Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering manoeu-
vres.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 when cornering. The
ESC system will not prevent
accidents.
Excessive speed in turns, abrupt
manoeuvres, and hydroplaning
on wet surfaces can result in
severe accidents.

Indicator lights
When the ignition switch is set 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 authorised HYUNDAI dealer as
soon as possible.
The ESC OFF indicator light comes
on when ESC is turned off.Driving with wheels and tyres with
different sizes may cause the ESC
system to malfunction. Before
replacing tyres, make sure all four
tyres and wheels are the same
size. Never drive the vehicle with
different sized wheels and tyres
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 ESC, to main-
tain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.
NOTICE

To prevent damage to the trans-
mission:
Do not allow wheel(s) of one axle
to spin excessively whilst 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 whilst
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 the vehicle stay stable when
accelerating or braking suddenly on
wet, slippery and rough roads where
traction over the four tyres can sud-
denly 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 on curve roads.
Vehicle speed is approximately
above 20 km/h 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.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
rearwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
Information
• HAC does not operate when the shift
lever is in P (Park) or N (Neutral).
• HAC activates even when the ESC
(Electronic Stability Control) is off.
However, it does not activate, when
ESC does not operate normally.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, whilst 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.)
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,
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.

Always be ready to depress the
accelerator pedal when starting
off an incline. The HAC activates
only for approximately 2 sec-
onds.

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 centre 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 whilst driv-
ing
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 autho-
rised HYUNDAI dealer.

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 authorised
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, whilst 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 authorised
HYUNDAI dealer.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the dual clutch transmission
P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the engine
coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function. Be careful when checking your
engine coolant/inverter coolant
level when the engine is hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.
