Installing top tether strap
First, secure the child restraint with the
LATCH lower anchors (2nd row captain’s
or bench outboard seating positions only).
1. If necessary, raise or remove the headrestraint 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 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.
FORWARD-FACING CHILD RE-
STRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
. The three-point seat belt with Auto-
matic Locking Retractor (ALR) must
be used when installing a child re-
straint. Failure to use the ALR mode
will result in the child restraint not
being properly secured. The restraint
could tip over or be loose and cause
injury to a child in a sudden stop or
collision. Also, it can change the
operation of the front passenger air
bag. See “Front passenger air bag
and status light” (P.1-59)
. When installing a child restraint sys-
tem in the 3rd center position, both
the center seat belt connector tongue
and buckle tongue must be secured.
See “3rd row center seat belt” (P.1-
24).

Refer to all Warnings and Cautions in the
“Child safety” and “Child restraints” sections
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child
restraint exceeds 65 lbs (29.5 kg). If the
combined weight of the child and the child
restraint is greater than 65 lbs (29.5 kg), use
the vehicle’s seat belt (not the lower an-
chors) to install the child restraint. Be sure to
follow the child restraint manufacturer’s
instructions for installation.

passenger seat:
1.If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move
the seat to the rearmost position. Child
restraints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint or headrest to obtain the
correct child restraint fit. 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/headrests” (P.1-13) for head
restraint or headrest adjustment, re-
moval and installation information.
If the seating position does not have an
adjustable head restraint or a headrest
and it is interfering with the proper child
restraint fit, try another seating position
or a different child restraint.

Forward-facing — step 3
3. Route the seat belt tongue through the child restraint and insert it into the buckle
until you hear and feel the latch engage.
Be sure to follow the child restraint
manufacturer’s instructions for belt
routing.
If the child restraint is equipped with a
top tether strap, route the top tether
strap and secure the tether strap to the
tether anchor point (rear seat installation
only). See “Installing top tether strap”
(P.1-47). Do not install child restraints
that require the use of a top tether strap
in seating positions that do not have a
top tether anchor.

Forward-facing — step 4
4. Pull the shoulder belt until the belt is fully extended. At this time, the seat belt
retractor is in the Automatic Locking
Retractor (ALR) mode (child restraint
mode). It reverts to Emergency Locking
Retractor (ELR) mode when the seat belt
is fully retracted.

Booster seat installation
CAUTION
Do not use the lap/shoulder belt Auto-
matic Locking Retractor (ALR) mode
when using a booster seat with the seat
belts.
Refer to all Warnings and Cautions in the
“Child safety”, “Child restraints” and “Boos-
ter seats” sections earlier in this section
before installing a child restraint.
Follow these steps to install a booster seat in
the rear seat or in the front passenger seat:

3. The booster seat should be positioned on the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint or headrest to obtain the
correct booster seat fit. 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
booster seat is removed. See “Head

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 bagwarning 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.
. Make sure that there is no object placed
under the front passenger seat.
Steps:
1. Adjust the seat as outlined. (See “Seats” (P.1-3).) Sit upright, leaning against the
seatback, and centered on the seat
cushion with your feet comfortably ex-
tended to the floor. 2. Make sure there are no objects on your
lap.
3. Fasten the seat belt as outlined. (See “Seat belts” (P.1-17).)
4. Remain in this position for 30 seconds allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification sensor
system locks the classification during driv-
ing so it is important that you confirm that
the front passenger is properly classified
prior to driving. Also, the occupant classifi-
cation sensor system may recalculate the
weight of the occupant when the vehicle
comes to a stop (i.e. stop light, stop sign,
etc.), so the front passenger seat occupant
should continue to remain seated as out-
lined above.
Troubleshooting:
If you think the front passenger air bag
status light is incorrect: 1. If the light is ON with no front passenger and no objects on the front
passenger seat:
This may be due to the following conditions
that may be interfering with the weight
