Ford Expedition (2018 year). Manual — part 49

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 will cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control.

E143949

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.

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 while 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 will 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 202).

(If Equipped)

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

WARNINGS

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.

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.

We recommend that you use caution when
your vehicle has either a high load or device
(such as ladders or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle
to roll over when there is a loss of vehicle
control.

Failure to maintain your vehicle correctly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off road usage.

(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 119).

Locking Function

(If Equipped)

E163170

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 338).

E138644

See Warning Lamps and
Indicators

(page 104).

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.

E138644

If the brake warning lamp
illuminates with the parking
brake released, have your brake

system serviced immediately.

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.

•

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.
