Your new NISSAN has been designed to have
minimum maintenance requirements with longer
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your NIS-
SAN’s 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 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 mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide.” You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration of the vehicle. They are essential if your
vehicle is to continue to operate properly. It is
your responsibility to perform these maintenance
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 you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hiclesbeforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economic way.During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Tires*Check the pressure with a gauge at least
once a month and always prior to long distance
trips. If necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.

COLD. Tires are considered COLD after the
vehicle has been parked for three or more hours,
or driven less than 1 mile (1.6 km) at moderate
speeds. COLD tire pressures are shown on the
tire placard affixed to the driver’s side rear door
pillar.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident.
cThe vehicle weight capacity is indicated
on the F.M.V.S.S. certification label. Do
not load your vehicle beyond this ca-
pacity. Overloading your vehicle may
result in reduced tire life, unsafe oper-
ating conditions due to premature tire
failure, or unfavorable handling charac-
teristics and could also lead to a seri-
ous accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
cBefore taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.cDo not drive your vehicle over 85 MPH
(137 km/h) unless it is equipped with
high speed rated tires. Driving faster
than 85 MPH (137 km/h) may result in
tire failure, loss of control and possible
injury.
cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.
TYPES OF TIRES
WARNING
cWhen changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. A NISSAN dealer may be
able to help you with information about
tire type, size, speed rating and avail-
ability. Replacement tires may have a
lower speed rating than the factory
equipped tires, and may not match the
potential maximum vehicle speed.
Never exceed the maximum speed rat-
ing of the tire.cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.
All season tires
NISSAN specifies All Season tires on some mod-
els to provide good performance all year, includ-
ing snowy and icy road conditions. All Season
tires are identified by ALL SEASON and/or M&S
on the tire sidewall. Snow tires have better snow
traction than All Season tires and may be more
appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced 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 rating to the

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires every
7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emergency”
section of this manual for tire replacing proce-
dures.
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
80 ft-lb (108 N·m)The wheel nuts must be kept tightened to
specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation interval.
WARNING
cAfter rotating the tires, check and ad-
just the tire pressure.
cRetighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
cDo not include the spare tire in the tire
rotation.
cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.

Care of wheels
cWash the wheels when washing the vehicle to
maintain their appearance.
cClean the inner side of the wheels when the
wheel is changed or the underside of the ve-
hicle is washed.
cDo not use abrasive cleaners when washing
the wheels.
cInspect wheel rims regularly for dents or cor-
rosion. Such damage may cause loss of pres-
sure or poor seal at the tire bead.
cNISSAN recommends waxing the road wheels
to protect against road salt in areas where it is
used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used.
Otherwise, your vehicle could be damaged or
involved in an accident:
WARNING
cThe spare tire should be used for emer-
gency use only. It should be replaced
with the standard tire at the first oppor-
tunity to avoid possible tire or differen-
tial damage.
cDrive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
cPeriodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 60 psi (420 kPa, 4.2 bar) .
cWith the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle at
speeds faster than 50 MPH (80 km/h) .
cWhen driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
rear wheels and the original tire used
on the front wheels (drive wheels) . Use
tire chains only on the front (original)
tires.cTire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate
than the standard tire. Replace the
spare tire as soon as the tread wear
indicators appear.
cDo not use the spare tire on other
vehicles.
cDo not use more than one spare tire at
the same time.
cDo not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
cDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause dam-
age to the vehicle.
cBecause the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.
