8-2Do-it-yourself
When performing any inspection or main-
tenance 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 sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
For manual transmission models,
move the shift lever to N (Neutral).
For automatic transmission mod-
els, move the shift lever to P
(Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position. .
If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed 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 necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid injury, always disconnect the ne-
gative battery cable before work-
ing near the fan.
. Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
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 direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-26).)

FUEL INFORMATION:
VQ37VHR engine
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-
Knock Index) number (Research octane
number 96).
If unleaded premium gasoline is not
available, unleaded regular gasoline with
an octane rating of at least 87 AKI
number (Research octane number 91)
may be temporarily used, but only under
the following precautions:
.Have the fuel tank filled only partially
with unleaded regular gasoline, and fill
up with unleaded premium gasoline
as soon as possible.
. Avoid full throttle driving and abrupt
acceleration.
Use unleaded premium gasoline for
maximum vehicle performance.
CAUTION
. Using a fuel other than that spe-
cified could adversely affect the
emission control systems, and
may also affect warranty cover-
age. .
Under no circumstances should a
leaded gasoline be used, since
this will damage the three way
catalyst.
. Do not use a fuel containing more
than 15% ethanol in your vehicle.
Your vehicle is not designed to
run on a fuel containing more
than 15% ethanol. Using a fuel
containing more than 15% etha-
nol in a vehicle not specifically
designed for a fuel containing
more than 15% ethanol can ad-
versely affect the emission con-
trol devices and systems of the
vehicle. Damage caused by such
fuel is not covered by the NISSAN
new vehicle limited warranty.
. U.S. government regulations re-
quire ethanol dispensing pumps
to be identified by a small,
square, orange and black label
with the common abbreviation or
the appropriate percentage for
that region.
For additional information, see “Capaci-
ties and recommended fluids/lubricants”
(P.10-2).
ENGINE OIL RECOMMENDATION:
See “Capacities and recommended fluids/
lubricants” (P.10-2) for engine oil and oil
filter recommendation.
COLD TIRE PRESSURES:
The label is typically located on the driver
side center pillar or on the driver’s door.
For additional information, see “Wheels
and tires” (P.8-26).
NEW VEHICLE BREAK-IN PROCE-
DURES RECOMMENDATION:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the recommendations
outlined in the “Break-in schedule” (P.5-
24) of this Owner’s Manual. Follow these
recommendations for the future reliability
and economy of your new vehicle.
