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 is
available which is compatible with the in-
stalled seat belts. The extender adds ap-
proximately 8 inches (200 mm) of length
and may be used for either the driver or front
passenger seating position. See an autho-
rized NISSAN dealer for assistance if the
extender is required.
WARNING
cOnly NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with NISSAN
seat belts.
cPersons 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.
SEAT BELT MAINTENANCE
cTo clean the seat belt webbings,apply
a mild soap solution or any solution
recommended for cleaning upholstery or
carpet. 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.
cIf dirt builds up in the shoulder belt
guideof the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der belt guide with a clean, dry cloth.
c
Periodically check to see that the seat
belt and 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.
WARNING
cInfants and small children should
always be placed in an appropriate
child restraint while riding in the ve-
hicle. Failure to use a child restraint
can result in serious injury or death.
cInfants and small children should
never be carried on your lap. It is not
possible for even the strongest adult
to resist the forces of a severe acci-
dent. The child could be crushed
between the adult and parts of the
vehicle. Also, do not put the same
seat belt around both your child and
yourself.
c
Never install a rear-facing child re-
straint in the front seat. An inflating air
bag could seriously injure or kill your
child. A rear facing child restraint
must be used only in the rear seat.
cNISSAN recommends that the child
restraint system be installed in the
rear seat. According to accident sta-
tistics, children are safer when prop-
erly restrained in the rear seat than
in the front seat.

celed.
TOP STRAP CHILD RESTRAINT
If your child restraint has a top strap, it must
be secured to the provided anchor point.
Anchor bracket hardware must be installed.
The top strap anchor bracket hardware is
available through an authorized NISSAN
dealer.
U.S. Part #88894-89900

Secure the child restraint with the center lap
belt or the lap portion of the outboard Three-
point belt and latch the top strap hook onto
the anchor bracket.To install the anchor bracket, a metric bolt of
the dimensions listed below must be used.
Bolt diameter: 8.0 mm
Bolt length: at least 1.18 in (30 mm)
Thread pitch: 1.25 mm
Secure the top strap to the attaching bolt
which provides the straightest installation of
the top strap.
WARNING
Child restraint anchor points are de-
signed to withstand only those loads
imposed by correctly fitted child re-
straints. Under no circumstances are
they to be used for adult seat belts or
harnesses.

directions to play the other side when the
first side is complete. At this time, the mov-
ing digital squares illuminate on the left side
of the display window.
Precautions on cassette player op-
eration
cTo maintain good quality sound, NIS-
SAN recommends using cassette
tapes of 60 minutes or shorter in
length.
cCassette tapes should be removed
from the player when not in use. Store
cassettes in their protective cases
and away from direct sunlight, heat,
dust, moisture and magnetic sources.
cDirect sunlight can cause the cassette
to become deformed. The use of de-
formed cassettes may cause the cas-
sette to jam in the player.
cDo not use cassettes with labels
which are peeling and loose. If used,
the label could jam in the player.
c
If a cassette has loose tape, insert a
pencil through one of the cassette
hubs and rewind the tape firmly around
the hubs. Loose tape may cause tape
jamming and wavering sound quality.
cOver a period of time, the playback
head, capstan and pinch roller may
collect a tape coating residue as thetape is played. This residue accumu-
lation can cause weak or wavering
sound, and should be removed peri-
odically with a head cleaning tape. If
the residue is not removed periodi-
cally, the player may need to be dis-
assembled for cleaning.

WARNING
cDo not leave children, unreliable
adults, or pets alone in your vehicle.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
cClosely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
trunk closed, when not in use, and
prevent children's access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous.It can cause unconsciousness
or death.
c
If you suspect that exhaust fumes areentering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
cDo not run the engine in a closed
space such as a garage.
cDo not park the vehicle with the en-
gine running for any extended length
of time.
cKeep the trunk lid closed while driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive in this
manner for some reason, take the
following steps:
1. Open all the windows.
2. Set the air recirculation button (if
so equipped) off and the fan con-
trol dial to four (high) to circulate
the air.
3.
Be sure the rear seats are secured
and latched in the upright position.
cIf electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle.cThe exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.
d.You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYST
The three way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
c
The exhaust gas and the exhaust sys-
tem are very hot. Keep people or flam-
mable materials away from the ex-
haust pipe.
cDo not stop or park the vehicle over
flammable materials such as dry

cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently. For
additional information see the ``Mainte-
nance'' section earlier in this manual.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent a tire's ability to stop on wet pavement
as measured under controlled conditions,
on specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight-ahead
braking traction tests, and does notin-
clude acceleration cornering, hydro-
planing, or peak traction characteris-
tics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
