If you have a flat tire, see “Flat tire” (P.6-
3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears on the vehi-
cle information display, one or more of
your tires is significantly under-inflated.
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 more details, see “Low tire pressure
warning light” (P.2-13), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-3) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-
ways prior to long distance trips.
The recommended tire pressure
specifications are shown on the
Tire and Loading Information label
under the “Cold Tire Pressure”
heading. The Tire and Loading In-
formation label is affixed to the
driver side center pillar. Tire pres-
sures should be checked regularly
because:
.Most tires naturally lose air over
time.
. Tires can lose air suddenly when
driven over potholes or other
objects 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 after
the vehicle has been parked for 3 or
more hours, or driven less than 1
mile (1.6 km) at moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely affect tire life and vehicle hand-
ling.
WARNING
.
Improperly inflated tires can
fail suddenly and cause an
accident.
. The Gross Vehicle Weight
rating (GVWR) is located on
the F.M.V.S.S./C.M.V.S.S. la-
bel. The vehicle weight ca-
pacity is indicated on the
Tire and Loading Informa-
tion label. Do not load your
vehicle beyond this capacity.
Overloading your vehicle
may result in reduced tire
life, unsafe operating condi-
tions due to premature tire
failure, or unfavorable hand-
ling characteristics and
could also lead to a serious
accident. Loading beyond
the specified capacity may
also result in failure of other
vehicle components.

SDI1575
Example
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 identify
the tire in case of a recall.
SDI1606
Example
Tire size (example:
P215/60R16 94H)
1. P: The “P” indicates the tire isdesigned for passenger vehicles.
(Not all tires have this informa-
tion.)
2. Three-digit number (215): This number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3. Two-digit number (60): This number, known as the aspect
ratio, gives the tire’s ratio of height to width.
4. R: The “R” stands for radial.
5. Two-digit number (16): This number is the wheel or rim
diameter in inches.
6. Two- or three-digit number (94): This number is the tire’s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because
it is not required by law.
7. H: Tire speed rating. You should not drive the vehicle faster than
the tire speed rating.

8-32Do-it-yourself
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 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-
Do-it-yourself8-33

portant Tire Safety Informa-
tion” (US) or “Tire Safety In-
formation” (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. .
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
Do-it-yourself8-35

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
Maintenance and schedules9-3

9-4Maintenance and schedules
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are
operating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate
properly and that the wipers do not
streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example,
each time you check the engine oil or
refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level. NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1.
Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake and clutch fluid levels*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im- mediately have the exhaust system in-
spected. It is recommended you visit a
NISSAN dealer for this service. (See “Pre-
cautions when starting and driving” (P.5-
2) for exhaust gas (carbon monoxide).)
Fluid leaks:
Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks
or if gasoline fumes are evident, check for
the cause and have it corrected immedi-
ately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control
dust. It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt
