WARNING
Child restraint anchorages are de-
signed to withstand only those loads
imposed by correctly fitted child re-
straints. Under no circumstances are
they to be used to attach adult seat
belts, or other items or equipment to
the vehicle. Doing so could damage the
child restraint anchorages. The child re-
straint will not be properly installed us-
ing the damaged anchorage, and a
child could be seriously injured or killed
in a collision.

FORWARD-FACING CHILD
RESTRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must be
used when installing a child restraint.
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 pas-
senger air bag. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined 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. Follow these steps to install a forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front passen-
ger 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 seat-
back.
If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect child restraint fit. If the head
restraint/headrest (if so equipped) is
removed, store it in a secure place. Be
sure to reinstall the head
restraint/headrest (if so equipped)
when the child restraint is removed.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rearseat to push or pull on the seatback
pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 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 under the front passenger
seat.
∙ 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
installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system 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 in-
formation about installing and using
child restraints, refer to "Child re-
straints" 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
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service.
∙ Until you have confirmed with a dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.

the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
