WARNING
Head restraints/headrests supplement
the other vehicle safety systems. They
may provide additional protection
against injury in certain rear end colli-
sions. Adjustable head restraints/head-
rests must be adjusted properly, as
specified in this section. Check the
adjustment after someone else uses the
seat. Do not attach anything to the head
restraint/headrest stalks or remove the
head restraint/headrest. Do not use the
seat if the head restraint/headrest has
been removed. If the head restraint/
headrest was removed, reinstall and
properly adjust the head restraint/
headrest before an occupant uses the
seating position. Failure to follow these
instructions can reduce the effectiveness
of the head restraints/headrests. This
may increase the risk of serious injury or
death in a collision.

have multiple notches along the stalk to
lock them in a desired adjustment posi-
tion. .

headrests have a single locking notch to
secure them to the seat frame.
. Proper Adjustment:
— For the adjustable type, align the head restraint/headrest so the center of
your ear is approximately level with
the center of the head restraint/
headrest.
— If your ear position is still higher than the recommended alignment, place
the head restraint/headrest at the
highest position.
. If the head restraint/headrest has been
removed, ensure that it is reinstalled and
locked in place before riding in that
designated seating position.

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.

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.
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.5-104).)
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.
