System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dustor other pollutants that come into the
vehicle from the outside through theheating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.Information
 Replace the filter according to the Maintenance 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 an authorized
HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling alsohas a bad influence on the air condi-tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.

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 thatthe correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

Maintenance
Normal maintenance schedule
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both kilometrage and time are shown, the
frequency of service is determined by whichever occurs first.
R : Replace I : Inspect and, after Inspection, clean, adjust, repair or replace if necessary.
* 1
: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are available from your authorized HYUNDAI
dealer along with information on how to use them. Do not mix other additives.
* 2
: Inspect HSG belt for evidence of cuts, crocks, excessive wear or oil saturation and replace if necessary. If drive belt noise occurred, readjust
drive belt tension before replace.
* 3
: Fuel filter & Fuel tank air filter are considered to be maintenance free but periodic inspection is recommended for this maintenance schedule
depends on fuel quality. If there are some important safety matters like fuel flow restriction, surging, loss of power, hard starting problem etc,
replace the fuel filter immediately regardless of maintenance schedule and consult an authorized HYUNDAI dealer for details.

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 changesare required.
HSG (Hybrid starter & genera- tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
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 an authorized
HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vaporhose or fuel filler cap is correctlyreplaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
