HOW DOES ALL-WHEEL DRIVE
WORK
The all-wheel drive system is designed to
continuously monitor and adjust power
delivery to the front and rear wheels to
optimize both traction and handling.
There is further information on driving in
unique driving conditions. See Driving
Hints (page 280). ALL-WHEEL DRIVE
PRECAUTIONS WARNING:
Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
ALL-WHEEL DRIVE
LIMITATIONS
The all-wheel drive system is not intended
for use with mismatched tires.
Different tire sizes between the front and
rear axles can cause system damage.

ELECTRIC POWER STEERING
PRECAUTIONS
WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the vehicle off. After at least 10
seconds, switch the vehicle on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle
manually nor will it cause damage to the
system. Normal steering and driving allows
the system to cool down and steering
assist returns to normal. Note:
There is no fluid reservoir to check or
fill.
ELECTRIC POWER STEERING
ADAPTIVE STEERING
Adaptive Learning
(If Equipped)
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the
brake system to help operate advanced
stability control and crash avoidance
systems.
Note: When the battery is disconnected or
a new battery is installed, you must drive
your vehicle a short distance before the
system relearns the strategy and reactivates
all systems.
Steering Tips
If the steering wanders or pulls, check for:
• An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds could also make the steering
wander or pull.

ELECTRIC VEHICLE
MAXIMIZING YOUR DRIVING
RANGE
Driving in Cold Weather
Keep your vehicle charged before heading
out into cold weather.
Use the heated seats and steering wheel
for comfort along with moderate cabin
temperature and fan settings to reduce
energy needed for climate control.
Preconditioning Your Vehicle
You can precondition your vehicle by using
departure and comfort settings to warm
or cool your cabin and the high voltage
battery when your vehicle is plugged in. By
using energy from your charging source
prior to your departure, battery
temperature can be managed for best
driving performance and less energy will
be needed for heating or cooling of the
cabin at the start of your drive. This helps
maximize your driving range. See Setting
the Charging Schedule and Preferences
(page 174).
Note: You can also access departure and
comfort settings using the FordPass App.
Note: Lower cabin temperature settings on
the climate control system results in better
trip range.
Parking Your Vehicle
At temperatures just above the freezing
point and lower, plug your vehicle in when
not in use to maintain high voltage battery
performance.
When possible park your vehicle under a
covered area or in a garage. This will help
to moderate temperatures which affect
performance of the high voltage battery
and require energy to heat or cool the
cabin. Driving Style
Range is reduced when driving aggressively
or at consistently high speeds. Aggressive
driving for extended periods could also
result in reducing your battery
’s efficiency
and lifespan. Use the trip application on
your touchscreen to see your driving scores.
See
Trip Data (page 124).
DRIVING THROUGH SHALLOW
WATER WARNING:
Do not attempt to
cross a deep or flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
Note: Driving through standing water can
cause vehicle damage.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the front
rocker area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction could
be limited. After driving through water and
as soon as it is safe to do so:

277).
CHECKING THE COOLANT WARNING:
Do not remove the
coolant reservoir cap when the vehicle
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. WARNING:
Do not put coolant in
the windshield washer reservoir. If
sprayed on the windshield, coolant could
make it difficult to see through the
windshield. WARNING:
Do not add coolant
further than the MAX mark.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Your vehicle has a battery cooling system
and a motor electrical cooling system. See
Under Hood Overview
(page 303). The
luggage compartment covers need to be
removed in order to access the reservoirs.
See
Installing and Removing the
Luggage Compartment Cover (page 277). When the electric motor is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 390).
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between
-29–-35°F (-34–-37°C).
Check coolant concentration using a
refractometer. We do not recommend the
use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant
It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the electric motor
cooling system. See
Cooling System
Capacity and Specification (page 344).
Do not mix different colors or types of
coolant in your vehicle. Mixing of coolants
or using an incorrect coolant may harm the
electric motor or cooling system
components and may cause damage that
the vehicle warranty may not cover.
Note: Automotive fluids are not
interchangeable.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the electric
motor cooling or heating systems.

