fer to “Head restraints/headrests” in
this section.
If the seating position does not have
an adjustable head restraint/headrest
(if so equipped) and it is interfering with
the proper child restraint fit, try an-
other seating position or a different
child restraint.3. Route the seat belt tongue through thechild restraint and insert it into the
buckle until you hear and feel the latch
engage. Be sure to follow the child re-
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 in-
stallation only). For additional informa-
tion, refer to “Installing top tether strap”
in this section. Do not install child restraints that re-
quire the use of a top tether strap in
seating positions that do not have a
top tether anchor.

8. Af ter attaching the child restraint, testit 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 re-
straint 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 4 through 8.
10. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should illuminate. If this light is not illu-
minated, refer to “Front passenger air
bag and status light” in this section.
Move the child restraint to another
seating position. Have the system
checked. It is recommended that you
visit a NISSAN dealer for this service.
Af ter the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

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.
BOOSTER SEATS

air bag OFF for specified child restraints as
required by the regulations. Failing to prop-
erly secure child restraints and to use the
ALR mode may allow the restraint to tip or
move in a collision or sudden stop. This can
also result in the passenger air bag inflat-
ing in a crash instead of being OFF. For
additional information about proper use
and installation, refer to “Child restraints” in
this section.
If the front passenger seat is not occupied,
the front 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 de-
tected by the occupant classification sen-
sor. 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 re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag is automatically turned OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the air bag is OFF),it could be that the person is a small adult,
or is not sitting on the seat properly or not
using the seat belt 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, de-
pending on the size of the child and the
type of child restraint being used. If the air
bag status light is not illuminated (indicat-
ing 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 occu-
pant is positioned properly. If the air bag
status light is still not illuminated, reposi-
tion 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, it is
recommended that you take your vehicle
to a NISSAN dealer. A NISSAN dealer can
check system status by using a special
tool. However, until you have confirmed
with a dealer that your air bag is working
properly, reposition the occupant or child
restraint in a rear seat.The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the front passenger seat status. This is nor-
mal system operation and does not indi-
cate a malfunction.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will be illuminated (blinking or
steadily lit). Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Normal operation
In order for the occupant classification
sensor system to classif y the front passen-
ger based on weight, please follow the pre-
cautions 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.

systems:
∙ Vehicle security system
∙ NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors or trunk when the system
is armed. It is not, however, a motion detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.
The system helps deter vehicle thef t but
cannot prevent it, nor can it prevent the thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys in the vehicle, and
always lock the vehicle when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t protection
features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Remove the Intelligent Key from the ve- hicle.
3. Close all doors. Lock all doors. The doors can be locked with the Intelligent
Key, door handle request switch, or me-
chanical key.

4. Confirm that thesecurity indica-
tor light stays on for about 30 seconds.
The vehicle security system is now pre-
armed. The vehicle security system will
automatically shif t into the armed
phase. The
security light begins
to flash once every three seconds. If
during the pre-armed phase one of the
following occurs, the system will not
arm:
∙ Any door is unlocked with the mechani- cal key, the Intelligent Key or door re-
quest switch.
∙ Ignition switch is placed in ACC or ON position.
∙ If the key is turned slowly when lock-
ing the door, the system may not arm.
Furthermore, if the key is turned be-
yond the vertical position toward the
unlock position to remove the key,
the system may be disarmed when
the key is removed. If the indicator
light fails to glow for a period of time,
unlock the door once and lock it
again. ∙
Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors closed and
locked with the ignition switch placed
in the LOCK position. When placing
the ignition switch in the ACC or ON
position, the system will be released.
Vehicle security system activation
The vehicle security system will give the
following alarm:
∙ The headlights blink and the horn sounds intermittently.
∙ The alarm automatically turns off af ter a period of time. However, the alarm
reactivates if the vehicle is tampered
with again. The alarm can be shut off by
unlocking the driver’s door or trunk lid
with the key, or by pressing the
button on the Intelligent Key.
The alarm is activated by:
∙ opening the door or trunk lid without using the key or Intelligent Key (even if
the door is unlocked by releasing the
door inside lock switch).
How to stop an activated alarm
The alarm stops only by unlocking a door
or the trunk with the mechanical key, push- ing the
button on the Intelligent Key,
or pushing the request switch on the driv-
er’s or passenger’s door with the Intelligent
Key in range of the door handle.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of a 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 procedures:
1. Leave the ignition switch placed in the ON position for approximately 5 sec-
onds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat Steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
