Maintenance
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
✽✽NOTICE
If the oil level is low, check for possible
leaks before adding oil. Do not overfill.
Automatic transaxle fluid (if equipped)
The fluid level should be in the "HOT"
range of the dipstick, after the engine
and transaxle are at normal operating
temperature. Check the automatic
transaxle fluid level with the engine run-
ning and the transaxle in neutral, with the
hand brake properly applied. Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately. Brake fluid

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 (at least 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 refill the new oil com-
fortably.
Use only the specified engine oil. (Refer to the 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.

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorised 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
- 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.
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

Maintenance

7
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 and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorised
Hyundai dealer for a cooling systeminspection.
Recommended engine coolant
Use only soft (de-mineralised) 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.
Changing the coolant
Have coolant changed by an authorised Hyundai dealer according to theMaintenance Schedule at the beginningof this section.

BRAKE AND 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, have
the brake system checked by an autho-
rised Hyundai dealer.
Use only the specified brake/clutch fluid.
(Refer to the section 8.)
Never mix different types of fluid.
WARNING - Brake 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
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor 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 authorised Hyundai dealer.
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's body paint, as paint damage will result.
Brake/clutch fluid, which has been exposed to open air for an extendedtime should never be used as itsquality cannot be guaranteed. Itshould be thrown out. Don't put in
the wrong kind of fluid. A few dropsof mineral-based oil, such as engine oil, in your brake clutch sys-tem can damage brake clutch sys-
tem 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 hand brake applied and check the
fluid level according to the following pro-
cedure.
1. Place the selector 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 positions then place the
selector 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
from 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 “COLD” line
and then recheck the fluid level
according to the above step 2.

✽✽NOTICE
“COLD” scale is for reference only and
should NOT be used to determinetransaxle fluid level. ✽
✽
NOTICE
New automatic transaxle fluid should be
red. The red dye is added so the assem-bly plant can identify it as automatic
transaxle fluid and distinguish it from
engine oil or antifreeze. The red dye,
which is not an indicator of fluid quali-
ty, is not permanent. As the vehicle isdriven, the automatic transaxle fluid
will begin to look darker. The color may
eventually appear light brown.
Therefore, have an authorised Hyundai
dealer change the automatic transaxlefluid according to the ScheduledMaintenance at the beginning of thissection.
Use only the specified automatic
transaxle fluid. (Refer to the section 8.)
Changing the automatic transaxle fluid
Have automatic transaxle fluid changed
by an authorised Hyundai dealer accord-ing to the Maintenance Schedule at thebeginning of this section.
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.
WARNING - Hand brake
To avoid sudden movement of the
vehicle, apply hand brake and
depress the brake pedal before
moving the shift lever.
CAUTION
Low fluid level causes transaxle slippage. Overfilling can causefoaming, loss of fluid and transaxle malfunction.
The use of a non-specified fluid could result in transaxle malfunc-tion and failure.

Replace the filter according to the Scheduled Maintenance Section.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual recom-mended intervals. (Refer to“Maintenance under severe usage condi-
tions” in this section.)
CAUTION
Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirt
does not enter the air intake, ordamage may result.
Use a Hyundai genuine part. Use of nongenuine part could damagethe air flow sensor or turbo charg-
er.
