✽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.
W-78
CAUTION
• If the ABS warning light is on
and stays on, you may have a
problem with the ABS. In this
case, however, your regular
brakes will work normally.
(Continued)
(Continued)
• The ABS warning light will
stay on for approximately 3
seconds after the ignition
switch is ON. 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. Contact an authorized
HYUNDAI dealer as soon as
possible.

✽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 low battery voltage. It
does not mean your ABS has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC) (If equipped)
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 on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
CAUTION
• When you drive on a road hav-
ing poor traction, such as an
icy road, and have operated
your brakes continuously, the
ABS will be active continuous-
ly and the ABS warning light
may illuminate. Pull your vehi-
cle over to a safe place and
stop the engine.
• Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a
problem with the ABS.
Contact an authorized
HYUNDAI dealer as soon as
possible.

ESC OFF usage
When driving
• ESC should be turned on for daily
driving whenever possible.
• To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated and the buzzer beeps)
by pressing the button for 3 sec-
onds. If the ESC is left on, it may
prevent the vehicle speed from
increasing, and result in false diag-
nosis.
• Turning the ESC off does not
affect ABS or brake system opera-
tion. CAUTION
Driving with varying tire or
wheel sizes may cause the ESC
system to malfunction. When
replacing tires, make sure they
are the same size as your origi-
nal tires.
WARNING
The Electronic Stability Control
is only a driving aid; use pre-
cautions for safe driving by
slowing down on curved,
snowy, or icy roads. Drive slow-
ly and don’t attempt to acceler-
ate whenever the ESC indicator
light is blinking, or when the
road surface is slippery.
WARNING
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
CAUTION
Even if you cancel the ESC
function by pressing the button,
the ESC function may be operat-
ed. It is normal condition for
safety driving.

Hill-start assist control (HAC)
(if equipped)
A vehicle has the tendency to slip
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from slipping back by operat-
ing the brakes automatically for
about 2 seconds. The brakes are
released when the accelerator pedal
is depressed or after about 2 sec-
onds.
✽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.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop light when the vehicle is
braked rapidly and severely.
The system is activated when:
• The vehicle suddenly stops (vehi-
cle speed is over 55km/h and the
vehicle deceleration at greater
than 7 m/s
2)
• The ABS is activating
When the vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the
stop light blinking will stop. Instead,
the hazard warning flasher will turn
on automatically.
The hazard warning flasher will turn
off when vehicle speed is over
10km/h after the vehicle has
stopped. Also, it will turn off when the
vehicle is driven at low speed for
some time. You can turn it off manu-
ally by pushing the hazard warning
flasher switch.
WARNING
The HAC is activated only for
about 2 seconds, so when the
vehicle is starting off always
depress the accelerator pedal.

Good braking practices• Check to be sure the parking brake
is not engaged and that the park-
ing 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 car
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 car 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.CAUTION
The Emergency Stop Signal
(ESS) system will not work if the
hazard warning flasher is
already on.WARNING
• Whenever leaving vehicle or
parking, always set the park-
ing brake and fully engage the
vehicle's transmission into
the P (Park) position. Vehicles
not fully engaged in park with
the parking brake set are at
risk for moving inadvertently
and injuring yourself or oth-
ers.
• 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.

➀Cruise indicator ( )
➁SET indicator
The cruise control system allows you
to program the vehicle to maintain a
constant speed without pressing the
accelerator pedal.
This system is designed to function
above approximately 40 km/h (25
mph) and below approximately 180
km/h (113 mph).
✽NOTICE
During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
• If the cruise control is left on,
(cruise indicator light in the
instrument cluster illuminat-
ed) the cruise control can be
activated unintentionally.
Keep the cruise control sys-
tem off (cruise indicator light
off) when the cruise control is
not in use, to avoid inadver-
tently setting a speed.
• Use the cruise control system
only when traveling on open
highways in good weather.
• Do not use the cruise control
when it may not be safe to
keep the vehicle at a constant
speed, for instance, driving in
heavy or varying traffic, or on
slippery (rainy, icy or snow-
covered) or winding roads or
over 6% up-hill or down-hill
roads.
• Pay particular attention to the
driving conditions whenever
using the cruise control system.

• Be careful when driving
downhill using the cruise con-
trol system, which may
increase the vehicle speed.
