INFINITI G35 2006 Repair Manual

The INFINITI advanced air bag system has
dual stage inflators. It also monitors infor-
mation from the crash zone sensor, the
diagnosis sensor unit, seat belt buckle
switches, occupant classification sensor
(pressure sensor) and passenger seat belt tension sensor. Inflator operation is
based on the severity of a collision and
seat belt usage for the driver. For the
front passenger, it additionally monitors
the weight of an occupant or object on
the seat and seat belt tension. Based on information from the sensors, only one
front air bag may inflate in a crash, de-
pending on the crash severity and
whether the front occupants are belted or
unbelted. Additionally, the front pas-
senger air bag may be automatically
turned OFF under some conditions, de-
pending on the pressure detected on the
passenger seat and how the seat belt is
used. If the front passenger air bag is
OFF, the passenger air bag status light
will be illuminated (if the seat is unoccu-
pied, the light will not be illuminated, but
the air bag will be off). See ªFront pas-
senger air bag and status lightº later in
this section for further details. One front
air bag inflating does not indicate im-
proper performance of the system.
If you have any questions about your air
bag system, contact an INFINITI dealer. If
you are considering modification of your
vehicle due to a disability, you may also
contact an INFINITI dealer. Contact infor-
mation is contained in the front of this
Owner's Manual.
When a supplemental front air bag in-
flates, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to in- SSS0418

hale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air
promptly.
Supplemental 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 serious injuries. However, an
inflating front air bag may cause facial
abrasions or other injuries. Front air bags
do not provide restraint to the lower
body.
Even with INFINITI advanced air bags, seat
belts should be correctly worn and the
driver and passenger seated upright as
far as practical away from the steering
wheel or instrument panel. The supple-
mental front air bags inflate quickly in or-
der to help protect the front occupants.
Because of this, the force of the front air
bag inflating can increase the risk of in-
jury if the occupant is too close to, or is
against, the air bag module during infla-
tion.
The air bag will deflate quickly after a col-
lision. The supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition switch to the ON
position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
after about 7 seconds if the system is op-
erational.
Front passenger air bag and
status light
WARNING The front passenger air bag is designed to
automatically 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 protection. Failure to follow SSS0367

all instructions in this manual concerning
the use of seats, seat belts and child re-
straints can increase the risk or severity of
injury in an accident.
Status light:
The front passenger air bag status light
is located in the center display. The
light operates as follows:
O Unoccupied passenger seat: The is
OFF and the front passenger air bag is
OFF and will not inflate in a crash.
O Passenger seat occupied by a small
adult, child or child restraint as out-
lined in this section: The illumi-
nates to indicate that the front pas-
senger air bag is OFF and will not in-
flate in a crash.
O Occupied passenger seat and the pas-
senger meets the conditions outlined
in this section: The light is OFF to
indicate that the front passenger air
bag is operational.
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.
regulations. 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 re-
quiring the air bag to be automatically
turned OFF. Certain sensors are used to
meet the requirements.
One sensor used is the occupant classifi-
cation sensor (pressure sensor). It is in
the bottom of the front passenger seat
cushion and is designed to detect an oc-
cupant and objects on the seat by weight.
It works together with seat belt sensors
described later. For example, if a child is
in the front passenger seat, the advanced
air bag system is designed to turn the
passenger air bag OFF in accordance with
the regulations. Also, if a child restraint of
the type specified in the regulations is on
the seat, its weight and the child's weight
can be detected and cause the air bag to
turn OFF. Occupant classification sensor
operation can vary depending on the front
passenger seat belt sensors. The front passenger seat belt sensors are
designed to detect if the seat belt is
buckled and the amount of tension on the
seat belt, such as when it is in the auto-
matic locking mode (child restraint mode).
Based on the weight on the seat detected
by the occupant classification sensor and
the belt tension detected on the seat belt,
the INFINITI advanced air bag system de-
termines whether the front passenger air
bag should be automatically turned OFF
as required by the regulations.
Front passenger seat adult occupants who
are properly seated and using the seat
belt as outlined in this manual should not
cause the passenger air bag to be auto-
matically turned OFF. For small adults it
may be turned OFF, however, if the occu-
pant takes his/her weight off the seat
cushion (for example, by not sitting up-
right, 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. In addition, if the occupant improp-
erly uses the seat belt in the automatic
locking mode (child restraint mode), this
could cause the air bag to be turned OFF.
Always be sure to be seated and wearing
the seat belt properly for the most effec-
tive protection by the seat belt and
supplemental air bag.

