If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the
parking brake. Shift the manual transmis-
sion into Reverse (R) (automatic trans-
mission in P).
WARNING
The transfer control lever must
be in the 2H, 4H or 4L position.
Never place it in the N position. Other-
wise, the vehicle could roll unexpect-
edly even if the manual transmission is
in gear.
4. Turn off the engine.
WARNING
cMake sure that the parking brake is
securely applied and the manual
transmission is shifted into Reverse
(R) (automatic transmission in P).
cNever change tires when the vehicle
is on a slope, ice or a slippery area.
This is dangerous.
cNever change tires if oncoming traf-
fic is close to your vehicle. Wait for
professional road assistance.
cRaise the hood to warn other traffic
and to signal professional road as-
sistance personnel that you require
assistance.
cHave all passengers get out of the
vehicle and stand in a safe place
away from traffic and clear of the
vehicle.
Blocking wheels
Place suitable blocks at both the front and
back of the wheel diagonally opposite the
flat tire to prevent the vehicle from rolling
when it is jacked up.
WARNING
Be sure to block the wheel as the ve-
hicle may move and could cause per-
sonal injury.

Installing wheel
The spare tire is designed for emergency
use. See specific instructions under the
heading ``Wheels and tires'' in the ``Do-
it-yourself operations'' section.
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten
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.
CAUTION
cAs soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
cWheel nut tightening torque:
87 to 108 ft-lb (118 to 147 Nzm)
cThe wheel nuts must be kept tight-
ened to specifications at all times. It
is recommended that wheel nuts be
tightened to specification at each
lubrication interval.
cAdjust tire pressure to the COLD
pressure.
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 glove box lid.
cRetighten the wheel nuts when thevehicle has been run for 600 miles
(1,000 km).
5. Securely store the flat tire and jacking
equipment in the vehicle.WARNING
cAlways make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an
accident or sudden stop.
cThe spare tire is designed for emer-
gency use. See specific instructions
under the heading ``Wheels and
tires'' in the ``Do-it-yourself opera-
tions'' section.

on the ground:
Turn the ignition key to the OFF
position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
place the ignition key in the LOCK
position. This will result in damage
to the steering lock mechanism.
cWhen towing with the rear wheels on
the ground, release the parking
brake and move the gearshift lever
to the Neutral position (N position).
cOn automatic transmission models,
to move the shift lever to Neutral (N
position), turn the ignition key to the
ACC position. After moving the shift
lever to neutral (N position), be sure
to turn the ignition key to the OFF
position.
cFor 4-wheel drive model:
Set the free-running hubs to the free
position (See ``
Auto-lock free-
running hubsº or ``Manual-lock
free-running hubsº as appropriate inthe ``Starting and driving'' section).
Move the transfer case shift lever into
the 2H position and the transmission
shift lever into the Neutral (N) position.
cAttach safety chains for all towing.2-WHEEL DRIVE MODELS

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.
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the shift lever to P (Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cIf 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 remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.cIf you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cNever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition is
on.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
cFailure to follow these or other com-
mon sense guidelines may lead to
serious injury or vehicle damage.
cImproperly disposed motor oil and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to localregulations for disposal of vehicle
fluid. Avoid contact with used motor
oil.
This ``Do-it-yourself operations'' section
gives instructions regarding only those
items which are relatively easy for an owner
to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by your NISSAN dealer.
