Electronic Stability Control
(ESC)
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.

■Type A
■Type B
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

5-36
Driving your vehicle
To prevent damage to the trans-
mission:
• 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 opera-
tion.
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 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 substi-
tute for safe driving practices.
•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.

• NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
• NEVER locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the system.
• Pay extreme caution to keep the
camera out of water.
• NEVER arbitrarily disassemble
the camera assembly, nor apply
any impact on the camera
assembly.
• Playing the vehicle audio sys-
tem at high volume may offset
the system warning sounds.
Information
We recommend you have the system
checked by an authorized HYUNDAI
dealer when:
• The windshield glass is replaced.
• The front bumper is replaced.
• The radar sensor or cover gets dam-
aged or replaced.
Warning message and warning
light
Auto Emergency Braking disabled.
Radar blocked
When the sensor cover is blocked
with dirt, snow, or debris, the AEB
system operation may stop tem-
porarily. If this occurs, a warning
message will appear on the LCD dis-
play.
Remove any dirt, snow, or debris and
clean the radar sensor cover before
operating the AEB system.
The AEB may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.

• If you believe your brakes may be
wet, apply them lightly while driv-
ing 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 increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
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 sev-
eral 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
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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:
Information
Information for Snow Tires and Tire
Chains in the national language
(Bulgarian, Hungarian, Icelandic,
Polish) is provided in the Appendix.
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
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
If you mount snow tires on your vehi-
cle, 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 and municipal regula-
tions for possible restrictions against
their use.
i
i
WINTER DRIVING
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 affect-
ed.

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. When
there is the risk that your parking
brake may freeze, temporarily apply
it with the shift lever in P (Park). Also,
block the rear wheels in advance, so
the vehicle may not roll. Then,
release the parking brake.Do not let ice and snow accumu-
late underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in such conditions during the
severe winter, you should check
underneath the vehicle on a regular
basis, to ensure that the front wheels
and the steering components is
unblocked.
Carry emergency equipment
In accordance with weather condi-
tions, you should carry appropriate
emergency equipment, while driving.
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.Do not place objects or materials
in the engine compartment
Putting objects or materials in the
engine compartment may cause an
engine failure or combustion,
because they may block the engine
cooling. Such damage will not be
covered by the manufacturer's war-
ranty.

Driving your vehicle
Backing up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, move your hand
to the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and, if possi-
ble, have someone guide you.
Making turns
When you’re turning with a trailer,
make wider turns than normal. Do this
so your trailer won’t strike soft shoul-
ders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn signals
When you tow a trailer, your vehicle
has to have a different turn signal
flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever you signal a turn or
lane change. Properly connected,
the trailer lights will also flash to alert
other drivers you’re about to turn,
change lanes, or stop.When towing a trailer, the green
arrows on your instrument panel will
flash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers behind you are
seeing your signals when, in fact,
they are not. It’s important to check
occasionally to be sure the trailer
bulbs are still working. You must also
check the lights every time you dis-
connect and then reconnect the
wires.
Driving on hills
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
overheated and may not operate effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h (45 mph) to reduce the possi-
bility of engine and transmission
overheating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transmission/dual clutch transmis-
sion, you should drive in D (Drive)
when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build-up and extend the life of
your transmission.
5
Do not connect a trailer lighting
system directly to your vehi-
cle’s lighting system. Use an
approved trailer wiring harness.
Failure to do so could result in
damage to the vehicle electrical
system and/or personal injury.
Consult an authorized HYUNDAI
dealer for assistance.
