Maintenance
NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE (2.0L) - MPI
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 mileage and time are shown, the frequency of service is deter-
mined by whichever occurs first.
*
1: Inspect drive belt tensioner, idler and alternator pulley andif necessary correct or replace.
*
2: Check the engine oil level and leak every 500 km (350 miles) or before starting a long trip.
*
3: Driving in outer temperature over 40 °C (104 °F) or driving over 170 km/h (106 mile/h) must conform the severe driving
condition.
*
4: If good quality gasolines that meet Europe Fuel standards (EN228) or equivalents including fuel additives is not avail-
able, 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
*
5: For your convenience, it can be replaced prior to it's interval when you do maintenance of other items.
*
6: The engine oil level should be checked regularly and main- tained properly. Operating with an insufficient amount of oil
can damage the engine, and such damage is not covered
by warranty. *
7: If the recommended oil and oil filter are not available, replace
engine oil and engine oil filter every 7,500 km or 6 months.
*
8: The fuel filter is considered to be maintenance free but peri- odic inspection is recommended for this maintenance
schedule depends on fuel quality. If there are some impor-
tant matters like fuel flow restriction, surging, loss of power,
hard starting problem etc, replace the fuel filter immediate-
ly regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details.
*
9: When adding coolant, use only deionized 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.
*
10: Manual transaxle fluid should be changed anytime they have been submerged in water.

NORMAL MAINTENANCE SCHEDULE - FOR DIESEL ENGINE (EXCEPT EUROPE)
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 mileage and time are shown, the frequency of service is deter-
mined by whichever occurs first.
*
1: Check the engine oil level and leak every 500 km (350
miles) or before starting a long trip.
*
2: Driving in summer season temperature over 40 °C (104 °F - SAUDI, UAE, OMAN, KUWAIT, BAHRAIN, QATAR, IRAN,
YEMEN ETC) or driving over 170 km/h (106 mile/h) must
conform the severe driving condition.
*
3: This maintenance schedule depends on fuel quality. It is applicable only when using a qualified fuel <"EN590 or
equivalent">. If the diesel fuel specifications don't meet the
EN590, it must be replaced according to the severe mainte-
nance schedule.
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 main-
tenance schedule and consult an authorized HYUNDAI
dealer for details
*
4: The engine oil level should be checked regularly and main- tained properly. Operating with an insufficient amount of oil
can damage the engine, and such damage is not covered
by warranty.
*
5: Inspect for excessive valve noise and/or engine vibration
and adjust if necessary. An authorized HYUNDAI dealer
should perform the operation. *
6: Manual transaxle should be changed anytime they have
been submerged in water.
*
7: The fuel filter is considered to be maintenance free but peri- odic inspection is recommended for this maintenance

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully. 5. Pull the dipstick out again and check
the level. The level should be between
F and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use a funnel to help prevent oil from
being spilled on engine components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci-ties” in section 8.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.
OVF071004OVF071005
CAUTION - Diesel engine
Overfilling the engine oil may cause severe dieseling due to churningeffect. It may lead to engine damageaccompanied with abrupt enginespeed increment, combustion noise and white smoke emission.
CAUTION
Do not overfill the engine oil. It may damage the engine.
Do not spill engine oil, when adding or changing engine oil. Ifyou drop the engine oil on theengine room, wipe it off immedi- ately.

Maintenance
ENGINE COOLANT
Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule at the begin-
ning of this section.The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter sea-
son, and before traveling to a colder cli-
mate.
Checking the coolant level
WARNING
Removing radiator
cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
Turn the engine off and wait until it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.

WARNING
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

BRAKE/CLUTCH FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir. Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants and capac-ities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
CAUTION
Do not allow brake fluid to contactthe vehicle's body paint, as paint damage will result. Brake fluid,which has been exposed to open air for an extended time should neverbe used as its quality cannot beguaranteed. It should be disposed of properly. Don't put in the wrongkind of fluid. A few drops of miner-al-based oil, such as engine oil, in your brake system can damagebrake system parts.
