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.
