Warning lights and chimes:Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washers operate properly and that
the wipers do not streak.
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.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level.
Brake and clutch fluid levels*: Make sure that
the brake and clutch fluid levels are between
the MAX and MIN lines on the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belt*: Make sure that the drive belt
is not frayed, worn, cracked or oily. Engine oil level*:
Check the level after parking
the vehicle on a level surface and turning off the
engine. Wait more than 15 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 retailer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
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 cor-
rected immediately.
Power steering fluid level* and lines: Check the
level 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, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

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 transmission, which is not
covered by the INFINITI new vehicle limited
warranty. Check the fluid level in the reservoir.
The fluid level should be checked with the
engine off using the HOT range (
1: HOT MAX.,
2: HOT MIN.) at fluid temperatures of 122 to
176°F (50 to 80°C) or using the COLD range (
3:
COLD MAX.,
4: COLD MIN.) at fluid tempera-
tures of 32 to 86°F (0 to 30°C).
If the fluid is below the MIN line, add Genuine
NISSAN PSF or equivalent. Remove the cap and
fill through the opening.
CAUTION
● Do not overfill.
● Use Genuine NISSAN PSF or equivalent. For further brake and clutch fluid information,
see “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section of this manual.
WARNING
●
Use only new fluid from a sealed container.
Old, inferior or contaminated fluid may dam-
age the brake system. The use of improper
fluids can damage the brake system and af-
fect the vehicle’s stopping ability.
● Be sure to clean the filler cap before
removing.
● Brake fluid is poisonous and should be
stored carefully in marked containers out of
the reach of children.
CAUTION
Do not spill the fluid on painted surfaces. This
will damage the paint. If fluid is spilled, wash
the surface with water.

JUMP STARTING
If jump starting is necessary, see “JUMP START-
ING” in the “6. In case of emergency” section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact an
INFINITI retailer.
CAUTION
●Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.
1. Power steering fluid pump
2. Alternator
3. Crankshaft pulley
4. Air conditioner compressor
5. Drive belt auto-tensioner
WARNING
Be sure the ignition switch is in the OFF or LOCK
position before servicing the drive belt. The
engine could rotate unexpectedly.
