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.

For further brake fluid specification information,
refer to “Capacities and recommended
fuel/lubricants” in the “Technical and consumer
information” section of this manual.
WARNING
●Use only new fluid from a sealed con-
tainer. Old, inferior or contaminated
fluid may damage the brake system.
The use of improper fluids can damage
the brake system and affect the vehi-
cle’s stopping ability.
● Clean the filler cap before removing.
● Brake fluid is poisonous and should be
stored carefully in marked containers
out of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid is
spilled, immediately wash the surface
with water.
BRAKE FLUID
Check the brake fluid level in the reservoir. If the
fluid level is below the MIN line or the brake
warning light comes on, add Genuine NISSAN
Super Heavy Duty Brake Fluid or equivalent DOT
3 fluid up to the MAX line. If fluid must be added
frequently, the system should be checked by an
INFINITI dealer.
WINDOW WASHER FLUID
RESERVOIR
Fill the window washer fluid reservoir periodically.
Add window washer fluid when the low window
washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio.

Refill the reservoir more frequently when driving
conditions require an increased amount of win-
dow washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.
● Do not fill the window washer reservoir
tank with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the window washer reser-
voir tank.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the window washer reservoir tank.
Do not use the window washer reservoir
tank to mix the washer fluid concen-
trate and water. ●
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 discharge.
WARNING
● Do not expose the battery to flames, an
electrical spark or a cigarette. Hydro-
gen gas generated by the battery is ex-
plosive. Explosive gases can cause
blindness or injury. Do not allow battery
fluid to contact your skin, eyes, fabrics
or painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing 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 tip the battery. Keep the vent
caps tight and the battery level. ●
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 bat-
tery life, and in some cases lead to an
explosion.
● When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
● Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
● Keep battery out of the reach of
children.
