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, 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 bonnet, stop the
engine. Do not open the bonnet
until the coolant has stopped run-
ning 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 a HYUNDAI
authorised repairer for assistance.

Whilst 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.
WARNING
NEVER remove the
radiator cap or the
drain plug whilst 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 remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back whilst the
pressure is released from the
cooling system. When you are
sure 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 been
lost, 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 a
HYUNDAI authorised repairer for
assistance. (1) Low tyre pressure telltale /
TPMS malfunction indicator
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tyre inflation pressure label. (If
your vehicle has tyres of a different
size than the size indicated on the
vehicle placard or tyre inflation pres-
sure label, you should determine the
proper tyre inflation pressure for
those tyres.) As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is significantly under-
inflated. Accordingly, when the low
tyre pressure telltale illuminates, you
should stop and check your tyres as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure. Under-inflation also
reduces fuel efficiency and tyre tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tyre mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tyre pressure
telltale.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by a
HYUNDAI authorised repairer.
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 in
small quantities.

Maintenance
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by a HYUNDAI
authorised repairer.
Spark plugs
(for Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for Petrol Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by a HYUNDAI authorised
repairer.
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.
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

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 travelling
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 without 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 is
cool.
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, we
recommend that the system be
inspected by a HYUNDAI authorised
repairer.

MaintenanceThe 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.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Never remove the
coolant cap/radiator
cap or the drain plug
whilst 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 remov-
ing the coolant cap/radiator
cap. Wrap a thick towel around
it, and turn it counterclockwise
slowly to the first stop. Step
back whilst the pressure is
released from the cooling sys-
tem. When you are sure all the
pressure has been released,
press down on the cap, using a
thick towel, and continue turn-
ing counterclockwise to remove
it.
