Installing the spare tire
The spare tire is designed for emergency
use. See specific instructions under the
heading ``Wheels and tires'' in the ``Do-
it-yourself'' section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and install
the wheel nuts finger-tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly until they are
tight.4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
cIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
cDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
cRetighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
As soon as possible, tighten the wheel
nuts to the specified torque with a torque
wrench.
Wheel nut tightening torque:
72 to 86 ft-lb
(98 to 117 Nzm)Adjust tire pressure to the COLD pres-
sure.
COLD pressure: After vehicle has been
parked for three hours or more or driven
less than 1 mile (1.6 km).COLD tire pressures are shown on the tire
placard affixed to the driver's door, center
pillar.
5. With the spare tire installed on the ve-
hicle, place the damaged tire in the spare
tire storage area. Put the jack rod and
wheel nut wrench in the tool bag and

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to (N) Neutral. For an automatic
transmission models, move the shift
selector lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cYour vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.c
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.
cIt is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
cAlways wear eye protection when-
ever you work on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
cNever 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.
c
Keep smoking materials, flame and
sparks away from the fuel tank and
battery.cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by an authorized NISSAN
dealer because the fuel lines are un-
der high pressure even when the en-
gine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.
cNever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition is in the ON
position.
cNever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition is in the ON position.
c
Avoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of ve-
hicle fluid.
