brake and turn the ignition key to the ON
position without starting the engine. The
following lights come on:
,or,,,
The following lights come on briefly and
then go off:
or,,
If any light fails to come on, it may
indicate a burned-out bulb or an opencircuit in the electrical system. Have the
system repaired promptly.
WARNING LIGHTS
Engine oil pressure warning
light
This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop
the engineimmediatelyand call an autho-
rized NISSAN dealer.
The oil pressure warning light is notdesigned to indicate a low oil level. Use
the dipstick to check the oil level.See
``Engine oil'' in the ``Do-it-yourself'' section.
CAUTION
Running the engine with the oil pressure
warning light on could cause serious
damage to the engine almost immedi-
ately. Turn off the engine as soon as it is
safe to do so.

WARNING
cGasoline is extremely flammable and
highly explosive under certain con-
ditions. You could be burned or se-
riously injured if it is misused or
mishandled. Always stop the engine
and do not smoke or allow open
flames or sparks near the vehicle
when refueling.
c
Fuel may be under pressure. Turn the
cap one-half turn, and wait for any
``hissing'' sound to stop to prevent
fuel from spraying out and possible
personal injury. Then remove the cap.
cDo not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, result-
ing in fuel spray and possibly fire.
cUse only an original equipment type
fuel filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury.
cNever pour fuel into the throttle body
to attempt to start your vehicle.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.
cTighten until the fuel filler cap clicks.
Failure to tighten the fuel filler cap
properly may cause the
mal-
function indicator lamp (MIL) to illu-
minate. If the
lamp illuminates
because the fuel filler cap is loose or
missing, tighten or install the cap
and continue to drive the vehicle.
The
lamp should turn off after
a few driving trips. If thelamp
does not turn off after a few driving
trips, have the vehicle inspected by
an authorized NISSAN dealer.
cFor additional information, see the
ªMalfunction indicator lamp (MIL)''
in the ªInstrument and controlsº
section earlier in this manual.Put the fuel filler cap on the cap holder while
refueling.WPD0050

During the first 1,000 miles (1,600 km),
follow these recommendations for the future
reliability and economy of your new vehicle.
Failure to follow these recommendations
may result in vehicle damage or shortened
engine life.
cDo not drive over the legal speed limit
and do not run the engine over 4,000
rpm. Avoid driving for long periods at
constant speed, either fast or slow.
cDo not accelerate at full throttle in any
gear.
cAvoid quick starts.
cAvoid hard braking as much as possible.
cDo not tow a trailer for the first 500 miles
(800 km).cAccelerate slowly and smoothly. Main-
tain cruising speeds with a constant ac-
celerator position.
cDrive at moderate speeds on the high-
way. Driving at high speed lowers fuel
economy.
cAvoid unnecessary stopping and brak-
ing. Maintain a safe distance behind
other vehicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.cKeep your engine tuned up.
cFollow the recommended periodic main-
tenance schedule.
cKeep the tires inflated at the correct
pressure. Low tire pressure increases
tire wear and wastes fuel.
cKeep the front wheels in correct align-
ment. Improper alignment increases tire
wear and lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only
when necessary.
cWhen cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.

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.

3. Remove the three nuts and one bolt
mounting the headlamp assembly (see
above illustration).
4. Pull the headlamp assembly evenly away
from the front of the vehicle to access the
bulb sockets.5. Disconnect the harness connector from
the back side of the bulb socket (see
above illustration).
6. Turn the bulb retaining ring counter-
clockwise until it is free from the head-
lamp assembly and then remove it.
7. Remove the bulb by pulling it straight out
of the lamp assembly. Do not shake the
bulb when removing it.
8. Follow the instructions in reverse order to
install new bulb.
Headlamp mounting nuts and bolt
torque: 36 to 47 in-lb (4.1 to 5.3 Nzm)
Adjusting the headlight aim
Before performing aiming adjustment, make
sure of the following:
a. Use an aiming wall screen.
b. Keep all of the tires inflated to the correct
pressure.
c. Place the vehicle and screen on level
ground.
d. See that the vehicle is unloaded (except
for full levels of coolant, engine oil and
fuel, and that the spare tire, jack, and
tools are stored). Have the driver or an
equivalent weight placed in the driver's
seat.
Low beam
1. Open the hood. Turn headlamp low
beam on.
2. Adjust the vertical aim by turning the
adjusting screw.
cCover the opposite lamp and ensure the
fog lamps (if so equipped) are turned off.
cAdjust beam pattern until cutoff line is
positioned at the same height off ground
as bulb center (on H-line).
