Driving your vehicle
Anti-lock brake system (ABS) The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergency
situation, do not attempt to modulate
your brake pressure and do not try to
pump your brakes. Press your brake
pedal as hard as possible or as hard
as the situation warrants and allow
the ABS to control the force being
delivered to the brakes.
WARNING
ABS (or ESC) will not prevent
accidents due to improper or
dangerous driving maneuvers.
Even though vehicle control is
improved during emergency
braking, always maintain a safe
distance between you and
objects ahead. Vehicle speeds
should always be reduced dur-
ing extreme road conditions.
The braking distance for vehi-
cles equipped with an anti-lock
braking system or (Electronic
Stability Control System) may be
longer than for those without it
in the following road conditions.
During these conditions the
vehicle should be driven at
reduced speeds:(Continued)
(Continued)
Rough, gravel or snow-cov-ered roads.
With tire chains installed.
On roads where the road sur- face is pitted or has different
surface height.
The safety features of an ABS
(or ESC) equipped vehicle
should not be tested by high
speed driving or cornering.
This could endanger the safe-
ty of yourself or others.

NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.
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.

✽
✽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.(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.CAUTION
When you drive on a road hav- ing poor traction, such as anicy road, and operate yourbrakes continuously, the ABSwill be active and the ABSwarning light may illuminate.Pull your vehicle over to a safeplace and 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.

Electronic stability control
(ESC)
The Electronic Stability Control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes at individual wheels and inter-
venes in the engine management
system to stabilize the vehicle. The Electronic Stability Control
(ESC) system is an electronic sys-
tem designed to help the driver main-
tain vehicle control under adverse
conditions. It is not a substitute for
safe driving practices. Factors includ-
ing speed, road conditions and driv-
er steering input can all affect
whether ESC will be effective in pre-
venting a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ESC is active.

WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. Electronic stability
control (ESC) will not prevent
accidents. Excessive speed in
turns, abrupt maneuvers and
hydroplaning on wet surfaces
can still result in serious acci-
dents. Only a safe and attentive
driver can prevent accidents by
avoiding maneuvers that cause
the vehicle to lose traction.
Even with ESC installed, always
follow all the normal precautions
for driving - including driving at
safe speeds for the conditions.

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 bank road such as gra-
dient 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.
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.

Driving your vehicle
✽
✽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)
(if equipped)
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 under approximately 6.3 mph
(10 km/h) and lets the driver concen-
trate 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)
(if equipped)
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.
✽ ✽ NOTICE
• The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not acti-
vate when the ESC has malfunc-
tioned.
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.
