Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as

platinum-tipped spark plugs by cleaning or re-
gapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.

The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
log shown in the “NISSAN Service and Mainte-

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.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces

“NISSAN Service and Maintenance Guide” for
change intervals.
To replace the filter, perform the following proce-
dure: 1. Open the glove box and press in on the

CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a washer
solution or a mild detergent. Your windshield is
clean if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
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.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.

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.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”.
Two types of fuses are used. Type
Ais used in
the fuse boxes in the engine compartment. Type
