Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause damage to the electric motor.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the
coolant and may cause damage to the
electric motor.
Coolant Change
Change the coolant at specific mileage
intervals listed in the scheduled
maintenance information. Add prediluted
coolant approved to the correct
specification. See Cooling System
Capacity and Specification (page 344).
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See
Scheduled
Maintenance (page 390).
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
12V BATTERY
CHANGING THE 12V BATTERY
If the 12 volt battery needs servicing, see
your authorized dealer.
CHARGING THE 12V BATTERY
Your vehicle has a high voltage to low
voltage energy transfer feature that keeps
the 12 volt battery charged by the high
voltage battery. If the 12 volt battery level
is low, the high voltage battery transfers
energy to the 12 volt battery when the
vehicle is off.

1. Park your vehicle on a level surface approximately 25 ft (7.6 m) away from
a vertical wall or screen.
2. Apply the parking brake.
3. Measure the height from the center of your headlamp to the ground.
Note: There may be an identifying mark on
the lens to help you locate the center of the
headlamp low beam light.
4. Mark a horizontal reference line on the
wall or screen that is a minimum of 8 ft
(2.4 m)
long.

PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all vehicles and their
components for reliable, regular driving.
Under various conditions, long-term
storage may lead to degraded
performance or failure unless you use
specific precautions to preserve vehicle
components.
General
•
Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents. Cooling system
•
Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery Systems
We recommend the following actions for
your vehicle:
• When storing your vehicle for greater
than 30 days the state of charge
should be approximately 50%.
Additionally we recommend
disconnecting the 12v battery which
will reduce system loads on the HV
battery.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.

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

Make sure to change your vehicle
’s fluids
at the specified intervals or in conjunction
with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems
during scheduled maintenance. It is critical
that systems are flushed only with new
fluid that is the same as that required to fill and operate the system or using our
approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.Check Every Month
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check Every Six Months
12V Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag and safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as necessary.
Multi-point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.
