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. .
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.

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

and signs of leaking. Replace any deterio-
rated or damaged parts immediately.
Brake pads and rotors:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or da-
maged parts immediately.Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deteriora-
tion, and damage. Tighten connections or
replace parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driv-
ing for prolonged periods in dusty condi-
tions, replace the filter more frequently.
Steering gear and linkage, axle and
suspension parts:
Check for damage, looseness, and leak-
age of oil or grease. Under severe driving
conditions, inspect more frequently.
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.
Transmission fluid/oil, differential oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and eco-
nomical driving, NISSAN provides two
maintenance schedules that may be
used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals,
up to 120,000 miles (192,000 km)/144
months. For most people, the odometer
reading will indicate when service is
needed. However, if you drive very little,
your vehicle should be serviced at the
regular time intervals shown in the sche-
dule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING CONDI-
TIONS
Additional maintenance items for se-
vere operating conditions;
should be
performed on vehicles that are driven
under especially demanding conditions.
Additional maintenance items should be
performed if you primarily operate your
vehicle under the following conditions:
. Repeated short trips of less than 5
miles (8 km).
. Repeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.

the Gross Vehicle Weight Rating
(GVWR) or the Gross Axle Weight
Rating (GAWR) for your vehicle. (See
“Measurement of weights” (P.10-21).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS
.The GVW must not exceed GVWR
or GAWR as specified on the F.M.
V.S.S./C.M.V.S.S. certification la-
bel.
. Do not load the front and rear
axle to the GAWR. Doing so will
exceed the GVWR.
WARNING
.Properly secure all cargo to
help prevent it from sliding
or shifting. Do not place
cargo higher than the seat-
backs. In a sudden stop or
collision, unsecured cargo
could cause personal injury. .
Do not load your vehicle any
heavier than the GVWR or
the maximum front and rear
GAWRs. If you do, parts of
your vehicle can break, tire
damage could occur, or it
can change the way your
vehicle handles. This could
result in loss of control and
cause personal injury.
. Overloading could not only
shorten the life of your ve-
hicle and the tires, but also
could lead to hazardous ve-
hicle handling and long
braking distance. This may
cause a premature tire mal-
function, which could result
in a serious accident and
personal injury. Failures
caused by overloading are
not covered by the vehicle’s
warranty. MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shifts that could affect the
balance of your vehicle. When the
vehicle is loaded, drive to a scale
and weigh the front and the rear
wheels separately to determine
axle loads. Individual axle loads
should not exceed either of the
gross axle weight ratings (GAWR).
The total of the axle loads should
not exceed the gross vehicle
weight rating (GVWR). These ratings
are given on the vehicle certifica-
tion label. If weight ratings are
exceeded, move or remove items
to bring all weights below the
ratings.

DOT (Department Of Transportation)
Quality Grades: All passenger car tires
must conform to federal safety require-
ments in addition to these grades.
Quality grades can be found where ap-
plicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Tempera-
ture A
TREADWEAR
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half (1 1/2) times as
well on the government course as a tire
graded 100. The relative performance of
tires depends upon actual conditions of
their use, however, and may depart sig-
nificantly from the norm due to variations
in driving habits, service practices and
differences in road characteristics and
climate.
TRACTION AA, A, B AND C
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering, hy-
droplaning, or peak traction charac-
teristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire life,
and excessive temperature can lead to
sudden tire failure. The grade C corre-
sponds to a level of performance whichall passenger car tires must meet under
the Federal Motor Vehicle Safety Stan-
dard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Exces-
sive speed, under-inflation, or exces-
sive loading, either separately or in
combination, can cause heat build-
up and possible tire failure.
