be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed. For additional information re-
garding brake inspections, see the appro-
priate maintenance schedule information

WARNING
Do not touch bulb by hand while it is lit
or right af ter being turned off. Burning
may result.
CAUTION
• Do not touch glass surface of the bulb
with bare hands or allow oil or grease to
get on it to prevent damage to bulb.
• Do not leave the bulb out of the lamp
reflector for a long time because dust,
moisture, smoke, etc. may affect the
performance of the lamp.
• Fog may temporarily form inside the
lens of the exterior lights in the rain or
in a car wash. A temperature difference
between the inside and the outside of
the lens causes the fog. This is not a
malfunction. If large drops of water col-
lect inside the lens, it is recommended
that you visit a NISSAN dealer for
servicing.

If you have a flat tire, see “Flat tire”
(P. 6-3).
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
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
warning is displayed in the odom-
eter, or the “Tire Pressure Low — Add
Air” appears in the vehicle informa- tion 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 additional information, see “Low
tire pressure warning light” (P. 2-13),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5), and “Flat tire” (P. 6-3).
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.

WARNING
• Tires should be periodically in-
spected 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
the 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 technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• 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.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” (P. 10-10).
WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, Vehicle Dy-
namic Control (VDC) system, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects
may lead to accidents and could re-
sult in serious personal injury.
• If your vehicle was originally
equipped with four tires that were
the same size and you are only re-
placing two of the four 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
conditions and cause an accident
and personal injury.
Do-it-yourself8-39

•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,
see “Wheels and tires” (P. 10-10).
• When using 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.
