SSS0521
FRONT SEAT-MOUNTED SIDE-
IMPACT SUPPLEMENTAL AIR
BAG AND ROOF-MOUNTED
CURTAIN SIDE-IMPACT AND
ROLLOVER SUPPLEMENTAL AIR
BAG SYSTEMS
The side air bags are located in the outside
of the seatback of the front seats. The
curtain air bags are located in the side roof
rails. All of the information, cautions and
warnings in this manual apply and must be
followed. The side air bags and curtain air
bags are designed to inflate in higher
severity side collisions, although they may inflate if the forces in another type of
collision are similar to those of a higher
severity impact. They are designed to inflate
on the side where the vehicle is impacted.
They may not inflate in certain side collisions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental side air
bag and curtain side-impact air bag opera-
tion.
When side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by release of smoke. 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.
Side air bags, along with the use of seat
belts, help to cushion the impact force on the
chest of the front occupants. Curtain air
bags help to cushion the impact force to the
head of occupants in the front and rear
outboard seating positions in all rows. They
can help save lives and reduce serious
injuries. However, an inflating side air bags
and curtain air bags may cause abrasions or

other injuries. Side air bags and curtain air
bags do not provide restraint to the lower
body.
The seat belts should be correctly worn and
the driver and passenger seated upright as
far as practical away from the side air bag.
Rear seat passengers should be seated as far
away as practical from the door finishers
and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of this,
the force of the side air bags and curtain air
bags inflating can increase the risk of injury if
the occupant is too close to, or is against,
these air bag modules during inflation. The
side air bag will deflate quickly after the
collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags
operate only when the ignition switch is in
the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The air bag warning light
will turn off after about 7 seconds if the
systems are operational.
WARNING
.Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door
finisher and the front seat. Such
objects may become dangerous pro-
jectiles and cause injury if side air bag
inflates.
. Right after inflation, several side air
bags and curtain air bag system
components will be hot. Do not touch
them; you may severely burn your-
self.
. No unauthorized changes should be
made to any components or wiring of
side air bag and curtain air bags. This
is to prevent damage to or accidental
inflation of the side air bag and
curtain air bag systems.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
side air bag and curtain air bag
systems.
. Tampering with the air bag system
may result in serious personal injury.
For example, do not change the front seats by placing material near the
seatback or by installing additional
trim material, such as seat covers,
around the side air bags.
. It is recommended you visit an
INFINITI retailer for work on and
around the side air bag and curtain
air bag. It is also recommended you
visit an INFINITI retailer for installa-
tion of electrical equipment. The
Supplemental Restraint System
(SRS) wiring harnesses* should not
be modified or disconnected. Un-
authorized electrical test equipment
and probing devices should not be
used on the side-impact air bag
system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
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 BELTS WITH PRETEN-
SIONERS (front seats)
WARNING
.The pretensioners cannot be reused
after activation. They must be re-
placed together with the retractor
and buckle as a unit.
. If the vehicle becomes involved in a
collision but a pretensioner is not
activated, be sure to have the pre-
tensioner system checked and, if
necessary, replaced. It is recom-
mended you visit an INFINITI retailer
for this service.
. No unauthorized changes should be
made to any components or wiring of
the pretensioners. This is to prevent
damage to or accidental activation of
the pretensioner system. Tampering
with the pretensioner system may
result in serious personal injury.
. It is recommended you visit an
INFINITI retailer for work on and
around the pretensioner system. It is
also recommended you visit an
INFINITI retailer 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 or scrap the vehicle, it is
recommended you visit an INFINITI
retailer for this service. Correct pre-
tensioner disposal procedures are set
forth in the appropriate INFINITI
Service Manual. Incorrect disposal
procedures could cause personal in-
jury.
The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat
belt retractor, it helps tighten the seat belt
when the vehicle becomes involved in certain
types of collisions, helping to restrain front
seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used the
same way as conventional seat belts.
When a pretensioner seat belt activates,
smoke is released and a loud noise may be
heard. The smoke is not harmful, and it 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 pretensioner activation, load limiters
allow the seat belt to release webbing (if necessary) to reduce forces against the
chest.
The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. (See “Supplemental
air bag warning light” (P.1-59) for more
details.) If the operation of the supplemental
air bag warning light indicates there is a
malfunction, have the system checked. It is
recommended you visit an INFINITI retailer
for this service.
When selling your vehicle, we request that
you inform the buyer about the seat belt
pretensioners and guide the buyer to the
appropriate sections in this Owner’s Manual.

an accident. To help avoid injury to
yourself or others, have your vehicle
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for
this service.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain air
bags and pretensioners are designed to
activate on a one-time-only basis. As a
reminder, unless it is damaged, the supple-
mental air bag warning light will remain
illuminated after inflation has occurred.
These systems should be repaired and/or
replaced as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioners and related
parts should be pointed out to the person
conducting the maintenance. The ignition
switch should always be in the LOCK
position when working under the hood or
inside the vehicle.
WARNING
. Once a front air bag, side air bag, or
curtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner must also
be replaced. The air bag module and
pretensioner should be replaced. It is recommended you visit an INFINITI
retailer for this service. However, the
air bag module and pretensioner
system cannot be repaired.
. The front air bag, side air bag, curtain
air bag and the pretensioner system
should be inspected if there is any
damage to the front end or side
portion of the vehicle. It is recom-
mended you visit an INFINITI retailer
for this service.
. If you need to dispose of the supple-
mental air bag or pretensioner or
scrap the vehicle, it is recommended
you visit an INFINITI retailer. Correct
supplemental air bag and seat belt
pretensioner system disposal proce-
dures are set forth in the appropriate
INFINITI Service Manual. Incorrect
disposal procedures could cause per-
sonal injury.
. If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked by an INFINITI retailer to
verify it is still functioning correctly.
The OCS should be checked even if no
air bags deploy as a result of the
impact. Failure to verify proper OCS
function may result in an improper air
bag deployment resulting in injury or
