classification.
API SJ, SL or ABOVE,
ILSAC GF-3 or ABOVE
G030B01JM-U G030A01A-AAT

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.
G030C01NF
G030C02NF
(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.

G030D01O-AATAdding Oil
1. Remove the oil filler cap by turning it counter-
clockwise.
2. Add oil, then check the level again. Do not
overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks is
equal to about 1 quart of oil.
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
WARNING:
Be very careful not to touch the radiator
hose when adding the engine oil as it may
be hot enough to burn you.
If the oil level is close to or below the "L" mark,
add oil until it reaches the "F" mark. To add oil:

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:
This product contains a chemical known to
the State of California to cause cancer.
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.

CAUTION:
o Radiator antifreeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.
!
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during bad weather or
whenever the washer system is in more fre-
quent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (4.0 liters).
!
WARNING:
It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.

CHECKING THE BATTERY!
G210A01A-AAT
WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solution
of sulfuric acid, which is poisonous and highly
corrosive. Be careful not to spill it on yourself or
the car. If you do spill battery fluid on yourself,
immediately do the following:
HNF5017
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle's generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in
the area.
o Keep children away from the area.
!
G210B04A-AATChecking the BatteryKeep the battery clean. Any evidence of corro-
sion around the battery posts or terminals
should be removed using a solution of house-
hold baking soda and warm water. After the
battery terminals are dry, cover them with a light
coating of grease.
PROPOSITION 65 WARNING:
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and reproductive harm.
Batteries also contain other chemicals
known to the state of California to cause
cancer. Wash hands after handling.

G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power steer-
ing hose connections for fluid leakage at those
intervals specified in the vehicle maintenance
schedule in Section 5.
The power steering hoses should be replaced
if there is severe surface cracking, pulling,
scuffing or worn spots. Deterioration of the hose
could cause premature failure.
POWER STEERING FLUID LEVELG230A01NF-AAT
to make certain that the power steering fluid
level is between the "MAX" and "MIN" level
markings on the fluid reservoir.NOTE:Grinding noise from the power steering
pump may be heard immediately after the
engine is started in extremely cold condi-
tions (below - 4°F). If the noise stops during
warm up, there is no abnormal function in
the system. It is due to a power steering
fluid characteristic in extremely cold condi-
tions.
Recommended Fluid
Use PSF-4 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.
