INTELLIGENT LANE INTERVENTION
SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the Intelligent Lane Intervention
system. Failure to follow the warnings
and instructions for proper use of the
Intelligent Lane Intervention system
could result in serious injury or death.
∙ The Intelligent Lane Intervention sys-
tem may activate if you change lanes
without first activating your turn sig-
nal or, for example, if a construction
zone directs traffic to cross an exist-
ing lane marker. If this occurs you may
need to apply corrective steering to
complete your lane change.
∙ Because the Intelligent Lane Interven-
tion may not activate under the road,
weather, and lane marker conditions
described in this section, it may not
activate every time your vehicle be-
gins to leave its lane and you will need
to apply corrective steering.∙ When the Intelligent Lane Interven-
tion system is operating, avoid exces-
sive or sudden steering maneuvers.
Otherwise, you could lose control of
the vehicle.
∙ The Intelligent Lane Intervention sys-
tem will not operate at speeds below
approximately 70 km/h (45 mph) or if
it cannot detect lane markers.
∙ Do not use the Intelligent Lane Inter-
vention system under the following
conditions as it may not function
properly:
– During bad weather (rain, fog,
snow, etc.).
– When driving on slippery roads,
such as on ice or snow.
– When driving on winding or un-
even roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshif t or
temporary lane.
– When driving on roads where the
lane width is too narrow.– When driving without normal tire
conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-
standard wheels).
– When the vehicle is equipped with
non-original brake parts or sus-
pension parts.
– When you are towing a trailer or
other vehicle.

Intervention system could detect
these items as lane markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the vehicle
in front of you, which obstructs the
lane camera unit detection range.
– When rain, snow or dirt adheres to
the windshield in front of the lane
camera unit.

WARNING
To ensure proper operation of the
passenger’s NISSAN Advanced Air Bag
System, please observe the following
items.
∙ Do not allow a passenger in the rearseat to push or pull on the seatback
pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing press- ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.
∙ Make sure that there is no object placed under the front passenger
seat. ∙ Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.
∙ If a forward facing child restraint is installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
and passenger knee air bag may de-
ploy in a collision. Also the front pas-
senger air bag status light may not
illuminate. For additional information
about installing and using child re-
straints, refer to "Child restraints" in
this section.
∙ Confirm the operating condition with the front passenger air bag status
light.
∙ If you notice that the front passenger air bag status light is not operating as
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service. ∙ Until you have confirmed with a
dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.
∙ Do not position the front passenger seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
1-54Safety—Seats, seat belts and supplemental restraint system

may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.
The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensors and occupant classifi-
cation sensor (weight sensor). Inflator op-
eration is based on the severity of a colli-
sion and seat belt usage for the driver. For
the front passenger, the occupant classifi-
cation sensor is also monitored. Based on
information from the sensor, only one front
air bag may inflate in a crash, depending on
the crash severity and whether the front
occupants are belted or unbelted. Addi-
tionally, the front passenger air bag and
passenger knee air bag may be automati-
cally turned off under some conditions, de-
pending on the weight detected on the
front passenger seat and how the seat belt
is used. If the front passenger air bag and
passenger knee air bag are OFF, the front
passenger air bag status light will be illumi-
nated. For additional information, refer to
“Front passenger air bag and status light” inthis section. One front air bag inflating does
not indicate improper performance of the
system.
If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact NISSAN. Con-
tact information is contained in the front of
this Owner’s Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by the re-
lease of smoke. This smoke is not harmful
and does not indicate a fire. Care should be
taken to not inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.
Front air bags, along with the use of seat
belts, help to cushion the impact force on
the face and chest of the front occupants.
They can help save lives and reduce seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front passenger seated upright
as far as practical away from the steering
wheel or instrument panel. The front air
bags inflate quickly in order to help protect
the front occupants. Because of this, the
force of the front air bag inflating can in-
crease the risk of injury if the occupant is
too close to, or is against, the front air bag
module during inflation.
The front air bags deflate quickly af ter a
collision.
The front air bags operate only when the
ignition switch is placed in the ON posi-
tion.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

Front passenger air bag and status light
WARNING
The front passenger air bag and pas-
senger knee air bag are designed to au-
tomatically turn OFF under some condi-
tions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt, and child restraints is
necessary for most effective protec-
tion. Failure to follow all instructions in
this manual concerning the use of
seats, seat belts, and child restraints
can increase the risk or severity of in-
jury in an accident.Status light
The front passenger seat is equipped with
an occupant classification sensor (weight
sensor) that turns the front passenger air
bag and passenger knee air bag on or off
depending on the weight applied to the
front passenger seat. The status of the
front passenger air bag (ON or OFF) is indi-
cated by the front passenger air bag status
light
which is located on the instru-
ment panel.
Af ter the ignition switch is placed in the
"ON" position, the front passenger air bag
status light on the instrument panel illumi-
nates for about 7 seconds and then turns
off or remains illuminated depending on
the front passenger seat occupied status.
The light operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND PASSENGER KNEE
AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or Small Adult in
front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark)ACTIVATED
In addition to the above, certain objects
placed on the front passenger seat may
also cause the light to operate as de-
scribed above depending on their weight. For additional information, refer to “Normal
operation” and “Troubleshooting” in this
section.
LRS3091
1-56Safety—Seats, seat belts and supplemental restraint system

Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. If the front passenger air bag is OFF,
it will not inflate in a crash. The driver air bag
and other air bags in your vehicle are not
part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requir-
ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the
seat by weight. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions is on the seat, its weight and the
child’s weight can be detected and cause
the air bag to turn OFF.Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the front passenger air bag and pas-
senger knee air bag to be automatically
turned OFF. For small adults it may be
turned OFF, however if the occupant takes
his/her weight off the seat cushion (for ex-
ample, by not sitting upright, by sitting on
an edge of the seat, or by otherwise being
out of position), this could cause the sensor
to turn the air bag OFF. Always be sure to be
seated and wearing the seat belt properly
for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag and passenger knee air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure child
restraints and to use the ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag and passenger knee
air bag inflating in a crash instead of beingOFF. For additional information about
proper use and installation, refer to “Child
restraints” in this section.
If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag are designed not to inflate in a
crash. However, heavy objects placed on
the seat could result in air bag inflation,
because of the object’s weight detected by
the occupant classification sensor. Other
conditions could also result in air bag infla-
tion, such as if a child is standing on the
seat, or if two children are on the seat, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag and passenger knee air bag
are automatically turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the front passen-
ger air bag and passenger knee air bag are
OFF), it could be that the person is a small
adult, or is not sitting on the seat properly
or not using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status
