2018 NISSAN SENTRA battery

CAUTION
∙ Be sure to carry the Intelligent Keywith you when operating the vehicle.
∙ Never leave the Intelligent Key in the vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key system trans-
mits weak radio waves. Environmental
conditions may interfere with the opera-
tion of the Intelligent Key system under the
following operating conditions: ∙ When operating near a location where strong radio waves are transmitted,
such as a TV tower, power station and
broadcasting station.
∙ When in possession of wireless equip- ment, such as a cellular telephone,
transceiver or a CB radio.
∙ When the Intelligent Key is in contact with or covered by metallic materials.
∙ When any type of radio wave remote control is used nearby.
∙ When the Intelligent Key is placed near an electric appliance such as a personal
computer. ∙ When the vehicle is parked near a park-
ing meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, the
Intelligent Key system warning light (
)
will blink green for about 30 seconds af ter
the ignition switch is placed in the ON po-
sition.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For information regarding replacement of
a battery, refer to “Battery replacement” in
the “Do-it-yourself ” section of this manual.
As many as four Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of additional Intelligent Keys, it is recom-
mended that you visit a NISSAN dealer.

area and do not indicate any malfunction
in your NISSAN radio system.
Reception conditions will constantly
change because of vehicle movement.
Buildings, terrain, signal distance and inter-
ference from other vehicles can work
against ideal reception. Described below
are some of the factors that can affect your
radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to
come from the audio system speakers.
Storing the device in a different location
may reduce or eliminate the noise.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 –
30 mi (40 – 48 km), with monaural (single
channel) FM having slightly more range
than stereo FM. External influences may
sometimes interfere with FM station re-
ception even if the FM station is within 25
mi (40 km). The strength of the FM signal is
directly related to the distance between
the transmitter and receiver. FM signals fol-
low a line-of-sight path, exhibiting many of
the same characteristics as light. For ex-
ample, they will reflect off objects.Fade and drif t: As your vehicle moves away
from a station transmitter, the signals will
tend to fade and/or drif t.
Static and flutter: During signal interfer-
ence 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 reflec-
tive characteristics of FM signals, direct and
reflected signals reach the receiver at the
same time. The signals may cancel each
other, resulting in momentary 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 subject 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 occurfor several seconds during ionospheric tur-
bulence 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 used for the first
time 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 the
vehicle outside of any metal or large build-
ing for satellite radio to receive all of the
necessary data.
No satellite radio reception is available and
“NO SAT” or “No Signal” is displayed when
the SAT band option is selected unless op-
tional satellite receiver and antenna are in-
stalled and a SiriusXM® Satellite Radio ser-
vice subscription is active. Satellite radio is
not available in Alaska, Hawaii and Guam.
Satellite radio performance may be af-
fected if cargo carried on the roof blocks
the satellite radio signal.
