Driving your vehicle
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.✽ ✽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.

Driving your vehicle
✽
✽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.
ODM052046
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 maneu-
vers, and hydroplaning on wet
surfaces can result in severe
accidents.

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 asgradient 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.
✽ ✽
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.

Driving your vehicle
✽
✽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.
Good braking practices
After being parked, check to be
sure the parking brake is not
engaged and that the parking
brake indicator light is out before
driving away. Driving through water may get the
brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! 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, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and call an authorized
HYUNDAI dealer for assistance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
WARNING
Whenever you leave or parkyour vehicle, always set the
parking brake as far as possi-
ble and fully engage the vehi-
cle's transaxle into the P (Park)
position. If the parking brake is
not fully engaged, the vehicle
may move inadvertently and
injure yourself and others.
All vehicles should always have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injure
occupants or pedestrians.
