FUEL GAUGE
The gauge indicates theapproximate
fuel level in the tank.
The gauge may move slightly during
braking, turning, acceleration, or going
up or down hills.
The gauge needle returns to 0 (Empty)
after the ignition switch is placed in the
OFF position.
Refill the fuel tank before the gauge
registers “0” (Empty).
The low fuel warning
appears on the
vehicle information display when the fuel
tank is getting low. Refuel as soon as it is
convenient, preferably before the gauge reaches “0”. There will be a small reserve
of fuel in the tank when the fuel gauge
needle reaches “0”.

ENGINE OIL PRESSURE GAUGE
The gauge indicates the engine lubrica-
tion system oil pressure while the engine
is running. When the engine speed is high,
the engine oil pressure is also high. When
it is low, the gauge indicates the low (L) oil
pressure.
The engine oil pressure is normal when
the gauge points within the zone
shown in the illustration.
CAUTION
.This gauge is not designed to
indicate low engine oil level. Use

the dipstick to check the oil level.
(See “Engine oil” (P.8-6).)
. If the gauge does not move with
the proper amount of engine oil,
have the vehicle checked. It is
recommended you visit a NISSAN
dealer for this service. Continued
vehicle operation in such a con-
dition could cause serious da-
mage to the engine.

VOLTMETER
When the ignition switch is placed in the
ON position, the volt meter indicates the
battery voltage. When the engine is run-
ning, it indicates the generator voltage.
While cranking the engine, the volt drop
below the normal range
. If the gauge is
not in the normal range (10.5 to 15.5 volt)
while the engine is running, it may
indicate that the charging system is not
functioning properly. Have the system
checked. It is recommended you visit a
NISSAN dealer for this service.

Low hydraulic pressure warning indica-
tor:
If the brake warning light illuminates
when the engine is running, or while
driving with the parking brake is released,
check the brake fluid level. If the brake
fluid level is sufficient, it may indicate low
hydraulic pressure in the brake booster. It
is recommended that you have the brake
system checked by a NISSAN dealer
promptly.
Anti-lock Braking System (ABS) warning
indicator:
When the parking brake is released and
the brake fluid level is sufficient, if both
the brake warning light and the Anti-lock

RAIN-SENSING AUTO WIPER SYS-
TEM (if so equipped)
The rain-sensing auto wiper system can
automatically turn on the wipers and
adjust the wiper speed depending on
the rainfall and the vehicle speed by using
the rain sensor located on the upper part
of the windshield.
To set the rain-sensing auto wiper sys-
tem, push the lever down to the AUTO
position
. The wiper will sweep once
while the ignition switch is in the ON
position.
The rain sensor sensitivity level can be
adjusted by turning the knob toward the
front
(High) or toward the rear(Low). .
High — High sensitive operation
. Low — Low sensitive operation
To turn the rain-sensing auto wiper
system off, push up the lever to the OFF
position, or pull down the lever to the LO
or HI position.
CAUTION
Do not touch the rain sensor and
around it when the wiper switch is in
the AUTO position and the ignition
switch is in the ON position. The
wipers may operate unexpectedly
and cause to an injury or may da-
mage a wiper.
. The rain-sensing auto wipers are
intended for use during rain. If the
switch is left in the AUTO position,
the wipers may operate unexpect-
edly when dirt, fingerprints, oil film
or insects are stuck on or around the
sensor. The wipers may also operate
when exhaust gas or moisture affect
the rain sensor.
. The rain-sensing auto wipers may
not operate if rain does not hit the
rain sensor even if it is raining.
. When the windshield glass is coated
with water repellent, the speed of the rain-sensing auto wipers may be
higher even though the amount of
the rainfall is small.
. Be sure to turn off the rain-sensing
auto wiper system when you use a
car wash.
. Using genuine wiper blades is re-
commended for proper operation of
the rain-sensing auto wiper system.

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.
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.10-40).)
