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 soonas it is safe to do so.
2. Place the shift lever in P (Park, for dual clutch transmission vehicle)
or neutral (for manual transmis-
sion/dual clutch transmission vehi-
cle) and set the parking brake. If
the air conditioning is ON, turn it
OFF.
3. If engine coolant is running out under the vehicle or steam is com-ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off. 4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had been
in use, it is normal for cold water to
be draining from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and we rec-
ommend that you call an authorized
HYUNDAI dealer for assistance.

While the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as thecooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the radiator cap or thedrain plug while theengine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

6. If you cannot find the cause of theoverheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has beenlost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorized HYUNDAI dealer for
assistance. (1) Low tire pressure telltale /
TPMS malfunction indicator
Each tire, including the spare (if pro-
vided), should be checked monthlywhen cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of yourtires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Serious loss of coolant indi- cates a leak in the coolingsystem and we recommend
the system be checked by an
authorized HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly insmall quantities.

Maintenance
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.
Spark plugs
(for Gasoline Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for Gasoline Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorized HYUNDAI
dealer.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual transmission fluid (if equipped)
Inspect the manual transmission fluid according to the maintenance
schedule.
Dual clutch transmission fluid (if equipped)
Inspect the dual clutch transmission fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch fluid (if equipped)
Check the brake/clutch fluid level in
the brake fluid reservoir. The level
should be between “MIN” and “MAX”
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-cation.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.
Do not disconnect and inspectspark plugs when the engine is
hot. You may burn yourself.

Maintenance
Checking the engine oil and filter
We recommend that the engine oil
and filter be replaced by an author-
ized HYUNDAI dealer.The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before traveling
to a colder climate.
When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
Do not drive with no engine coolant. It may cause water pump
failure and engine seizure, etc.
Checking the engine coolant
level
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between MAX and MIN (or F (Full)
and L (Low)) marks on the side of the
coolant reservoir when the engine iscool.
NOTICE
Used engine oil may cause irri- tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soapand warm water as soon as pos-
sible after handling used oil.

Maintenance
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to MAX, (or F (Full)) but do not
overfill.
If frequent additions are required, werecommend that the system be
inspected by an authorized HYUNDAI
dealer.
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with T-GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.
OOS077009
■Gasoline engine The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan bladesof the cooling fan.
WARNING
Never remove the
coolant cap/radiator cap or the drain plugwhile the engine and
radiator are hot. Hot
coolant and steam may blow out
under pressure, causing serious
injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
coolant cap/radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
