faces. This will damage the paint. If fluid
is spilled, immediately wash the sur-
face with water.

WARNING
• Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn't
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful 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.
To remove the filter from the air cleaner,
push the tabs and pull the cover upward.
The viscous paper type filter element
should not be cleaned and reused. Replace
the air filter according to the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.NOTE:
Af ter installing a new air cleaner filter,
make sure the air cleaner cover is seated
in the housing and latch the tabs.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information on change
intervals, see “Maintenance schedules"
(P. 9-7).
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for

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 on
the appropriate maintenance schedule re-
garding brake inspections, see "Mainte-
nance schedules" (P. 9-7).LDI2710

HEADLIGHTS
For additional information on headlight
bulb replacement, refer to the instructions
outlined in this section.
Replacing the halogen headlight
bulb (if so equipped)
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. Because the headlight assembly
must be removed from the vehicle for bulb
replacement, it is recommended that you
visit a NISSAN dealer for this service.
CAUTION
• Aiming is not necessary af ter replac-
ing the bulb. When aiming adjust-
ment is necessary, it is recom-
mended that you visit a NISSAN
dealer for this service.
• Do not leave the headlight assembly
open without a bulb installed for a
long period of time. Dust, moisture,
smoke, etc. entering the headlight
body may affect bulb performance.
Remove the bulb from the headlight
assembly just before a replacement
bulb is installed. •
Only touch the base when handling
the bulb. Never touch the glass enve-
lope. Touching the glass could sig-
nificantly affect bulb life and/or
headlight performance.
• High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
• Use the same number and wattage
as shown in the chart.
Fog may temporarily form inside the lens
of the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
it is recommended that you visit a NISSAN
dealer for servicing.
Replacing the LED headlight bulb
(if so equipped)
If LED headlight bulb replacement is re-
quired, it is recommended that you visit a
