BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the BSW system. Failure to op-
erate the vehicle in accordance with
these system limitations could result
in serious injury or death.
• The BSW system cannot detect all vehicles 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, lowheight 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 adja- cent lane at a speed approxi-
mately 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 sensor’s detection zone is designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect
vehicles in an adjacent lane. When
driving in a narrow lane, the radar
sensors may detect vehicles driving
two lanes away.
• The radar sensors are designed to ignore most stationary objects;
however, objects such as guardrails,
walls, foliage and parked vehicles
may occasionally be detected. This
is a normal operation condition.
• The following conditions may re- duce the ability of the radar to de-
tect other vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt/snow build-up onthe 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.
5-40Starting and driving

•The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
•Tires degrade with age and
use. Have tires, over 6 years old
checked by a qualified techni-
cian, because some tire dam-
age may not be obvious. Re-
place the tires as necessary to
prevent tire failure and pos-
sible personal injury.
•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. For ad-
ditional information, refer to “Specifica-
tions” in the “Technical and consumerinformation” section of this manual for rec-
ommended types and sizes of tires and
wheels.
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. Plac-
ing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an ac-
cident 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
interference with the brake discs.
Such interference can lead to de-
creased braking efficiency and/or
early brake pad/shoe wear. For ad-
ditional information on wheel-off
set dimensions, refer to “Wheels and
tires” in the “Technical and con-
sumer information” section of this
manual.
• When replacing a wheel without the TPMS such as the spare tire, the
TPMS will not function when a wheel
is replaced, the TPMS will not func-
tion and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on af-
ter 1 minute. It is recommended that
you visit a NISSAN certified LEAF
dealer for this service.
• Replacing tires with those not origi- nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
