2012 NISSAN ALTIMA COUPE battery replacement

The light illuminates when the trunk lid is opened.
When the trunk lid is closed, the light goes off.
The light will go off after a period of time if the
trunk lid is left open, unless the ignition switch is
placed in the ON position.
For bulb replacement procedures, refer to “Exte-
rior and interior lights” in the “Maintenance and
do-it-yourself” section of this manual.The HomeLink
Universal Transceiver provides a
convenient way to consolidate the functions of up
to three individual hand-held transmitters into
one built-in device.
HomeLink Universal Transceiver:
● Will operate most Radio Frequency (RF)
devices such as garage doors, gates, home
and office lighting, entry door locks and se-
curity systems.
● Is powered by your vehicle’s battery. No
separate batteries are required. If the vehi-
cle’s battery is discharged or is discon-
nected, HomeLink will retain all program-
ming.
Once the HomeLink Universal Transceiver
is programmed, retain the original trans-
mitter for future programming procedures
(Example: new vehicle purchases) . Upon
sale of the vehicle, the programmed
HomeLink Universal Transceiver buttons
should be erased for security purposes. For
additional information, refer to “Program-
ming HomeLink” later in this section.WARNING
● Do not use the HomeLink Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards be-
came effective for opener models
manufactured after April 1, 1982) . A ga-
rage door opener which cannot detect
an object in the path of a closing garage
door and then automatically stop and
reverse, does not meet current federal
safety standards. Using a garage door
opener without these features in-
creases the risk of serious injury or
death.
● During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range) . Make sure that people or
objects are clear of the garage door,
gate, etc. that you are programming.
● Your vehicle’s engine should be turned
off while programming the HomeLink
Universal Transceiver.

CAUTION
●Be sure to carry the Intelligent Key with
you when operating the vehicle.
● Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating with
the vehicle as it receives radio waves. The Intel-
ligent Key transmits weak radio waves. Environ-
mental conditions may interfere with the opera-
tion of the Intelligent Key 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 equipment,
such as a cellular telephone, transceiver,
and 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 com-
puter. ●
When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is almost dis-
charged, insert the Intelligent Key into the Intelli-
gent Key port to start the engine. Replace the
discharged battery with a new one as soon as
possible. For more details, see “Push-button ig-
nition switch” in the “Starting and driving” sec-
tion.
Since the Intelligent Key is continuously receiving
radio waves, if the key is left near equipment
which transmits strong radio waves, such as sig-
nals from a TV and personal computer, the bat-
tery life may become shorter.
For information regarding replacement of a bat-
tery, see “Battery replacement” in the “Mainte-
nance and do-it-yourself” section.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN dealer.
CAUTION
Listed below are conditions or occur-
rences which will damage the Intelligent
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 modify the Intelligent
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 tem-
peratures 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.
Pre-driving checks and adjustments3-7

WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraft navigation and communi-
cation systems. Do not operate the In-
telligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally when the unit is stored for a
flight.
The Intelligent Key can operate all the door locks
using the remote controller function. The operat-
ing environment and/or conditions may affect the
Intelligent Key operation.
Be sure to read the following before using the
Intelligent Key.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift selector to N
(Neutral) . For CVT models, move the
shift selector to P (Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
CAUTION
● Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
● Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid. ●
Never leave the engine or the CVT re-
lated component harness connector
disconnected while the ignition switch
is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
● Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by a NISSAN dealer.
