Automatic Transmission fluid
temperature gauge
This gauge indicates the temperature of
the automatic transmission fluid.
CAUTION
• This gauge is not designed to indi-
cate low automatic transmission
fluid level. Use the dipstick to check
the fluid level. For additional infor-
mation, see “Automatic Transmis-
sion Fluid (ATF)” (P. 8-13).
• If the gauge indicates automatic
transmission fluid temperature over
the normal range, stop the vehicle as
soon as safely possible. It is recom-
mended that you have the vehicle
checked by a NISSAN dealer. Contin-
ued operation of the vehicle may se-
riously damage the transmission.
Voltmeter
When the ignition switch is placed in the ON
position, the voltmeter indicates the bat-
tery voltage. When the engine is running, it
indicates the generator voltage.
While cranking the engine, the volts drop
below the normal range. If the range is not
within the normal range (11 – 15 volts) while
the engine is running, it may indicate that
the charging system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Engine oil pressure gauge
The gauge indicates the engine lubrication
system oil pressure while the engine is run-
ning. The bar should be in the middle of the
gauge when the engine is running.
CAUTION
• This gauge is not designed to indi-
cate low engine oil level. Use the dip-
stick to check the oil level. For addi-
tional information, see “Engine oil”
(P. 8-8).
• If the gauge needle does not move
with the proper amount of engine oil,
it is recommended that you have the

2-34Instruments and controls

• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature
are low, the air flow outlet may default to
defroster mode for approximately 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant tempera-
ture warms up, the air flow outlet will
return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when previous climate setting was sys-
tem off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, air flow
outlet will return to previous settings, and
operation will continue normally. To exit,
press any climate control button.
• Keep the windows closed while the air conditioner is in operation. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction.
• When the ignition is placed in the ON po- sition, in some fogging or high cabin
temp conditions, air may flow automati-
cally to the foot outlets for 3 to 7 seconds
to purge the hot air in the system. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, see “Air conditioner system
refrigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The
air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.
