Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make sure all
warning lights and chimes are operating properly.
Windshield wiper and washer* Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake fluid level* Make sure that the brake fluid
level is between the MIN and MAX lines on the
reservoir.
Engine coolant level* Check the coolant level
when the engine is cold. Engine drive belts*
Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust system Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaks Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water 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 imme-
diately.
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 ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid* Check that there is
adequate fluid in the reservoir.

5. Wipe the engine oil filter sealing surface witha clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to an
oil leak and engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw on the oil filter until a slight resistance is felt, then tighten an additional 2/3 turn.
8. Start the engine and check for leakage around the oil filter. Correct as required.
9. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine oil if
necessary. When checking or replacement is required, we
recommend your INFINITI dealer for servicing.
CAUTION
●
Use Genuine NISSAN Matic S ATF. If
Genuine NISSAN Matic S ATF is not
available, Genuine NISSAN Matic J ATF
may also be used.
● Using automatic transmission fluid
other than Genuine NISSAN Matic S
ATF or Matic J ATF will cause deteriora-
tion in driveability and automatic trans-
mission durability, and may damage the
automatic transmission, which is not
covered by the INFINITI new vehicle lim-
ited warranty.
The specified automatic transmission fluid is also
described on caution labels located in the engine
compartment. The fluid level should be checked using the HOT
MAX range on the power steering fluid reservoir
at fluid temperatures of 122° - 176°F (50° -
80°C) or using the COLD MAX range on the
power steering fluid reservoir at fluid tempera-
tures of 32° - 86°F (0° - 30°C) .
If the fluid is at or below the MIN line, add Genu-
ine NISSAN PSF to HOT MAX or COLD MAX
depending on system fluid temperature. Remove
the cap and fill through the opening.
CAUTION
●
DO NOT OVERFILL.
● Recommended fluid is Genuine
NISSAN PSF or equivalent.

CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator. The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.

WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
