2013 NISSAN ALTIMA COUPE battery replacement

NISSAN Intelligent Keyinsertion indica-
tor
This indicator illuminates when the Intelligent Key
needs to be inserted into the Intelligent Key port.
(For example, the Intelligent Key battery is dis-
charged.)
If this indicator illuminates, insert the Intelligent
Key into the Intelligent Key port in the correct
direction. See “Push-button ignition switch” in
the “Starting and driving” section.
NISSAN Intelligent Key removal indicator
This indicator illuminates when the driver’s door
is opened with the ignition switch placed in the
OFF position and the Intelligent Key placed in the
Intelligent Key port. A key reminder chime also
sounds.
If this indicator illuminates, remove the Intelligent
Key from the Intelligent Key port and take it with
you when leaving the vehicle.
NISSAN Intelligent Key battery discharge
indicator
This indicator illuminates when the Intelligent Key
battery is running out of power.
If this indicator illuminates, replace the battery
with a new one. See “Battery replacement” in the
“Maintenance and do-it-yourself” section. Loose fuel cap warning
This warning appears when the fuel-filler cap is
not tightened correctly after the vehicle has been
refueled. See “Fuel-filler cap” in the “Pre-driving
checks and adjustments” section.
Check tire pressure warning
This warning appears when the low tire pressure
warning light in the meter illuminates and low tire
pressure is detected. If this warning appears,
stop the vehicle and adjust the tire pressure to
the recommended COLD tire pressure shown on
the Tire and Loading Information label. See “Low
tire pressure warning light” earlier in this section
and “Tire Pressure Monitoring System (TPMS)”
in the “Starting and driving” section.
Your vehicle may has two types of security sys-
tems:
● Vehicle security system
● NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
or trunk lid when the system is armed. It is not,
however, a motion detection type system that
activates when a vehicle is moved or when a
vibration occurs.

To turn the map lights on, press the light lens. To
turn them off, press the lens again.
CAUTION
Do not use for extended periods of time
with the engine stopped. This could result
in a discharged battery.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.
When the HomeLink Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming proce-
dures (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.

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 additional information, see “Push
Button Ignition Switch” in the “Starting and driv-
ing” section.
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. If an Intelligent Key is lost or stolen, NISSAN
recommends erasing the ID code of that Intelli-
gent Key from the vehicle. This may prevent the
unauthorized use of the Intelligent Key to operate
the vehicle. For information regarding the erasing
procedure, contact a NISSAN dealer.

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. Move the shift selector to
P (Park) .
● Be sure the ignition key 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. ●
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.
●
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.
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.

NISSAN INTELLIGENT KEY
Replace the battery in the Intelligent Key as fol-
lows:1. Remove the mechanical key from the Intelli- gent Key.
2. Insert a small screwdriver
Ainto the slitB
of the corner and twist it to separate the
upper part from the lower part. Use a cloth to
protect the casing.
3. Replace the battery with a new one. Recommended battery: CR2032 or equiva-
lent.
●Do not touch the internal circuit and elec-
tric terminals as doing so could cause a
malfunction.
● Hold the battery by the edges. Holding
the battery across the contact points will
seriously deplete the storage capacity.
● Make sure that the + side faces the bot-
tom of the case. 4. Close the lid securely as illustrated
