name is shown.
Other tire-related terminology:
In addition to the many terms that
are defined throughout this sec-
tion, 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
particular side that must always
face outward when mounted on a
vehicle.
TYPES OF TIRES
WARNING
.
When changing or replacing tires,
be sure all four tires are of the
same type (Example: Summer, All
Season or Snow) and construc-
tion. A NISSAN dealer may be able
to help you with information
about tire type, size, speed rating
and availability.

.Replacement tires may have a
lower speed rating than the fac-
tory 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
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) 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 con-
ditions. All Season tires are identified by
ALL SEASON and/or M&S (Mud and Snow)
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 reduced in snow and ice.
Summer tires do not have the tire trac-
tion rating M&S on the tire sidewall.
If you plan to operate your vehicle in
snowy or icy conditions, NISSAN recom-
mends 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 original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower
speed ratings than factory equipped tires
and may not match the potential max-
imum vehicle speed. Never exceed the
maximum speed rating of the tire.
If you install snow tires, they must be the
same brand, construction and tread pat-
tern on all four wheels, and the same
sizes as the original tires.
For additional traction on icy roads,
studded 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 sur-
faces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be
installed on 19-inch size tires. Doing
so will cause damage to the vehicle.
If you plan to use tire chains/cables,
you should install 18-inch size tires
on your vehicle.
Use of tire chains may be prohibited
according 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 manufacturer’s suggestions.
Use only SAE Class S chains. Class “S”
chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed
to meet the SAE standard minimum
clearances between the tire and the
closest vehicle suspension or body com-
ponent required to accommodate the
Do-it-yourself8-33

8-34Do-it-yourself
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when re-
commended by the tire chain manufac-
turer 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 load-
ing your vehicle when using tire chains. In
addition, drive at a reduced speed. Other-
wise, 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.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.
Do not use tire chains on dry roads.
Driving with tire chains in such conditions
can cause damage to the various me-
chanisms of the vehicle due to some
overstress.CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this
vehicle because the front tires are
a different size than the rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being
installed in place of the front
wheels. The spare tire can be
installed in place of the front and
rear wheels. When installing the
spare tire in the front wheel, the
hole in the spare tire wheel must be
aligned with the pin on the brake
rotor.
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.).
. For additional information
regarding tires, refer to “Im-
portant Tire Safety Informa- tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.

SDI1663
Wear indicator
Wear indicator location
marks. The locations are
shown by “
”, “TWI”, etc.
depending on tire types.
Tire wear and damage
WARNING
. Tires should be periodically
inspected 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 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 tech-
nician, because some tire
damage may not be ob-
vious. Replace the tires as
necessary to prevent tire
failure and possible perso-
nal injury.
. Improper service of the
spare tire may result in ser-
ious personal injury. If it is
necessary to repair the
spare tire, it is recom-
mended you visit a NISSAN
dealer for this service.
. For additional information
regarding tires, refer to “Im- portant Tire Safety Informa-
tion” (US) or “Tire Safety
Information” (Canada) in the
Warranty Information Book-
let.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load
carrying capacity as originally equipped.
(See “Specifications” (P.10-9) for recom-
mended types and sizes of tires and
wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use
of tires of different brands, con-
struction (bias, bias-belted or ra-
dial), or tread patterns can
adversely affect the ride, braking,
handling, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibra-
tion, headlight aim and bumper
height. Some of these effects
may lead to accidents and could
result in serious personal injury.
Do-it-yourself8-35

8-36Do-it-yourself
.If your vehicle was originally
equipped with 4 tires that were
the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-10) of this manual for
wheel off-set dimensions.
. Since the spare tire is not
equipped with the TPMS, when a
spare tire is mounted or a wheel
is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 1 minute. The light
will remain on after 1 minute. Have your tires replaced and/or
TPMS system reset as soon as
possible. It is recommended you
visit a NISSAN dealer for these
services.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. 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 deformed 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 tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) 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 vehi-
cle could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the NISSAN Warranty Infor-
mation Booklet.

Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) (if so equipped)
Observe the following precautions if the
T-type spare tire must be used, otherwise
your vehicle could be damaged or in-
volved in an accident.
WARNING
.The T-type spare tire should be
used for emergency use. It should
be replaced with the standard tire
at the first opportunity to avoid
possible tire or differential da-
mage.
. Drive carefully while the TEMPOR-
ARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
. Periodically check spare tire in-
flation pressure. Always keep the
pressure of the TEMPORARY USE
ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the
pressure of the full size spare tire
(if so equipped) at the recom-
mended pressure for standard tires, as indicated on the Tire
and Loading Information label.
For Tire and Loading Information
label location, see “Tire and Load-
ing Information label” in the index
of this manual.
. With the TEMPORARY USE ONLY
spare tire installed do not drive
your 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 front wheels and
original tire used on the rear
wheels (drive wheels). Use tire
chains only on the two rear origi-
nal tires.
. 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.
CAUTION
.Do not use tire chains on a
TEMPORARY 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 automatic car
wash since it may get caught.
EMERGENCY TIRE PUNCTURE RE-
PAIR KIT (if so equipped)
The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can
be used to temporarily repair minor tire
punctures.
If possible, have the vehicle towed to a
facility that can repair or replace the flat
tire. Using the emergency tire puncture
repair kit may cause a malfunction of the
tire pressure sensor and cause the low
tire pressure warning light to illuminate.
See “Flat tire” (P.6-3) for more details.

9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in 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 per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the 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 responsibility to perform these pro-
cedures 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
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is re-
commended you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through tech-
nical bulletins, service tips and training
programs. They are completely qualified
to work on NISSAN vehiclesbeforework
begins.
You can be confident that a NISSAN
dealer’s service department can perform
the service needed to meet the mainte-
nance requirements on your vehicle. During the normal day-to-day operation
of the vehicle, general maintenance
should be performed regularly as pre-
scribed in this section. If you detect any
unusual sounds, vibrations or smells, be
sure to check for the cause, or it is
recommended to have a NISSAN dealer
do it promptly. In addition, it is recom-
mended you visit a NISSAN dealer if you
think that repairs are required.
When performing any checks or mainte-
nance work, closely observe “Mainte-
nance precautions” (P.8-2) of this manual.
EXPLANATION OF GENERAL MAIN-
TENANCE ITEMS
Additional information on the following
items with “*” is found in the “8. Do-it-
yourself” section of this manual.
Outside the vehicle
The maintenance items listed here should
be performed from time to time, unless
otherwise specified.
Doors and engine hood:
Check that all
doors and the engine hood, operate
properly. Also ensure that all latches lock
securely. Lubricate hinges, latches, latch
pins, rollers and links if necessary. Make
sure that the secondary latch keeps the
hood from opening when the primary
latch is released.
MAINTENANCE REQUIREMENT GENERAL MAINTENANCE

When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When
checking the tires, make sure no wheel
nuts are missing, and check for any loose
wheel nuts. Tighten if necessary.
Tire rotation*: Tires cannot be rotated, as
the front tires are a different size from the
rear tires and the direction of wheel
rotation is fixed in each tire.
Tires*: Check the pressure with a gauge
often 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.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve
core and cap when the tires are replaced
due to wear or age.
Wheel alignment and balance: If the
vehicle should pull to either side while
driving on a straight and level road, or if you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the NISSAN Warranty Infor-
mation Booklet.
Windshield:
Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe
properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled mainte-
nance, cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) me-
chanism: On a fairly steep hill, check that your vehicle is held securely with the shift
lever in the P (Park) position without
applying any brakes.
Brake pedal:
Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, have your vehicle checked
immediately. It is recommended you visit
a NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with
only the parking brake applied. If the
parking brake needs adjusted, it is re-
commended you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
