2017 FORD E SERIES relay

TOWING A TRAILER
WARNINGS
Do not exceed the Gross
Vehicle Weight Rating or the
Gross Axle Weight Rating
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, for example fuses or relays,
related to towing. See Fuses
(page 125).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading your 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
correct trailer loading and setting
your vehicle up for towing is
located in another chapter of this
Owner's Manual. See
Load Limit
(page 95). You can also find the
information in the RV & Trailer
Towing Guide. See an authorized
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. Note:
If your vehicle is equipped with dual
batteries, disconnecting the primary
under-hood battery does not remove power
from all circuits.
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 the battery has been disconnected and
reconnected, you will need to reset some
features. See Changing the 12V Battery
(page 145). Protected components

Panel WARNING
Always disconnect the battery before
servicing high current fuses. Note:
If your vehicle is equipped with dual
batteries, disconnecting the primary
under-hood battery does not remove power
from all circuits.
The fuse panel is located to the left of the
brake pedal and mounted onto the lower
left cowl panel. Remove the fuse panel
cover to access the fuses.
To remove a fuse, use the fuse puller tool
provided on the inside of the fuse panel
cover.
