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 between F 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 capac-ities” in chapter 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.

ENGINE COOLANT
Changing the engine oil and filter
We recommend that the engine oil and
filter be replaced by an authorized
HYUNDAI dealer. 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 skin irri- tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possibleafter handling used oil.
WARNING
Removing radiatorcap
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.
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. 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.

Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill.
If frequent additions are required, we rec-
ommend that the system be inspected by
an authorized HYUNDAI dealer.
Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.(Continued)
Even if the engine is not operat- ing, do not remove the radiator 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.
WARNING
The electric motor (cool-
ing fan) is controlled byengine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate evenwhen 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 the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.

Maintenance
Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
CAUTION
Put a thick cloth around the radiatorcap before refilling the coolant in order to prevent the coolant from overflowing into the engine partssuch as 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.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.

BRAKES/CLUTCH(IF EQUIPPED) FLUID
Checking the brake/clutch 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/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch 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, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants and capacities” in chapter 8.)
Never mix different types of fluid.
WARNING - Brake/clutch fluid
When changing and adding
brake/clutch fluid, handle it careful-
ly. Do not let it come in contact with
your eyes. If brake/clutch fluid
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,we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, aspaint damage will result.Brake/clutch fluid, which has been
exposed to open air for an extended time should never be used as itsquality cannot be guaranteed. It should be properly disposed. Don't
put in the wrong kind of fluid. A few drops of mineral-based oil, such asengine oil, in your brake/clutch sys-tem can damage the system parts.

AUTOMATIC TRANSAXLE FLUID (IF EQUIPPED)
Checking the automatic transaxle
fluid level
The automatic transaxle fluid level
should be checked regularly.
Keep the vehicle on the level ground with
the parking brake applied and check the
fluid level according to the following pro-
cedure.
1. Place the shift lever in N (Neutral) position and confirm the engine is run-
ning at normal idle speed.
2. After the transaxle is warmed up suffi- ciently (fluid temperature 70~80°C
(158~176°F), for example by 10 min-
utes usual driving, move the shift leverthrough all the positions then place the
shift lever in “N (Neutral) or P (Park)”position. 3. Confirm that the fluid level is in “HOT”
range on the level gauge. If the fluid
level is lower, add the specified fluid in
the fill hole. If the fluid level is higher,
drain the fluid from the drain hole.
4. If the fluid level is checked in cold con- dition (fluid temperature 20~30°C
(68~86°F) add the fluid to “C” (COLD)
line and then recheck the fluid level
according to the above step 2.
OBA073007OHD076045N
WARNING - Transaxle fluid
The transaxle fluid level should be
checked when the engine is at nor-
mal operating temperature. This
means that the engine, radiator,
radiator hose and exhaust system
etc., are very hot. Exercise great
care not to burn yourself during
this procedure.

✽✽
NOTICE
“C” (COLD) range is for reference only
and should NOT be used to determine
the transaxle fluid level. ✽
✽
NOTICE
A new automatic transaxle fluid should
be red. The red dye is added so the
assembly plant can identify it as auto-
matic transaxle fluid and distinguish it
from engine oil or antifreeze. The red
dye, which is not an indicator of fluid
quality, is not permanent. As the vehicle
is driven, the automatic transaxle fluid
will begin to look darker. The color may
eventually appear light brown.
Therefore, we recommend that the sys-
tem be replaced by an authorized
HYUNDAI dealer according to the
Scheduled Maintenance at the begin-
ning of this chapter.
Use only the specified automatic
transaxle fluid. (Refer to “Recommended
lubricants and capacities” in chapter 8.) Changing the automatic transaxle fluid
We recommend that the system be
replaced by an authorized HYUNDAI
dealer.
WARNING
- Parking brake
To avoid sudden movement of the
vehicle, apply the parking brake
and depress the brake pedal before
moving the shift lever.
CAUTION
Low fluid level causes transaxle shift slippage. Overfilling can
cause foaming, loss of fluid andtransaxle malfunction.
The use of a non-specified fluid could result in transaxle malfunc-
tion and failure.
