steering FORD EXPEDITION 2021 Repair Manual

When Towing a Trailer
•
Do not tow during the first 1,000 mi
(1,600 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C 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
slopes.
• 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 when towing may reduce
this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant if the axle is not already
filled with it. See
Capacities and
Specifications (page 392). •
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size,
tread-type, or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire
label or Safety Compliance label for
limitations when using these tires.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions and
reliability.

Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or another axle repair is
required.
TOWING THE VEHICLE ON
FOUR WHEELS
WARNING: If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 146).
Follow these guidelines if you have a need
for recreational towing, for example towing
your vehicle behind a motorhome. These
guidelines prevent damage to your
transmission.
Two-wheel Drive Vehicles
You cannot tow a two wheel drive vehicle
with any wheels on the ground as vehicle
or transmission damage may occur. You
must tow your vehicle with all four wheels
off the ground, for example when using a
car-hauling trailer.
Four-wheel Drive Vehicles Without 4x4
LOW
If your vehicle is not equipped with 4x4
Low, you cannot tow your vehicle with any
wheels on the ground or vehicle damage
may occur. You must tow your vehicle with
all four wheels off the ground, for example
when using a car-hauling trailer. Four-wheel Drive Vehicles With 4x4
LOW
You can only tow a
4X4 LOW equipped
four-wheel drive vehicle with all wheels on
the ground by placing the transfer case in
its neutral position and engaging the four
wheel down towing feature. Perform the
steps outlined in the following section after
positioning your vehicle behind the tow
vehicle and properly securing them
together.
Four-wheel-down Towing
Note: If completed successfully, the
information display shows
Neutral Tow
Enabled Leave Transmission in Neutral.
This indicates that your vehicle is safe to
tow with all wheels on the ground.
Note: If you do not see the message in the
information display, you must perform the
procedure again from the beginning.
Note: Make sure you properly secure your
vehicle to the tow vehicle.
Entering Four-wheel-down Towing
1. Start your vehicle.
2. Select
2H on the 4WD mode selector
switch.
3. For vehicles equipped with a console shifter, place the transmission in stay
in neutral mode.
See Automatic
Transmission (page 203). For vehicles
equipped with a column shifter, place
the transmission in neutral (N).
4. Once the transmission is in neutral (N)
or stay in neutral mode, switch the
engine off but leave the ignition in the
on position. The information display
shows a
Transmission Not in Park
message.

Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.

designed to fit the footwell of your
vehicle that does not obstruct the pedal
area. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Pedals that cannot
move freely can cause loss of vehicle
control and increase the risk of serious
personal injury. WARNING:
Secure the floor mat
to both retention devices so that it
cannot slip out of position and interfere
with the pedals. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING: Do not place additional

Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Committee (ILSAC).
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap. See Under Hood Overview (page 336).
Turn it counterclockwise and remove
it.
3. Add engine oil that meets our specifications. See
Capacities and
Specifications (page 392). You may
have to use a funnel to pour the engine
oil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage. Note:
Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.

Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 392).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. When Fail-Safe Mode Is Activated WARNING:
Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short period for the engine to cool.

1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the MIN and the MAX marks on the
reservoir.
Note: If the brake fluid level is between the
MIN
and the MAX marks on the reservoir, it
is acceptable.
Note: If the brake fluid level is below the
MIN
mark or above the MAX mark, have
your vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications. See
Capacities and
Specifications (page 392).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake
fluid. Change the brake fluid at the
specified intervals to prevent degraded
braking performance. For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
CHANGING THE 12V BATTERY
WARNING:
Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately.

Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
negative battery cable to maintain battery
charge for quick starting.
Battery Management System (If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some electrical systems to
protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
displays to alert you that battery
protection actions are active. These
messages are only for notification that an
action is taking place, and not intended to
indicate an electrical problem or that the
battery requires replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
may temporarily disable some electrical
systems. Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
ADJUSTING THE HEADLAMPS
