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 temperature. 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 betweenF and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use a funnel to help prevent oil frombeing spilled on engine components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci- ties” in section 8.)
WARNING - 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.

Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according tothe Maintenance Schedule at the begin-ning of this section. The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
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
WARNING
Used engine oil may cause irrita- tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughlywith soap and warm water as soon
as possible after handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage and could result in seri-
ous personal injury from escap-ing hot coolant or steam.
(Continued)
(Continued)
Turn the engine off and wait untilit 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. When you aresure 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 operat- ing, do not remove the radiatorcap 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.

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.

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.

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.

Maintenance
CAUTION
Underinflation also results inexcessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If a tire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. Recommended cold tire inflation pressures All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Checking tire inflation pressure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven nomore than 1.6 km (1 mile).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
CAUTION - Tire pressure
Always observe the following:
Check tire pressure when the tires are cold. (After vehiclehas been parked for at leastthree hours or hasn't beendriven more than 1.6 km (one mile) since startup.)
Check the pressure of your spare tire each time you checkthe pressure of other tires.
Never overload your vehicle. Be careful not to overload avehicle luggage rack if your vehicle is equipped with one.
Worn, old tires can cause acci- dents. If your tread is badlyworn, or if your tires havebeen damaged, replace them.
CAUTION
Warm tires normally exceed recommended cold tire pres-sures by 28 to 41 kPa (4 to 6psi). Do not release air fromwarm tires to adjust the pres- sure or the tires will be under-inflated.
Be sure to reinstall the tire inflation valve caps. Withoutthe valve cap, dirt or moisture could get into the valve coreand cause air leakage. If avalve cap is missing, install a new one as soon as possible.
