WARNING
∙ Operating the engine with the air
cleaner filter off can cause you or oth-
ers to be burned. The air cleaner filter
not only cleans the intake air, it also
stops the flame if the engine back-
fires. If the air cleaner is not installed
and the engine backfires, you could be
burned. Never drive with the air
cleaner filter off. Be cautious working
on the engine when the air cleaner is
off.∙ 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,
release the retaining clips
A, then release
the holders at the back of the unit. Pull the
unit upward
B.
The viscous paper type filter element (if so
equipped) should not be cleaned and re-
used. The dry paper type filter element (if so
equipped) may be cleaned and reused. Re-
place the air filter according to the mainte-
nance log shown in a separate mainte-
nance booklet.
When replacing the air filter, wipe the inside
of the air cleaner housing and the cover
with a damp cloth.

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer’s suggestions.Use only SAE class “S”
chains.Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tires.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chainmust be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when using
tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

Some day-to-day and regular mainte-
nance is essential to maintain your vehicle
good mechanical condition, as well as its
emissions and engine performance.
It is the owner’s responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
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 re-
sponsibility to perform these procedures
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

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.
The fluid should be at the bottom of the
filler opening. Vehicles operated in high
temperatures or under severe conditions
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 conditions
such as:
1.Installation or extended use of elec-
tronic accessories that consume bat-
tery 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 and clutch (if so equipped) fluid
level*:Make sure that the brake and clutchfluid levels are between the MIN and MAX
lines on the reservoir.
Engine coolant level*:Check the coolant
level when the engine is cold.
Engine drive belts*:Make sure the drive

and have it corrected immediately.
9-4Maintenance and schedules

5.Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed the
available cargo and luggage load
capacity calculated in step 4.
Before driving a loaded vehicle, con-
firm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. For addi-
tional information, refer to “Measure-
ment of weights” in this section.
Also check tires for proper inflation
pressures. For additional informa-
tion, refer to “Tire and Loading Infor-
mation label” in this section.
LOADING TIPS
∙ The GVW must not exceed GVWR
or GAWR as specified on the F.M-
.V.S.S. certification label.
∙ Do not load the front and rear
axle to the GAWR. Doing so will
exceed the GVWR.
WARNING
∙ Properly secure all cargo with
ropes or straps to help prevent
it from sliding or shif ting. Do not
place cargo higher than the
seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
∙ Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your
vehicle can break, tire damage
could occur, or it can change the
way your vehicle handles. This
could result in loss of control
and cause personal injury.
∙
Overloading and improper load-
ing not only can shorten the life
of your vehicle and the tire, but
can also cause unsafe vehicle
handling and longer braking dis-
tances. This may cause a prema-
ture tire failure which could re-
sult in a serious accident and
personal injury. Failures caused
by overloading are not covered
by the vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the ve-
hicle is loaded, drive to a scale and
weigh the front and the rear wheels
separately to determine axle loads.
Individual axle loads should not ex-
ceed either of the Gross Axle Weight
Ratings (GAWR). The total of the axle
loads should not exceed the Gross
Vehicle Weight Rating (GVWR). These
ratings are given on the vehicle cer-
tification label. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
