relay FORD EXPEDITION 2020 Owners Manual

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 315).
Some vehicles may have the
ability to modify trailer towing
features. See Towing (page 275
).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
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 ball mount with the
correct rise or drop and load
capacity. 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
269).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

CHANGING A FUSE
Fuses WARNING: 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. 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.
