Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly 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 movingcomponent 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 isreplaced. Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer 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. Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated 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 3 or DOT 4specification.

Automatic transmission fluid It is recommended that the automatic
transmission fluid should be checked by
an authorized HYUNDAI dealer.
In severe conditions, the fluid should be
changed at an authorized HYUNDAIdealer in accordance to the scheduledmaintenance at the beginning of this
chapter. 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 damage.
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 immedi-
ately. Inspect the power steering belt (or
drive belt) for evidence of cuts, cracks,
excessive wear, oiliness and proper ten-
sion. Replace or adjust it if necessary.Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air conditioning refrigerant (if equipped)
Check the air conditioning lines and con-
nections for leakage and damage.
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage. Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
CAUTION
The use of a non-specified fluid
could result in transmission mal-function and failure.
Use only specified automatic trans-mission fluid. (Refer to
“Recommended lubricants andcapacities” in section 8.)

Changing the coolant
Have coolant changed by an authorized
HYUNDAI dealer according to theMaintenance Schedule at the beginningof this section.
WARNING - Radiator cap
Do not remove the radiator cap when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
CAUTION
Put a thick cloth around the radiator cap before refilling the coolant in
order to prevent the coolant fromoverflowing into engine parts suchas the generator.
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.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir. Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants or capaci- ties” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. Ifbrake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
CAUTION
Do not allow brake fluid to contact the vehicle's body paint, as paintdamage will result. Brake fluid, which has been exposed to open airfor an extended time should never
be used as its quality cannot be guaranteed. It should be disposedof properly. Don't put in the wrong kind of fluid. A few drops of miner-
al-based oil, such as engine oil, in your brake system can damagebrake system parts.

POWER STEERING FLUID
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the gauge at the normal tempera-
ture. Before adding power steering fluid, thor-oughly clean the area around the reser-
voir cap to prevent power steering fluidcontamination.
If the level is low, add fluid to the MAX
level.
In the event the power steering system requires frequent addition of fluid, the
vehicle should be inspected by an
authorized HYUNDAI dealer.
Use only the specified power steering
fluid. (Refer to "Recommended lubricants
or capacities" in section 8.)
Checking the power steering hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering water pump unit, do not
operate the vehicle for prolonged periods with a low power steeringfluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering
system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.

Maintenance
Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visualinspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. 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.
WASHER FLUID
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.
Windshield Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.