INFINITI recommends that pre-teens and
children be properly restrained in a rear
seat. INFINITI also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat.
If this is not possible, the occupant clas-
sification sensor and seat belt sensors
are designed to operate as described
above to turn the front passenger air bag
OFF for specified child restraints as re-
quired by the regulations. Failing to prop-
erly secure child restrains and to use the
automatic locking mode (child restraint
mode) may allow the restraint to tip or
move in an accident or sudden stop. This
can also result in the passenger air bag
inflating in a crash instead of being OFF.
See ªChild restraintsº earlier in this sec-
tion for proper use and installation.
If the front passenger seat is not occu-
pied, the passenger air bag is 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 classifi-
cation sensor. Other conditions could also
result in air bag inflation, such as if a
child is standing on the seat, or if two
children are on the seat, contrary to the
instructions in this manual. Always be sure that you and all vehicle occupants
are seated and restrained properly.
Using the passenger air bag status light,
you can monitor when the front pas-
senger air bag is automatically turned OFF
with the seat occupied. The light will not
illuminate when the front passenger seat
is unoccupied.
If an adult occupant is in the seat but the
passenger air bag status light is illumi-
nated (indicating that the air bag is OFF),
it could be that the person is a small
adult, or is not sitting on the seat prop-
erly or is not using the seat belt properly.
If a child restraint must be used in the
front seat, the passenger air bag status
light may or may not be illuminated, de-
pending on the size of the child and the
type of child restraint being used. If the
passenger air bag status light is not illu-
minated (indicating that the air bag might
inflate in a crash), it could be that the
child restraint or seat belt is not being
used properly. In rare cases, the pas-
senger air bag status light will not illumi-
nate even though the air bag is OFF.
If such situations happen, properly posi-
tion and restrain the occupant or child re-
straint. Otherwise reposition the occupant or child restraint in a rear seat. If you
have any questions about whether your
passenger air bag is working as designed,
your INFINITI dealer can confirm that it is
working properly by using a special tool.
The INFINITI advanced air bag system and
passenger air bag status light will take a
few seconds to register a change in the
passenger seat status. For example, if a
large adult who is sitting in the front pas-
senger seat exits the vehicle, the passen-
ger air bag status light will change from
OFF to ON for a few seconds and then to
OFF. This is normal system operation and
does not indicate a malfunction.
If a malfunction occurs in the front pas-
senger air bag system, the supplemental
air bag warning light , located in the
meter and gauges area will blink. Have
the system checked by an INFINITI dealer.

Other supplemental front air bag precau-
tions
WARNINGO Do not place any objects on the steering
wheel pad or on the instru-ment panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause
injury if the supplemental front air bag
inflates.
O Immediately after inflation, several front
air bag system components will be hot.
Do not touch them; you may severely
burn yourself.
O No unauthorized changes should be
made to any components or wiring of the
supplemental air bag system. This is to
prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
O Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or front end structure. This could affect proper operation of the
supplemental front air bag system.
O Tampering with the supplemental front
air bag system may result in serious per-
sonal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad and
above the instrument panel or by install-
ing additional trim material around the
air bag system.
O Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat. Additionally, do not
stow any objects under the front passen-
ger seat or the seat cushion and seat-
back. Such objects may interfere with
the proper operation of the occupant
classification sensor (pressure sensor). O No unauthorized changes should be
made to any components or wiring of the
seat belt system. This may affect the
supplemental front air bag system. Tam-
pering with the seat belt system may re-
sult in serious personal injury.
O Work around and on the supplemental
front air bag system should be done by
an INFINITI dealer. Installation of elec-
trical equipment should also be done by
an INFINITI dealer. The yellow and or-
ange Supplemental Restraint System
(SRS) wiring and connectors should not
be modified or disconnected. Unautho-
rized electrical test equipment and prob-
ing devices should not be used on the air
bag system.
O A cracked windshield should be replaced
immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.
O 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
supplemental front air bag system and
guide the buyer to the appropriate sec-
tions in this Owner's Manual.
SUPPLEMENTAL SIDE AIR BAG AND
CURTAIN SIDE-IMPACT AIR BAG
SYSTEMS The supplemental side air bags are lo-
cated in the outside of the seatback of
the front seats. The supplemental curtain
side-impact air bags are located in the
side roof rails. These systems are de-
signed to meet voluntary guidelines to
help reduce the risk of injury to out-of-
position occupants. However, all of the in-
formation, cautions and warnings in this
manual still apply and must be followed.
The supplemental side air bags and cur- tain side-impact air bags are designed to
inflate in higher severity side collisions
on the side of the vehicle impacted, al-
though they may inflate if the forces in
another type of collision are similar to
those of a higher severity side impact.
They are designed to inflate on the side
where the vehicle is impacted. They may
not inflate in certain side collisions.
Vehicle damage (or lack of it) is not al-
ways an indication of proper supple-
mental side air bag and curtain side-
impact air bag operation.
When the supplemental side air bag and
curtain side-impact air bag inflate, a fairly
loud noise may be heard, followed by re-
lease 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 his-
tory of a breathing condition should get
fresh air promptly.
Supplemental side air bags, along with the
use of seat belts, help to cushion the im-
pact force on the chest of the front occu-
pants. Curtain side-impact air bags help to
cushion the impact force to the head of oc-
cupants in the front and rear outboard
seating positions. They can help save lives
and reduce serious injuries. However, an
inflating side air bag, or curtain side- SSS0190

