Driving your vehicle
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BRAKE SYSTEM
(Continued)
To dry the brakes, apply them
lightly while maintaining a
safe forward speed until brake
performance returns to nor-
mal.
• Always, confirm the position
of the brake and accelerator
pedal before driving. If you
don't check the position of the
accelerator and brake pedal
before driving, you may
depress the accelerator
instead of the brake pedal. It
may cause a serious accident.WARNING- Brakes
• Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
• When descending a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Continuous
brake application will cause
the brakes to overheat and
could result in a temporary
loss of braking performance.
• Wet brakes may impair the
vehicle’s ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water.

In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
WARNING - Parking
brake
Applying the parking brake
while the vehicle is moving at
normal speeds can cause a
sudden loss of control of the
vehicle. If you must use the
parking brake to stop the vehi-
cle, use great caution in apply-
ing the brake.
WARNING - Brake wear
This brake wear warning sound
means your vehicle needs serv-
ice. If you ignore this audible
warning, you will eventually
lose braking performance,
which could lead to a serious
accident.
CAUTION
• To avoid costly brake repairs,
do not continue to drive with
worn brake pads.
• Always replace brake pads as
complete front or rear axle
sets.

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 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 vehicle
equipped with an anti-lock brak-
ing system (or Electronic
Stability Control) may be longer
than for those without it in the
following road conditions.
During these conditions the
vehicle should be driven at
reduced speeds:
• Rough, gravel or snow-cov-
ered roads.
• With tire chains installed.
(Continued)
(Continued)
• 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 safety of
yourself or others.

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.
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.

Driving your 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.✽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 Electronic
Stability Control System is func-
tioning properly. WARNING
Never drive too fast according
to the road conditions or too
quickly when cornering.
Electronic Stability Control
(ESC) will not prevent acci-
dents. 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 precau-
tions for driving - including driv-
ing at safe speeds for the condi-
tions.

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.

Driving your vehicle
• Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the car 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.
• If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the car pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.• If your vehicle is equipped with an
automatic transmission, don't let
your car creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake
and place the shift lever in P. If your
vehicle is facing downhill, turn the
front wheels into the curb to help
keep the vehicle from rolling. If
your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.• Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P and block
the rear wheels so the car cannot
roll. Then release the parking
brake.
• Do not hold the vehicle on the
upgrade with the accelerator
pedal. This can cause the trans-
mission to overheat. Always use
the brake pedal or parking brake.

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
inadvertently 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 sys-
tem.
(Continued)
(Continued)
• Be careful when driving
downhill using the cruise con-
trol system, which may
increase the vehicle speed.
