battery replacement NISSAN SENTRA 2016 B17 / 7.G Owners Manual

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 system transmits weak radio waves.
Environmental conditions may interfere with the
operation 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 equipment,
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 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 two years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is low, the Intel-
ligent Key system warning light (
) will blink
green for about 30 seconds after the ignition
switch is placed in the ON position.
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, refer to “Battery replacement” in the “Main-
tenance and do-it-yourself” section of this
manual.
As many as four Intelligent Keys can be regis-
tered and used with one vehicle. For information
about the purchase and use of additional Intelli-
gent Keys, it is recommended that you visit 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 adjustments3-11

Alarm and warning when the engine
starts
When the Intelligent Key system warning light
(
) blinks red and the outside buzzer
sounds, make sure the Intelligent Key is inside the
vehicle.
Warning for low battery power
When the Intelligent Key battery is low, the Intel-
ligent Key system warning light (
) will blink
green for about 30 seconds after the ignition
switch is placed in the ON position. This warning
is to let you know that the battery of the Intelligent
Key will run down soon. Replace it with a new
one. For additional information, refer to “Battery
replacement” in the “Maintenance and do-it-
yourself” section of this manual.
It is recommended you replace the battery at a
NISSAN dealer.
Preventing the Intelligent Key from
being left in the vehicle
If you lock all doors using the power door lock
switch with the Intelligent Key in the vehicle, all of
the doors unlock immediately and the buzzer will
warn you when the door is closed.
Pre-driving checks and adjustments3-21

4. Push the ignition switch while depressingthe brake pedal within ten seconds after the
chime sounds. The engine will start.
NOTE: ● When the ignition switch is pushed to the
ACC or ON position or the engine is started
by the above procedure, the Intelligent Key
battery discharge indicator appears in the
vehicle information display even when the
Intelligent Key is inside the vehicle. This is
not a malfunction. To turn off the Intelligent
Key battery discharge indicator, touch the
ignition switch with the Intelligent Key again.
● If the Intelligent Key battery discharge indi-
cator appears, replace the battery as soon
as possible. For additional information, refer
to “Battery Replacement” in the “Mainte-
nance and do-it-yourself” section of this
manual.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake and clutch fluid (if so equipped) ,
and windshield-washer fluid as frequently as
possible, or at least whenever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head
restraints/headrests.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is placed in the ON posi-
tion. For additional information, refer to
“Warning lights, indicator lights and audible
reminders” in the “Instruments and controls”
section of this manual.

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 lever to N (Neu-
tral) . For Continuously Variable Trans-
mission (CVT) models, move the shift
lever 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.
● Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
●
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.
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 transmis-
sion related component harness con-
nector 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. For additional information, refer to “Owner’s
Manual/Service Manual order 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, it
is recommended that you have it done by a
NISSAN dealer.
