. Use Genuine NISSAN PSF or
equivalent. For further brake fluid specification infor-
mation, see “Capacities and recom-
mended fluids/lubricants” (P.10-2).
WARNING
.
Use only new fluid from a sealed
container. Old, inferior or con-
taminated fluid may damage the
brake system. The use of impro-
per fluids can damage the brake
system and affect the vehicle’s
stopping ability.
. Be sure to clean the filler cap
before removing.
. Brake fluid is poisonous and
should be stored carefully in
marked containers out of the
reach of children.
CAUTION
.Do not add brake fluid with the
ignition switch in the ON position
or the engine running. Doing so
could make the brake fluid over-
fill when the ignition switch is
turned off. .
Do not spill the fluid on painted
surfaces. This will damage the
paint. If fluid is spilled, wash the
surface with water.

BRAKE FLUID

Add a washer solvent to the washer for
better cleaning. In the winter season, add
a windshield washer antifreeze. Follow
the manufacturer’s instructions for the
mixture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of window washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner
& Antifreeze or equivalent.
CAUTION
.Do not substitute engine anti-
freeze coolant for window
washer solution. This may result
in damage to the paint.
. Do 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 reservoir tank.
. Pre-mix washer fluid concen-
trates with water to the manu-
facturer’s recommended levels
before pouring the fluid into the
window washer reservoir tank. Do not use the window washer re-
servoir tank to mix the washer
fluid concentrate and water.
.
Keep the battery surface clean and
dry. Clean the battery with a solution
of baking soda and water.
. Make certain the terminal connec-
tions are clean and securely tightened.
. If the vehicle is not to be used for 30
days or longer, disconnect the nega-
tive (−) battery terminal cable to pre-
vent discharging it.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1. Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
WARNING
. Do not expose the battery to
flames or electrical sparks. Hy-
drogen gas generated by the
battery is explosive. Do not allow
battery fluid to contact your skin,

BATTERY

JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-12). If the engine does not
start by jump starting, the battery may
have to be replaced. It is recommended
you visit a NISSAN dealer for this service.CAUTION
.Do not ground accessories di-
rectly to the battery terminal.
Doing so will bypass the variable
voltage control system and the
vehicle battery may not charge
completely.
. Use electrical accessories with
the engine running to avoid dis-
charging the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

cing drive belts. The engine could
rotate unexpectedly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or loosen-
ess. If the belt is in poor condition or

REPLACING SPARK PLUGS
If replacement is required, it is recom-
mended you visit a NISSAN dealer for this
service.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section, but do
not reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
SPARK PLUGS

SDI2515
To remove the filter, release the lock pinsand pull the unit upward.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance schedule shown in the “9.
Maintenance and schedules” section.
When replacing the filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.
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 flame if the engine back-
fires. If it isn’t there, and the
engine 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 re-
moved. Doing so could result in
serious injury.

AIR CLEANER

It is recommended you visit a NISSAN
dealer if checking or replacement is
required.If the brakes do not operate properly,
have the brakes checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every
time the brake pedal is applied.
WARNING
Have your brake system checked if
the brake pedal height does not
return to normal. It is recommended
you visit a NISSAN dealer for this
service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first
occur only when the brake pedal is
depressed. After more wear of the brake
pad, the sound will always be heard even
if the brake pedal is not depressed. Have
the brakes checked as soon as possible if
the wear warning 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
normal and does not affect the function
or performance of the brake system.
Proper brake inspection intervals
should be followed.
For additional infor-
mation, see the maintenance schedule
shown in the “9. Maintenance and sche-
dules” section.
BRAKE BOOSTER
Check the brake booster function as
follows:
1. With the engine off, depress and release the foot brake pedal more
than 20 times. When the foot brake
pedal movement (distance of travel)
remains the same from one pedal
application to the next, continue on
to the next step.
2. While depressing the foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal de-
pressed for about 30 seconds.
4. Run the engine for 1 minute without depressing the foot brake pedal, then
turn it off. Depress the foot brake
pedal several times. The pedal travel
distance will decrease gradually with
