Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the diesel engine for several min-
utes, and check the connections for
any leakages. We recommend you to
have the fuel filter replaced by a
HYUNDAI authorised repairer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by a HYUNDAI authorised
repairer.
When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
CAUTION
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine. When
the fuel leakage vents out, it may
cause serious body injury. Any
people, who are implemented
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm whilst running the
diesel engine. The high currents
of the common rail system pro-
duce a considerable amount of
magnetic fields.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
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 assure
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 dam-
age. Replace any damaged parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions. We recommend that the
automatic transaxle fluid changed by
a HYUNDAI authorised repairer
according to the maintenance sched-
ule.
Information
Automatic transaxle fluid colour is
basically red. As the vehicle is driven,
the automatic transaxle fluid will begin
to look darker. It is normal condition
and you should not judge the need to
replace the fluid based upon the
changed colour.
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
The use of a non-specified fluid
could result in transaxle malfunc-
tion and failure.
Use only specified automatic
transaxle fluid.
(Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance sched-
ule.
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 brake 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 conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.
Brake pads, calipers and
rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the HYUNDAI web site.

Maintenance
ENGINE COOLANT
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 fromlow 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 marks on the
side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionised) or soft water.
Bring the level to MAX, but do not
overfill.
If frequent additions are required, we
recommend that the system be inspect-
ed by a HYUNDAI authorised repairer.

Maintenance
Removing radiatorcap
• Never attempt to remove the
radiator cap whilst the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
(Continued)
WARNING (Continued)
•Turn the engine off and wait
until it cools down. Use
extreme care when removing
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 counterclockwise to
remove it.
• Even if the engine is not oper-
ating, do not remove the radi-
ator cap or the drain plug
whilst the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
