Maintenance
The following lists are vehicle checks
and inspections that should be
performed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer
as soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while 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 pacemaker, should
remain away from the ECU or the
wiring harness by at least 30 cm,
while running the diesel engine. The
high currents of the electronic engine
control system produce a considerable
amount of magnetic fields.
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
• Check the radiator and condenser.
Check if the front of the radiator and
condenser are clean and not blocked
with leaves, dirt or insects etc.
If any of the above parts are extremely
dirty or you are not sure of their
condition, we recommend that you
contact an authorized HYUNDAI
dealer.
WARNING
Be careful when checking your engine
coolant level when the engine is hot.
Scalding hot coolant and steam may
blow out under pressure. This could
cause burns or other serious injury.

Maintenance
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 level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
NOTICE
• Do not drive with no engine coolant.
It may cause water pump failure and
engine seizure, etc.
• 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.
Checking the coolant level
OBI3090008OBI3090008
„„Petrol Engine (1.0 T-GDi)Petrol Engine (1.0 T-GDi)
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 F (Full) and L (Low) marked 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 F (Full), but do
not overfill. If frequent additions are
required, we recommend that the
system be inspected by an authorized
HYUNDAI dealer.

Maintenance
Checking the washer fluid level
OBI3090038OBI3090038
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available.
However, use washer solvent with
antifreeze characteristics in cold
climates to prevent freezing.
WARNING
Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control or damage to the
paint and body trim.
• Windshield washer fluid agents
contain some amounts of alcohol
and can be flammable under certain
circumstances. Do not allow sparks
or flame come in contact with the
washer fluid or the washer fluid
reservoir. Damage to the vehicle or
occupants could occur.
• Windshield washer fluid is poisonous
to humans and animals. Do not drink
and avoid coming in contact with
the windshield washer fluid. Serious
injury or death could occur.
