straint 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 installa-
tion only). For additional information, see
“Installing top tether strap” (P. 1-39) 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.
4. Pull the shoulder belt until the belt is fullyextended. At this time, the seat belt re-
tractor is in the ALR mode (child restraint

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 restraint will not be properly installed
using the damaged anchorage, and a
child could be seriously injured or killed
in a collision.
BOOSTER SEATS
For additional information on installing a
booster seat in your vehicle, follow the in-
structions outlined in this section.
Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured or killed in a sudden stop or col-
lision greatly increases:
– Make sure the shoulder portion of
the belt is away from the child's face
and neck and the lap portion of the
belt does not cross the stomach.
– Make sure the shoulder belt is not
behind the child or under the child's
arm.
– A booster seat must only be installed
in a seating position that has a lap/
shoulder belt.

1.If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manu-
facturer’s instructions. 3. The booster seat should be positioned
on the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional informa-
tion, see “Head restraints/headrests”
(P. 1-7) If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper booster
seat fit, try another seating position or a
different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure
to follow the booster seat manufactur-
er’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up ex-
tra slack. Be sure the shoulder belt is
positioned across the top, middle por-
tion of the child’s shoulder. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” (P. 1-15).

Front passenger position

Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF when the
vehicle is operated under some conditions
as described below in accordance with U.S.
regulations. If the front passenger air bag
and front passenger supplemental knee
air bag are 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 requir-
ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the
seat by weight. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag and front pas-
senger supplemental knee 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 andthe child’s weight can be detected and
cause the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the front passenger air bag and
front passenger supplemental knee air
bag to be automatically turned OFF. For
small adults it may be turned OFF, however
if the occupant takes his/her weight off the
seat cushion (for example, by not sitting
upright, by sitting on an edge of the seat, or
by otherwise being out of position), this
could cause the sensor to turn the front
passenger air bag and front passenger
supplemental knee air bag OFF. Always be
sure to be seated and wearing the seat belt
properly for the most effective protection
by the seat belt and supplemental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag and front passenger supplemental
knee air bag OFF for specified child re-
straints as required by the regulations. Fail-ing to properly secure child restraints and
to use the ALR mode may allow the re-
straint to tip or move in a collision or sud-
den stop. This can also result in the passen-
ger air bag and front passenger
supplemental knee air bag inflating in a
crash instead of being OFF. For additional
information, see “Child restraints” (P. 1-22).
If the front passenger seat is not occupied,
the front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed not to inflate in a crash. However,
heavy objects placed on the seat could re-
sult in air bag inflation, because of the ob-
ject’s weight detected by the occupant
classification 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 front passenger air bag status
light, you can monitor when the front pas-
senger air bag and front passenger
supplemental knee air bag are automati-
cally turned OFF.
