Instruments and controls2-47

• 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 op-
eration. • 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, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly ” air conditioning system.

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 and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently 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 head restraints/ headrests.
• 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 placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.

11.ECO Mode
• The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable Trans-
mission (if so equipped) operation au-
tomatically to avoid rapid
acceleration. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in
the “Technical and consumer informa-
tion” section of this manual.

WAXING
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove
built-up wax residue and to avoid a weath-
ered appearance before re-applying wax.
It is recommended that you visit a NISSAN
dealer to assist you in choosing the proper
product.
• Wax your vehicle only af ter a thoroughwashing. Follow the instructions supplied
with the wax.
• Do not use a wax containing any abra- sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint fin-
ish may dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the surface of the paint to avoid last-
ing damage or staining. Special cleaning
products are available at a NISSAN dealer
or any automotive accessory store. It is
recommended that you visit a NISSAN
dealer for these products.
UNDERBODY
In areas where road salt is used in winter, it
is necessary to clean the underbody regu-
larly in order to prevent dirt and salt from
building up and causing the acceleration of
corrosion on the underbody and suspen-
sion. Before the winter period and again in
the spring, the underseal must be checked
and, if necessary, re-treated.
GLASS
When cleaning the rear window, it may be
easier to clean if the inside high-mounted
stop light is removed first.
Be careful when removing the high-
mounted stop light to reduce the risk of
damaging the high-mounted stop light
wires.
To remove the high-mounted stop light:
1Push toward rear of vehicle.

WAI0005

Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer's recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.CAUTION
• Never use benzine, thinner or any
similar material.
• Small dirt particles can be abrasive
and damaging to leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes, pol-
ishes, oils, cleaning fluids, solvents,
detergents or ammonia-based
cleaners as they may damage the
leather's natural finish.
• Never use fabric protectors unless
recommended by the manufacturer.
• Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following precau-
tions:
• Hanging-type air fresheners can cause permanent discoloration when they con-
tact vehicle interior surfaces. Place the air
freshener in a location that allows it to
hang free and not contact an interior sur-
face. • Liquid-type air fresheners typically clip on
the vents. These products can cause im-
mediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufactur-
er's instructions before using the air fresh-
eners.
POWER MOONROOF (if so
equipped)
The sunshade is made from a tricot mate-
rial.

•Only touch the base when handling
the bulb. Never touch the glass enve-
lope. Touching the glass could sig-
nificantly affect bulb life and/or
headlight performance.
• High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
• Use the same number and wattage
as shown in the chart.
WARNING
Do not touch bulb by hand while it is lit
or right af ter being turned off. Burning
may result.
CAUTION
• Do not touch glass surface of the bulb
with bare hands or allow oil or grease to
get on it to prevent damage to bulb.
• Do not leave the bulb out of the lamp
reflector for a long time because dust,
moisture, smoke, etc. may affect the
performance of the lamp.
• Fog may temporarily form inside the
lens of the exterior lights in the rain or in a car wash. A temperature difference
between the inside and the outside of
the lens causes the fog. This is not a
malfunction. If large drops of water col-
lect inside the lens, it is recommended
that you visit a NISSAN dealer for ser-
vicing.
