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.

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

9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital
link in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those
items which should be checked during
normal day-to-day operation. They are
essential for proper vehicle operation. It is
your responsibility to perform these pro-
cedures regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and
only a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is re-
commended you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through tech-
nical bulletins, service tips and training
programs. They are completely qualified
to work on NISSAN vehiclesbeforework
begins.
If your vehicle is involved in a collision, it is
recommended that you ask your NISSAN
dealer where the nearest NISSAN Certified
Collision Center is located, or go to http://
collision.nissanusa.com.
You can be confident that a NISSAN
dealer’s service department can perform
the service needed to meet the mainte-
nance requirements on your vehicle. During the normal day-to-day operation
of the vehicle, general maintenance
should be performed regularly as pre-
scribed in this section. If you detect any
unusual sounds, vibrations or smells, be
sure to check for the cause and have it
checked promptly. In addition, it is re-
commended you visit a NISSAN dealer if
you think that repairs are required.
When performing any checks or mainte-
nance work, closely observe “Mainte-
nance precautions” (P.8-2) of this manual.

streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example,
each time you check the engine oil or
refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. 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.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in- spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
4) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
may accumulate. For additional informa-

tion, see “Cleaning exterior” (P.7-2).
Windshield washer fluid*:Check that
there is adequate fluid in the reservoir.The following descriptions are provided
to give you a better understanding of the
scheduled maintenance items that
should be regularly checked or replaced.
The maintenance schedule indicates at
which mileage/time intervals each item
requires service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day op-
eration. Refer to “General maintenance”
(P.9-2).
Items marked with “*” are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform main-
tenance on these items in order to

NOTE:
NISSAN does not advocate the use of
non-OEM approved aftermarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the aftermar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by
NISSAN. For recommended fuel, lubricants,
fluids, grease, and refrigerant, refer to
“Capacities and recommended fluids/
lubricants” (P.10-2) of this manual.
