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.
