Safety
—Seats, seat belts and supplemental restraint system1-11

when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat
belt system has a malfunction. Have your
INFINITI retailer check and repair the
system.
When the seat belt is retracted repeatedly
in a short period of time, the motor may
not be able to retract the seat belt. After 30
seconds, the motor reactivates and retracts
the seat belt. If the seat belt still cannot be
retracted by the motor, the pre-crash seat
belt system has a malfunction. Have your
INFINITI retailer check and repair the
system.
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 danger-
ous. 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 in the
seat with both feet on the floor and
adjust the seat belt properly.
SSS0292
Fastening the seat belts
1. Adjust the seat. (See “Seats ”earlier in
this section.)
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,
Safety —Seats, seat belts and supplemental restraint system1-15

1-16Safety—Seats, seat belts and supplemental restraint system
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 restraints” later in this section.
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 com-
pletely 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 or if you have any question about
seat belt operation, see an INFINITI retailer.

Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
“Precautions on seat belt usage ”earlier in
this section.)
To adjust, push the button
*A, and then
move the shoulder belt anchor to the
desired position, so that the belt passes
over the center of the shoulder. The belt
should be away from your face and neck,
but not falling off of your shoulder. Release
the adjustment button to lock the shoulder
belt anchor into position.
WARNING
. After adjustment, release the adjustment
button and try to move the shoulder belt
anchor up and down to make sure it is
securely fixed in position.
. The shoulder belt anchor height should
be adjusted to the position best for you.
Failure to do so may reduce the effec-
tiveness of the entire restraint system
and increase the chance or severity of
injury in an accident.
SEAT BELT EXTENDERS
If, because of body size or driving position,
it is not possible to properly fit the lap-
shoulder belt and fasten it, an extender
that is compatible with the installed seat
belts is available that can be purchased.
The extender adds approximately 8 in (200
mm) of length and may be used for either
the driver or front passenger seating
position. See an INFINITI retailer for assis-
tance with purchasing an extender if an
extender is required.
WARNING
.Only INFINITI seat belt extenders, made
by the same company which made the
original equipment seat belts, should be
used with the INFINITI seat belts.
. Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use could
result in serious personal injury in the
event of an accident.
. Never use seat belt extenders to install
child restraints. If the child restraint is
not secured properly, the child could be
seriously injured in a collision or a
sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution
recommended for cleaning upholstery
or carpets. Then, wipe with a cloth and
allow the seat belts to dry in the shade.
Do not allow the seat belts to retract
until they are completely dry.
. If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat

4. After attaching the child restraint, test
it before you place the child in it. Push
it from side to side while holding the
child restraint near the LATCH attach-
ment 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 LATCH attach-
ment 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 or try installing
by using the vehicle seat belt (if applicable). Not all child restraints fit
in all types of vehicles.
5. Check to make sure the child restraint is properly secured prior to each use. If
the child restraint is loose, repeat steps
1 through 4.

REAR-FACING CHILD RESTRAINT IN-
STALLATION USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
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
passenger air bag. See “Front passenger air
