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.

the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.●Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.

borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the trim panel near the accelera-
tor pedal. Refer to the “NISSAN Service and

If you wax the surface of the hood, be careful not
to let wax get into the washer nozzle
A. This may
cause clogging or improper windshield washer
operation. If wax gets into the nozzle, remove it
with a needle or small pin

check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
