8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to P (Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-40).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and

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 “Tire Pressure
Low Add Air” warning appears in the
vehicle 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.2-15), “Tire Pressure Mon-
itoring System (TPMS)” (P.5-5) 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.

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.

.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 size, brand, construction and tread
pattern on all four wheels.
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
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
Do-it-yourself8-35

8-36Do-it-yourself
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 the full-size
temporary use only spare tire (if so
equipped).
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.
SDI1662
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 7,500 miles (12,000 km).
(See “Flat tire” (P.6-3) for tire repla-
cing procedures.)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.Wheel nut tightening torque:98 ft-lb (133 N·m)
The wheel nuts must be kept
tightened to the specification at all times. It is recommended that
wheel nuts be tightened to the
specification at each tire rotation
interval.
WARNING
.
After rotating the tires,
check and adjust 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 full-size
temporary use only spare
tire (if so equipped) in the
tire rotation.
. 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.

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.10-8) 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.
. For Two-Wheel Drive (2WD) mod-
els, if your vehicle was originally
equipped with 4 tires that were
Do-it-yourself8-37

8-38Do-it-yourself
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.10-9) 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 damaged or
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.
Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias,
bias-belted or radial), and tread
pattern on all four wheels. Failure
to do so may result in a circum-
ference difference between tires
on the front and rear axles which
will cause excessive tire wear and
may damage the transmission,
transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
