REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped spark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the “Maintenance and sched-
ules” section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
•Always replace spark plugs with rec-
ommended or equivalent ones.

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

Information label under the “Cold
Tire Pressure” heading. The Tire and
Loading Information label is affixed
to the driver side center pillar. Tire
pressures should be checked regu-
larly because:
• Most tires naturally lose air overtime.
• Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert
provides visual and audible signals
outside the vehicle for inflating tires
to the recommended COLD tire pressure. For additional information,
see “TPMS with Easy-Fill Tire Alert”
(P. 5-8).
Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
•
Improperly inflated tires can
fail suddenly and cause an
accident.
•The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S. certification label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capac-
ity. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure, or
unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading be- yond the specified capacity
may also result in failure of
other vehicle components.
•Before 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.
•For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

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 tire
size. 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 chain must 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
rear wheels and not on the front wheels.
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.
Use only the 2WD range when driving on
clear paved roads.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating tires
every 7,500 miles (12,000 km).
For additional information on tire
replacing procedures, see “Flat tire”
(P. 6-3).
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.Wheel nut tightening torque:
Non-XD models:
98 f t-lb (133 N·m)
XD models: 131 f t-lb (177 N·m)
The wheel nuts must be kept tight-
ened to specifications at all times.
It is recommended that wheel nuts
be tightened to specification at
each tire rotation interval.
WARNING
• Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
• Do not include the spare tire in
the tire rotation. •
For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
• Af ter rotating the tires, do not
use the Easy-Fill Tire Alert to
adjust the tire pressure. In-
stead use a gauge to adjust the
tires to the correct pressure in
accordance with Tire and Load-
ing Information label.
CAUTION
To ensure proper operation of the
Easy-Fill Tire Alert system af ter a
tire rotation, re-set and register
the sensor to their new installed
locations. It is recommended that
you visit a NISSAN dealer for this
service.

Do-it-yourself8-43
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required. Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
•
For 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
• Wash the wheels when washing the ve- hicle to maintain their appearance.
• Clean the inner side of the wheels when the wheel is changed or the underside of
the vehicle is washed.
• Do not use abrasive cleaners when washing the wheels.
• Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
• NISSAN recommends waxing the road wheels to protect against road salt in ar-
eas where it is used during winter.
Spare tire (FULL SIZE TEMPORARY
USE ONLY spare tire)
When using a wheel without the TPMS such
as the spare tire, the TPMS will not function.
Your vehicle may be equipped with a full
size spare that is a different size or brand
than the tires originally installed on the ve-
hicle. This full size spare tire is intended for
temporary use only and should be re-
placed at the first opportunity.
Observe the following precautions if the
FULL SIZE TEMPORARY USE ONLY spare tire
must be used. Otherwise, your vehicle
could be damaged or involved in an
accident:
WARNING
To help reduce the risk of a crash which
may result in personal injury or death:
• The TEMPORARY FULL SIZE spare tire
should be used for emergency use
only. It should be replaced with the
standard tire at the first opportunity
to avoid possible tire or differential
damage.
