warning light FORD EXPEDITION 2018 Service Manual

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.

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.

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.

PRINCIPLE OF OPERATION
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
Hill descent control
does not provide hill hold at zero miles
per hour (0 kilometers per hour). When
stopped, you must apply the parking
brake or place the vehicle in P (Park), or
it may roll away.
Hill descent control allows you to set and
maintain vehicle speed while descending
steep grades in various surface conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 2 mph
(3 km/h) and 12 mph (20 km/h). Above 20
mph (32 km/h), the system remains
armed, but you cannot use the system to
set or maintain the descent speed.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system provides a
warning in the message center and a tone
sounds when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. USING HILL DESCENT
CONTROL Press and release the hill
descent button on the
instrument panel. The button
illuminates and a chime sounds when you
switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent
speed, press the brake pedal until you
reach the desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.
Hill Descent Modes
• At speeds between
2 mph (3 km/h)
and 20 mph (32 km/h): When you
press this button, the light flashes
indicating this feature is active. Your
vehicle maintains the speed you desire
while in this mode.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): When you
press this button, the light is solid and
a message appears in the information
display indicating this feature is active.
Your vehicle does not maintain the
speed you desire and you cannot set
your descent speed.

Action
Cause
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. This happens, for example, when driving in sparse rural or desert
environments. A false blocked condition either self clears, or clears after you restart your
vehicle.
Switching to Normal Cruise
Control WARNING: Normal cruise control
will not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary.
You can change from adaptive cruise
control to normal cruise control through
the information display. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
