Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
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.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should con-
tact the electric medical equip-
ment manufacturer for the pos-
sible 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 the
“Tire Pressure Low - Add Air” warning
appears in the vehicle information
display, one or more of your tires is sig-
nificantly under-inflated. If equipped,

WHEELS AND TIRES
Do-it-yourself8-27

the system also displays pressure of all
tires (except the spare tire) on the dis-
play screen by sending a signal from a
sensor that is installed in each wheel.
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. 2-12),
“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
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
• Most tires naturally lose air over
time.
• Tires can lose air suddenly when driven over potholes or other ob-
jects 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 af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert pro-
vides visual and audible signals out-
side the vehicle for inflating the tires
to the recommended COLD tire pres-
sure. For additional information, see
“TPMS with Easy-Fill Tire Alert” (P. 5-7).
If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
tional information, see “Checking tire
pressure” (P. 8-31).
Set the tire pressure to the normal
cold tire inflation pressure when the
vehicle speed or load is reduced.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.

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. certification
label. The vehicle weight capac-
ity is indicated on the Tire and
Loading Information label (if so
equipped). Do not load your ve-
hicle beyond this capacity. Over-
loading your vehicle may result
in reduced tire life, unsafe oper-
ating conditions due to prema-
ture tire failure, or unfavorable
handling characteristics and
could also lead to a serious
accident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components.
•Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.
•Increase the cold tire inflation
pressure as indicated in "Check-
ing tire pressure" in this section
when using the tires specified
by NISSAN above 100 mph
(162 km/h) where it is legal to do
so (on a race track for example).
Failure to increase the cold tire
inflation pressure may result in
tire failure, loss of control and
possible injury. Af ter such use,
readjust tire pressure.
• 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.
