2018 NISSAN TITAN battery replacement

Maintenance
The maintenance menu allows the user to
set reminders for various vehicle mainte-
nance items.
WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. For addi-
tional information, refer to “Changing
wheels and tires” in the “Do-it-yourself ”
section of this manual. Many factors in-
cluding tire inflation, alignment, driving
habits and road conditions affect tire
wear and when tires should be re-
placed. Setting the tire replacement in-
dicator for a certain driving distancedoes not mean your tires will last that
long. Use the tire replacement indicator
as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pres-
sure checks could result in tire failure.
Serious vehicle damage could occur
and may lead to a collision, which could
result in serious personal injury or
death.

2-44Instruments and controls

WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ The Intelligent Key transmits radio waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
∙ Never leave the Intelligent Key in the vehicle when you leave the vehicle.
The Intelligent Key system can operate all
the door locks using the remote control
function or pushing the request switch on
the vehicle without taking the key out from
a pocket or purse. The operating environ-
ment and/or conditions may affect the In-
telligent Key system operation.
Be sure to read the following before using
the Intelligent Key system.
CAUTION
Be sure to carry the Intelligent Key with
you when operating the vehicle.
The Intelligent Key is capable of receiving
and transmitting radio waves. The Intelli-
gent Key system transmits weak radio
waves from various distances. Environ-
mental conditions may interfere with the
operation of the Intelligent Key system un-
der 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, a
yellow indicator illuminates with the mes-
sage “Warning, Key ID Incorrect” in the ve-
hicle information display (if so equipped).
When the Intelligent Key battery is low, the
NISSAN Intelligent Key® warning light (if so
equipped) will blink green. For additional
information, refer to “Vehicle information
display warnings and indicators” in the “In-
struments and controls” section of this
manual.
Since the Intelligent Key is capable of 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.

∙ If the Intelligent Key battery dis-
charge indicator appears, replace the
battery as soon as possible. For addi-
tional information, refer to “Battery
replacement” in the “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 auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch in the ON po- sition 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 in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, Diesel Exhaust Fluid
(Diesel only) 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 appear- ance and condition. Also check tires for
proper inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions 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 ve-
hicle from moving. Move the shif t le-
ver to P (Park)
∙ Be sure the ignition switch is in the OFF or LOCK position when perform-
ing 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙
The automatic engine cooling fan (if so
equipped) may come on at any time
without warning, even if the ignition
switch is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative bat-
tery 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, sup-
port 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 rec-
ommended that you visit a NISSAN
dealer for service of the fuel filter or
fuel lines.
CAUTION
∙ Do not work under the hood while theengine 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 automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer 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.
