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.

authorized NISSAN dealer. Local service
operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent
accidental damage to your vehicle, NISSAN
recommends having a service operator tow
your vehicle. It is advisable to have the
service operator carefully read the following
precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it
has been lifted by a tow truck.

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
Scheduled maintenance
For your convenience, both required and
optional scheduled maintenance items are
described and listed in your ``NISSAN Ser-
vice and Maintenance Guide.'' You must
refer to that guide to ensure that necessary
maintenance is performed on your Nissan
at regular intervals.
General maintenance
General maintenance includes those items
which should be checked during normalday-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
Performing general maintenance checks re-
quire minimal mechanical skill and only a
few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who and are kept up-to-date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehicles
beforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economic way.
