Maintenance work
•Performing maintenance work
on a vehicle can be danger-
ous. You can be seriously
injured whilst performing
some maintenance proce-
dures. If you lack sufficient
knowledge and experience or
the proper tools and equip-
ment to do the work, we rec-
ommend that the system be
serviced by a HYUNDAI autho-
rised repairer.
•Working under the bonnet
with the engine running is
dangerous. It becomes even
more dangerous when you
wear jewellery or loose cloth-
ing.
(Continued)
WARNING (Continued)
These can become entangled
in moving parts and result in
injury. Therefore, if you must
run the engine whilst working
under the bonnet, make cer-
tain that you remove all jew-
ellery (especially rings,
bracelets, watches, and neck-
laces) and all neckties,
scarves, and similar loose
clothing before getting near
the engine or cooling fans.
•Do not put heavy objects or
apply excessive force on top of
the engine cover (if equipped)
or fuel related parts.
•When you inspect the fuel
system (fuel lines and fuel
injection devices), we recom-
mend that you contact a
HYUNDAI authorised repairer.
(Continued)
CAUTION
(Continued)
•Do not drive long time with
the engine cover (if equipped)
removed.
•When checking the engine
room, do not go near fire. Fuel,
washer fluid, etc. are flamma-
ble oils that may cause fire.
•Before touching the battery,
ignition cables and electrical
wiring, you should disconnect
the battery "-" terminal. You
may get an electric shock
from the electric current.
•When you remove the interior
trim cover with a flat head (-)
driver, be careful not to dam-
age the cover.
•Be careful when you replace
and clean bulbs to avoid
burns or electrical shock.

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
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 a HYUNDAI
authorised repairer.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(3.0L / 3.3L / 3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by a HYUNDAI autho-
rised repairer.
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

Maintenance
ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate.Checking the coolant level
Removing radiator
cap
•
Never attempt to remove the
radiator cap whilst the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
•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.
(Continued)
WARNING
(Continued)
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 oper-
ating, do not remove the radi-
ator 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.
•When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
•Do not drive with no engine
coolant. It may cause water
pump failure and engine
seizure, etc.
CAUTION

Maintenance
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
distilled (deionised) or soft water.
Bring the level to F (MAX), but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by a HYUNDAI authorised
repairer.
Recommended engine coolant
• When adding coolant, use only
deionised water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified 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.
ODH073004
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blade. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
