Failure to follow the warnings and in-
structions for proper use of the ProPI-
LOT Assist system could result in seri-
ous injury or death.
∙ ProPILOT Assist is not a self-drivingsystem. Within the limits of its capa-
bilities, as described in this manual, it
helps the driver with certain driving
activities.
∙ The ProPILOT Assist system is not a replacement for proper driving proce-
dures and is not designed to correct
careless, inattentive or absent-
minded driving. ProPILOT Assist will
not always steer the vehicle to keep it
in the lane. The ProPILOT Assist sys-
tem is not designed to prevent loss of
control. It is the driver’s responsibility
to stay alert, drive safely, keep the ve-
hicle in the traveling lane, and be in
control of the vehicle at all times. ∙ There are limitations to the ProPILOT
Assist system capability. The ProPI-
LOT Assist system does not function
in all driving, traffic, weather, and road
conditions. It is the driver’s responsi-
bility to stay alert, drive safely, keep
the vehicle in the traveling lane, and
be in control of the vehicle at all times.
∙ The ProPILOT Assist system is only an aid to assist the driver and is not a
collision warning or avoidance device.
∙ The ProPILOT Assist system is for highway use only and is not intended
for city driving. Failure to apply the
brakes or steer the vehicle when nec-
essary may result in a serious
accident.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Never take your hands off the steering wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
∙ Never unfasten your safety belt when using ProPILOT Assist. Doing so auto-
matically cancels the ProPILOT Assist

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pres-
sure 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 signifi-
cantly under-inflated. If equipped, the sys-
tem also displays pressure of all tires (ex-
cept the spare tire) on the display screen by
sending a signal from a sensor that is in-
stalled in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will ac-
tivate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.
WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ If the low tire pressure warning light illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure-
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light still illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service.
∙ When replacing a wheel without the TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately one 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 these services.
∙ Replacing tires with those not origi- nally specified by NISSAN could affect
the proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
FLAT TIRE
In case of emergency6-3

If you wax the surface of the hood, be care-
ful not to let wax get into the washer nozzle
D. This may cause clogging or improper
windshield-washer operation. If wax gets
into the nozzle, remove it with a needle or
small pin
C. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is ap-
plied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
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.
For additional information re-
garding brake inspections, refer to the ap-
propriate maintenance schedule informa-
tion in the "Maintenance and schedules"
section of this manual.

∙ The original tires have built-intread 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 because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal 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 recom-
mended 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 Information”
(Canada) in the Warranty Infor-
mation 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. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.
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 Dynamic
Control (VDC) system, ground clear-
ance, body-to-tire clearance, tire
chain clearance, speedometer cali-
bration, 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 four tires that were the
same size and you are only replacing
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 condi-
tions and cause an accident and per-
sonal injury. ∙ If the wheels are changed for any rea-
son, 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 wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section of
this manual.
∙ When replacing a wheel without the TPMS, such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main 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 affect
the proper operation of the TPMS.
