When the
orposition is selected,
the air conditioner automatically turns on (how-
ever, the indicator light will not illuminate) . In this
position, the A/C cannot be turned off. When the
air flow control is turned to any position other
than
orthe A/C light will illuminate
(the A/C will continue operating) and can be
turned off using the A/C button. This dehumidi-
fies the air which helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passenger com-
partment to further improve the defogging perfor-
mance.4. Turn the temperature control dial to the de-
sired position.
Operating tips
cKeep the windows and sunroof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
cThe air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cA 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.
cIf the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

RADIO
Turn the ignition key to the ACC or ON position
and press the POWER/VOLUME control knob to
turn the radio on. If you listen to the radio with the
engine not running, the key should be turned to
the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area, and do not indicate any malfunction
in your NISSAN radio system.Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 – 30
miles (40 – 48 km) , with monaural (single chan-
nel) FM having slightly more range than stereo
FM. External influences may sometimes interfere
with FM station reception even if the FM station is
within 25 miles (40 km) . The strength of the FM
signal is directly related to the distance between
the transmitter and receiver. FM signals follow a
line-of-sight path, exhibiting many of the same
characteristics as light. For example, they will
reflect off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.
Static and flutter: During signal interference from
buildings, large hills or due to antenna position
(usually in conjunction with increased distance
from the station transmitter) static or flutter can
be heard. This can be reduced by adjusting the
treble control to reduce treble response.Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject to interference as they travel from transmitter
to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.
SATELLITE RADIO RECEPTION (if so
equipped)
When the satellite radio is first installed or the
battery has been replaced, the satellite radio may
not work properly. This is not a malfunction. Wait
more than 10 minutes with satellite radio ON and

matically turned off.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, the CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction indicator light
(MIL)” in the “Instrument and controls” sec-
tion. This will occur even if all electrical
circuits are functioning properly. In this
case, turn the ignition switch to the OFF
position and wait for 10 seconds. Then turn
the switch back to the ON position. The
vehicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially care-
ful when driving. If necessary, pull to the
side of the road at a safe place and allow
the transmission to return to normal op-
eration, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
cDo not downshift abruptly on slippery
roads. This may cause a loss of control.
cDo not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
CAUTION
cDo not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
cFully depress the clutch pedal before
shifting to help prevent transmission
damage.
cStop your vehicle completely before
shifting into R (Reverse) .
