Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. For
additional information, refer to “Precau-
tions on seat belt usage” in this section. To
adjust, pull out the adjustment button
1
and move the shoulder belt anchor to the
desired position
2, so the belt passes over
the center of the shoulder. The belt should
be away from your face and neck, but not
falling off your shoulder. Release the ad-
justment button to lock the shoulder belt
anchor into position.
WARNING
∙ Af ter 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 re-
duce 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 for purchase. 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 that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
∙ Only NISSAN seat belt extenders,made by the same company which
made the original equipment seat
belts, should be used with NISSAN
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 in- stall child restraints. If the child re-
straint 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 rec-
ommended 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.

Safety—Seats, seat belts and supplemental restraint system1-19

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
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.
∙ Closely 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
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. ∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
∙ If 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 rec-
ommendation to prevent carbon
monoxide entry into the vehicle. ∙ The 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 involving 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
∙ The exhaust gas and the exhaust sys-tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system
components.
