CHILD SAFETY REAR DOOR LOCK
Child safety locks help prevent the rear doors
from being opened accidentally, especially when
small children are in the vehicle.
The child safety lock levers are located on the
edge of the rear doors.
When the lever is in the lock position, the
door can be opened only from the outside.It is possible to lock/unlock all doors, turn the
interior light on, and activate the panic alarm by
using the keyfob from outside the vehicle.
Be sure to remove the key from the vehicle
before locking the doors.
The keyfob can operate at a distance of approxi-
mately 49 ft (15 m) from the vehicle. The effective
distance depends upon the conditions around
the vehicle.
As many as 4 keyfobs can be used with one
vehicle. For information concerning the purchase
and use of additional keyfobs, contact a NISSAN
dealer.
The keyfob will not function when:
cthe battery is discharged
cthe distance between the vehicle and the
keyfob is over 49 ft (15 m)
CAUTION
Listed below are conditions or occur-
rences which will damage the keyfob:
cDo not allow the keyfob to become wet.
cDo not drop the keyfob.

RADIO
Turn the ignition key to the ACC or ON position
and press the PWR (power)/VOL (volume) 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

fuse opens, the radio memory is canceled. In that
case, reset the desired stations.
Compact disc (CD) player operation
Turn the ignition key to the ACC or ON position,
and carefully insert the compact disc into the slotwith the label side up. The compact disc is auto-
matically pulled into the slot and starts to play.
If the radio is already operating, it automatically
turns off and the compact disc begins to play.
CAUTION
Do not force a compact disc into the CD
insert slot. This could damage the CD
and/or CD changer/player.
CD·C button
When the CD·C button is pushed with a compact
disc loaded and the radio playing, the radio turns
off and the compact disc starts to play.
When this button is pushed while the compact
disc is playing, the compact disc stops playing.
Press the CD·C button to play a compatible
device such as an MP-3 Player when it is plugged
into the AUX in jack.
FF (Fast Forward) , REW
(Rewind) buttons
