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 cer-
tain 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 sen-
sors 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 occasionally be detected. This is
a normal operation condition.
• The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on
the vehicle •
Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
• Excessive noise (for example, audio
system volume, open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.
Starting and driving5-51

–When your vehicle or the vehicle
or pedestrian ahead moves
quickly or significantly such that
the system cannot detect and re-
act in time (for example, pedes-
trian moving quickly toward the
vehicle at close range, vehicle cut-
ting in, changing lanes, making a
turn, steering abruptly, sudden
acceleration or deceleration).
– When the vehicle or pedestrian is
offset from the vehicle’s forward
path.
– If the speed difference between
the two vehicles is small.
– The pedestrian’s profile is par-
tially obscured or unidentifiable;
for example, due to transporting
luggage, pushing a stroller, wear-
ing bulky or very loose-fitting
clothing or accessories, or being
in a unique posture (such as rais-
ing hands).
– There is poor contrast of a person
to the background, such as having
clothing color or pattern which is
similar to the background.
– For approximately 15 seconds af-
ter starting the engine. –
If the vehicle ahead has a unique
or unusual shape, extremely low
or high clearance heights, or un-
usual cargo loading or is narrow
(for example, a motorcycle).
– When the vehicle or pedestrian is
located near a traffic sign, a reflec-
tive area (for example, water on
road), or is in a shadow.
– When multiple pedestrians are
grouped together.
– When the view of the pedestrian is
obscured by a vehicle or other
object.
– While towing a trailer or other
vehicle.
• The system performance may be de-
graded in the following conditions:
– The vehicle is driven on a slippery
road.
– The vehicle is driven on a slope.
– Excessively heavy baggage is
loaded in the rear seat or the
cargo area of your vehicle.
• The system is designed to automati-
cally check the sensor’s (radar and
camera) functionality, within certain
limitations. The system may not de-
tect some forms of obstruction of the
sensor area such as ice, snow or stickers, for example. In these cases,
the system may not be able to warn
the driver properly. Be sure that you
check, clean and clear sensor areas
regularly.
• In some road and traffic conditions,
the AEB with Pedestrian Detection
system may unexpectedly apply par-
tial braking. When acceleration is
necessary, depress the accelerator
pedal to override the system.
• The AEB with Pedestrian Detection
system may operate when a pattern,
object, shadow or lights are detected
that are similar to the outline of ve-
hicles or pedestrians, or if they are
the same size and position as a ve-
hicle or motorcycle’s tail lights.
• The system may keep operating
when the vehicle ahead is turning
right or lef t.
• The system may operate when your
vehicle is approaching and passing a
vehicle ahead.
•
Depending on the road shape (curved
road, entrance and exit of the curve,
winding road, lane regulation, under
construction, etc.), the system may
operate temporarily for the oncoming
vehicle in front of your vehicle.

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. •
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 wear. For additional information
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 sys-
tem reset as soon as possible. It is
recommended 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. It is
recommended that you visit 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.

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 auto-
matic car wash since it may get
caught.
Emergency tire puncture repair kit
(if so equipped)
The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire
punctures.
If possible, have the vehicle towed to a fa-
cility that can repair or replace the flat tire.
Using the emergency tire puncture repair
kit may cause a malfunction of the tire
pressure sensor and cause the low tire
pressure warning light to illuminate. For additional information, see “Flat tire”
(P. 6-3).
NOTE:
For models with the emergency tire
puncture repair kit, a spare tire, jack
and rod are not equipped as
standard.
