2018 FORD EXPEDITION warning

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.

(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 211).
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.

(If Equipped)

LIMITED SLIP DIFFERENTIAL
(IF EQUIPPED)
The Electronic Limited Slip Differential
(eLSD) system directs torque, enabling the
vehicle to drive over terrain and road
conditions that a conventional axle cannot.
The system is active at all times and
requires no input from the driver.
Note:
If your vehicle is not at optimal
operating conditions or a system fault is
present, a warning may be displayed in the
instrument cluster. Depending on the
warning, your vehicle may need to be
serviced. For more information regarding the
system information messages, See
Information Messages (page 123).
Locking Function
(If Equipped) The lock button engages
‘locker
mode ’.
With the locker engaged, the system
electronically locks the differential causing
both half shafts to turn at the same rate.
This increases traction during off road
events.
The locker mode may automatically
disengage based on certain conditions
such as vehicle speed. When engaged, a
telltale in the instrument cluster will
illuminate amber and the switch button
will be illuminated. When the speed is
exceeded the telltale will turn gray, the
locker will be disengaged and be in
standby mode until the speed conditions
are met. If the eLSD system is faulted and
the locker cannot engage, a warning
message will be displayed in the
instrument cluster and the switch button
will flash. Spare Tire
If your vehicle is equipped with an
Electronic Limited Slip Differential, a spare
tire of a different size than the tire
provided, should not be used. If a spare tire
is installed, a message may appear,
indicating the system has disabled
automatically or reduced function to
prevent system overheat and damage. It
is recommended to reinstall the repaired
or replaced road tire as soon as possible.
When the road tire is replaced, the system
will resume normal operation on the next
key cycle.
Trailer Towing
The Electronic Limited Slip Differential
enhances vehicle stability during trailer tow
operation. During high demand trailering
events (such as steep grades, high speeds
or with a spare tire), the system may
provide a warning in the instrument cluster
and reduce function or enter a temporarily
disabled state. To resume normal function,
stop the vehicle in a safe location and
allow the unit to adequately cool. Once
the system has reached normal operating
temperatures, system function will be
restored and the Electronic Limited Slip
Differential Restored message will be
displayed.

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 349). See
Warning Lamps and
Indicators (page 106).
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.
211
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- BrakesE138644 E138644

•
You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
ELECTRIC PARKING BRAKE WARNING: Always fully apply the
parking brake and make sure you shift
into park (P). Failure to follow this
instruction could result in personal injury
or death. WARNING:
If you drive extended
distances with the parking brake applied,
you could cause damage to the brake
system. WARNING:
The electric parking
brake does not operate if the vehicle
battery is running out of charge.
Your vehicle has an electric parking brake.
You operate it with a switch instead of a
lever. The switch is on the center console
or to the left-hand side of the steering
wheel, on the lower part of the instrument
panel.
Note: The electric parking brake makes
noises during operation. This is normal.
Applying the Electric Parking
Brake Pull the switch upward.
The red warning lamp flashes
during operation and illuminates
when the parking brake is
applied. Note:
It remains illuminated for a short
period of time after you switch the ignition
off.
If it continues to flash or does not
illuminate, the system has malfunctioned.
Have your vehicle checked as soon as
possible.
Note: You can apply the electric parking
brake when the ignition is off.
Note: The electric parking brake could
automatically apply when you shift into park
(P). See
Transmission (page 195).
Applying the Electric Parking Brake in
an Emergency
Note: Do not apply the electric parking
brake when your vehicle is moving, except
in an emergency. If you repeatedly use the
electric parking brake to slow or stop your
vehicle, you could cause damage to the
brake system.
You can use the electric parking brake to
slow or stop your vehicle in an emergency. Pull the switch upward and hold
it.

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 302).
HILL START ASSIST WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. 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.
Note: If the engine is revved excessively, or
if a malfunction is detected, the system will
be deactivated.
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 will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes release automatically
213
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- BrakesE267156 E270480 E267156 E267156 E270480

when the engine has sufficient torque to
prevent your vehicle from rolling down the
grade. This is an advantage when pulling
away on a slope, for example from a car
park ramp, traffic lights or when reversing
uphill into a parking space.
The system will activate automatically on
any slope that will cause significant vehicle
rollback. For vehicles with a manual
transmission, you can switch this feature
off using the information display. See
Information Displays (page 111). The
system will remain on or off depending on
how it was last set.
Note: There is no warning lamp to indicate
the system is either on or off.
Note: If your vehicle is equipped with Auto
Hold, Hill Start Assist will not be available
while Auto Hold is active.
Using Hill Start Assist
1. Bring your vehicle to a complete standstill. Keep the brake pedal
pressed and select an uphill gear (for
example, drive (D) or first (1) when
facing uphill or reverse (R) when facing
downhill).
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time will automatically be extended if
you are in the process of driving off.
4. Drive off in the normal manner. The brakes will release automatically. Switching the System On and Off
You can switch this feature on or off if your
vehicle is equipped with a manual
transmission and an information display.
See
General Information (page 111). The
system remembers the last setting when
you start your vehicle.
If your vehicle is not equipped with a
manual transmission and an information
display, you cannot turn the system on or
off. When you switch the ignition on, the
system automatically turns on.

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 61).
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
control mode.
