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.

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.

7-45
07
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.

Driving your vehicle
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud or sand:
Drive cautiously and allow extra distance
for braking.
Avoid sudden movements in braking or
steering.
If stuck in snow, mud, or sand, use
second gear. Accelerate slowly to avoid
spinning the drive wheels.
WARNING
Downshifting with an Automated
manual transmission, while driving
on slippery surfaces can cause an
accident. The sudden change in tire
speed could cause the tires to skid. Be
careful when downshifting on slippery
surfaces.
Use sand, rock salt, or other non-slip
material under the drive wheels to
provide traction when stalled in ice,
snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first
turn the steering wheel right and left
to clear the area around your front
wheels. Then, shift back and forth
between 1st and R (Reverse, for manual
transmission vehicle) or R (Reverse) and
a forward gear (for Automated manual
transmission vehicle). Try to avoid
spinning the wheels, and do not race the
engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes
a rocking motion that may free the
vehicle.
NOTICE
If the tires spin at high speed the tires
can explode, and you or others may be
injured. Do not attempt this procedure
if people or objects are anywhere near
the vehicle.
The vehicle can overheat causing an
engine compartment fire or other
damage. Spin the wheels as little as
possible and avoid spinning the wheels
at speeds over 56 km/h (35 mph) as
indicated on the speedometer.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage
to the transmission, and tire damage.
See “Towing” in chapter 8.

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.

7-51

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 skids
to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, 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.
We recommend you use snow tires
when road temperature is below 45°F
(7°C).
i Information
Do not install studded tires without first
checking local and municipal regulations
for possible restrictions against their use.
Tire chains
OBI3060007LOBI3060007L
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them. Therefore,
the use of snow tires is recommended
instead of tire chains. Do not mount
tire chains on vehicles equipped with
aluminum wheels; if unavoidable use
a wire type chain. If tire chains must
be used, use genuine HYUNDAI parts
and install the tire chain after reviewing
the instructions provided with the tire
chains. Damage to your vehicle caused
by improper tire chain use is not covered
by your vehicle manufacturer’s warranty.
WINTER DRIVING

7-52
Driving your vehicle
WARNING
The use of tire chains may adversely
affect vehicle handling:
• Drive less than 30 km/h (20 mph)
or the chain manufacturer’s
recommended speed limit,
whichever is lower.
• Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the vehicle
to bounce.
• Avoid sharp turns or locked wheel
braking.
i Information
• Install tire chains on the front tires.
It should be noted that installing
tire chains on the tires will provide
a greater driving force, but will not
prevent side skids.
• Do not install tire chains without
first checking local and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 30 km/h (20 mph)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park
the vehicle on level ground away from
traffic. Turn on the vehicle Hazard
Warning Flasher and place a triangular
emergency warning device behind the
vehicle (if available). Always place the
vehicle in N (Neutral), apply the parking
brake and turn off the engine before
installing snow chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage, retighten
the chains after driving 0.5~1.0 km
(0.3~0.6 miles).
• Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 15 mm (0.59
in) wide to prevent damage to the
chain’s connection.

7-54
Driving your vehicle
Don’t 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
shift lever in N (for Automated Manual
Transmission) or in first or reverse gear
(for manual transmission) and block the
rear wheels so the vehicle cannot roll.
Then release the parking brake.
Don’t 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.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate
emergency equipment. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Don’t place foreign objects
or materials in the engine
compartment
Placement of foreign objects 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.
