2012 FORD F150 engine

Maintenance and modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Snow plow restriction
WARNING:Ford does not recommend the use of any F-150
model to be upfitted and equipped with snow plow hardware for
use as a snow plow vehicle.
Any modifications to a vehicle that raise the center of gravity can make it
more likely the vehicle will roll over as a result of a loss of control. Ford
Motor Company recommends that caution be used with any vehicle equipped
with a high load or device (such as ladder racks or pickup box cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction
or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where the
transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

FUEL PUMP SHUT-OFF
In the event of a moderate to severe collision, this vehicle is equipped
with a fuel pump shut-off feature that stops the flow of fuel to the
engine. Not every impact will cause a shut-off.
Should your vehicle shut off after a collision due to this feature, you may
restart your vehicle by doing the following:
1. Turn the ignition switch to the off position.
2. Turn the ignition switch to the on position.
In some instances the vehicle may not restart the first time you try to
restart and may take one additional attempt.
WARNING:Failure to inspect and if necessary repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected
by an authorized dealer after any collision.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace
the cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
