2017 FORD EXPEDITION suspension

If the loaded vehicle is not moved for
approximately 12 hours, the leveling system
may bleed down to a lower height. This
can be especially apparent if a trailer is left
attached to the parked vehicle for long
periods of time. You must drive your vehicle
in order to re-level the suspension.
If a self-equalizing hitch is used, your
vehicle should be driven approximately
2 mi (3.2 km) with the trailer prior to
adjusting (leveling) the hitch.

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. Note:
Do not exceed the GVWR or
the GAWR specified on the
certification label. See
Recommended Towing Weights
(page
204).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 233).
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. 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
198).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

Integrated Hitch Rating
WARNING
Towing trailers beyond the maximum
tongue weight exceeds the limit of
the towing system and could result
in vehicle structural damage, loss of vehicle
control and personal injury. The standard integrated hitch has two
ratings depending on mode of operation:
•
Weight-carrying mode requires a draw
bar and hitch ball. The draw bar
supports all the vertical tongue load of
the trailer.
• Weight-distributing mode requires an
aftermarket weight-distributing
system, which includes draw bar, hitch
ball, spring bars and snap-up brackets.
This system distributes the vertical
tongue load of the trailer between the
truck and the trailer. Maximum Tongue Weight
Maximum Trailer Weight
Mode
600 lb (272 kg)
6000 lb (2721 kg)
Weight carrying
920 lb (417 kg)
9200 lb (4173 kg)
Weight distributing
Note: These are hitch ratings only. Actual
vehicle ratings are dependent on engine,
transmission and axle combinations.
Weight-distributing Hitch - Vehicles
without Automatic Leveling
Suspension WARNING
Do not adjust a weight-distributing
hitch to any position where the rear
bumper of the vehicle is higher than
it was before attaching the trailer. Doing
so will defeat the function of the
weight-distributing hitch, which may cause
unpredictable handling, and could result
in serious personal injury. When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1. 3.
Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
half the way down from H2, toward H1.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6.
When the trailer is level or slightly nose
down toward the vehicle:
• Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting, and trailer
brake controls as required by law or the
trailer manufacturer.

Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud or sand, do not
rapidly spin the tires; spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds. Do not spin the wheels at
over 34 mph (55 km/h). The
tires may fail and injure a
passenger or bystander. Driving habits have a great deal
to do with your tire mileage and
safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on
the road
*Do not run over curbs or hit the
tire against a curb when parking
Highway Hazards
No matter how carefully you drive
there
’s always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important. If you feel a sudden vibration or
ride disturbance while driving, or
you suspect your tire or vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and
replace it with your spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you’re
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.

USING SNOW CHAINS
WARNING
Snow tires must be the same size,
load index and speed rating as those
originally provided by Ford. Use of
any tire or wheel not recommended by
Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of control,
vehicle rollover, personal injury and death.
Additionally, the use of non-recommended
tires and wheels can cause steering,
suspension, axle, transfer case or power
transfer unit failure. Follow the Ford
recommended tire inflation pressure found
on the Safety Compliance Certification
Label (on the door hinge pillar, door latch
post or the door edge that meets the door
latch post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and adversely
affect the way your vehicle handles. Note:
The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow
tires and chains: •
If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an
accessory or equivalent. Other
conventional link type chains may
contact and cause damage to the
vehicle's wheel house and/or body.
• Do not install chains on the front tires
as this may interfere with suspension
components.
• Only certain snow cables or chains
have been approved by Ford/Lincoln
as safe for use on your vehicle with the
following tires: 265/70R17 and
275/65R18.
• You should install snow cables or
chains that have been rated as SAE
Class S.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines, or fuel lines.
• Do not exceed 31 mph (50 km/h) or
less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.

Tire Change Procedure
WARNINGS
Only use replacement tires and
wheels that are the same size, load
index, speed rating and type (such
as P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended tire
and wheel size may be found on either the
Safety Compliance Certification Label
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver ’s seating position) or the Tire Label
which is located on the B-Pillar or edge of
the driver ’s door. If this information is not
found on these labels then you should
contact your authorized dealer as soon as
possible. Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of
loss of vehicle control, vehicle rollover,
personal injury and death. Additionally the
use of non-recommended tires and wheels
could cause steering, suspension, axle,
transfer case or power transfer unit failure.
If you have questions regarding tire
replacement, contact your authorized
dealer as soon as possible. When one of the front wheels is off
the ground, the transmission alone
will not prevent the vehicle from
moving or slipping off the jack. To help prevent the vehicle from
moving when you change a tire, be
sure to place the transmission in park
(P), set the parking brake and block (in
both directions) the wheel that is
diagonally opposite (other side and end of
the vehicle) to the tire being changed. Never get underneath a vehicle that
is supported only by a jack. If the
vehicle slips off the jack, you or
someone else could be seriously injured. WARNINGS
Do not attempt to change a tire on
the side of the vehicle close to
moving traffic. Pull far enough off the
road to avoid the danger of being hit when
operating the jack or changing the wheel. Always use the jack provided as
original equipment with your vehicle.
If using a jack other than the one
provided as original equipment with your
vehicle, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. Disable the power running boards
before jacking, lifting, or placing any
object under the vehicle. Never place
your hand between the power running
board and the vehicle as extended power
running boards will retract when the doors
are closed. Failure to follow these
instructions may result in personal injury. Failure to follow these instructions
when using the spare tire carrier
could cause loss of the wheel and
tire and lead to personal injury: Only use
the spare tire carrier to stow the tire and
wheel combination specified on the Tire
Label or Safety Compliance Certification
Label on the B-Pillar or the edge of the
driver door. Other tire and wheel
combinations could cause the carrier to
fail if it does not fit securely or is too heavy.
Do not use impact tools or power tools
operating over 200 RPM, which may cause
winch malfunction and prevent a secure
fit. Override the winch at least three times
(there will be an audible click each time)
to ensure a tight secure fit of the wheel and
tire. Note:
Passengers should not remain in the
vehicle when the vehicle is being jacked.
