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.

telltale
Low tire pressure position and
tire pressure telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and a warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-
cate which tire is significantly under-
inflated by illuminating the corre-
sponding position light.If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel.
If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
10 minutes at speed above 25 km/h
(15.5 mph)) until you have the low
pressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.

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 windshield washer fluid
level.
• Check for low or under-inflated
tires.
While 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 traveling 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
tires including the spare for tires
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 windshield 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.

Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on while the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electrical load
while the vehicle is being used,
recharge it at 20-30A for two hours.Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
•Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the Engine Start/
Stop button to the OFF posi-
tion.
•Keep all flames, sparks, or
smoking materials away from
the battery.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorized HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.

Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
CAUTION
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
•A higher capacity fuse could
cause damage and possibly
cause a fire.
•Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

LIGHT BULBS
Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
Information
After heavy driving rain or washing,
the lamps could appear frosty. This
condition is caused by the temperature
difference between the lamp inside and
the outside temperature. This is similar
to the condensation on your windows
inside your vehicle when raining and
doesn’t indicate a problem with your
vehicle. If the water leaks into the light
bulb circuitry, have your vehicle
checked by an authorized HYUNDAI
dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
• The position lamp may not turn on
when the position lamp switch is
turned on, but the position lamp and
headlamp switch may turn on when
the headlamp switch is turned on.
This may be caused by network fail-
ure or vehicle electrical control sys-
tem malfunction. If this occurs, we
recommend the system be checked
by an authorized HYUNDAI dealer.

and carefully dispose of it.
Information
Traffic Change (For Europe)
The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direc-
tion, this asymmetric part will dazzle
oncoming car driver. To prevent daz-
zle, ECE regulation demand several
technical solutions (ex. automatic
change system, adhesive sheet, down
aiming). This headlamps are designed
not to dazzle opposite drivers. So, you
need not change your headlamps in a
country with opposite traffic direc-
tion.

OAE076028
•Handle halogen bulbs with
care. Halogen bulbs contain
pressurized gas that will pro-
duce flying pieces of glass
that could cause injuries if
broken.
•Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.
