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
intervals, see “Maintenance schedules"

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all four
tires except the spare. When the low
tire pressure warning light is lit and
the “Tire Pressure Low - Add Air”
warning appears in the vehicle infor-
mation display, one or more of your
tires is significantly under-inflated. If equipped, the system also displays
pressure of all tires (except the spare
tire) on the display screen by send-
ing a signal from a sensor that is
installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, see
“Warning lights, indicator lights and
audible reminders” (P. 2-13), “Tire
Pressure Monitoring System (TPMS)”
(P. 5-5), and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S. certifica-
tion label or the Tire and Loading
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 over
time.
• 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
WHEELS AND TIRES

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.

O6Term of “tubeless” or “tube type”
Indicates whether the tire requires
an inner tube (“tube type”) or not
(“tubeless”).
O7The word “radial”
The word “radial” is shown if the tire
has radial structure.
O8Manufacturer or brand name

shown.
Other Tire-related Terminology
In addition to the many terms that
are defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or
deeper than the same molding on
the other sidewall of the tire, or (2)
the outward facing sidewall of an
asymmetrical tire that has a particu- lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES
WARNING
• When 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 infor-
mation about tire type, size, speed
rating and availability.
• 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 rating of the tire.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the low
tire pressure warning system. •
Always use tires of the same type,
size, brand, construction 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 can cause the
Vehicle Dynamic Control (VDC) sys-
tem and 4WD system to malfunction
resulting in personal injury or death,
excessive tire wear and may damage
the transmission and differential
gears.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. 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 appropri-
ate in some areas.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating tires
every 7,500 miles (12,000 km).
For additional information on tire re-
placing 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.

2. Location mark
WARNING
• Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in
the tread. If excessive wear,
cracks, bulging or deep cuts
are found, the tire(s) should be
replaced.
• The original tires have built-in
tread wear indicators. When
the wear indicators are visible,
the tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, including the
spare, over 6 years old checked
by a qualified technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
