Maintenance
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stop lamps,
turn signals and hazard warning
flashers.
• Check the inflation pressures of all
tires including the spare.
At least twice a year
(i.e., every Spring and Fall) :
• Check radiator, heater and air con-
ditioning hoses for leaks or dam-
age.
• Check windshield washer spray
and wiper operation. Clean wiper
blades with clean cloth dampened
with washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes,
shields and clamps.
• Check the lap/shoulder belts for
wear and function.
• Check for worn tires and loose
wheel lug nuts.
At least once a year :
• Clean body and door drain holes.
• Lubricate door hinges and checks,
and hood hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather-
strips.
• Check the air conditioning system.
• Inspect and lubricate automatic
transmission linkage and controls.
• Clean battery and terminals.
• Check the brake fluid level.

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 an authorized
HYUNDAI dealer.
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 an authorized
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.

Maintenance
ENGINE OIL
Checking the engine oil level
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 re-insert it fully.5. Pull the dipstick out again and
check the level. The level should
be between F and L.
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
WARNING •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 room, wipe it off
immediately.
•When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.

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 traveling
to a colder climate.Checking the coolant level
Removing radiator
cap
•
Never attempt to remove the
radiator cap while 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 while
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
while 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

Radiator cap
Do not remove the
radiator cap when the
engine and radiator
are hot. Scalding hot
coolant and steam
may blow out under
pressure causing seri-
ous injury.
WARNING
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 vehicle
control or damage to paint
and body trim.
WARNING
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as generator.

Maintenance
WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.

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 vehicle
control or damage to paint
and body trim.
•Windshield Washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
•Windshield washer fluid is
poisonous to humans and
animals. Do not drink and
avoid contacting windshield
washer fluid. Serious injury or
death could occur.