2021 Mustang Mach-E (CGW) Canada/United States of America, Vehicles Built From: 07-06-2021, enUSA, Edition date: 202104, First-Printing Maintenance

Note:
If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water. See
Cooling System Capacity and
Specification (page 344). Using water that
has not been deionized could contribute to
deposit formation, corrosion and plugging
of the small cooling system passageways.
Note: Coolants marketed for all makes and
models might not meet our specifications
and could cause damage to the cooling
system. Resulting component damage
could void the vehicle warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Cooling
System Capacity and Specification
(page 344).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted coolant to bring the coolant
level to the correct level.
If you have to add more than
1.1 qt (1 L) of
coolant per month, have your vehicle
checked as soon as possible. Operating
your vehicle with a low level of coolant can
result in overheating and possible electric
motor damage. In case of emergency, you can add a large
amount of water without coolant in order
to reach a vehicle service location. In this
instance, have qualified personnel do the
following as soon as possible:
1. Drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with coolant.
Water alone, without coolant, can cause
damage from corrosion, overheating or
freezing.
Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant, as an approved recycling process
is not yet available.
Dispose of used coolant in an appropriate
manner. Follow your community's
regulations and standards for recycling and
disposing of automotive fluids.

USING THE TIRE SEALANT
AND INFLATOR KIT
Tips for use of the kit
To ensure safe operation of the kit:
• Before operating the kit, make sure
your vehicle is safely off the road and
away from moving traffic.
• Do not remove any foreign objects,
such as nails or screws, from the tire.
• Do not allow the compressor to
operate continuously for more than 15
minutes. This will help prevent the
compressor from overheating.
• Only use the kit when the ambient
temperature is between -22°F (-30°C)
and 158°F (70°C).
• Only use the sealing compound before
the use-by date. The use-by date is on
a label on the sealant canister and can
be seen through the rectangular
viewing window on the bottom of the
compressor. Check the use-by date
regularly and replace the canister when
the sealant expires.
Note: Sealant compound contains latex.
Use appropriate precautions to avoid any
allergic reactions. When inflation only is required
for a tire or other objects, the
selector must be in the Air
position.
What to do when a tire is punctured
A tire puncture within the tire's tread area
can be repaired in two stages with the kit. •
In the first stage, the tire will be
reinflated with a sealing compound
and air. After the tire has been inflated,
you will need to drive the vehicle a
short distance approximately
4 mi
(6 km) to distribute the sealant in the
tire.
• In the second stage, you will need to
check the tire pressure and adjust, if
necessary, to the vehicle's specified
tire inflation pressure.
First Stage: Reinflating the Tire
with sealing compound and air WARNING:
Do not stand directly
over the kit while inflating the tire. If you
notice any unusual bulges or
deformations in the tire's sidewall during
inflation, stop and call roadside
assistance. WARNING:
If the tire does not
inflate to the recommended tire pressure
within 15 minutes, stop and call roadside
assistance.
Park the vehicle in a safe, level and secure
area, away from moving traffic.
Turn the hazard lights on. Apply the parking
brake and power off the vehicle. Inspect
the flat tire for visible damage.
If a puncture is located in the tire sidewall,
stop and call roadside assistance.
1. Remove the valve cap from the tire valve.
2. Unwrap the dual purpose hose (black tube) from the back of the compressor
housing.
3. Fasten the hose to the tire valve by turning the connector clockwise.
Tighten the connection securely.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when
you sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
It is important that you have your vehicle
serviced at the proper times. These
intervals serve two purposes; first is to
maintain the reliability of your vehicle and
the second is to keep the cost of owning
your vehicle down.
It is your responsibility to have all
scheduled maintenance performed and to
make sure that the materials used meet
the specifications identified in this owner's
manual.
Failure to perform scheduled maintenance
and regularly inspect your vehicle may
result in vehicle damage not covered by
the vehicle Warranty.
Why Maintain Your Vehicle at Your
Dealership?
Our Genuine Replacement Parts
Dealerships stock our parts and our
authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed
at your dealership carry a nationwide
24-month or unlimited mile (kilometer)
parts and labor limited warranty.
If you do not use our authorized parts they
may not meet our specifications.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved
reliability, durability and resale value. To
maintain the proper performance of your
vehicle, make sure you have scheduled
maintenance performed at the designated
intervals.
It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.
We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.

parts engineered for your vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
