7-6Appearance and care

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift lever to P
(Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
●

mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
CAUTION
●Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ●
Avoid contact with used engine oil and
coolant. Improperly disposed engine
