Information
• Replace the filter according to theMaintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
• When the air flow rate suddenly decreases, we recommend that the
system be checked by a HYUNDAI
authorised repairer.
Checking the amount of air con-ditioner refrigerant and com-pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of on the
air conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by a HYUNDAI
authorised repairer.
i
Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.
WARNING
Vehicles equipped with
R-1234yf
Because the refriger-
ant is mildly inflam-
mable at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the
correct type and amount of oil
and refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend a HYUNDAI
authorised repairer replace any dam-
aged or leaking parts immediately.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by a HYUNDAI
authorised repairer.
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 a new vapour
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.

Maintenance
Checking the parking brake
Foot type (if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by a
HYUNDAI authorised repairer.
Stroke : 4~5 notch
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.OAE056014R

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
screen and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.
