2012 NISSAN TITAN ECU

TOWING RECOMMENDED BY
NISSANTwo-wheel drive models
NISSAN recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flat bed truck as illustrated.
CAUTION
●
Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward) , as this may
cause serious and expensive damage to
the transmission. If it is necessary to
tow the vehicle with the front wheels
raised always use towing dollies under
the rear wheels.
● When towing automatic transmission
models with the front wheels on the
ground or on towing dollies:
– Place the ignition switch in the OFF position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may cause damage to the
lock mechanism (if so equipped) . If the speed or distance must necessarily be
greater, remove the propeller shaft before towing
to prevent damage to the transmission.

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money.
However, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition, as well as its emis-
sions and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hicles
before they work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* Tires should be rotated every
7,500 miles (12,000 km) .
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal. Automatic transmission P (Park) position
mechanism
On a fairly steep hill check that your
vehicle is held securely with the shift selector in
the P (Park) position without applying any brakes.
Brake pedal Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see a
NISSAN dealer immediately. Keep the floor mat
away from the pedal.
Brakes Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment,
see a NISSAN dealer.
Seats Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the locks (if so
equipped) hold securely in all latched positions.
Seat belts Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.

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. ●
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 automatic
transmission related component har-
nesses 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,
