ignition NISSAN FRONTIER 2011 Owner´s 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. 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. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion 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 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.
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.

platinum-tipped spark plugs by cleaning or re-
gapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.

Two types of fuses are used. TypeAis used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes. If a type A fuse is used to replace a type B fuse,
the type A fuse will not be level with the fuse
pocket as shown in the illustration. This will not
affect the performance of the fuse. Make sure the
fuse is installed in the fuse box securely.
Type B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.
ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse. 1. Be sure the ignition switch and the headlight switch are OFF.
2. Open the engine hood.

E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on levelroads, have a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
CAUTION
●
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
● E-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline. ●
U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.

Bumper towing
The genuine NISSAN step bumper has provi-
sions to install a trailer hitch ball and is designed
to tow trailers of a maximum weight of 3,500 lb
(1,588 kg) .
To install a trailer hitch ball cut out the circle in the
center of the step bumper
A, then remove it to
install the trailer hitch ball.
Weight carrying hitches
A weight carrying or “dead weight” ball mount is
one that is designed to carry the whole amount of
tongue weight and gross weight directly on the
ball mount and on the receiver.
Weight distribution hitch
This type of hitch is also called a “load-leveling” or
“equalizing” hitch. A set of bars attach to the ball
mount and to the trailer to distribute the tongue
weight (hitch weight) of your trailer. Many ve-
hicles can’t carry the full tongue weight of a given
trailer, and need some of the tongue weight
transferred through the frame and pushing down
on the front wheels. This gives stability to the tow
vehicle.
A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs. Check with the
trailer and towing equipment manufacturers to
determine if they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the
surge brake, hitch or trailer manufacturer
to determine if and how this can be done.
Follow the instructions provided by the manufac-
turer for installing and using the weight-
distributing hitch system. General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface. With the ignition on and the doors closed,
allow the vehicle to stand for several minutes
so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the center of
the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that the front bumper
height is within0-.5inches (0 – 13 mm) of
the reference height measured in step 2. The
rear bumper should be no higher than the
reference height measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If the
rear bumper is higher than the measured
reference height when loaded, the vehicle
may handle unpredictably which could
cause a loss of vehicle control and cause
serious personal injury or property
damage.

9-30Technical and consumer information

Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition” when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds , the I/M
test condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”. Contact a NISSAN dealer to set the
“ready condition” or to prepare the vehicle for
testing.This vehicle is equipped with an Event Data Re-
corder (EDR) . The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle’s systems performed. The EDR
is designed to record data related to vehicle
dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
● How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded.
These data can help provide a better understand-
ing of the circumstances in which crashes and
injuries occur. NOTE: EDR data are recorded by
your vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR under
normal driving conditions and no personal data
(e.g. name, gender, age and crash location) are
recorded. However, other parties, such as law
enforcement, could combine the EDR data with the type of personally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer and NISSAN dealer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess to the vehicle or the EDR. EDR data will only
be accessed with the consent of the vehicle
owner or lessee or as otherwise required or per-
mitted by law.
