8-6Maintenance and do-it-yourself
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.

8-14Maintenance and do-it-yourself
When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
. Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will
cause deterioration in driveability and
automatic transmission durability, and
may damage the automatic transmis-
sion, which is not covered by the INFINITI
new vehicle limited warranty.
SDI1765A
Check the fluid level in the reservoir.
The fluid level should be checked using the
HOT range (
*1: HOT MAX.,*2: HOT MIN.)
at fluid temperatures of 122 to 1768F (50
to 808C) or using the COLD range (
*3:
COLD MAX.,
*4: COLD MIN.) at fluid
temperatures of 32 to 868F(0to30 8C).
If the fluid is below the MIN line, add
Genuine NISSAN PSF or equivalent. Re-
move the cap and fill through the opening.
CAUTION
. Do not overfill.
. Use Genuine NISSAN PSF or equivalent.
AUTOMATIC TRANSMISSION FLUID POWER STEERING FLUID
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
