1.%),204/3424-3$$ " !"##$$# !"$" "$#!$Engine oil and filterThe 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 frequent oil and filter changes
are required.Drive beltsInspect 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.When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.
Fuel filterA 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 authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nectionsCheck 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 authorized HYUNDAI
dealer.
NOTICE
Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectors
and high pressure pipes are sub-
ject to high pressure even a fter
the engine stopped. The fuel jet
produced by fuel leaks may cause
serious injury, if it touch the b ody.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
eng ine room while engine is run-
ning, since the high currents in the
Common Rail system produce
considerab le magnetic fields.

VVapor hose and fuel filler capThe vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor 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 filterWe recommend that the air cleaner
filter be replaced by an authorized
HYUNDAI dealer.Spark plugsMake sure to install new spark plugs
of the correct heat range.Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.
WARNING

1.%#,204/3424-3CCooling systemCheck cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.CoolantThe coolant should be changed at
the intervals specified in the mainte-
nance schedule.Manual transaxle fluid
(if equipped)Inspect the manual transaxle fluid
according to the maintenance sched-
ule.
Continuously Variable Transaxle
fluid (if equipped)Continuously Variable Transaxle fluid
should not be checked under normal
usage conditions.
But, the Continuously Variable
Transaxle fluid should be changed
under severe usage conditions. We
recommend that the Continuously
Variable Transaxle fluid changed by
an authorized HYUNDAI dealer
according to the maintenance sched-
ule. (Refer to “Maintenance Under
Severe Usage Conditions” in this
chapter. )
Information
Continuously Variable Transaxle fluid
color is basically light amber.
As the vehicle is driven, the
Continuously Variable 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.
The use of non-specified fluid (even
marked as compatible with genuine)
could result in shift quality d eteriora-
tion and vibrations, eventually, the
transaxle failure.
Use only specified Continuously
Variabl e Transaxle fluid. (Refer to
"Recommended lubricants and
capacities" in chapter 8.)Brake hoses and linesVisually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.Brake fluidCheck brake fluid level in the brake
fluid reservoir. The level should be
between "MIN" (Minimum) and
"MAX" (Maximum) marks on the side
of the reservoir. Use only hydraulic
brake fluid conforming to DOT 3 or
DOT 4 specification.NOTICE

PParking brakeInspect the parking brake system
including the parking brake pedal
and cables. Brake discs, pads, calipers and
rotorsCheck the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.Suspension mounting boltsCheck 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 dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or damage. Replace any damaged
parts.
Drive shafts and bootsCheck the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.Air conditioning refrigerant
(if equipped)Check the air conditioning lines and
connections for leakage and dam-
age.

1.%',204/3424-3$$"!"$#!Checking the engine oil level
(Petrol engiene)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 reinsert it fully.
5.Pull the dipstick out again and check the level. The level should be
between F (Full) and L (Low). If it is near or at L (Low), add enough
oil to bring the level to F (Full).
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 lubricantsand capacities" in chapter 8.)
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as i t may be
hot enough to burn you.
WARNING
OIB074004
OIB074006
•
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 ro om, wipe it off immedi-
ately.
•
When you wipe the oil level
gauge, you should wipe it with a
clean cloth. When mixed with
debris, it can cause engine dam-
age.
CAUTION

1.+),204/3424-3CChanging the coolantWe recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.Put a thick cloth or fabric around the
radiator cap before refilling the
coolant in order to prevent the
coolant from overflowing into engine
parts such as the alternator.NOTICE
Coolant•
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
•
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of ve hicle control or
damage to paint and body trim.
