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.

light illuminates we recommend that
the vehicle be checked by an authorized
HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
when the ESC is turned off with the
button.
WARNING
When the ESC is blinking, this indicates
the ESC is active:
Drive slowly and NEVER attempt to
accelerate. NEVER turn the ESC off
while the ESC indicator light is blinking
or you may lose control of the vehicle
resulting in an accident.
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
wheels and tires installed.

Driving your vehicle
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 while driving, press the
ESC OFF button while driving on a flat
road surface.
NOTICE
To prevent damage to the transmission:
• Do not allow wheel(s) of one axle to
spin excessively while 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 while these
lights are displayed.
• When operating the vehicle on
a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
i Information
Turning the ESC off does not affect ABS
or standard brake system operation.
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 suddenly on wet, slippery and
rough roads where traction over the four
tires can suddenly become uneven.
WARNING
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 substitute for safe
driving practices.
• Never drive too fast for the road
conditions. The VSM system will not
prevent accidents. Excessive speed
in bad weather, slippery and uneven
roads can result in severe accidents.

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.

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.

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.

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.
