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, contact your HYUNDAI dealer as soon as possible.
CAUTION
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 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 problem
with your ABS system. 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.
Electronic Stability Control (ESC) (if equipped)
OCN7060021
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.

Indicator lights
■ ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)
When the ignition switch is placed to
the ON position, the ESC indicator light
illuminates, then goes off if the ESC
system is operating normally.
The ESC indicator light blinks whenever
the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning light
illuminates have your vehicle checked by
an authorized HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on
when the ESC is turned off.
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.
ESC OFF usage
When Driving
The ESC OFF mode should only be used
briefly to help free the vehicle if stuck in
snow 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).
Information
Turning the ESC off does not affect ABS
or standard brake system operation.
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 suddenly on wet, slippery and
rough roads where traction over the four
tires can suddenly become uneven.

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.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead
to sudden tire failure that may cause
loss of vehicle control resulting in an
accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tow straps or chains, a flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
If you mount snow tires on your vehicle,
make sure to use radial tires of the same
size and load range as the original tires.
Mount snow tires on all four wheels
to balance your vehicle’s handling in
all weather conditions. The traction
provided by snow tires on dry roads
may not be as high as your vehicle's
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
Information
Do not install studded tires without first checking local, country and municipal
regulations for possible restrictions against
their use.

Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Change to "winter weight" oil if necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary. Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
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
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.

Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.
