Owner maintenance precautions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section, sev-
eral procedures can be done only by a
HYUNDAI authorised repairer with spe-
cial tools.
✽NOTICE
Improper owner maintenance during
the warranty period may affect warran-
ty coverage. For details, read the sepa-
rate Service Passport provided with the
vehicle. If you're unsure about any serv-
icing or maintenance procedure, have it
done by a HYUNDAI authorised repair-
er.
WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by a
HYUNDAI authorised repairer.
• Working under the bonnet with
the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.
WARNING- Diesel Engine
Never work on injection system
with the engine running or within
30 seconds after shutting off the
engine. High-pressure pump, rail,
injectors and high-pressure pipes
are subject to high pressure even
after the engine stopped. The fuel
jet produced by fuel leaks may
cause serious injury, if it touches
the body. People using pacemakers
should not move than 30cm closer
to the ECU or wiring harness within
the engine room whilst engine is
running, since the high currents in
the electronic engine control sys-
tem produce considerable magnet-
ic fields.

Maintenance
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 fuel
filler 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 moving
component 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
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
A HYUNDAI authorised repairer should
perform the operation.
Cooling system
Check cooling system components, 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.

Maintenance
Changing the engine oil and filter
Have the engine oil and filter changed by
a HYUNDAI authorised repairer accord-
ing to the Maintenance Schedule.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 level at least once a year, at the
beginning of the winter season, and
before travelling to a colder climate.

WARNING- Removing
radiator cap
• Never attempt to remove the radi-
ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage. Also hot coolant
or steam could cause serious
personal injury.
(Continued)
(Continued)
• 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. Step back whilst
the pressure is released from the
cooling system. When you are
sure all the pressure 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 radiator
cap 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
Prolonged and repeated contact
with used engine oils may result in
serious skin disorders including
dermatitis and cancer. Avoid con-
tact with skin as far as possible and
always wash thoroughly after any
contact. Keep used oils out of
reach of children. It is illegal to pol-
lute drains, water courses and soil.
Use only authorised waste collec-
tion facilities including civic ameni-
ty sites and garages for the dispos-
al of used oil and oil filters. If in
doubt, contact the local authority
for disposal instructions.

Maintenance
14 7
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 (Full) and L (Low) marked on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (Full), but do not overfill. If fre-
quent additions are required, see a
HYUNDAI authorised repairer for a cool-
ing system inspection.
Recommended engine coolant
• Use only soft (distilled) water in the
coolant mixture.
• 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 specified
coolant.
• 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.
