1: Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or replace.
*2: Check the engine oil level for leaks every 500 km or before starting a long trip.
*3 : The engine oil level should be checked regularly and maintained properly. Operating with an insufficient amount of oil can dam-
age the engine, and such damage is not covered by warranty.
*
4: 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 recommends "every
7,500km inspection, every 15,000km replacement". If there are some important safety matters like fuel flow restriction, surg-
ing, loss of power, hard starting problem etc., replace the fuel filter immediately regardless of maintenance schedule. We rec-
ommend that you consult an authorised 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
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
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 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.
We recommend that the fuel filter be
replaced by an authorised HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorised HYUNDAI
dealer.
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 that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage. When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
CAUTION

Maintenance
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
(for Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for Petrol Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorised HYUNDAI
dealer.
Cooling system
Check the cooling system parts,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid is changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Information
Automatic transmission fluid colour is
red when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the colour
change.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic
transmission fluid.
(Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
Dual clutch transmission fluid
(if equipped)
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch fluid
(if equipped)
Check the brake/clutch fluid level in
the brake/clutch fluid reservoir. The
level should be between “MIN” and
“MAX” marks on the side of the
reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT
4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever (or
pedal) and cables.
Brake pads, calipers and
rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear rack, 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 dam-
age. 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 necessary, repack the
grease.
Air conditioning refrigerant/
compressor
Check the air conditioning lines and
connections for leakage and dam-
age.

Checking the engine oil level
(Petrol engine)
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set. If possible, block the
wheels.
3. Turn the engine on and allow the
engine to reach normal operating
temperatures.
4. Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
5. Pull the dipstick out, wipe it clean,
and re-insert it fully.6. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low).7. If it is near or at L, add enough oil
to bring the level to F. Do not over-
fill.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)

Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding engine oil as it may be
hot enough to burn you.

Maintenance
To prevent damage to your engine:
Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
Do not spill engine oil when
adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.
