Maintenance
The following lists are vehicle checks and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle. If you have
any question, we recommend that
you consult an authorized HYUNDAI
dealer.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, levelroad.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check manual transmission opera- tion, including clutch operation.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).

Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

Maintenance
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flash-
ers.
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

Check headlight 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, door and hood drainholes.
Clean and lubricate door hinges and checks, and hood hinges.
Clean and lubricate door and hood locks and latches.
Clean and lubricate door rubber weatherstrips.
Check the air conditioning system.

Maintenance
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual transmission fluid (if equipped)
Inspect the manual transmission fluid according to the maintenance
schedule.
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 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.
Brake discs, 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. (http://brakeman
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.
Power steering pump, belt and hoses
Check the power steering pump and
hoses for leakage and damage.
Replace any damaged or leaking
parts immediately. Inspect the power
steering belt (or drive belt) for evi-
dence of cuts, cracks, excessive
wear, oiliness and proper tension.
Replace or adjust it if necessary.
Air conditioning refrigerant (if equipped)
Check the air conditioning lines and
connections for leakage and dam-
age.

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
