8. After attaching the child restraint, test it before you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The
child restraint should not move more
than 1 inch (25 mm), from side to side.
Try to tug it forward and check to see if
the belt holds the restraint in place. If the
restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may
need to try a different child restraint. Not
all child restraints fit in all types of
vehicles.
9. Check to make sure the child restraint is properly secured prior to each use. If the seat belt is not locked, repeat steps 2
through 8.

10. If the child restraint is installed in the front passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should
illuminate. If this light is not illuminated,
see “Front passenger air bag and status
light” (P.1-59). Move the child restraint
to another seating position. Have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
After the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

Installing top tether strap
WARNING
In the 3rd row bench seat, a child
restraint with a top tether strap can
only be used in the outboard seating
position (right side). Do not place it in
the outboard seating position (left side)
and center position and attempt to angle
the tether strap to the outboard seating
position (right side).First, secure the child restraint with the seat
belt.
1. If necessary, raise or remove the head
restraint or headrest to position the top
tether strap over the top of the seatback.
If the head restraint or headrest is
removed, store it in a secure place. Be
sure to reinstall the head restraint or
headrest when the child restraint is
removed. See “Head restraints/head-
rests” (P.1-13) for head restraint or
headrest adjustment, removal and in-
stallation information.
2. Secure the tether strap to the tether anchor point on the back of each seat-
back (2nd row seat) or right side seat-
back (3rd row bench seat) behind the
child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. Make sure the head restraint
or headrest does not contact the top
tether strap.
If you have any questions when installing a
top tether strap on the rear seat, it is
recommended you visit an INFINITI retailer
for this service.

possible, the occupant classification sensors
are designed to operate as described above
to turn the front passenger air bag and front
passenger knee air bag OFF for specified
child restraints. Failing to properly secure
child restrains and to use the ALR mode may
allow the restraint to tip or move in an
accident or sudden stop. This can also result
in the passenger air bag and front passenger
knee air bag inflating in a crash instead of
being OFF. (See “Child restraints” (P.1-30)
for proper use and installation.)
If the front passenger seat is not occupied,
the passenger air bag and front 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 being detected by the occupant
classification sensors. 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 front passenger air bag status
light, you can monitor when the front
passenger air bag and front passenger knee
air bag are automatically turned OFF with
the seat occupied. The light will not illumi-
nate when the front passenger seat is
unoccupied.If an adult occupant is in the seat but the
front passenger air bag status light is
illuminated (indicating that the air bag and
front passenger knee air bag are OFF), it
could be that the person is a small adult, or is
not sitting on the seat properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending on
the size of the child and the type of child
restraint being used. If the front passenger
air bag status light is not illuminated (in-
dicating that the air bag might inflate in a
crash), it could be that the child restraint or
seat belt is not being used properly. Make
sure that the child restraint is installed
properly, the seat belt is used properly and
the occupant is positioned properly. If the
front passenger air bag status light is still not
illuminated, reposition the occupant or child
restraint in a rear seat.
If the front passenger air bag status light will
not illuminate even though you believe that
the child restraint, the seat belts and the
occupant are properly positioned, the sys-
tem may be sensing an unoccupied seat (in
which case the air bag is OFF). Your
INFINITI retailer can check that the system
is OFF by using a special tool. However, until
you have confirmed with your retailer that
your air bag is working properly, reposition
the occupant or child restraint in a rear seat.The INFINITI Advanced Air Bag System and
front passenger air bag status light will take
a few seconds to register a change in the
passenger seat status. However, if the seat
becomes unoccupied, the front passenger air
bag status light will remain off.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area will blink. Have the system
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation:
In order for the occupant classification
sensor system to classify the front passen-
ger based on weight, please follow the
precautions and steps outlined below:
Precautions:
. Make sure that there are no objects
weighing over 9.1 lbs (4 kg) hanging on
the seat or placed in the seatback pocket.
. Make sure that a child restraint or other
object is not pressing against the rear of
the seatback.
. Make sure that a rear passenger is not
pushing or pulling on the back of the
front passenger seat.
. Make sure that the front passenger seat
or seatback is not forced back against an
object on the seat or floor behind it.

seats by placing material near the
seatback or by installing additional
trim material, such as seat covers,
around the side air bags.
. Removing or modifying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury.
. 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 and second row
outboard 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 pretensioner system. This is to
prevent damage to or accidental
activation of the pretensioners. Tam-
pering 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 a 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
and second row outboard seats occupants.
The pretensioner is encased with the seat
belt retractor and buckle anchor. These seat
belts are used the same way as conventional
seat belts.
When a pretensioner 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.1-70) 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 pretensioner
system and guide the buyer to the appro-
priate sections in this Owner’s Manual.
