G030C01JM-AATTo Check the Oil Level
Before checking the oil, warm up the engine to
the normal operating temperature and be sure
your car is parked on level ground. Turn the
engine off.
Wait five minutes, then remove the dipstick,
wipe it off, fully reinsert the dipstick and withdraw
it again. Then note the highest level the oil has
reached on the dipstick. It should be between
the upper ("F") and lower ("L") range.
!
WARNING:
Be very careful not to touch the radiator
hose when checking the engine oil as it may
be hot enough to burn you.
CHECKING THE ENGINE OILG030B01O-AATRecommended Oil
G030C01NF
The engine oil quality should meet the following
classification.
API SJ, SL or ABOVE,
ILSAC GF-3 or ABOVE
G030B01JM-UG030C02NF
(2.4L)(3.3L)NOTE:o For good fuel economy, SAE 5W-20 (5W-
30), ILSAC GF-3 engine oil is preferred
regardless of regional option and en-
gine variation.
o If SAE 5W-20, ILSAC GF-3 engine oil is
not available, secondary recommended
engine oil for corresponding tempera-
ture range can be used.
G030A01A-AATEngine oil is essential to the performance and
service of the engine. It is suggested that you
check the oil level at least once a week in normal
use and more often if you are on a trip or driving
in severe conditions.

CHECKING AND CHANGING THE
ENGINE COOLANT!
G050A01A-AAT
WARNING:
Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is
removed. You could be seriously burned if
you do not observe this precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.
!
5. Remove the oil filter by turning it counter-
clockwise with a oil filter wrench of the proper
size. A certain amount of oil will come out
when you remove the filter. So be sure to
have your drain pan in place underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter itself.
Do not over-tighten.
Tightening torque:
8.7 ~ 11.6 lb.ft (1.2 ~ 1.6 kgf.m)
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Remove the engine oil level dipstick.
8. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It is
suggested that it be placed in a sealed
container and taken to a service station for
reclamation. Do not pour the oil on the
ground or put it into the household trash.
PROPOSITION 65 WARNING:
Used engine oil may cause irritation 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 animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling
used oil.
!
9. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
10.Shut off the engine and recheck the oil level.

CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)G110A01E-AATTransaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.NOTE:Automatic transaxle fluid is basically red in
color. As driving distance increases, the
fluid color turns darkish red gradually. It is
a normal condition and you should not
judge the need to replace based upon the
changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in
section 5.
!
G110B05A-AATRecommended FluidYour Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF SP III, DIAMOND ATF SP III, SK ATF SP
III or other brands meeting the SP III specifica-
tion approved by Hyundai Motor Co.. Damage
caused by a nonspecified fluid is not covered by
your new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may cause
damage to the automatic transaxle.
Only use HYUNDAI GENUINE ATF SP III,
DIAMOND ATF SP III, SK ATF SP III or other
brands meeting the SP III specification ap-
proved by Hyundai Motor Co.. If you are
having your vehicle serviced at a facility
other than a Hyundai dealer, verify that the
correct ATF is used for your vehicle.
G100B02A-AATTo Check the Manual Transaxle
Fluid Level
G100B01L
Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.
2. Use your finger to feel inside the hole. The oil
level should be at its bottom edge. If it is not,
check for leaks before adding oil. To refill the
transaxle or bring the oil level up, add oil
slowly until it reaches the proper level. Do not
overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.

I130B04A-AATTire Quality Grading
Department of Transportation quality
grades - All passenger vehicle tires
must conform to Federal Safety Stan-
dards in addition to these grades. These
quality grades are molded on the
sidewall.
Treadwear - The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under con-
trolled conditions on a specified gov-
ernment test course. For example, a
tire graded 150 would wear one and a
half (1 - 1/2) times as well on the
government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to varia-
tions in driving habits, service prac-
tices and differences in road character-
istics and climate.
