible.

NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
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 malfunc-
tioning.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
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.

CAUTION
When the brakes are operated
continuously on a road havingpoor traction, the ABS will beactive and the ABS warninglight may illuminate. Pull yourvehicle over to a safe placeand stop the engine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have aproblem with the ABS. Contactan authorized HYUNDAI dealeras soon as possible.

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 and goes off,
then the ESC is turned on.
If this light stays on, your vehicle may
have a malfunction with the ESC
system. Have your vehicle checked
by an authorized HYUNDAI dealer
as soon as possible.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
brakes under conditions
which may lock the
wheels, you may hear
sounds from the brakes, or
feel a corresponding sen-
sation in the brake pedal.
This is normal and it
means your ESC is active.

respond to the accelerator
as it does under routine
conditions.
in use when the ESC acti-
vates, the cruise control
automatically disengages.
The Cruise Control can be
reengaged when the road
conditions allow. See
"Cruise Control System"
later in this chapter.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 maneuvers, and
hydroplaning on wet surfaces
can result in severe accidents.

mud or driving on a slip-
pery 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 prob-
lem. ESC OFF condition
To cancel ESC operation :

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 ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically
turn on again.

affect ABS or standard brake sys-
tem operation.
Vehicle stability management
(VSM) (if equipped)
This system provides further
enhancements to vehicle stability
and steering responses when a vehi-
cle is driving on a slippery road or a
vehicle detected changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the VSM is in operation, ESC
indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS). This is only the effect of brake
and EPS control and indicates noth-
ing unusual. The VSM does not operate when:
Driving on a banked road such as
gradient or incline
Driving rearward
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to
turn off the ESC, the VSM will also
cancel and the ESC OFF indicator
light ( ) illuminates.
To turn on the VSM, press the button
again. The ESC OFF indicator light
goes out.
CAUTION
To prevent damage to thetransaxle:
Do not allow wheel(s) of one axle to spin excessively whilethe ESC, ABS, and brakewarning lights are displayed.The repairs would not be cov-ered by the vehicle warranty.Reduce engine power and donot spin the wheel(s) exces-sively while these lights aredisplayed.
When operating the vehicle on a dynamometer, ensure theESC is turned off (ESC OFFlight illuminated).

Malfunction indicator
The VSM system will automatically
be deactivated if a malfunction has
been detected somewhere in the
Electric Power Steering system or
the VSM system. If a malfunction is
detected, the ESC indicator light will
illuminate and remain on. If the ESC
indicator light ( ) or EPS warning
light remains on, take your vehicle to
an authorized HYUNDAI dealer and
have the system checked.
✽ ✽NOTICE
• The VSM is designed to function
above approximately 9 mph (15
km/h) on curves.
• The VSM is designed to function above approximately 18 mph (30
km/h) when a vehicle is braking on
a split-mu road. The split-mu road
is made of surfaces which have dif-
ferent friction forces.
Downhill brake control (DBC)
The Downhill Brake Control (DBC)
assists the driver when descending a
steep hill without the driver depress-
ing the brake pedal. It slows the vehi-
cle to approximately 6.3 mph (10
km/h) and lets the driver concentrate
on steering the vehicle.
DBC defaults to the OFF position
whenever the ignition is turned on.
The DBC can be turned on or off by
pushing the button.
WARNING
The Vehicle Stability
Management system is not a
substitute for safe driving
practices but a supplemen-
tary function only. It is the
responsibility of the driver to
always check the speed and
the distance to the vehicle
ahead. Always hold the steer-
ing wheel firmly while driving.
Your vehicle is designed to operate according to the dri-
ver's input through steering,
acceleration, and braking,
even with the VSM opera-
tional. Always follow all the
normal precautions for driv-
ing at safe speeds for the con-
ditions – including driving in
inclement weather and on a
slippery road.
Driving with varying tire or wheel sizes may cause the
VSM system to malfunction.
When replacing tires, make
sure they are the same size as
your original tires.

✽NOTICE
• The DBC does not turn ON in the
P (Park) position.
• The DBC may not activate if the ESC (or ABS) is activated.
• Noise or vibration may occur from the brakes when the DBC is acti-
vated.
• The rear stop light comes on when the DBC is activated.
• Always turn OFF the DBC on nor- mal roads. The DBC might acti-
vate from the standby mode dur-
ing abrupt cornering or driving
over speed bumps.
Hill-start assist control (HAC)
A vehicle has the tendency to roll
back on a steep hill when the driver
begins to accelerate after a stop. The
Hill-start Assist Control (HAC) pre-
vents the vehicle from rolling back by
operating the brakes automatically
for about 1.5 seconds. The brakes
are released when the accelerator
pedal is depressed or after about 1.5
seconds.WARNING
Unnecessary or unwanted
DBC activation may result in
an accident.
On a very steep hill even though the brake pedal or
accelerator pedal is depressed
the DBC may not deactivate.
WARNING
The HAC is activated only for
about 1.5 seconds, so always
depress the accelerator pedal to
begin accelerating after a stop.
