WARNING AND INDICATOR LIGHTS

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.

The illustration shows the seating positions
equipped with head restraint/headrest.
Indicates the seating position is
equipped with a head restraint.
Indicates the seating position is
equipped with a headrest.
+ Indicates the seating position is not
equipped with a head restraint or headrest
(if applicable).
. Your vehicle is equipped with a head
restraint/headrest that may be inte-
grated, adjustable or non-adjustable.
. Adjustable head restraints/headrests
have multiple notches along the stalk to
lock them in a desired adjustment posi-
tion. .
The non-adjustable head restraints/
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.

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.

3. Position the lap belt portionlow 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.1-18).
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

WARNING
.After adjustment, release the adjust-
ment 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 effectiveness 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 ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver
or front passenger seating position. It is
recommended you visit an INFINITI retailer
for assistance with purchasing an extender if
an extender is required.
WARNING
.It is recommended only INFINITI seat
belt extenders, made by the same
company which made the original
equipment seat belts, 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 or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution re-
commended 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 belts
may retract slowly. Wipe the shoulder belt guide with a clean, dry cloth.
. Periodically check to see that the seat
belt and the metal components such as
buckles, tongues, retractors, flexible
wires and anchors work properly. If loose
parts, deterioration, cuts or other da-
mage on the webbing is found, the entire
seat belt assembly should be replaced.

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. If the seat belt can not be
unbuckled or is already unbuckled, re-
lease the child by cutting the seat belt
with a suitable tool (such as a knife or
scissors) to release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available
from many other sources, including doctors,
teachers, government traffic safety offices,
and community organizations. Every child is
different, so be sure to learn the best way to
transport your child.
There are three basic types of child restraint
systems: .
Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year
and less than 20 lbs (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for
children who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle lap/
shoulder belt on a child who can no longer
use a forward-facing child restraint.
WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. See
“Child restraints” (P.1-18). A child restraint may be secured in the
vehicle by using either the LATCH (Lower
Anchor and Tethers for CHildren) system or
with the vehicle seat belt. See “Child re-
straints” (P.1-18) for more information.
INFINITI recommends that all pre-teens and
children be restrained in the rear seat.
Studies show that children are safer when
properly restrained in the rear seat than in
the front seat.
This is especially important because your
vehicle has a supplemental restraint system
(Air bag system) for the front passenger.
See “Supplemental restraint system” (P.1-
37).INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
INFINITI recommends that infants be placed
in child restraints that comply with Federal
Motor Vehicle Safety Standards or Cana-
dian Motor Vehicle Safety Standards. You
should choose a child restraint that fits your
vehicle and always follow the manufac-
turer’s instructions for installation and use.
CHILD SAFETY

SMALL CHILDREN
Children that are over 1 year old and weigh
at least 20 lbs (9 kg) should remain in a rear-
facing child restraint as long as possible up
to the height or weight limit of the child
restraint. Children who outgrow the height
or weight limit of the rear-facing child
restraint and are at least 1 year old should
be secured in a forward-facing child re-
straint with a harness. Refer to the manu-
facturer’s instructions for minimum and
maximum weight and height recommenda-
tions. INFINITI recommends that small chil-
dren be placed in child restraints that comply
with Federal Motor Vehicle Safety Stan-
dards or Canadian Motor Vehicle Safety
Standards. You should choose a child re-
straint that fits your vehicle and always
follow the manufacturer’s instructions for
installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they reach
the maximum height or weight limit allowed
by the child restraint manufacturer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-fa-
cing child restraint, INFINITI recommends
that the child be placed in a commercially
available booster seat to obtain proper seatbelt fit. For a seat belt to fit properly, the
booster seat should raise the child so that
the shoulder belt is properly positioned
across the chest and the top, middle portion
of the shoulder. The shoulder belt should not
cross the neck or face and should not fall off
the shoulder. The lap belt should lie snugly
across the lower hips or upper thighs, not the
abdomen.
A booster seat can only be used in seating
positions that have a three-point type seat
belt. The booster seat should fit the vehicle
seat and have a label certifying that it
complies with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle
Safety Standards.
A booster seat should be used until the child
can pass the seat belt fit test below:
.
Are the child’s back and hips against the
vehicle seatback?
. Is the child able to sit without slouching?
. Do the child’s knees bend easily over the
front edge of the seat with feet flat on
the floor?
. Can the child safely wear the seat belt
(lap belt low and snug across the hips
and shoulder belt across mid-chest and
shoulder)?
. Is the child able to use the properly
adjusted head restraint/headrest? .
Will the child be able to stay in position
for the entire ride?
