2015 FORD F150 relay

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See the Fuses
chapter.
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a tow bar with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
233). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

•
The tire air pressures recommended
for general driving are on the vehicle ’s
Safety Certification Label. The
maximum cold inflation pressure for
the tire and associated load rating are
on the tire sidewall. Tire air pressure
may require re-adjustment within these
pressure limits to accommodate the
additional weight of the snowplow
installation.
• Federal and some local regulations
require additional exterior lamps for
snowplow-equipped vehicles. Contact
an authorized dealer for additional
information.
Snowplow Mode (If Equipped)
Press the snowplow button on the
instrument panel to switch on snowplow
mode. The button illuminates when in
snowplow mode. A message appears in
the information display indicating that
features are turned off when in snowplow
mode.
The following features are disabled when
in snowplow mode:
• 110V inverter.
• Fog lamps.
• Heated steering wheel.
• Heated front and rear seats.
• Massaging seats.
The body module also activates the
snowplow relay that provides power to
aftermarket snowplow controls.
Switch off snowplow mode by pressing
the snowplow button or switching off the
ignition. The snowplow button is no longer
illuminated and features are turned on. Note:
The electrical system is designed to
support the addition of a residential
snowplow (up to 60 Amps continuous) and
snowplow lights (up to 20 Amps
continuous) using snowplow mode. The
system is not designed to support snowplow
usage with additional electrical aftermarket
accessories.
Operating the Vehicle with the
Snowplow Attached
Note: Drive the vehicle at least 500 miles
(800 kilometers) before using your vehicle
for snow removal.
We recommend vehicle speed does not
exceed 45 mph (72 km/h) when
snowplowing.
The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature.
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals.
Snowplowing with your Airbag
Equipped Vehicle WARNINGS
Do not attempt to service, repair, or
modify the airbag supplemental
restraint system (SRS) or its fuses.
Contact a Ford or Lincoln dealer.

FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. The power distribution box is located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 308).

The fuse panel is in the right-hand side of
the passenger footwell behind a trim panel.
To remove the trim panel, pull it toward
