engine FORD EXPEDITION 2019 Repair Manual

It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control or roll over. Remember, your
safety and the safety of others should be
your primary concern.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle, for example, turn the steering
wheel only as rapidly and as far as required
to avoid the emergency. Excessive steering
can result in loss of vehicle control. Apply
smooth pressure to the accelerator pedal
or brake pedal when changes in vehicle
speed are required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle roll over, loss
of vehicle control and personal injury. Use
all available road surface to bring your
vehicle to a safe direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of
surface to another, for example, from
concrete to gravel, there is a change in the
way your vehicle responds to a maneuver,
for example, steering, acceleration or
braking.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation
maximizes the engine and transmission
cooling capability.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck
to the point that assistance may be
required from another vehicle. Remember,
you may be able to back out the way you
came if you proceed with caution.
Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying improves
by applying light pressure to the brake
pedal when slowly moving.

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Four-Wheel Drive (If Equipped)

Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should always
try to drive straight up or straight down.
Note: Avoid turning on steep slopes or
hills. A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you want to use. Do
not drive over the crest of a hill without
seeing what conditions are on the other
side. Do not drive in reverse over a hill
without the aid of an observer.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn
around because this could cause vehicle
roll over. It is better to reverse back to a
safe location.
Apply just enough power to the wheels to
climb the hill. Too much power can cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control. Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral. Disengage
overdrive or move the transmission
selector lever to a lower gear. When
descending a steep hill, avoid sudden hard
braking as you could lose control. The front
wheels have to be turning in order to steer
your vehicle.
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.
Driving on Snow and Ice
WARNING: If you are driving in
slippery conditions that require tire
chains or cables, then it is critical that
you drive cautiously. Keep speeds down,
allow for longer stopping distances and
avoid aggressive steering to reduce the
chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
Note: Excessive tire slippage can cause
transmission damage.
211

(If Equipped)E143949

Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide when driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it does not stop any faster
as braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Hints on Driving With
Anti-Lock Brakes (page 215).
If Your Vehicle Gets Stuck In Mud or
Snow WARNING: Do not spin the wheels
at over
34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur. Note:
Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Always fully apply the
parking brake. Make sure you shift into
park (P) for vehicles with an automatic
transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle.
On some four-wheel drive vehicles, when
the transfer case is in the neutral (N)
position, the engine and transmission
disconnect from the rest of the driveline.
Therefore, your vehicle is free to roll even
if it is parked. Do not leave your vehicle
unattended with the transfer case in the
neutral (N) position. Always set the parking
brake fully and turn off the ignition when
leaving your vehicle.
Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty. For this reason,
we strongly recommend that you do not
make modifications such as adding or
removing parts, for example, lift kits or
stabilizer bars or by using replacement
parts not equivalent to the original factory
equipment.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 354). See
Warning Lamps and
Indicators (page 109).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Switch the engine off, move the
transmission to park (P) and apply the
parking brake. Inspect the accelerator
pedal and the area around it for any items
or debris that may be obstructing its
movement.If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer. Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at
which you press the brake pedal. It
provides maximum braking efficiency as
long as you press the pedal. Emergency
brake assist can reduce stopping distances
in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you switch the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the anti-lock braking system may
be disabled. Have the system checked by
an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective. If the brake warning lamp
illuminates with the parking
brake released, have your brake
system serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock braking system does not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.

Push the switch downward.
The red warning lamp turns off.
If it remains illuminated or flashes, the
system has malfunctioned. Have your
vehicle checked as soon as possible.
Pulling Away on a Hill When Towing a
Trailer
Press and hold the brake pedal.
Pull the switch upward and hold
it.
Shift into gear.
Press the accelerator pedal until engine
has developed sufficient torque to prevent
your vehicle from rolling down the hill. Release the switch and pull
away in a normal manner.
Automatically Releasing the
Electric Parking Brake
Close the driver door.
Shift into gear.
Press the accelerator pedal and pull away
in a normal manner. The red warning lamp turns off.
If it remains illuminated or flashes, the
electric parking brake has not released.
Manually release the parking brake. Releasing the Electric Parking
Brake if the Vehicle Battery is
Running Out of Charge
Connect a booster battery to the vehicle
battery to release the electric parking brake
if the vehicle battery is running out of
charge. See Jump Starting the Vehicle
(page 308).
HILL START ASSIST WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system will turn
off if a malfunction is apparent or if you
rev the engine excessively. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal.
The system releases the brakes
automatically once the engine has

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 information
display controls or 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
the 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 64).
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.
• When you select an alternative stability

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
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.

Automatic Cancellation
Automatic cancellation can also occur
when:
•
The tires lose traction.
• You apply the parking brake.
Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open
the door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three
minutes.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode or switch the ignition off.
Note: You erase the set speed when you
switch the system off. Detection Issues WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.
