TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
This vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit and warning is displayed in the odom-
eter, or the “Tire Pressure Low — Add Air”
appears in the vehicle information display,
one or more of your tires is significantly
under-inflated.
The TPMS will activate only when the ve-
hicle 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, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “Starting and
driving” section, and “Flat tire” in the “In case
of emergency” section of this manual.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./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The Tire
and Loading Information label is af-
fixed to the driver side center pillar.
Tire pressures should be checked
regularly 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 (if
so equipped) provides visual and au-
dible signals outside the vehicle for
inflating tires to the recommended
COLD tire pressure. For additional in-
formation, refer to “TPMS with Easy-
Fill Tire Alert” in the “Starting and driv-
ing” section of this manual.
Incorrect tire pressure, including
under inflation, may adversely af-
fect 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./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label.
Do not load your vehicle be-
yond this capacity. Overload-
ing your vehicle may result in
reduced tire life, unsafe operat-
ing conditions due to prema-
ture tire failure, or unfavorable
handling characteristics and
could also lead to a serious ac-
cident. Loading beyond the
specified capacity may also re-
sult 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 Informa-
tion” (Canada) in the Warranty
Information Booklet.

1Seating capacity: The maximum num-
ber of occupants that can be seated in
the vehicle.
2Original tire size: The size of the tires
originally installed on the vehicle at the
factory.
3Cold tire pressure: Inflate the tires to
this pressure when the tires are cold.
Tires are considered COLD af ter the ve-
hicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km)
at moderate speeds. The recom- mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the ve-
hicle's GVWR.

section.
5Spare tire size.
6Vehicle load limit: Refer to “Vehicle load-
ing information” in the “Technical and
consumer information” section of this
manual.
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing sound of air escap-
ing from the tire is heard while checking
the pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge.

4. Read the tire pressure on the gaugestem and compare to the specification
shown on the Tire and Loading Informa-
tion label.
5. Add air to the tire as needed. If too much air is added, press the core of the valve
stem briefly with the tip of the gauge
stem to release pressure. Recheck the
pressure and add or release air as
needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, in- cluding the spare.Grades: S, SV, SR

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized infor-
mation on the sidewall of all tires.
This information identifies and de-
scribes the fundamental character-
istics of the tire and also provides the
Tire Identification Number (TIN) for
safety standard certification. The TIN
can be used to identif y the tire in
case of a recall.
WDI0394
Example
Do-it-yourself8-31

O2TIN (Tire Identification Number)
for a new tire (example: DOT XX XX
XXX XXXX)
1. DOT: Abbreviation for the “Depart- ment Of Transportation”. The
symbol can be placed above, be-
low or to the lef t or right of the Tire
Identification Number.
2. Two-digit code: Manufacturer's identification mark. 3. Two-digit code: Tire size.
4. Three-digit code: Tire type code
(Optional).
5. Four numbers represent the week and year the tire was built.
For example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing then
look on the other sidewall of the
tire.
O3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester and oth-
ers.
O4Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure.
O5Maximum load rating
This number indicates the maxi-
mum load in kilograms and pounds
that can be carried by the tire. When
replacing the tires on the vehicle, al-
ways use a tire that has the same
load rating as the factory installed
tire.
LDI2786
Example
Do-it-yourself8-33

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
Manufacturer or brand name is
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 to malfunction resulting in per-
sonal injury or death, excessive tire
wear and may damage the transmis-
sion 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 the tires ev-
ery 7,500 miles (12,000 km).
For additional information on tire replacing
procedures, refer to “Flat tire” in the “In case
of emergency” section of this manual.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.Wheel nut tightening torque:
83 f t-lb (113 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 inter-
val.
WARNING
• Af ter rotating the tires, check and ad-
just the tire pressure.
• 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 regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Tire wear and damage

2. Location mark
WDI0258WDI0259
8-36Do-it-yourself

•If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad/shoe wear. For additional infor-
mation on wheel-off set dimensions,
refer to “Wheels and tires” in the
“Technical and consumer informa-
tion” section of this manual.
• When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS. •
The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. Con-
tact a NISSAN dealer for ID
registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.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.
8-38Do-it-yourself

Spare tire (TEMPORARY USE ONLY
spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
WARNING
• The spare tire should be used for
emergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
• Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
• Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY spare
tire at 420 kPa, 4.2 bar (60 psi).
• With the TEMPORARY USE ONLY spare
tire installed do not drive the vehicle
at speeds faster than 50 mph (80
km/h). •
When 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).
• Tire 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.
• Do not use the spare tire on other
vehicles.
• Do not use more than one spare tire
at the same time.
• Do not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
• Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
• Because 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 auto-
matic car wash since it may get
caught.
