To fasten the seat belt, see “Fastening the
seat belts” (P.1-16).
WARNING
.Do not unfasten the rear center seat belt
connector except when folding down the
rear seat.
. When attaching the rear center seat belt
connector, be certain that the seatbacks
are completely secured in the latched
position and the rear center seat belt
connector is completely secured.
. If the rear center seat belt connector and
the seatbacks are not secured in the
correct position, serious personal injury may result in an accident or sudden
stop.
SSS0294A
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
”(P.1-12).)
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 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
damage on the webbing is found, the
entire seat belt assembly should be
replaced.
Safety —Seats, seat belts and supplemental restraint system1-21

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 sys-
tem (Air bag system) for the front passen-
ger. See“Supplemental restraint system ”
(P.1-42).
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 manu-
facturer’s instructions for installation and
use.
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
restraint with a harness. Refer to the
manufacturer’s instructions for minimum
and maximum weight and height recom-
mendations. INFINITI recommends that
small children be placed in child restraints
that comply with Federal Motor Vehicle
Safety Standards or Canadian Motor Vehi-
cle Safety Standards. You should choose a
child restraint that fits your vehicle and
always follow the manufacturer’s instruc-
tions 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 manufac-
turer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-
facing child restraint, INFINITI recommends
that the child be placed in a commercially
available booster seat to obtain proper
seat belt fit. For a seat belt to fit properly,
the booster seat should raise the child so
that the shoulder belt is properly posi-
tioned across the chest and the top,
middle portion of the shoulder. Theshoulder 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 abdo-
men.
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. Once the child has
grown so the shoulder belt is no longer
on or near the face and neck, and the lap
belt can be positioned properly across the
lower hips or upper thighs, use the seat
belt without the booster seat.
WARNING
Never let a child stand or kneel on any seat
and do not allow a child in the cargo area.
The child could be seriously injured or killed
in a sudden stop or collision.
Safety
—Seats, seat belts and supplemental restraint system1-23

.When the child restraint is not in use,
keep it secured with the LATCH system
or a seat belt. In a sudden stop or
collision, loose objects can injure occu-
pants or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating surface
and buckles before placing a child in the
child restraint.
This vehicle is equipped with a universal
child restraint anchor system, referred to
as the LATCH (Lower Anchors and Tethers
for CHildren) system. Some child restraints
include rigid or webbing-mounted attach-
ments that can be connected to these
anchors.
For details, see “Lower Anchors and
Tethers for CHildren System (LATCH)” (P.1-
26).
If you do not have a LATCH compatible
child restraint, the vehicle seat belts can
be used.
Several manufacturers offer child restraints for infants and small children of various
sizes. When selecting any child restraint,
keep the following points in mind:
.
Choose only a restraint with a label
certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.
. Check the child restraint in your vehicle
to be sure it is compatible with the
vehicle’s seat and seat belt system.
. If the child restraint is compatible with
your vehicle, place your child in the
child restraint and check the various
adjustments to be sure the child
restraint is compatible with your child.
Choose a child restraint that is de-
signed for your child’ s height and
weight. Always follow all recommended
procedures.
All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved child
restraint at all times while the vehicle is
being operated. Canadian law requires the
top tether strap on forward-facing child
restraints be secured to the designated
anchor point on the vehicle.

MIRRORS

maged from wind pressure.If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.

see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
SDI1606
Example
*1Tire size (example: P215/60R16
94H)
1.P: The “P”indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2.Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3.Two-digit number (60): This num-
ber, known as the aspect ratio, gives the tire’s ratio of height to
width.
4.R: The “R”stands for radial.
F: The “F”after “R”indicates Self-
Supporting type run-flat tire.
5.Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6.Two- or three-digit number (94):
This number is the tire’ s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because it
is not required by law.
7.H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.
Maintenance and do-it-yourself8-33

.The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted, radial or run-flat), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models, if
your vehicle was originally equipped
with 4 tires that were the same size
and you are only replacing 2 of the 4
tires, install the new tires on the rear
axle. Placing new tires on the front axle
may cause loss of vehicle control in
some driving conditions and cause an accident and personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” (P.9-
9) of this manual for wheel off-set
dimensions.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
