2020 NISSAN ALTIMA battery

If you live in Canada or you are having diffi-
culties training a gate operatororgarage
door opener by using the “Training” proce-
dures, replace “Programming HomeLink®”
step 2 with the following:
NOTE:
When programming a garage door
opener, etc., unplug the device during
the “cycling” process to prevent possible
damage to the garage door opener com-
ponents. 1. For additional information, refer to “Pro- gramming HomeLink®” step 1 in this
section.
2. Using both hands, simultaneously press and hold the desired HomeLink®
button and the hand-held transmitter
button. During training, your hand-held
transmitter may automatically stop
transmitting. Continue to press and
hold the desired HomeLink® button
while you press and re-press (“cycle”)
your hand-held transmitter every
2 seconds until the frequency signal
has been learned. The HomeLink® indi-
cator light will flash slowly and then
rapidly af ter several seconds upon
successful training. DO NOT release un-
til the HomeLink® indicator light flashes slowly and then rapidly. When the indi-
cator light flashes rapidly, both buttons
may be released. The rapid flashing in-
dicates successful training.
Proceed with “Programming
HomeLink®” step 3 to complete.
If the device was unplugged during the
programming procedure, remember
to plug it back in when programming is
completed.
OPERATING THE HOMELINK®
UNIVERSAL TRANSCEIVER
The HomeLink® Universal Transceiver, af ter
it is programmed, can be used to activate
the programmed device. To operate, sim-
ply press and release the appropriate pro-
grammed HomeLink® Universal Trans-
ceiver button. The amber indicator light will
illuminate while the signal is being trans-
mitted.
For convenience, the hand-held transmit-
ter of the device may also be used at any
time.
PROGRAMMING TROUBLE-
DIAGNOSIS
If the HomeLink® does not quickly learn the
hand-held transmitter information:
∙ Replace the hand-held transmitter bat- teries with new batteries.
∙ Position the hand-held transmitter with its battery area facing away from the
HomeLink® surface.
∙ Press and hold both the HomeLink® and hand-held transmitter buttons
without interruption.
∙ Position the hand-held transmitter 1 - 3 inches (26 - 76 mm) away from the
HomeLink® surface. Hold the transmit-
ter in that position for up to 15 seconds.
If HomeLink® is not programmed within
that time, try holding the transmitter in
another position – keeping the indicator
light in view at all times.
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
2-70Instruments and controls

∙ 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, an
indicator illuminates in the vehicle informa-
tion display. For additional information, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
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 additional information, 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.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelli-
gent Key:
∙ Do not allow the Intelligent Key, which
contains electrical components, to
come into contact with water or salt
water. This could affect the system
function.
∙ Do not drop the Intelligent Key.
∙ Do not strike the Intelligent Key sharply against another object.
∙ Do not change or modif y the Intelli- gent Key.
∙ Wetting may damage the Intelligent Key. If the Intelligent Key gets wet, im-
mediately wipe until it is completely
dry.
∙ Do not place the Intelligent Key for an extended period in an area where
temperatures exceed 140°F (60°C). ∙ Do not attach the Intelligent Key with
a key holder that contains a magnet.
∙ Do not place the Intelligent Key near equipment that produces a magnetic
field, such as a TV, audio equipment
and personal computers.
If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that
Intelligent Key from the vehicle. This may
prevent the unauthorized use of the Intelli-
gent Key to operate the vehicle. For infor-
mation regarding the erasing procedure, it
is recommended that you visit a NISSAN
dealer.

Intelligent Key button operation
light
The light blinks only when you press any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes. If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, refer
to “Battery replacement” in the “Do-it-
yourself ” section of this manual.
WARNING SIGNALS
