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 distance, 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 control
on slippery surfaces.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending a long or steep
hill, shift to a lower gear and avoid
continuous application of the brakes.
Applying the brakes continuously
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 fashion after driving
through deep water. To dry the
brakes, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
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.
Please remember 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.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
i Information
Always replace brake pads as complete
front or rear axle sets.

Driving your vehicle
Rear drum brakes
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
OAI3069006OAI3069006
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.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH, do not operate the parking
brake while the vehicle is moving
except in an emergency situation. It
could damage the brake system and
lead to an accident.
OAI3069007OAI3069007
To release:
Firmly depress the brake pedal.
Slightly pull up the parking brake lever.
While pressing the release button (1),
lower the parking brake (2).
If the parking brake does not release
or does not release all the way, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
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
the 1st gear (for manual transmission
vehicle) or N (Neutral) position (for
Automated Manual Transmission
vehicle), 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.

Driving your vehicle
Anti-lock Brake System (ABS)
WARNING
An Anti-Lock Braking System (ABS) or
an Electronic Stability Control (ESC)
system 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 of you. Vehicle speeds should
always be reduced during extreme
road conditions. The braking distance
for vehicles 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-covered
roads.
• On roads where the road surface is
pitted or has different surface height.
• Tire 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.
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
distance 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 conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering 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 system
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 ignition
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 recommend that you contact
an authorized HYUNDAI dealer as soon
as possible.

WARNING
If the ABS warning light () is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, we recommend that
you contact your HYUNDAI dealer as
soon as possible.
NOTICE
When you drive on a road having poor
traction, such as an icy road, and apply
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
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 problem
with your ABS system. We recommend
that you contact an authorized
HYUNDAI dealer as soon as possible.
i 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.
Electronic Stability Control
(ESC) (if equipped)
OBI3060006OBI3060006
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 management 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.
WARNING
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.

Driving your vehicle
ESC operation
ESC ON condition
When the ignition switch is in the
ON position, the ESC and the ESC
OFF indicator lights illuminate for
approximately three seconds and goes
off, then the ESC is turned on.
When operating
When the ESC is in
operation, 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 reengaged when the
road conditions allow. See “Cruise
Control System” later in this chapter
7 (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

Press the ESC OFF button briefly.
The ESC OFF indicator light and/or
message “Traction control disabled” will
illuminate and a warning chime sounds.
In this state, the traction control function
of ESC (engine management) is disabled,
but the brake control function of ESC
(braking management) still operates.

VSM operation
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 sensation in the
brake pedal. This is normal and it means
your VSM is active.
i Information
The VSM does not operate when:
• Driving on a banked road such as
gradient or incline
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric Power Steering)
warning light (
) is on or blinks.
WARNING
If the ESC indicator light () or
EPS warning light (
) stays on
or blinks, your vehicle may have a
malfunction with the VSM system.
When the warning light illuminates
we recommend that the vehicle be
checked by an authorized HYUNDAI
dealer as soon as possible.
NOTICE
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
tires and wheels installed.
Hill-Start Assist Control (HAC)
(if equipped)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle from
a stop on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off on
a incline. The HAC activates only for
approximately 2 seconds.
i Information
• The HAC does not operate when the
shift lever is in P (Park) or N (Neutral).
• The HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when the
ESC does not operate normally.

7-46
Driving your vehicle
Emergency Stop Signal (ESS)
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 (vehicle
speed is over 55 km/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 10 km/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
manually by pushing the hazard warning
flasher switch.
CAUTION
The Emergency Stop Signal (ESS)
system will not work if the hazard
warning flasher is already on.
Good braking practices
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 the 1st
gear (for manual transmission vehicle)
or N (Neutral) position (for Automated
Manual Transmission vehicle), 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.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it is
washed. Your vehicle 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 vehicle
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 we
recommend that you call an authorized
HYUNDAI dealer for assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.

7-47

If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle 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 location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

7-49

Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
• Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare
from other driver’s headlights.
• Keep your headlights clean and
properly aimed. Dirty or improperly
aimed headlights will make it much
more difficult to see at night.
• Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to
readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:
• Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.
• Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.
• Be sure your tires have enough tread.
If your tires do not have enough tread,
making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. See “Tire replacement” in
chapter 9.
• Turn on your headlights to make it
easier for others to see you.
• Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet. The risk of hydroplaning
increases as the depth of tire tread
decreases, refer to “Tire replacement” in
chapter 9.

7-50
Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
