2002 NISSAN SENTRA length

WARNING
cAfter 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.
cThe shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may
reduce the effectiveness of the en-
tire 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 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.
cAdults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal in-
jury in the event of an accident.
Never use seat belt extenders to in-
stall child restraints. If the child re-
straint is not serviced properly, the
child could be seriously injured in a
collision or sudden stop.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
cDo not leave children, impaired
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 pos-
sibly fatal injuries to people or ani-
mals.
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
cDo not breathe exhaust gases; they
contain colorless and odorless car-bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death.
cIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows fully open, and have the
vehicle inspected immediately.
cDo not run the engine in closed
spaces such as a garage.
cDo not park the vehicle with the
engine 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 with the
trunk lid open, follow these precau-
tions.
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the
fan control dial to 4 (high) to cir-
culate the air.cIf electrical wiring or other cable
connections 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.

cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with an automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P (Park)
position. If you move the shift selector
lever to the P (Park) position before block-
ing the wheels and applying the parking
brake, transmission damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature coolant rises
to an extremely high temperature when
the air conditioning system is on, turn off
the air conditioner. Coolant heat can be
additionally vented by opening the win-
dows, switching the fan control to high
and setting the temperature control to
the HOT position.
cTrailer towing requires more fuel than
normal circumstances.cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule in the
ªNISSAN Service and Maintenance
Guideº.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
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 thetrailer 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 and do-it-yourself'' section earlier
in this manual.
