NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE (1.6L/2.0L) - GDI/DIESEL ENGINE (1.7L) (ONLY 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: 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.
*
3: If the recommended oil is not available, replace engine oil and engine oil filter every 20,000 km or 12 months.
*
4: If the recommended oil and oil filter are not available, replace engine oil and engine oil filter every 15,000 km or
12 months.
*
5: 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.
*
6: 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 more frequently. 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 sched-
ule and consult an authorized HYUNDAI dealer for details. *
7: 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 immediately
regardless of maintenance schedule and consult an author-
ized HYUNDAI dealer for details.
*
8: Manual transaxle fluid should be changed anytime they have been submerged in water.
*
9: Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or replace.
*
10: 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.
*
11: Inspect for excessive valve noise and/or engine vibration and adjust if necessary. An authorized HYUNDAI dealer
should perform the operation.
*
12: 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.
*
13: Driving in outer temperature over 40 °C (104 °F) or driving over 170 km/h (106 mile/h) must conform the severe driving
condition.

Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is replaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
(for gasoline engine 1.6L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.
✽ ✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

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.
(Continued)
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.
