●Be sure the seat belt tongue is securely
fastened to the proper buckle.
● Do not wear the seat belt inside out or
twisted. Doing so may reduce its
effectiveness.
● Do not allow more than one person to
use the same seat belt.
● Never carry more people in the vehicle
than there are seat belts.
● If the seat belt warning light glows con-
tinuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked. It is recommended that you
visit a NISSAN dealer for this service.
● No changes should be made to the seat
belt system. For example, do not modify
the seat belt, add material, or install
devices that may change the seat belt
routing or tension. Doing so may affect
the operation of the seat belt system.
Modifying or tampering with the seat
belt system may result in serious per-
sonal injury. ●
Once seat belt pretensioner(s) have ac-
tivated, they cannot be reused and must
be replaced together with the retractor.
It is recommended that you visit a
NISSAN dealer for this service.
● All seat belt assemblies, including re-
tractors and attaching hardware, should
be inspected after any collision. It is
recommended that you visit a NISSAN
dealer for this service. NISSAN recom-
mends that all seat belt assemblies in
use during a collision be replaced un-
less the collision was minor and the
belts show no damage and continue to
operate properly. Seat belt assemblies
not in use during a collision should also
be inspected and replaced if either
damage or improper operation is noted.
● All child restraints and attaching hard-
ware should be inspected after any col-
lision. Always follow the restraint
manufacturer’s inspection instructions
and replacement recommendations.
The child restraints should be replaced
if they are damaged.

PRECAUTIONS ON SRS
This SRS section contains important information
concerning the following systems:
● Driver and front passenger supplemental
front-impact air bag (NISSAN Advanced Air
Bag System)
● Front seat-mounted side-impact supple-
mental air bag
● Roof-mounted curtain side-impact and roll-
over supplemental air bag
● Seat belt with pretensioner(s) (front seats)
Supplemental front-impact air bag system
The NISSAN Advanced Air Bag System can help
cushion the impact force to the head and chest of
the driver and front passenger in certain frontal
collisions.
Front seat-mounted side-impact supple-
mental air bag system
This system can help cushion the impact force to
the chest area of the driver and front passenger in
certain side-impact collisions. The side air bags
are designed to inflate on the side where the
vehicle is impacted. Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact force to
the head of occupants in front and rear outboard
seating positions in certain side-impact colli-
sions. The curtain air bags are designed to inflate
on the side where the vehicle is impacted. In a
rollover, the curtain air bags are designed to
inflate and remain inflated for a short time.
The SRS is designed to
supplementthe crash
protection provided by the driver and front pas-
senger seat belts and is not a substitutefor
them. Seat belts should always be correctly worn
and the occupant seated a suitable distance
away from the steering wheel, instrument panel
and door finishers. For additional information
about instructions and precautions on seat belt
usage, refer to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is placed in the ON
position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.

WARNING
To ensure proper operation of the passen-
ger’s NISSAN Advanced Air Bag System,
please observe the following items.
●Do not allow a passenger in the rear
seat to push or pull on the seatback
pocket.
● Do not place heavy loads heavier than
2.2 lbs (1 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
between the seat cushion and center
console or between the seat cushion
and the door. ●
If a forward facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem may determine the seat is occupied
and the passenger air bag may deploy
in a collision. Also the front passenger
air bag status light may not illuminate.
For additional information about in-
stalling and using child restraints, 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 de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit a NISSAN
dealer for this service.
● Until you have confirmed with a dealer
that your passenger seat occupant clas-
sification system is working properly,
position the occupants in the rear seat-
ing positions.
Safety—Seats, seat belts and supplemental restraint system1-49

●Tampering with the side air bag system
may result in serious personal injury.
For example, do not change the front
seats by placing material near the seat-
backs or by installing additional trim
material, such as seat covers, around
the side air bag.
● It is recommended that you visit a
NISSAN dealer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or cur-
tain air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the side air bag and
curtain air bag systems and guide the buyer to
the appropriate sections in this Owner’s Manual.Seat belt with pretensioner(s) (front
seats)
WARNING
● The pretensioner(s) cannot be reused
after activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
collision but pretensioner(s) are not ac-
tivated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit a NISSAN dealer for this
service.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioner(s) . Tampering with
the pretensioner system may result in
serious personal injury. ●
It is recommended that you visit a
NISSAN dealer for work on and around
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
● If you need to dispose of the preten-
sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause personal
injury.
The pretensioner system may activate with the
supplemental air bag system in certain types of
collisions. Working with the seat belt retractor,
the pretensioner(s) help tighten the seat belt
when the vehicle becomes involved in certain
types of collisions, helping to restrain front seat
occupants.
The pretensioner(s) are encased within the seat
belt retractor and to the seat belt anchor affixed
to the floor of the vehicle. These seat belts are
used the same way as conventional seat belts.
1-58Safety—Seats, seat belts and supplemental restraint system

When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
After the pretensioner(s’) activation, load limiters
allow the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
The supplemental air bag warning light
is
used to indicate malfunctions in the pretensioner
system. For additional information, refer to
Supplemental air bag warning light in this sec-
tion. If the operation of the supplemental air bag
warning light indicates there is a malfunction,
have the system checked. It is recommended that
you visit a NISSAN dealer for this service.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.
