Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle is turned
off whilst driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will
be longer than with power brakes.
When the vehicle is not in the ready
( ) mode, 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.

Take the following precautions:
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 down a
long or steep hill, move the
shift lever to Manual Shift
mode and manually downshift
to a lower gear in order to
control your speed without
using the brake pedal exces-
sively. Applying the brakes
continuously will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
(Continued)
(Continued)
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. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes whilst maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

5-28
Driving your vehicle
Do not continue depressing the brake pedal if the " "indica-
tor is OFF. The battery may be
discharged.
Noise and vibration generated during braking is normal.
Under normal operation, electric brake pump noise and motor
vibration may occur temporarily
in below cases.
- When the pedal is depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated whilst braking.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions 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.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Parking brake
Applying the parking brake
Always set the parking brake before
leaving the vehicle.
To apply the parking brake:
Firmly depress the brake pedal.
Depress the parking brake pedal
down as far as possible.

ly.
If the parking brake does not release
or does not release all the way, we
recommend that you have your vehi-
cle checked by a HYUNDAI autho-
rised repairer.
OAE056013R
To reduce the risk of SERIOUS
INJURY or DEATH, do not oper-
ate the parking brake whilst the
vehicle is moving except in an
emergency situation. It could
damage the brake system and
lead to an accident.
WARNING
Whenever leaving the vehicle
or parking, always come to a
complete stop and continue
to depress the brake pedal.
Move the shift lever into P
(Park) position, then apply the
parking brake, and place the
ignition switch in the LOCK/
OFF position.
Vehicles with the parking
brake not fully engaged are at
risk for moving inadvertently
and causing injury to yourself
or others.
When parking on an incline,
block the wheels to prevent the
vehicle from rolling down.
NEVER allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If the
parking brake is released
unintentionally, serious injury
may occur.
Only release the parking
brake when you are seated
inside the vehicle with your
foot firmly on the brake pedal.
WARNING

5-30
Driving your vehicle
Do not apply the accelerator pedal whilst the parking brake is
engaged. If you depress the
accelerator pedal with the park-
ing brake engaged, a warning
will sound. Damage to the park-
ing brake may occur.
Driving with the parking brake on can overheat the braking system
and cause premature wear or
damage to brake parts. Make sure
the parking brake is released and
the Brake Warning Light is off
before driving. Check the Parking
Brake Warning Light
by placing the ignition
switch to the ON posi-
tion vehicle not in the
ready ( ) mode.
This light will be illuminated when the
parking brake is applied with the igni-
tion switch in the START or ON posi-
tion.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF. If the Parking Brake Warning Light
remains on after the parking brake is
released whilst the vehicle is in the
ready ( ) mode, there may be a
malfunction in the brake system.
Immediate attention is necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution whilst
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.

Anti-lock Brake System (ABS)
ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.
(Continued)On roads where the road sur-
face is pitted or has different
surface height.
Tyre chains are installed on
your vehicle.
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.An Anti-Lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
manoeuvres. Even though vehi-
cle control is improved during
emergency braking, always
maintain a safe distance
between you and objects ahead
of you. Vehicle speeds should
always be reduced during
extreme road conditions. The
braking distance for cars
equipped with ABS or ESC may
be longer than for those without
these systems in the following
road conditions.
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads. (Continued)
WARNING

5-32
Driving your vehicle
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the igni-
tion switch is in the ON position.
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. We recom-
mend that you contact a HYUNDAI
authorised repairer as soon as pos-
sible. When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system. We
recommend that you contact a
HYUNDAI authorised repairer as
soon as possible.
Information
When you jump start your vehicle
because of a drained battery, the ABS
warning light ( ) may turn on at the
same time. This happens because of
the low battery voltage. It does not
mean your ABS is malfunctioning.
Have the battery recharged before
driving the vehicle.
i
NOTICE
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, we recommend
that you contact your HYUNDAI
authorised repairer as soon as
possible.

Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering manoeu-
vres.ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path. It is not a substitute
for safe driving practices. Always
adjust your speed and driving to the
road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds. After both
lights go off, the ESC is enabled.

OAE056016R
■
Type A
■Type B
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres, and hydroplaning
on wet surfaces can result in
severe accidents.
WARNING

5-34
Driving your vehicle
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ESC is
active.
cle may not respond to the acceler-
ator as it does under routine condi-
tions.
when the ESC activates, the Cruise
Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow. See "Cruise Control System"
later in this chapter. (if equipped)
driving on a slippery road, the
engine rpm (revolutions per minute)
may not increase even if you press
the accelerator pedal deeply. This is
to maintain the stability and traction
of the vehicle and does not indicate
a problem.
ESC OFF condition
To cancel ESC operation :

Press the ESC OFF button briefly.
The ESC OFF indicator light and
message "Traction Control disabled"
will illuminate. In this state, the trac-
tion control function of ESC (engine
management) is disabled, but the
brake control function of ESC (brak-
ing management) still operates.
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message "Traction & Stability
Control disabled" illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the ignition switch is placed in the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
vehicle, the ESC will automatically
turn on again.

Indicator lights
When the ignition switch is pressed
to the ON position, the ESC indicator
light illuminates, then goes off if the
ESC system is operating normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If the ESC indicator light stays on,
your vehicle may have a malfunction
with the ESC system. When this
warning light illuminates we recom-
mend that the vehicle be checked by
a HYUNDAI authorised repairer as
soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button.Driving with wheels and tyres with
different sizes may cause the ESC
system to malfunction. Before
replacing tyres, make sure all four
tyres and wheels are the same
size. Never drive the vehicle with
different sized wheels and tyres
installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud, by temporarily
stopping operation of the ESC, to
maintain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.
NOTICE
■
ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off whilst the ESC indicator
light is blinking or you may lose
control of the vehicle resulting in
an accident.
WARNING

5-36
Driving your vehicle
To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle to spin excessively whilst the
ESC, ABS, and parking brake
warning lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively whilst
these lights are displayed.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tyres can suddenly become uneven.
VSM operation
VSM ON condition
The VSM operates when:
The Electronic Stability Control(ESC) is on.
Vehicle speed is approximately above 9 mph (15 km/h) on curve
roads.
Vehicle speed is approximately above 12 mph (20 km/h) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a substi-
tute for safe driving practices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
