engine FORD EXPEDITION 2017 3.G Workshop Manual

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control
light illuminates steadily if the
system detects a failure. Make sure
you did not manually disable the traction
control system using the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
traction control disabled could lead to an
increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active. Switching the System Off The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See Principle of
Operation (page 47).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates
either of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on:
• When you switch the traction control
system off.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving
braking system, aftermarket roof
racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. Remember that even advanced
technology cannot defy the laws of
physics. It’
s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the road;
this could reduce the operator ’s ability to
control the vehicle potentially resulting in
a loss of vehicle control, vehicle rollover,
personal injury and death. If your electronic
stability control system activates, SLOW
DOWN. The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.

BLIND SPOT INFORMATION
SYSTEM
WARNING
Never use the Blind Spot
Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. The Blind Spot Information System is
designed to aid you in detecting vehicles
that may have entered the blind spot zone
(A). The detection area is on both sides of
your vehicle, extending rearward from the
exterior mirrors to approximately
10 ft
(3 m) beyond the bumper. The system is
designed to alert you if certain vehicles
enter the blind spot zone while driving.
Cross Traffic Alert warns the driver of
vehicles approaching from the sides when
the transmission is in reverse (R). Note:
The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It’ s only designed to alert
you to vehicles in the blind spot zones.
Note: When a vehicle passes quickly
through the blind spot zone, typically fewer
than two seconds, the system does not
trigger.
Using the System
The Blind Spot Information System turns
on when you start the engine and you drive
your vehicle forward above
3 mph
(5 km/h). It remains on while the
transmission is in drive (D) or neutral (N).
If shifted out of drive (D) or neutral (N),
the system enters Cross Traffic Alert mode.
Once shifted back into drive (D), the Blind
Spot Information System turns back on
when the vehicle is driven above
3 mph
(5 km/h).
Note: The Blind Spot Information System
does not function in reverse (R) or park (P)
or provide any additional warning when a
turn signal is on.
Cross Traffic Alert detects approaching
vehicles from up to
46 ft (14 m) away
though coverage decreases when the
sensors are blocked. Reversing slowly
helps increase the coverage area and
effectiveness. WARNING
Never
use the Cross Traffic Alert
system as a replacement for using
the interior and exterior mirrors and
looking over your shoulder before backing
out of a parking space. Cross Traffic Alert
is not a replacement for careful driving. In this first example, the left sensor is only
partially obstructed; zone coverage to the
right is nearly maximized.

DRIVE CONTROL
Driver Select Suspension (If Equipped)
Driver select suspension delivers a unique
driving experience through a suite of
sophisticated electronic vehicle systems.
These systems continuously monitor your
driving inputs and the road conditions to
optimize ride comfort, steering and
handling.
Driver select suspension consists of the
following systems:
• Continuously controlled damping
dynamically adjusts the shock
absorbers stiffness in real time to
match the road surface and driver
inputs. This system continuously
monitors your vehicle ’s motion (roll,
pitch, bounce), suspension position,
load, speed, road conditions, and
steering to adjust the suspension
damping for optimal vehicle control.
• Electronically power-assisted steering
adjusts steering effort and feel based
on your vehicle speed and your inputs.
The configuration remains active until
modified from the main menu on the
information display. See
General
Information (page 91). Modes:
•
Comfort – Provides a more relaxed
driving experience, maximizing comfort.
Your steering effort decreases and the
suspension movement is more fluid.
Comfort mode is ideal when you desire
enhanced traveling comfort.
• Normal – Delivers a balanced
combination of comfortable, controlled
ride and confident handling. This mode
provides an engaging drive experience
and a direct connection to the road
without sacrificing any of the
composure demanded from your
vehicle.
• Sport – Provides a sportier driving
experience. The suspension stiffens,
with an emphasis on handling and
control. The engine responds more
directly to your inputs. Sport mode is
ideal for use during more spirited
driving.
SELF-LEVELING SUSPENSION
The self-leveling suspension system is
designed to improve ride, handling and
general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
• Towing
This system keeps the rear of your vehicle
at a constant level through a hydraulic
pump inside each rear shock. Depending
on the payload or road surface conditions
it will take approximately 2 mi (3.2 km) for
the leveling to complete.

Safety Compliance Certification Label
Example:
WARNING
Exceeding the Safety
Compliance Certification
label vehicle weight rating limits
could result in substandard
vehicle handling or performance,
engine, transmission and/or
structural damage, serious
damage to the vehicle, loss of
control and personal injury. Maximum Loaded Trailer
Weight
Maximum loaded trailer weight is
the highest possible weight of a
fully loaded trailer the vehicle can
tow. Consult an authorized dealer
(or the RV and Trailer Towing
Guide available at an authorized
dealer) for more detailed
information.
GCWR (Gross Combined
Weight Rating)
GCWR is the maximum allowable
weight of the vehicle and the
loaded trailer, including all cargo
and passengers, that the vehicle
can handle without risking
damage. (Important: The towing vehicle
’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note: For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower your
vehicle ’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. Exceeding any vehicle weight
rating limitation could result
in serious damage to your vehicle,
personal injury or both. 200

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.

TRAILER SWAY CONTROL WARNING
Turning off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. Ford
does not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation. Note:
This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See
Load
Carrying (page 196). RECOMMENDED TOWING
WEIGHTS
Note:
Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
below.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 36.5 feet² (3.39
meters²) if your vehicle is equipped
with the standard towing package,
or 60 feet² (5.57 meters²) if your
vehicle is equipped with the
optional heavy duty package.
Note: Exceeding this limitation
may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1000 feet (300 meters)
starting at the 1000 foot (300
meter) elevation point.

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.
