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 nor-
mally would. The stopping distance, how-
ever, 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 neces-
sary to maintain steering control on slip-
pery surfaces.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 distance, however, will be
much greater than normal.
BRAKE SYSTEM WARNING
- Brakes
Do not drive with your foot rest- ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to oneside 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 fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performancereturns to normal.
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 mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

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 con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and
does not indicate a problem with your
brakes.Electronic parking brake (EPB)
Applying the parking brake
To engage the parking brake, first apply
the brake pedal and then press the EPB
switch. Make sure that the brake warninglight comes on.
Releasing the parking brake
To release the parking brake manually
with the engine start/stop button in the
ON position, pull the EPB switch while
depressing the brake pedal. Make sure
that the brake warning light goes off.
The parking brake will be released auto-
matically when you shift the shift lever
from P (Park) to R (Reverse), N (Neutral)
or D (Drive) while depressing the brakepedal.
Make sure that the brake warning light goes out.
If the parking brake does not release,
have the system checked by an author-
ized HYUNDAI dealer.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to aserious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace brake pads as complete front or rear axle sets.

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 reducedspeeds:
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 HOLDmay not work properly.
Take your vehicle to an authorizedHYUNDAI dealer and have the sys-
tem checked.

✽✽
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 problemwith the ABS. In this case, howev-er, your regular brakes will work normally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will go off if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorized HYUNDAI dealer assoon 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 beactive continuously and the ABSwarning light may illuminate. Pull
your vehicle over to a safe placeand 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 orpedestrians.

527
Driving your vehicle
Don't coast down hills with the vehicleout 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 y ou 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.

➀ CRUISE indicator
➁ SET indicator
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 (113mph).
✽✽ NOTICE
During normal cruise control operation,
when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.

instrument cluster illuminated)
the cruise control can be activat-
ed unintentionally. Keep the
cruise control system off
(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 vehiclespeed.

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 controlsystem 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 witha soft cloth.
Do not damage the sensor or sen- sor area by a strong impact. If thesensor moves slightly off posi-
tion, the smart cruise control sys-tem will not operate correctly.
If this occurs, have your vehiclechecked by an authorizedHYUNDAI dealer as soon as pos-
sible.
Use only a genuine HYUNDAI sensor cover for your vehicle.
