2008 NISSAN SENTRA Owners Manual

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
cDo not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the paint.
cDo 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.
cPre-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.cKeep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
cMake certain the terminal connections are
clean and securely tightened.
cIf the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
WARNING
cDo not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics or painted surfaces. After
touching 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.
cDo 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.cWhen working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
cBattery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
cKeep battery out of the reach of
children.

The in-cabin microfilter restricts the entry of air-
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
Maintenance Guide” for change intervals.

in a washer solution or a mild detergent. Then
rinse the blades with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.

age the windshield and impair driver

CAUTION
cAfter wiper blade replacement, return
the wiper arm to its original position;
otherwise it may be damaged when the
hood is opened.
cMake sure the wiper blades contact the
glass; otherwise the arms may be dam-
aged from wind pressure.
If you wax the surface of the hood, be careful not
to let wax get into the washer nozzle
sA. This may
cause clogging or improper windshield washer
operation. If wax gets into the nozzle, remove it
with a needle or small pin
sB.If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
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.
