Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in the
engine coolant 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 transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
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-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
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 electronic engine control
system produce a considerable
amount of magnetic fields.
WARNING

Maintenance
At least monthly:
Check coolant level in the engine
coolant 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 nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened 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 bonnet
hinges.
Lubricate door and bonnet locks
and latches.
Lubricate door rubber weather
strips.
Check the air conditioning system.
Inspect and lubricate automatic
transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

age the engine, and such damage is not covered by warranty.
*
4: If good quality petrols meet Europe Fuel standards (EN228) or equivalents including fuel additives is not available, one bottle

*6: The fuel filter is considered to be maintenance free but periodic inspection is recommended for this maintenance schedule
depending on fuel quality. If there are some important matters like fuel flow restriction, surging, loss of power, or hard starting
problems etc, we recommend replacing the fuel filter immediately regardless of maintenance schedule and consulting with an
authorised HYUNDAI dealer for details.
*
7: When adding coolant, use only deionised water or soft water for your vehicle and never mix hard water in the coolant filled at
the factory. An improper coolant mixture can result in serious malfunction or engine damage. For your convenience, it can be
replaced prior to it's interval when you do maintenance of other items.
