FRONT-SEAT ACTIVE HEAD RE-
STRAINT
The Active Head Restraint moves forward
utilizing the force that the seatback receives
from the occupant in a rear-end collision.
The movement of the head restraint helps
support the occupant’s head by reducing its
backward movement and helping absorb
some of the forces that may lead to
whiplash-type injuries.
Active Head Restraints are effective for
collisions at low to medium speeds in which
it is said that whiplash injury occurs most.
Active Head Restraints operate only in
certain rear-end collisions. After the colli-

sion, the head restraints return to their
original position.
Adjust the Active Head Restraints properly
as described earlier in this section.PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly
adjusted, and you are sitting upright and well
back in your seat with both feet on the floor,
your chances of being injured or killed in an
accident and/or the severity of injury may be
greatly reduced. INFINITI strongly en-
courages you and all of your passengers to
buckle up every time you drive, even if your
seating position includes a supplemental air
bag.
Most U.S. states and Canadian provinces or
territories specify that seat belts be worn at
all times when a vehicle is being driven.
SEAT BELTS

SSS0134A
WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be properly
restrained in the rear seat and, if
appropriate, in a child restraint.
. The seat belt should be properly
adjusted to a snug fit. Failure to do
so may reduce the effectiveness of
the entire restraint system and in-
crease the chance or severity of injury
in an accident. Serious injury or death
can occur if the seat belt is not worn
properly.
. Always route the shoulder belt over
your shoulder and across your chest.
Never put the belt behind your back,
under your arm or across your neck.
The belt should be away from your
face and neck, but not falling off your
shoulder.
. Position the lap belt as low and snug
as possible AROUND THE HIPS, NOT
THE WAIST. A lap belt worn too high
could increase the risk of internal
injuries in an accident.
. Be sure the seat belt tongue is
securely fastened to the proper
buckle.
Safety — seats, seat belts and supplemental restraint system1-19

1-20Safety — seats, seat belts and supplemental restraint system
.Do not wear the seat belt inside out
or twisted. Doing so may reduce its
effectiveness.
. Do not allow more than one person to
use the same seat belt.
. Never carry more people in the ve-
hicle than there are seat belts.
. If the seat belt warning light glows
continuously while the ignition is
turned ON with all doors closed and
all seat belts fastened, it may indicate
a malfunction in the system. Have the
system checked. It is recommended
you visit an INFINITI retailer for this
service.
. No changes should be made to the
seat belt system. For example, do not
modify the seat belt, add material or
install devices that may change the
seat belt routing or tension. Doing so
may affect the operation of the seat
belt system. Modifying or tampering
with the seat belt system may result
in serious personal injury.
. Once a seat belt pretensioner has
activated, it cannot be reused and
must be replaced together with the
retractor. It is recommended you visit
an INFINITI retailer for this service. .
All seat belt assemblies, including
retractors and attaching hardware,
should be inspected after any colli-
sion. It is recommended you visit an
INFINITI retailer for this service.
INFINITI recommends that all seat
belt assemblies in use during a colli-
sion be replaced unless the collision
was minor and the belts show no
damage and continue to operate
properly. Seat belt assemblies not in
use during a collision should also be
inspected and replaced if either da-
mage or improper operation is noted.
. All child restraints and attaching
hardware should be inspected after
any collision. Always follow the re-
straint manufacturer’s inspection in-
structions and replacement
recommendations. The child re-
straints should be replaced if they
are damaged.

PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be worn
snug, and always position the lap belt as low
as possible around the hips, not the waist,
and place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific re-
commendations.
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts, depending on the injury.
Check with your doctor for specific recom-
mendations.
THREE-POINT TYPE SEAT BELT
WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times.
. Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt and receive serious internal injuries.
. For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat belt properly.

WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child. For the center of the 3rd row
bench seat, the connector tongue
may
also be released. Release the connector

tongue by inserting a suitable tool (such
as a key) into the connector buckle.If
the seat belt cannot be unbuckled or is
already unbuckled, release the child by
cutting the seat belt with a suitable tool
(such as a knife or scissors) to release the
seat belt.
SSS0292
Fastening the seat belts
1. Adjust the seat. (See “Seats” (P.1-3).)
2. Slowly pull the seat belt out of the retractor and insert the tongue into the
buckle until you hear and feel the latch
engage.
.The retractor is designed to lockduring a sudden stop or on impact.
A slow pulling motion permits the
belt to move, and allows you some
freedom of movement in the seat.
.If the seat belt cannot be pulled from its fully retracted position, firmly pull
the belt and release it. Then smoothly
pull the belt out of the retractor.
SSS0290
3. Position the lap belt portion low and
snug on the hips as shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack. Be sure
the shoulder belt is routed over your
shoulder and across your chest.
The three-point type seat belts have two
modes of operation:
. Emergency Locking Retractor (ELR)
. Automatic Locking Retractor (ALR)
The Emergency Locking Retractor (ELR)
mode allows the seat belt to extend and
retract to allow the driver and passengers
some freedom of movement in the seat. The
ELR locks the seat belt when the vehicle
slows down rapidly or during impacts.

The Automatic Locking Retractor (ALR)
mode (child restraint mode) locks the seat
belt for child restraint installation.
When the ALR mode is activated the seat
belt cannot be extended again until the seat
belt tongue is detached from the buckle and
fully retracted. The seat belt returns to the
ELR mode after the seat belt fully retracts.
For additional information, see “Child re-
straints” (P.1-30).
The ALR mode should be used only for child
restraint installation. During normal seat
belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt tension.
WARNING
When fastening the seat belts, be certain
that seatbacks are completely secured in
the latched position. If they are not
completely secured, passengers may be
injured in an accident or sudden stop.
SSS0326
Unfastening the seat belts
To unfasten the seat belt, push the button
on the buckle. The seat belt automatically
retracts.
Checking seat belt operation
Seat belt retractors are designed to lock seat
belt movement by two separate methods:
.When the belt is pulled quickly from the
retractor.
. When the vehicle slows down rapidly.
To increase your confidence in the seat belts,
check the operation as follows:
. Grasp the shoulder belt and pull forward
quickly. The retractor should lock and restrict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended you visit an INFINITI retailer for this
service, or to learn more about seat belt
operation.
