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 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 or before
starting a long trip.
* 2
: The engine oil level should be checked regularly and main-
tained properly. Operating with an insufficient amount oil
can damage the engine, and such damage is not covered
by warranty.
* 3
: Inspect and if necessary correct or replace. Inspect drive
belt tensioner, idler and alternator, pulley and if necessary
correct or replace.
* 4
: 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. We recommend that
you consult an authorised HYUNDAI dealer for details.
* 5
: 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. HYUNDAI rec-
ommends "every 7,500km inspection, every 15,000kmreplacement". If there are some important safety matters like fuel flow
restriction, surging, loss of power, hard starting problemetc., replace the fuel filter immediately regardless of main-
tenance schedule. We recommend that you consult an
authorised HYUNDAI dealer for details.
* 6
: Manual transaxle fluid, transfer case oil and rear differential
oil should be changed anytime they have been submerged
in water.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
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 fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically forproper tension and adjusted as neces-
sary. Fuel filter (cartridge) 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 exces-
sive amount of foreign matter accumu-
lates 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. We recommend that
the fuel filter be replaced by an autho-
rised HYUNDAI dealer.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connections be replaced by an
authorised HYUNDAI dealer.
WARNING -
Diesel only
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectorsand high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.

Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller 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 movingcomponent 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
We recommend that you use air cleaner
filter for replacement from an authorised
HYUNDAI dealer.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range. 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, we recommend
that the fluid be changed by an autho-
rised HYUNDAI dealer in accordance tothe scheduled maintenance at the begin-
ning of this chapter.
✽✽
NOTICE
Automatic transaxle fluid colour 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 colour.

Maintenance
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately. Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.Parking brake
Inspect the parking brake system includ-
ing the parking brake lever and cables.
Brake pads, calipers and rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
For more information on checking the
pads or lining wear limit, refer to the
Hyundai web site. (

ual.hmc.co.kr)
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque. Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints for
deterioration, cracks, or damage.
Replace any damaged parts. Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant/ compressor (if equipped)
Check the air conditioning lines and con-
nections for leakage and damage.
CAUTION

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 frombeing 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.
OLM073003OLM073004
CAUTION - Diesel engine
Overfilling the engine oil may cause
severe dieseling due to churning effect. It may lead to engine damageaccompanied with abrupt engine speed 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. If
you drop the engine oil on theengine room, wipe it off immedi- ately.

ENGINE COOLANT
Changing the engine oil and filter
We recommend that the engine oil and
filter be replaced by an authorised
HYUNDAI dealer. 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 travelling to a colder cli-
mate.
Checking the coolant level
WARNING
Removing radiatorcap
 Never attempt to remove the radi- ator cap whilst the engine is
operating or hot. Doing so mightlead to cooling system and
engine damage and could result
in serious personal injury fromescaping 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.
(Continued)
(Continued)Step back whilst the pressure is
released from the cooling sys-
tem. When you are sure all thepressure has been released,
press down on the cap, using a
thick towel, and continue turning
counterclockwise to remove it.
 Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
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 thoroughlywith soap and warm water as soon
as possible after handling used oil.

Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant refill is required, we rec-
ommend that the system be inspected by
an authorised HYUNDAI dealer.
Recommended engine coolant
 When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
 The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
 DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
 Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.

WARNING The electric motor (cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that
you are not injured by a rotating fan
blades. As the engine coolant tem-
perature decreases, the electric
motor will automatically shut off.This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the nagative battery cable.

BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch fluid
level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add fluid to the MAX
(Maximum) level. The level will fall with
accumulated mileage. This is a normal
condition associated with the wear of the
brake linings and/or clutch disc (ifequipped). If the fluid level is excessively low, we
recommend that the brake system be
checked by an authorised HYUNDAI
dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants or capacities” in section 8.)
Never mix different types of fluid.
OYF073224R
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,
we recommend that the vehicle be
inspected by an authorised
HYUNDAI dealer.
WARNING - Brake/clutch fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
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.
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, as paint damage will result.
Brake/clutch fluid, which has beenexposed to open air for an extendedtime should never be used as its quality cannot be guaranteed. Itshould be properly disposed. Don't
put in the wrong kind of fluid. A fewdrops of mineral-based oil, such as engine oil, in your brake/clutch sys-tem can damage brake/clutch sys-
tem parts.
