Getting Roadside Assistance
To fully assist you should you have a
vehicle concern, Ford Motor Company
offers a complimentary roadside
assistance program. This program is
separate from the New Vehicle Limited
Warranty.
The service is available:
•
24 hours a day, seven days a week.
• For the coverage period supplied with
your vehicle.
Roadside Assistance covers:
• A flat tire change with a good spare
(except vehicles supplied with a tire
inflation kit).
• Battery jump start.
• Lock-out assistance (key replacement
cost is the customer's responsibility).
• Fuel delivery — independent service
contractors, if not prohibited by state,
local or municipal law, shall deliver up
to 2 gal (8 L) of gasoline or 5 gal (20 L)
of diesel fuel to a disabled vehicle.
Roadside Assistance limits fuel delivery
service to two no-charge occurrences
within a 12-month period.
• Winch out — available within 100 ft
(30 m) of a paved or county
maintained road, no recoveries. •
Towing — independent service
contractors, if not prohibited by state,
local or municipal law, shall tow Ford
eligible vehicles to an authorized dealer
within
35 mi (56 km) of the
disablement location or to the nearest
authorized dealer. If a member
requests a tow to an authorized dealer
that is more than
35 mi (56 km) from
the disablement location, the member
shall be responsible for any mileage
costs in excess of
35 mi (56 km).
• Roadside Assistance includes up to
$200 for a towed trailer if the disabled
eligible vehicle requires service at the
nearest authorized dealer. If the towing
vehicle is operational but the trailer is
not, then the trailer does not qualify for
any roadside services.

WARNING: Battery posts,
terminals and related accessories
contain lead and lead compounds,
chemicals known to the State of
California to cause cancer and
reproductive harm. Wash your hands
after handling
. 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 323).
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.
337
Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Maintenance

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.
Remove and Reinstall the Battery
To disconnect or remove the battery, do
the following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for
example lights and radio.
3. Wait a minimum of two minutes before
disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty. 4. Disconnect the negative battery cable
terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Power
Windows (page 96).
• Clock Settings.
• Pre-set radio stations.
Battery Disposal Make sure that you dispose of
old batteries in an
environmentally friendly way.
Seek advice from your local authority
about recycling old batteries.
