If the parking brake does not release
or does not release all the way, have
the system checked by an authorized
HYUNDAI dealer.Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will be
illuminated when the parking brake is
applied with the ignition switch in the
START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while engine is running, there may be
a malfunction in the brake system.
Immediate attention is necessary.
WARNING
To prevent unintentionalmovement when stopped and
leaving the vehicle, do not use
the gearshift lever in place of
the parking brake. Set the
parking brake AND make sure
the gearshift lever is securely
positioned in P (Park) for
automatic transaxle equipped
vehicles.
Never allow anyone who is unfamiliar with the vehicle to
touch the parking brake. If the
parking brake is released
unintentionally, serious injury
may occur.
(Continued)

All vehicles should alwayshave the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injure
occupants or pedestrians.

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.

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.

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.