impact air bag may cause abrasions or
other injuries. Supplemental side air bags
and curtain side-impact air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn
and the driver and passenger seated up-
right as far as practical away from the
supplemental side air bag. Rear seat pas-
sengers should be seated as far away as
practical from the door finishers and side
roof rails. The side air bags and curtain
side-impact air bag inflate quickly in
order to help protect the front occupants.
Because of this, the force of the side air
bag and curtain side-impact air bag inflat-
ing 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 and curtain side-impact
air bag will deflate quickly after the colli-
sion is over.
The supplemental side air bags and cur-
tain side-impact air bags operate only
when the ignition switch is in the ON or
START position.
After turning 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 sec-
onds if the systems are operational. WARNING O Do not place any objects near the seat-
back 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 projectiles and cause injury if
the side air bag inflates.
O Right after inflation, several side air bag
and curtain side-impact air bag system
components will be hot. Do not touch
them; you may severely burn yourself.
O No unauthorized changes should be
made to any components or wiring of the
side air bag and curtain side-impact air
bag system. This is to prevent accidental
inflation of the side air bag and curtain
side-impact air bag or damage to the
side air bag and curtain side-impact air
bag system.
O Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or side panel. This could affect proper operation of the
supplemental side air bag and curtain
side-impact air bag system.
O Tampering with the supplemental
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 bag.
O Work around and on the side air bag and
curtain side-impact air bag system
should be done by an INFINITI dealer. In-
stallation of electrical equipment should
also be done by an INFINITI dealer. The
SRS wiring harnesses* should not be
modified or disconnected. Unauthorized
electrical test equipment and probing
devices should not be used on the side
air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy
identification.

Pre-tensioner seat belt system
(front seats)
WARNINGO The pre-tensioner seat belt cannot be re-
used after activation. It must be replaced
together with the retractor and buckle as
a unit.
O If the vehicle becomes involved in a fron-
tal collision but the pre-tensioner is not
activated, be sure to have the pre-
tensioner system checked and, if neces-
sary, replaced by an INFINITI dealer.
O No unauthorized changes should be
made to any components or wiring of the
pre-tensioner seat belt system. This is to
prevent accidental activation of the pre-
tensioner seat belt or damage to the pre-
tensioner seat belt operation. Tampering
with the pre-tensioner seat belt system may result in serious per-
sonal injury.
O Work around and on the pre-tensioner
system should be done by an INFINITI
dealer. Installation of electrical equip-
ment should also be done by an INFINITI
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
O If you need to dispose of the pre-
tensioner or scrap the vehicle, contact
an INFINITI dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate INFINITI Service Manual. In-
correct disposal procedures could cause
personal injury.
The front seat pre-tensioner seat belt sys-
tem activates in conjunction with the front
supplemental air bag systems. Working
with the seat belt retractor, it helps
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants. The pre-tensioner is encased with the
seat belt's retractor. These seat belts are
used the same as conventional seat belts.
When the pre-tensioner seat belt acti-
vates, smoke is released 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 his-
tory of a breathing condition should get
fresh air promptly.
If any abnormality occurs in the pre-
tensioner seat belt system, the supple-
mental air bag warning light will not
come on, will flash intermittently or will
turn on for 7 seconds and remain on after
the ignition switch has been turned to the
ON or START position. In this case, the
pre-tensioner seat belt may not function
properly. They must be checked and re-
paired. Take your vehicle to an INFINITI
dealer.
When selling your vehicle, we request
that you inform the buyer about the pre-
tensioner seat belt system and guide the
buyer to the appropriate sections in this
Owner's Manual.
