Backing up near a projecting
object
The predicted course linesOA(if so
equipped) do not touch the object in the
display. However, the vehicle may hit the
object if it projects over the actual backing
up course.
Backing up behind a projecting
object
The positionOCis shown farther than the
position
OBin the display. However, the po-
sition
OCis actually at the same distance as
the position
OA. The vehicle may hit the object when backing up to the position
OA
if the object projects over the actual back-
ing up course.
HOW TO PARK WITH PREDICTED
COURSE LINES (if so equipped)
WARNING
• If the tires are replaced with different
sized tires, the predicted course lines
may be displayed incorrectly.
• On a snow-covered or slippery road,
there may be a difference between
the predicted course line and the ac-
tual course line.
• If the battery is disconnected or be-
comes discharged, the predicted
course lines may be displayed incor-
rectly. If this occurs, please perform
the following procedures:
– Turn the steering wheel from lock
to lock while the engine is
running.
– Drive the vehicle on a straight road
for more than 5 minutes.
• When the steering wheel is turned
with the ignition switch in the ACC
position, the predicted course lines
may be displayed incorrectly.

WARNING
• The air conditioner cooling function
operates only when the engine is
running.
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Do not use the recirculation mode for
long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
NOTE:
• Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
• When parking, set the heater and air conditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.LHA4783

ture control to the full HOT position. • When the
position is selected, the air
conditioner automatically turns on if the
outside temperature is more than 36°F
(2°C). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance. The recircula-
tion mode cannot be activated in the
position.

position is selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.

mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.
3. Turn the temperature control dial to the desired position.
Operating tips
• Keep the windows closed while the airconditioner is in operation. • Af ter parking in the sun, drive for 2 or 3
minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• The air conditioning system should be operated for approximately 10 minutes at
least once a month. This helps prevent
damage to the system due to lack of lu-
brication.
• A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
• If the engine coolant temperature gauge indicates engine coolant temperature
over the normal range, turn the air condi-
tioner off. For additional information, refer
to “If your vehicle overheats” in the “In case
of emergency” section of this manual.
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.

4-42Monitor, climate, audio, phone and voice recognition systems

• 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.
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 equip-
ment.
