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.

Indicator lights
When the ignition switch is pressed
to the ON position, the ESC indicator
light illuminates, then goes off if the
ESC system is operating normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If the ESC indicator light stays on,
your vehicle may have a malfunction
with the ESC system. When this
warning light illuminates we recom-
mend 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.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 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
■ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)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.
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.
WARNING

Driving your vehicle
Hill-Start Assist Control (HAC)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systems
are automatically released, when the
accelerator pedal is depressed.
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 nor-
mally.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while sharply and
severely braking.
The system is activated when:
• The vehicle suddenly stops. (The
deceleration power exceeds 7 m/s
2,
and the driving speed exceeds 55
km/h (34 mph).)
• The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights:
• When the driving speed is under
40 km/h (25 mph),
• When the ABS is deactivated, and
• When the sudden braking situation
is over.The hazard warning flasher turns
OFF:
• When the vehicle drives at a low
speed for a certain period of time.
The driver can manually turn OFF
the hazard warning flasher by
pressing the button.Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flashers are already on.
i
i
The HAC is activated only for
about 2 seconds, so always
depress the accelerator pedal
to begin driving upwards after a
stop.
WARNING

Trailer brakes
If your trailer is equipped with a brak-
ing system, make sure it conforms to
your country’s regulations and that it
is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes loaded, then it needs its
own brakes and they must be ade-
quate. Be sure to read and follow the
instructions for the trailer brakes so
you’ll be able to install, adjust and
maintain them properly. Be sure not
to modify your vehicle's brake sys-
tem.
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get
to know your trailer. Acquaint your-
self with the feel of handling and
braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now
longer and not nearly as responsive
as your vehicle is by itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and brakes.
During your trip, occasionally check
to be sure that the load is secure,
and that the lights and trailer brakes
are still working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and sud-
den turns.
Passing
You will need more passing distance
up ahead when you’re towing a trail-
er. And, because of the increased
vehicle length, you’ll need to go
much farther beyond the passed
vehicle before you can return to your
lane.
Driving your vehicle
Do not use a trailer with its own
brakes unless you are absolute-
ly certain that you have proper-
ly set up the brake system. This
is not a task for amateurs. Use
an experienced, competent trail-
er shop for this work.
WARNING

5-109
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.
WARNING

6-2
The hazard warning flasher serves as
a warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle.
It should be used whenever emer-
gency repairs are being made or
when the vehicle is stopped near the
edge of a roadway.To turn the hazard warning flasher
on or off, press the hazard warning
flasher button with the ignition switch
in any position. The button is located
in the center fascia panel. All turn
signal lights will flash simultaneously.
• The hazard warning flasher oper-
ates whether your vehicle is run-
ning or not.
• The turn signals do not work when
the hazard flasher is on.
If the engine stalls while driving
• Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place.
• Turn on your hazard warning flasher.
• Try to start the engine again. If your
vehicle will not start, we recom-
mend that you contact an author-
ized HYUNDAI dealer.
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroads or
crossing, if safe to do so, move the
shift lever to the N (Neutral) position
and then push the vehicle to a safe
location.

What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Place the shift lever in P (Park)
and set the parking brake3. Make sure that there is no hot
steam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pump
connector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air
flow to the maximum, and turn ON
the air conditioner.5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hot
steams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature
gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.
IF THE ENGINE OVERHEATS
While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
