If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
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 ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching 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,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.
Two types of fuses are used. Type

partment. Type

compartment fuse box.
Type
OAfuses are provided as spare fuses.
They are stored in the passenger compart-
ment fuse box.
Type

compartment and passenger compart-
ment fuse boxes.

If a typeOAfuse is used to replace a typeOB
fuse, the typeOAfuse will not be level with
the fuse pocket as shown in the illustration.
This will not affect the performance of the
fuse. Make sure the fuse is installed in the
fuse box securely.
Type
OBfuses cannot be installed in the
underhood fuse boxes. Only use type
OA
fuses in the underhood fuse boxes.
NOTE:
Your vehicle may not be equipped with
all fuses listed on the fuse label.
