Driving your vehicle
✽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 a
problem with the ABS. In this
case, however, your regular
brakes will work normally.

(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.

for approximately 3 sec-
onds, then ESC is turned
on.

ton for at least half a sec-
ond after turning the igni-

you may hear a slight tick-
ing sound. This is the ESC
performing an automatic
system self-check and

lem.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks.
• When the Electronic
Stability Control is operat-
ing properly, you can feel a
slight pulsation in the vehi-
cle. This is only the effect
of brake control and indi-
cates nothing unusual.
• When moving out of the
mud or slippery road, the
engine rpm (revolution per
minute) may not be
increased 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 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.

ECS controls the vehicle suspension
automatically to maximize passenger
comfort by using the air spring in the
suspension.
You can also control the vehicle sus-
pension manually in NORMAL mode
or HIGH mode.
To control the vehicle height
• Push the vehicle height control but-
ton to select the HIGH mode that
makes the vehicle height be higher
than the NORMAL mode and the
indicator light on the vehicle height
control button will illuminate. It is
useful in a rough road.
• Push the vehicle height control but-
ton again to select the NORMAL
mode that makes the vehicle
height lower than the HIGH mode.
The indicator light in the vehicle
height control button will go off.
• When the vehicle stops with the
shift lever in P(Park) or N(Neutral),
you may change the vehicle height.
• When you drive under 70km/h, you
may select the HIGH mode.
• If the vehicle speed exceeds
70km/h while driving in the HIGH
mode, the NORMAL mode will be
selected automatically.• If the vehicle speed exceeds
120km/h while driving in NORMAL
mode, the LOW mode that is lower
than NORMAL mode will be select-
ed automatically. LOW mode can
not be selected manually.
• When you drive under 80km/h in
the LOW mode, the NORMAL
mode will be selected automatical-
ly.
• When the engine start/stop button
is turned off with the HIGH mode
selected, the HIGH mode will be
maintained.
It is to prevent damage under the
vehicle when parked in rough
roads.
• The height of the vehicle may be
adjusted after the engine start/stop
button is turned off for 2 hours/
5 hours/10 hours.
It is to compensate vehicle height
affected by outside temperature.
