[ Edit: 2012/ 1/ 17 Model: V36-D ]8-6 Maintenance and do-it-yourselfdripping 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. GUID-DA5BC1C7-4A3F-402D-B20E-D7AF3C2C5866
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

SEDAN AND COUPE GUID-58FD0A1C-91D1-47E9-8C3E-221C89D57EFE
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.

Check the fluid level in each cell (Remove
the battery cover if it is necessary). It
should be between the UPPER LEVEL
* 1
and LOWER LEVEL
* 2
lines.
If it is necessary to add fluid, add only
distilled water to bring the level to the
indicator in each filler opening. Do not
overfill. SDI1480C
1. Remove the cell plugs

.
2. Add distilled water up to the UPPER
LEVEL

line.
If the side of the battery is not clear,
check the distilled water level by
looking directly above the cell; the
condition

Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level. JUMP STARTING GUID-6645B036-2286-48B9-B8ED-5E16B522CC2D

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. GUID-2598C543-2A3B-4E05-90F6-3739930B5F0C
