Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off while 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 dis-
tance, however, will be longer than
with power brakes.
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.
BRAKING SYSTEM
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 while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

Driving your vehicle
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.
Rear drum brakes
(if equipped)
Your rear drum brakes do not have
wear indicators. Therefore, have the
rear brake linings inspected if you
hear a rear brake rubbing noise. Also
have your rear brakes inspected
each time you change or rotate your
tires and when you have the front
brakes replaced.
Parking brake
Applying the parking brake
Always set the parking brake before
leaving the vehicle, to apply:
Firmly depress the brake pedal.
Pull up the parking brake lever as far
as possible.

Driving your vehicle
• Do not apply the accelerator
pedal while the parking brake is
engaged. If you depress the
accelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
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 (do not start the
engine).
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 while engine is running,
there may be a malfunction in the
brake system. Immediate attention is
necessary.

vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.
NOTICE

5-46
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
Engine Start/Stop button is in the ON
position. During that time, the ABS
will go through self-diagnosis and the
light will go off if everything is nor-
mal. If the light stays on, you may
have a problem with your ABS. We
recommend that you contact an
authorized HYUNDAI dealer as soon
as possible.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 engine off.
Restart the engine. 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 an
authorized HYUNDAI dealer 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
dealer as soon as possible.

Electronic Stability Control
(ESC) (if equipped)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.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.

■Left-hand drive
■Right-hand drive
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
maneuvers, and hydroplaning
on wet surfaces can result in
severe accidents.
WARNING

5-48
Driving your vehicle
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
• 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 ESC is
active.
• When the ESC activates, the
engine may not respond to the
accelerator as it does under routine
conditions.
• If the Cruise Control was in use
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)
• When moving out of the mud or
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 :
• State 1
Press the ESC OFF button briefly.
The ESC OFF indicator light and
message (vehicles equipped with a
supervision cluster) will illuminate. In
this state, the traction control func-
tion of ESC (engine management) is
disabled, but the brake control func-
tion of ESC (braking management)
still operates.• State 2
Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message (vehicles equipped
with a supervision cluster) illumi-
nates and a warning chime sounds.
In this state, both the traction control
function of ESC (engine manage-
ment) and the brake control function
of ESC (braking management) are
disabled.
If the ignition switch is placed to the
LOCK/OFF position when ESC is off,
ESC remains off. Upon restarting the
engine, the ESC will automatically
turn on again.

the ESC system. When this warning
light illuminates we recommend that
the vehicle be checked by an author-
ized HYUNDAI dealer as soon as
possible.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button.Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if

ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM) (if equipped)
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
tires 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 15 km/h (9 mph) on curve
roads.
• Vehicle speed is approximately
above 20 km/h (12 mph) 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 sub-
stitute for safe driving prac-
tices.
•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.
