WARNING: This vehicle may have
more than one battery. Removing the
battery cables from only one battery
does not disconnect your vehicle
electrical system. Make sure you
disconnect the battery cables from all
batteries when disconnecting power.
Failure to do so may cause serious
personal injury or property damage. WARNING:
For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.
The battery is in the engine compartment.
See
Under Hood Overview (page 234).
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
If the vehicle battery has a cover and vent
hose, make sure you correctly install it after
cleaning or replacing the battery.
For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present on the battery or terminals, remove
the cables from the terminals and clean
with a wire brush. You can neutralize the
acid with a solution of baking soda and
water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note: If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing. If you replace the battery make sure it
matches the electrical requirements of
your vehicle.
If you disconnect or replace the battery
and your vehicle has an automatic
transmission, it must relearn its adaptive
strategy. Because of this, the transmission
may shift firmly when first driven. This is
normal operation while the transmission
fully updates its operation to optimum
shift feel.
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.

•
Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
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.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting. Note:
It is necessary to reset memory
features if you disconnect the battery
cables.
Plugging in Your HYBRID
We recommend the following options for
your plug-in vehicle (PHEV) :
• Leave your vehicle plugged in. The 12
volt battery maintains power if left
plugged in. However, this periodically
uses electricity from the household
outlet.
• Connect a battery charger to your 12
volt battery and leave it on a
continuous, slow charge.
• Disconnect the 12 volt battery. If your
12 volt battery is located in the luggage
compartment, do not fully shut the
luggage compartment after
disconnecting the 12 volt battery. Only
leave the luggage compartment open
if your vehicle is stored in a locked
location.
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.

U.S. Department of
Transportation Tire quality
grades: The U.S. Department of
Transportation requires Ford
Motor Company to give you the
following information about tire
grades exactly as the government
has written it.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150
would wear 1 ½ times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction AA A B C WARNING:
The traction
grade assigned to this tire is
based on straight-ahead braking
traction tests, and does not
include acceleration, cornering,
hydroplaning or peak traction
characteristics. The traction grades, from highest
to lowest are AA, A, B, and C. The
grades represent the tire
’s ability
to stop on wet pavement as
measured under controlled
conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
Temperature A B C WARNING:
The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.
The temperature grades are A
(the highest), B and C,
representing the tire ’s resistance
to the generation of heat and its
ability to dissipate heat when
tested under controlled conditions
on a specified indoor laboratory
test wheel. Sustained high
temperature can cause the
material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden
tire failure. The grade C
corresponds to a level of
performance which all passenger
car tires must meet under the
270
Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Wheels and Tires

Inflate the winter tires to the same tire
pressures as those listed in the tire
pressures table. See Technical
Specifications (page 295). WARNING:
Snow tires must be the
same size, load index and speed rating
as those originally provided by Ford. Use
of any tire or wheel not recommended
by Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of
control, vehicle rollover, personal injury
and death. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
USING SNOW CHAINS WARNING:
Aggressive driving in
any road conditions can cause you to
lose control of your vehicle increasing
the risk of severe personal injury or
property damage. The traction control
activating is an indication that at least
some of the tires have exceeded their
ability to grip the road; this may lead to
an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. If you experience a severe
road event, slow down
. The tires on your vehicle could have
all-weather treads to provide traction in
rain and snow. In some climates you will
need to use snow tires and chains on your
vehicle in emergency situations or if
required by law.
Note:
The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• When possible, avoid fully loading your
vehicle.
• Chains could damage aluminum
wheels.
• Use ultra low profile cables, 10 mm or
less in dimension as measured on the
sidewall of your tire, with 235/55R 17,
235/50R18 and 255/40R19 on the rear
axle only.
• Do not use snow chains or cables with
265/40R19, 275/40R19 and
265/35R20 tires.
• Not all S-class snow chains or cables
meet these restrictions. Chains of this
size restriction will include a tensioning
device.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the front or the rear tires only.
• Do not exceed
30 mph (50 km/h) if
recommended by the chain
manufacturer while using snow chains.
• Install cables securely, verifying that
the cables do not touch any wiring,
brake lines or fuel lines.
