2012 NISSAN FRONTIER Battery

Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator.
The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.
1. Power steering fluid pump
2. Automatic belt tensioner
3. Cooling fan
4. Air conditioner compressor
5. Crankshaft pulley
6. Generator
WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly. 1. Visually inspect the belt for signs of unusual
wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted by a NISSAN dealer.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in the
“NISSAN Service and Maintenance Guide”.

Extended storage switch
If any electrical equipment does not operate,
remove the extended storage switch and check
for an open fuse.
NOTE:
The extended storage switch is used for
long term vehicle storage. Even if the ex-
tended storage switch is broken it is not
necessary to replace it. Replace only the
open fuse in the switch with a new fuse.How to replace the extended storage switch:
1. To remove the extended storage switch, be sure the ignition switch is in the OFF or
LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
1found on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box

KEYFOB (if so equipped)
Replace the battery in the keyfob as follows:
1Open the lid using a coinA.
2Remove the batteryB.
3Install a new batteryCwith the “+” facing
down.
● Hold the battery by the edges. Holding the
battery across the contact points will seri-
ously deplete the storage capacity. ●
Do not touch the internal circuit and electric
terminals as it could cause a malfunction.
● When changing the battery, do not let dust
or oil get on the keyfob.
● There is danger of explosion if a lithium bat-
tery is incorrectly replaced. Replace only
with the same or equivalent type.
Recommended battery: CR2025 or equivalent.
4Close the lid securely.
5. Press the
button, then thebutton two or three times to check the key-
fob operation.
If the battery is removed for any reason
other than replacement, perform step 5. ● An improperly disposed battery can
hurt the environment. Always confirm
local regulations for battery disposal.
● The keyfob is water-resistant; how-
ever, if it does get wet, immediately
wipe completely dry.
● The operational range of the keyfob
extends to approximately 33 ft (10 m)
from the vehicle. This range may vary
with conditions.

Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more
that 15 milliamps from the stop and tail
lamp circuits. Using a module/converter
that exceeds these power requirements
may damage the vehicle’s electrical sys-
tem. See a reputable trailer dealer to ob-
tain the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer or repu-
table trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped with a
7-pin trailer harness connector. A flat 4–pin har-
ness is available from your dealer for vehicles
without a tow package. If your trailer is equipped
with a flat 4-pin connector, an adapter will be needed to connect the trailer lights to the vehicle.
Adapters are available at auto parts stores and
hitch retailers.Trailer brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
Vehicles equipped with a 7–pin trailer harness
connector are pre-wired for a trailer brake con-
troller. See a NISSAN dealer for a trailer brake
adapter harness.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
When towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used. However, most states
require a separate braking system on trailers with
a loaded weight above a specific amount. Make
sure the trailer meets the local regulations and
the regulations where you plan to tow.
Several types of braking systems are available.
Surge Brakes - The surge brake actuator is
mounted on the trailer tongue with a hydraulic line
running to each trailer wheel. Surge brakes are
activated by the trailer pushing against the hitch ball when the tow vehicle is braking. Hydraulic
surge brakes are common on rental trailers and
some boat trailers. In this type of system, there is
no hydraulic or electric connection for brake op-
eration between the tow vehicle and the trailer.
Electric Trailer Brakes -
Electric braking sys-
tems are activated by an electronic signal sent
from a trailer brake controller (special brake-
sensing module) . If electric trailer brakes are
used, see Electric trailer brake controller in this
section.
Have a professional supplier of towing equip-
ment make sure the trailer brakes are properly
installed and demonstrate proper brake function
testing.
Electric trailer brake controller
Trailers equipped with electric brakes may re-
quire the installation of an aftermarket trailer
brake controller.
A Genuine NISSAN jumper harness is available
that is specifically designed to be used when
installing an aftermarket brake controller.
Install the aftermarket electric trailer brake con-
troller according to the manufacturer’s instruc-
tions.

port Canada’s Road Safety 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
