2015 FORD EXPEDITION warning light

PRINCIPLES 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
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power.
Turn the traction control system off by pressing the
stability control button located on the center of the
instrument panel.
System indicator lights and messages
WARNING:If a failure has been detected within the traction
control system, the stability control light will illuminate steadily.
Verify that the traction control system was not manually disabled using
the stability control button. If the stability control light still illuminates
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 stability control light temporarily illuminates on engine
start-up and flashes when a driving condition activates the
stability system.
The stability control off light temporarily illuminates on engine
start-up and stays on when the traction control system is
turned off or if a problem occurs in the stability system.

HILL DESCENT CONTROL™ (IF EQUIPPED)
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 mph (0 km/h). When stopped, the parking brake must be
applied and/or the vehicle must be placed in P (Park) or it may roll
away.
Hill descent control allows the driver 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 3 mph (5 km/h) and 20 mph (32 km/h). Above 20 mph
(32 km/h), the system remains armed, but descent speed cannot be set
or maintained.
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 will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.
To enable hill descent control and set the descent speed, do the
following:
1. Press and release the hill descent button located in the
center of the terrain management control. A light in the
control will illuminate and chime will sound when this feature
is activated.
2. To increase descent speed, press the accelerator pedal until the
desired speed is reached. To decrease descent speed, press the brake
pedal until the desired speed is reached.
Whether accelerating or decelerating, once the desired descent speed is
reached, remove your feet from the pedals and the chosen vehicle speed
will be maintained.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
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:For information on electrical items such as fuses or relays, see the
Fuseschapter.
The load capacity of your vehicle is designated by weight not volume.
You may not necessarily be able to use all available space when loading
your vehicle or trailer.
Towing a trailer places extra load on the engine, transmission, axle,
brakes, tires, and suspension. Inspect these components before, during
and after towing.
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 tow bar 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. You can
find more information about proper trailer loading and setting your
vehicle up for towing underLoad limitin theLoad Carryingchapter.
You can also find information in theRV and Trailer Towing Guide
available at your authorized dealer.

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 turn
on 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 messageTRAILER SWAY
REDUCE SPEEDappears 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 theLoad
Carryingchapter for specific loading information.
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 feet
2(3.39 meters2) trailer frontal area for vehicles equipped
with the standard towing package.
•60.0 feet
2(5.57 meters2) trailer frontal area for vehicles 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.

When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park your vehicle, without the trailer, on a level surface.
2. Measure the height of the top of your vehicle’s front wheel opening
on the fender. This is H1.
3. Attach the trailer to your vehicle without the weight-distributing bars
connected.
4. Measure the height of 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 the front fender is approximately halfway between H1
and H2.
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.
Once 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.
Weight-distributing Hitch – Vehicles with 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.
Note:
If you do not move the loaded vehicle for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if you leave a trailer attached to the parked vehicle for long
periods. You must drive your vehicle in order to re-level the suspension.
When connecting a trailer to a vehicle with automatic leveling suspension
using a weight-distributing hitch, always use the following procedure:
1.
Load the interior of the vehicle to a weight similar to that which you
intend to carry when towing. This includes things such as passenger
weight and cargo.
2. Drive the vehicle for approximately 2 miles (3 kilometers) to re-level
the suspension.
3. Park your vehicle, without the trailer, on a level surface.
4. Measure the height to the top of your vehicle’s front wheel opening on
the fender. This is H1.

5. Attach the trailer to your vehicle without the weight-distributing bars
connected.
6. Make sure you securely attach and lock the trailer tongue to the hitch.
7. Install safety chains, lighting, and trailer brake controls as required by
law or the trailer manufacturer.
8. Drive the vehicle and trailer at 20–25 mph (32–40 km/h) for
approximately 2 miles (3 kilometers) to re-level the suspension.
9. Park your vehicle and trailer on a level surface.
10. Measure the height to the top of your vehicles front wheel opening on
the fender a second time. This is H2.
11. Install and adjust the tension in the weight distributing bars so that
the height of the front fender is approximately halfway between H1
and H2.
12. Check that the trailer is level or slightly nose down toward the vehicle.
If it is not, remove the trailer, adjust the ball height accordingly, and
repeat Steps 5 -11.
Once 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.
Safety Chains
Note:Do not attach safety chains to the bumper.
Always connect the trailer’s safety chains to the frame or hook retainers
of your vehicle hitch.
To connect the trailer’s safety chains, cross the chains under the trailer
tongue and allow enough slack for turning tight corners. Do not allow the
chains to drag on the ground.
Trailer Brakes
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not have
enough braking power and your chances of having a collision greatly
increase.
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if you install them properly and adjust them to the manufacturer’s
specifications. The trailer brakes must meet local and federal regulations.

Trailer Lamps
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 kilometers).
•Do not make full-throttle starts.
•Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
•When stopped in congested or heavy traffic during hot weather, place
the gearshift in positionPto aid engine and transmission cooling and
to help air conditioning performance.
•Turn off the speed control with heavy loads or in hilly terrain. The
speed control may turn off automatically when you are towing on
long, steep grades.
•Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
•If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when towing. This provides engine braking
and helps eliminate excessive transmission shifting for optimum fuel
economy and transmission cooling.
•If your vehicle is equipped with AdvanceTrac™ with RSC, this system
may turn on during typical cornering maneuvers with a heavily loaded
trailer. This is normal. Turning the corner at a slower speed while
towing may reduce this tendency.
