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-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause hard
starting. When a considerable
amount of foreign substances are
accumulate in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the diesel engine for several min-
utes, and check the connections for
any leakages. We recommend that
you have the fuel filter 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. When you are inspecting the
drive belt, place the ignition
switch to the LOCK/OFF or ACC
position.
CAUTION
Diesel Only
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning the diesel
engine OFF. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine.
When the fuel leakage vents
out, it may cause serious body
injury. Any people, who are
implemented with the artificial
cardiac pacemaker, should
remain away from the ECU or
the wiring harness by at least 30
cm whilst running the diesel
engine. The high currents of the
common rail system produce a
considerable amount of mag-
netic fields.
WARNING

7-28
Maintenance
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 assure
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.
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.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Automatic transmission fluid
colour is basically red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
It is normal condition and you
should not judge the need to
replace the fluid based upon the
colour change.
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
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 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 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever (or
pedal) and cables.
NOTICE
The use of a non-specified fluid
could result in transmission
malfunction and failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)
CAUTION

Maintenance
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 box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
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. Be sure the vehicle is on level
ground.2. Start the engine and allow it to
reach normal operating tempera-
ture.
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.

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.
WARNING
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 the engine compartment,
wipe it off immediately.
When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.
CAUTION

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 com-
ponents.
Use only the specified engine oil.

Used engine oil may cause irri-
tation 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 lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soap
and warm water as soon as pos-
sible after handling used oil.
