3. Secure the child restraint anchor attach-ments to the LATCH lower anchors. Check
to make sure the LATCH attachment is prop-
erly attached to the lower anchors.
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. See “Installing top tether strap” in this
section. Do not install child restraints that
require the use of a top tether strap in seat-
ing positions that do not have a top tether
anchor. 4. The back of the child restraint should be
secured against the vehicle seatback.
If the seating position does not have an
adjustable head restraint and it is interfering
with the proper child restraint fit, try another
seating position or a different child restraint.

5. For child restraints that are equipped withwebbing-mounted attachments, remove any
additional slack from the anchor attach-
ments. Press downward and rearward firmly
in the center of the child restraint with your
knee to compress the vehicle seat cushion
and seatback while tightening the webbing
of the anchor attachments.
6. Tighten the tether strap according to the manufacturer’s instructions to remove any
slack. 7. After attaching the child restraint, test it be-
fore you place the child in it. Push it from side
to side while holding the child restraint near
the LATCH attachment path. The child re-
straint should not move more than 1 inch (25
mm) , from side to side. Try to tug it forward
and check to see if the LATCH attachment
holds the restraint in place. If the restraint is
not secure, tighten the LATCH attachment
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 re-
straints fit in all types of vehicles. 8. Check to make sure the child restraint is
properly secured prior to each use. If the
child restraint is loose, repeat steps 2
through 7.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION USING
THE SEAT BELTS

Refer to all Warnings and Cautions in the “Child
Safety” and “Child Restraint” sections before in-
stalling a child restraint.
Follow these steps to install a forward-facing
child restraint using the vehicle seat belt in the
rear seats or in the front 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, there-
fore, must not be used in the front seat.
2. Position the child restraint on the seat. Al- ways follow the child restraint manufactur-
er’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head re-
straint to obtain the correct child restraint fit.
If the head restraint is removed, store it in a
secure place. Be sure to reinstall the
head restraint when the child restraint
is removed. See “Head restraints” in this
section for head restraint adjustment, re-
moval and installation information.
If the seating position does not have an
adjustable head restraint and it is interfering
with the proper child restraint fit, try another
seating position or a different child restraint. 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 in-
structions 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 “In-
stalling top tether strap” in this section. 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.

8. After attaching the child restraint, test it be-fore 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 frontpassenger seat, place the ignition switch in
the ON position. The front passenger air bag
status light

INSTALLING TOP TETHER STRAP
First, secure the child restraint with the LATCH
lower anchors (rear outboard seat positions only)
or the seat belt, as applicable.1. Flip up the anchor cover
1from the anchor
point which is located directly behind the
child seat.
2. Position the top tether strap over the top of the seatback
2.
3. Secure the tether strap to the tether anchor point on the rear parcel shelf
3. 4. Refer to the appropriate child restraint in-
stallation procedure steps in this section
before tightening the tether strap.
To remove or reinstall the tether anchor covers,
see “Upper tether anchor/key cylinder covers” in
the “Maintenance and do-it-yourself” section of
this manual.
If you have any questions when installing a
top tether strap, consult your NISSAN
dealer for details.
BOOSTER SEATS
Precautions on booster seats

3. The booster seat should be positioned onthe vehicle seat so that it is stable.
If necessary, adjust or remove the head re-
straint to obtain the correct booster seat fit. If
the head restraint is removed, store it in a
secure place. Be sure to reinstall the
head restraint when the booster seat is
removed. See “Head restraints” in this sec-
tion for head restraint adjustment, removal
and installation information. If the seating position does not have an
adjustable head restraint 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 manufacturer’s in-
structions for adjusting the seat belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up extra slack.
Be sure the shoulder belt is positioned
across the top, middle portion 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 instruc- tions for properly fastening a seat belt
shown in “Three-point type seat belt with
retractor” earlier in this section. 7. If the booster seat is installed in the front
passenger seat, place the ignition switch in
the ON position. The front passenger air bag
status light

wearing the seat belt properly for the most effec-
tive protection by the seat belt and supplemental
air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor is designed to operate as
described above to turn the front passenger air
bag OFF for specified child restraints as required
by the regulations. Failing to properly secure
child restraints and to use the ALR mode (child
restraint mode) may allow the restraint to tip or
move in an accident or sudden stop. This can
also result in the passenger air bag inflating in a
crash instead of being OFF. See “Child re-
straints” earlier in this section for proper use and
installation.
If the front passenger seat is not occupied, the
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 being detected by the occupant clas-
sification 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 passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the passen-
ger air bag status light is illuminated (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.
If a child restraint must be used in the front seat,
the 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 air
bag status light is not illuminated (indicating 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 air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF) . Your NISSAN dealer can check that the
system is OFF by using a special tool. However,until you have confirmed with your dealer that
your air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The air bag system and 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 air bag status light will
remain off.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light

Your vehicle may have two types of security sys-
tems:● 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 lid when the system is armed. It is not,
however, a motion detection type system that
activates when a vehicle is moved or when a
vibration occurs.
The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your Intelligent Key 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 protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft 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 vehicle.
3. Close all doors, hood and trunk. Lock all doors. The doors can be locked with the
Intelligent Key, door handle request switch
(if so equipped) , power door lock switch or
mechanical key.
4. Confirm that the security indicator light comes on. The security light stays on for
about 30 seconds. The vehicle security sys-
tem is now pre-armed. After about 30 sec- onds the vehicle security system automati-
cally shifts into the armed phase. The
security light begins to flash once every 3
seconds. If, during the 30-second pre-arm
time period, the driver’s door is unlocked by
the key or the keyfob, or the ignition switch is
placed in the ACC or ON position, the sys-
tem will not arm.
● Even when the driver and/or passen-
gers are in the vehicle, the system will
activate with all the doors, hood and
trunk lid 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 after ap-
proximately 50 seconds. 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

The HomeLinkUniversal Transceiver provides a
convenient way to consolidate the functions of up
to three individual hand-held transmitters into
one built-in device.
HomeLink Universal Transceiver:
● Will operate most Radio Frequency (RF)
devices such as garage doors, gates, home
and office lighting, entry door locks and se-
curity systems.
● Is powered by your vehicle’s battery. No
separate batteries are required. If the vehi-
cle’s battery is discharged or is discon-
nected, HomeLink will retain all program-
ming.
Once the HomeLink Universal Transceiver
is programmed, retain the original trans-
mitter for future programming procedures
(Example: new vehicle purchases) . Upon
sale of the vehicle, the programmed
HomeLink Universal Transceiver buttons
should be erased for security purposes. For
additional information, refer to “Program-
ming HomeLink” later in this section.
