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 run 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. .
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.

SEAT BELT WARNING LIGHT
AND CHIME
The driver and front passenger seats are
equipped with an enhanced seat belt remin-
der function. If your vehicle is equipped with
an enhanced seat belt reminder function, a
visual and audible alert will operate if a
driver or front passenger seat belt is un-
buckled at speeds of approximately 10 MPH
(15 km/h) or more under the following
conditions:
.If the driver seat belt is not fastened.
. The front passenger’s seat belt is not
fastened and the seat is occupied by a
passenger for 7 seconds after the igni- tion switch is placed in the ON position.
. The front passenger’s seat belt is not
fastened and objects or external force on
the passenger seat change the seat belt
reminder classification to “occupied”.
The seat belt warning light will flash under
the conditions shown above until the neces-
sary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 95 seconds or until one of the
following conditions is met:
. The unbuckled front passenger’s seat
belt is securely fastened.
. The seat belt reminder function in the
front passenger seat no longer detects
that the front passenger seat is occu-
pied.
. The ignition switch is turned off.
The below situations could result in the seat
belt warning light being illuminated and the
chime sounding, even with no occupant
present in the passenger seat:
. Heavy objects placed on the seat.
. Someone pushing or pulling on the front
passenger seat.
. An object placed under the front passen-
ger seat.
. An object placed between the seat
cushion and center console or between
the seat cushion and the door.

.An object hanging on the seat or placed
in the seatback pocket (If so equipped).
. A child restraint or other object pressing
against the rear of the seatback.
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.
PRE-CRASH SEAT BELTS WITH
COMFORT FUNCTION (front
seats) (if so equipped)
The pre-crash seat belt tightens the seat belt
with a motor to help restrain front seat
occupants. This helps reduce the risk of
injury in a collision.
The motor retracts the seat belt under the
following emergency conditions: .
During emergency braking.
. During sudden steering maneuvers.
. Activation of the Forward Emergency
Braking (FEB) system. (See “Forward
Emergency Braking (FEB)” (P.5-102).)
The pre-crash seat belt will not be active
when:
. The seat belt is not fastened.
. The vehicle speed is under 10 MPH (15
km/h) during emergency braking.
. The vehicle speed is under 19 MPH (30
km/h) during sudden steering maneu-
vers.
The pre-crash seat belt will not be active
when the brake pedal is not depressed
except when sudden steering maneuvers
occur or the FEB system activates.
The motor also retracts the seat belt when
the seat belt is fastened or unfastened.
When the seat belt is fastened, the motor
tightens the seat belt for a snug fit. When
the seat belt is unfastened, the motor
retracts the seat belt. If the seat belt is not
fully retracted, the motor retracts the seat
belt when the door is opened.
Always wear your seat belt correctly and sit
upright and well back.
If the motor cannot retract the seat belt
when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat belt system has a malfunction. It is recommended
you have an 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 a few
minutes, the motor normally 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 the system checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.
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
Safety — Seats, seat belts and supplemental restraint system1-15

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.1-22).
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.
