Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the enginecoolant reservoir.
• Check the windscreen washer fluid level.
• Check for low or under-inflated tyres.
Whilst 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 position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
travelling 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 transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle/ 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).
Be careful when checking your
engine 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.
WARNING
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-pres-
sure 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 pacemaker, 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
electric engine control system
produce a considerable amount
of magnetic fields.

Maintenance
At least monthly:
• Check coolant level in the enginecoolant reservoir.
• Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tyres including the spare for tyres
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 Fall)
• Check radiator, heater and air condi-
tioning hoses for leaks or damage.
• Check windscreen washer spray and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and bonnethinges.
• Lubricate door and bonnet locks and latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate automatic transaxle linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

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
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.
