Maintenance
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
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.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.
CAUTION

Maintenance
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 mechan-
ical wear. Inspect all hose connec-
tions, such as clamps and couplings,
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 the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance (Theta 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.
WARNING

7-18
Maintenance
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions.
We recommend that the automatic
transaxle fluid be changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Automatic transaxle fluid colour is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
This is a normal condition and
does not need to be replaced
based on the colour change.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed 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 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 transaxle mal-
function and failure.
Use only specified automatic
transaxle 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.
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 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.
