2-30Instruments 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 de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature 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 the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) 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. 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 re-
frigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly ” air conditioner 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.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust headrests/head restraints.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter

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 fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• 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.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle. •
Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without
warning, even if the ignition switch is
in the OFF position and the engine is
not running. To avoid injury, always
disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an en-
closed 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 nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• On gasoline engine models, the fuel
filter or fuel lines should be serviced.
It is recommended that you visit a
NISSAN dealer for this service be-
cause the fuel lines are under high
pressure even when the engine is off.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down. •
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 vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-26).

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marks
OB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
OA,re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
fill oil level above H (High) mark
OC.
6. Recheck oil level with the dipstick.
