Driving your vehicle
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 modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, 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 situa-
tion allow the ABS to control the force
being delivered to the brakes.
WARNING
ABS (or ESP) will not prevent acci-
dents due to improper or danger-
ous 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
during extreme road conditions.
The braking distance for vehicle
equipped with an anti-lock braking
system (or Electronic Stability
Program system) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
• Rough, gravel or snow-covered
roads.
• With tire chains installed.
• On roads where the road surface
is pitted or has different surface
height.
The safety features of an ABS (or
ESP) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.
CAUTION
If there is a malfunction with the dri-
ver’s door, hood or trunk open
detection system, the AUTO HOLD
may not work properly.
Take your vehicle to an authorized
HYUNDAI dealer and have the sys-
tem checked.
WARNING
• Press the accelerator pedal slow-
ly when you start the vehicle.
• For your safety, cancel the AUTO
HOLD when you drive downhill or
back up the vehicle or park the
vehicle.

✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
• Even with the anti-lock brake system,
your vehicle still requires sufficient
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 pre-
vent accidents resulting from exces-
sive speeds.
• On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
✽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 bat-
tery voltage. It does not mean your ABS
has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
W-78
CAUTION
• If the ABS warning light is on and
stays on, you may have a problem
with the ABS. In this case, howev-
er, your regular brakes will work
normally.
• 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.
CAUTION
• When you drive on a road having
poor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be
active continuously and the ABS
warning light may illuminate. Pull
your vehicle 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 prob-
lem with the ABS. Contact an
authorized HYUNDAI dealer as
soon as possible.

Electronic stability program (ESP)
The Electronic Stability Program (ESP)
system is designed to stabilize the
vehicle during cornering maneuvers.
ESP checks where you are steering and
where the vehicle is actually going. ESP
applies the brakes at individual wheels
and intervenes in the engine
management system to stabilize the
vehicle.The Electronic Stability Program (ESP)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESP will be effective in
preventing 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 con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESP is active.
✽NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Program System is functioning proper-
ly.
WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
program (ESP) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-
ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESP installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.

Good braking practices• Check to be sure the parking brake is
not engaged and that the parking
brake indicator light is out before driv-
ing 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.
WARNING
Never press the ESP OFF button
while ESP is operating.
If the ESP is turned off while ESP is
operating, the vehicle may go out of
control.
To turn ESP off while driving, press
the ESP OFF button while driving
on a flat road surface.WARNING
• Whenever leaving vehicle or
parking, always set the parking
brake and fully engage the vehi-
cle'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 your-
self or others.
• All vehicles should always have
the parking brake fully engaged
when parking to avoid inadver-
tent 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 extremely haz-
ardous. 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 driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
• If a tire goes flat while you are driving,
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 parking
brake can freeze in the engaged posi-
tion. This is most likely 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 park-
ing brake.
• Do not hold the vehicle on the upgrade
with the accelerator pedal. This can
cause the transmission to overheat.
Always use the brake pedal or parking
brake.

The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without pressing the acceler-
ator 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 activated
or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• To activate cruise control, depress the
brake pedal at least once after turning
the ignition switch to the ON position
or starting the engine. This is to check
if the brake switch which is important
part to cancel cruise control is in nor-
mal condition.

(CRUISE indicator light OFF)
when the cruise control is not in
use, to avoid inadvertently set-
ting 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 control system,
which may increase the vehicle
speed.

Limitations of the system
The smart cruise control system may
have limits to its ability to detect distance
to the vehicle ahead due to road and traf-
fic conditions.
On curves
• On curves, the smart cruise control
system may not detect a moving vehi-
cle in your lane, and then your vehicle
could accelerate to the set speed. Also,
the vehicle speed will slow down when
the vehicle ahead is recognized sud-
denly.
• Select the appropriate set speed on
curves and apply the brakes or accel-
erator pedal if necessary.• Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate set speed. Check to be
sure that the road conditions permit
safe operation of the smart cruise con-
trol.

CAUTION
• Do not install accessories around
the sensor and do not replace the
bumper by yourself. It may inter-
fere with the sensor performance.
• Always keep the sensor and
bumper clean.
• To prevent sensor cover damage
from occurring, wash the car with
a soft cloth.
• Do not damage the sensor or sen-
sor area by a strong impact. If the
sensor moves slightly off posi-
tion, the smart cruise control sys-
tem will not operate correctly.
If this occurs, have your vehicle
checked by an authorized
HYUNDAI dealer as soon as pos-
sible.
• Use only a genuine HYUNDAI
sensor cover for your vehicle.

On inclines
• During uphill or downhill driving, the
smart cruise control system may not
detect a moving vehicle in your lane,
and cause your vehicle to accelerate to
the set speed. Also, the vehicle speed
will slow down when the vehicle ahead
is recognized suddenly.
• Select the appropriate set speed on
inclines and apply the brakes or accel-
erator pedal if necessary.
Lane changing
• A vehicle which moves into your lane
from an adjacent lane cannot be rec-
ognized by the sensor until it is in the
sensor's detection range.
• The sensor may not detect immediate-
ly when a vehicle cuts in suddenly.
Always pay attention to the traffic, road
and driving conditions.
• If a vehicle which moves into your lane
is slower than your vehicle, your speed
may decrease to maintain the distance
to the vehicle ahead.
• If a vehicle which moves into your lane
is faster than your vehicle, your vehicle
will accelerate to the selected speed.
Vehicle recognition
Some vehicles ahead in your lane cannot
be recognized by the sensor as follows:
- Narrow vehicles such as motorcycles or
bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-decel-
erating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as
trailers with no loads

Driving your vehicle
A vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs:
- When the vehicle is pointing upwards
due to overloading in the trunk
- While the steering wheel is operating
- When driving to one side of the lane
- When driving on narrow lanes or on
curves
Apply the brakes or accelerator pedal if
necessary.(Continued)
• The smart cruise control system
is not a substitute for safe driving
practices but a convenience
function only. It is the responsi-
bility of the driver to always
check the speed and the distance
to the vehicle ahead.
• Always be aware of the selected
speed and vehicle to vehicle dis-
tance.
• Always maintain sufficient brak-
ing distance and decelerate your
vehicle by applying the brakes if
necessary.
• As the smart cruise control sys-
tem may not recognize complex
driving situations, always pay
attention to driving conditions
and control your vehicle speed.
• For safe operation, carefully read
and follow the instructions in this
manual before use.WARNING
• The vehicle cannot be stopped by
using the smart cruise control
system.
If an emergency stop is neces-
sary, you must apply the brakes.
• Keep a safe distance according
to road conditions and vehicle
speed. If the vehicle to vehicle
distance is too close during a
high-speed driving, it may cause
a serious collision.
• The smart cruise control system
can not recognize a stopped
vehicle, pedestrians or an
oncoming vehicle. Always look
ahead cautiously to prevent
unexpected and sudden situa-
tions from occurring.
• In front of you, vehicles moving
with a frequent lane change may
cause a delay in the system's
reaction or may cause the system
to react to a vehicle actually in an
adjacent lane. Always look ahead
cautiously to prevent unexpected
and sudden situations from
occurring.

CAUTION
The smart cruise control system
may not operate temporarily due to
electrical interference.
