∙When the BSW system is turned on,
the BSW/RCTA indicator (white) in the
vehicle information display illumi-
nates.
BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the BSW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The BSW system cannot detect all ve- hicles under all conditions.
∙ The radar sensors may not be able to detect and activate BSW when certain
objects are present such as:
– Pedestrian, bicycles, animals.
– Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
– Oncoming vehicles.
– Vehicles remaining in the detec- tion zone when you accelerate
from a stop. – A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
– A vehicle approaching rapidly from behind.
– A vehicle which your vehicle over- takes rapidly.
– A vehicle that passes through the detection zone quickly.
– When overtaking several vehicles in a row, the vehicles af ter the first
vehicle may not be detected if they
are traveling close together.
∙ The radar sensors’ detection zone is designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect ve-
hicles in an adjacent lane. When driv-
ing in a narrow lane, the radar sensors
may detect vehicles driving two lanes
away.
∙ The radar sensors are designed to ig- nore most stationary objects; how-
ever, objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a nor-
mal operation condition. ∙ The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt build-up on the vehicle
∙ Do not attach stickers (including transparent material), install accesso-
ries or apply additional paint near the
radar sensors. These conditions may
reduce the ability of the radar to de-
tect other vehicles.
∙ Excessive noise (for example, audio system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

Tire wear and damage
1. Wear indicator
2. Location mark
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 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. Rec-
ommended types and sizes are shown in
“Wheels and tires” in the “Technical and con-
sumer information” 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, VDC system,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speedom-
eter calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could re-
sult in serious personal injury.

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
areas where it is used during winter.
Spare tire (TEMPORARY USE ONLY
spare tire)
When replacing a wheel without the TPMS
such as the spare tire, the TPMS will not
function. Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used. Otherwise, your vehicle could be
damaged or involved in an accident:
WARNING
∙ The spare tire should be used for
emergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible tire
or differential damage.
∙ Drive carefully while the TEMPORARY USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
∙ Periodically check spare tire inflation pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire
at 420 kPa, 4.2 bar (60 psi).
∙ With the TEMPORARY USE ONLY spare tire installed do not drive the 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
rear wheels and the original tire used
on the front wheels (drive wheels). ∙ 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.
∙ Do not tow a trailer when the TEMPO- RARY USE ONLY spare tire is installed.
CAUTION
∙ Do not use tire chains on a TEMPO-RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause
damage to the vehicle.
∙ Because the TEMPORARY USE ONLY spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.
