F060E01A-AATo Timing belt
Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-
aged parts immediately.
F070D01A-AATo Manual transaxle oil
Inspect the manual transaxle oil according to
the maintenance schedule.
NOTE:If the oil level is low, check for possible leaks
before adding oil. Do not overfill.
F070E05A-AAT
o Automatic Transaxle Fluid
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
running and the transaxle in neutral, with the
parking brake properly applied. Use HYUNDAI
GENUINE ATF, DIAMOND ATF SP-III or SK
ATF SP-III when adding or changing fluid.
F070G02A-AAT
o Brake Fluid
Check brake fluid level in the brake fluid reser-
voir. The level should be between "MIN" and
"MAX" marks on the side of the reservoir. Use
only hydraulic brake fluid conforming to DOT 3
or DOT 4.
F070F01A-AAT
o Brake Hoses and Lines
Visually check for proper installation, chafing,
cracks, deterioration and any leakage. Replace
any deteriorated or damaged parts immedi-
ately.
F070H01A-AAT
o Rear Brake Drums/Linings,
Parking Brake
Check the rear brake drums and linings for
scoring, burning, leaking fluid, broken parts,
and excessive wear. Inspect the parking brake
system including the parking brake lever and
cables. For detailed service procedures, refer
to the Shop Manual.
F070J01A-AATo Brake Pads, Calipers and Rotors
Check the pads for excessive wear, discs for
run out and wear, and calipers for fluid leakage.
F070K01A-AATo Exhaust Pipe and Muffler
Visually inspect the exhaust pipes, muffler and
hangers for cracks, deterioration, or damage.
Start the engine and listen carefully for any
exhaust gas leakage. Tighten connections or
replace parts as necessary.
F060B01A-AAT
o Drive Belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension and
adjusted as necessary.
F070C01A-AAT
o Engine coolant
The coolant should be changed at the intervals
specified in the maintenance schedule.

4CHECKING THE ENGINE OIL
G030A01A-AAT
Engine 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.
G030C01A-AAT
To 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 a minute, 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 ("FULL") and lower ("LOW") range.
G030B02E-AAT
Recommended Oil
SH(API) or GF-I (ILSAC) and ABOVE multi-
grade and fuel efficient oil is recommended.

6CHECKING 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. Oil filter tightening torque :
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. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
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.

Adding Brake Fluid
WARNING:
Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
HXDFL012
CHECKING THE CLUTCH FLUID
G130A01S-AAT
To Check the Clutch Fluid
The clutch fluid level in the master cylinder
should be checked when performing other un-
der hood services. The system should be
checked for leakage at the same time.
Check to make certain that the clutch fluid level
is always between the "MAX" and "MIN" level
markings on the fluid reservoir. Fill as required.
Fluid loss indicates a leak in the clutch system
which should be inspected and repaired imme-
diately. Consult your Hyundai dealer. To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.

from the norm due to variations in driving habits,
service practices and differences in road char-
acteristics and climate.
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
pavement as measured under controlled con-
ditions on specified government test surfaces
of asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING:The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B, C - The temperature grades
are A (the highest), B, and C, representing the
tire's resistance to the generation of heat and
its ability to dissipate heat when tested under
controlled conditions on a specified indoor labo-
ratory test wheel. Sustained high temperature
can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which all
WARNING:The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.

Uniform Tire Quality Grading - Quality grades
can be found on the tire sidewall between the
tread shoulder and the maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A passenger car tires must meet under the Fed-
eral Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
