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
chapter 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:
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always 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 in-
creases, 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 Fluid
Your 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 specification 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 specifi-
cation approved 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.

transaxle is:
WARNING:
The transaxle fluid level should be
checked when the engine is at normal
operating temperature. This means that
the engine, radiator, radiator hose,
exhaust system etc., are very hot.
Exercise great care not to burn yourself

Traction AA, A, B, C - The traction
grades, from highest to lowest, are AA,
A, B, and C. Those grades represent
the tire's ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction per-
formance.
!
WARNING:
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not in-
clude acceleration, cornering, hy-
droplaning, or peak traction charac-
teristics.
CONSUMER INFORMATION
(U.S.A only)I130A01A-AATThis consumer information has been
prepared in accordance with regulations
issued by the National Highway Traffic
Safety Administration of the U.S.
Department of Transportation. It provides
the purchasers and/or prospective
purchasers of Hyundai automobiles with
information on uniform tire quality grading.
Your Hyundai dealer will help answer any
questions you may have as you read this
information.
I130B04A-AATTire Quality GradingQuality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATUE ATreadwear - 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.
