Maintenance work
Performing maintenance work
on a vehicle can be danger-
ous. You can be seriously
injured while 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 an authorized
HYUNDAI dealer.
Working under the hood with
the engine running is danger-
ous. It becomes even more
dangerous when you wear
jewelry or loose clothing.These can become entangled
in moving parts and result in
injury.(Continued)
WARNING Continued)
Therefore, if you must run the
engine while working under
the hood, make certain that
you remove all jewelry (espe-
cially rings, bracelets, watch-
es, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or coolingfans.
Do not put heavy objects or
apply excessive force on top
of the engine cover (ifequipped) or fuel related
parts.
When you inspect the fuel system (fuel lines and fuel
injection devices), we recom-
mend that you contact an
authorized HYUNDAI dealer.
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
flammable 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. (Continued)

Maintenance
Vapor hose and fuel filler cap
The 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 whichmight 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 authorized
HYUNDAI dealer.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.

7-24
Maintenance
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
level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate.Checking the coolant level
EENN GGIINN EE CC OO OOLLAA NN TT

Do not drive with no engine
coolant. It may cause waterpump failure and engine
seizure, etc.
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 insmall quantities.
CAUTION
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing somight lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hotcoolant 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 while
the pressure is released fromthe 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 plugwhile the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.

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 and L marks on the side
of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
Recommended engine coolant
When adding coolant, use onlydeionized 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 corrosionand 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 thesolution.
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 blades. As theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.WARNING
