dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.
Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. For manual transmission mod-
els, move the shift lever to N (Neutral).
For automatic transmission models,
move the selector lever to P (Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing, hair and tools away from moving fans, belts
and any other moving parts.
. It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and
the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
MAINTENANCE PRECAUTIONS

CAUTION
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine. Failure to do so could lead to engine
damage.
6. Coat the gasket on the new filter withclean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the
drain plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
See “Capacities and recommended
fuel/lubricants” (P.9-2) for drain and refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these specifi-
cations for reference only. Always use
the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover intoposition as the following steps.
a. Pull the center of the small plastic
clip out.
b. Hold the engine undercover into position.
c. Insert the clip through the under- cover into the hole in the frame, then
push the center of the clip in to lock
the clip in place.
d. Install the other bolts that hold the undercover in place. Be careful not
to strip the bolts or over-tighten
them. 2. Lower the vehicle carefully to the
ground.
3. Dispose of waste oil and filter properly.
WARNING
. Prolonged and repeated contact with
used engine oil may cause skin cancer.
. Try to avoid direct skin contact with used
oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
. Keep used engine oil out of reach of
children.
Maintenance and do-it-yourself8-13

.Keep the battery surface clean and dry.
Clean the battery with a solution of
baking soda and water.
. Make certain the terminal connections
are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the negative
(−) battery terminal cable to prevent
discharging it.
COUPE
CAUTION
When the battery cable is removed from the
battery terminal, do not close either of front
doors. The automatic window adjusting
function will not work, and the side roof
panel may be damaged.
To disconnect the negative (− ) battery
terminal, perform the procedure in the
following order. Otherwise, the window
and the side roof panel may contact and
be damaged.
1. Close the windows.
2. Open the hood.
3. Close and lock all the doors. 4. Disconnect the negative (−
) battery
terminal.
5. Securely close the hood.
To connect the negative (−) battery term-
inal, perform the procedure in the follow-
ing order. Otherwise, the window and the
side roof panel may contact and be
damaged.
1. Unlock and open the driver side door. Do not close the door.
2. Open the hood.
3. Connect the negative (−) battery term- inal. Then close the hood.
4. Fully open the driver side door window.
5. Close the driver side door and the window.
SEDAN AND COUPE
WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics, or painted surfaces. After
touching a battery or battery cap, do not
touch or rub your eyes. Thoroughly wash your hands. If the acid contacts your
eyes, skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
. Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.
. When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
. Keep the battery out of the reach of
children.

BATTERY

CAUTION
.Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.SDI2117
