If your vehicle has been involved in a
crash, have the fuel system checked.
Failure to follow this instruction
could result in fire, personal injury or death. Note:
When you try to restart your vehicle
after a fuel shutoff, the vehicle makes sure
that various systems are safe to restart.
Once the vehicle determines the systems
are safe, then the vehicle allows you to
restart.
Note: In the event that your vehicle does
not restart after your third attempt, contact
a qualified technician.
The fuel pump shutoff stops the flow of
fuel to the engine in the event of a
moderate to severe crash. Not every
impact causes a shutoff.

CHANGING THE 12V BATTERY
WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. The Ford GT uses a lithium Ion battery.
The battery is located inside the right front
fender. For battery maintenance or
replacement, contact an authorized dealer.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
Note:
If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.
Because your vehicle ’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle. 5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 212). Reset the radio
station presets. See Audio System
(page 212).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
Battery Charger and Maintainer
If you plan to have your GT parked for more
than two weeks without driving it, connect
the battery charger and maintainer
provided. This charger connects simply to
the jump start(+) and (-) posts as shown
in the illustration below.
168
Ford GT (CGX), enUSA, Edition date: 201711, First Printing Maintenance

1. Connect the positive (+) red cable to
the positive (B) post.
2. Connect the negative (-) black cable to the negative (A) post.
The battery charger and maintainer
charges the battery to a full charge and
then monitor the charge as the car sits. If
the battery charge level drops, the
maintainer turns on to keep the battery
fully charged. You can keep the car stored
with the charger and maintainer attached.
For further information on the charger, see
the instructions provided with the charger.
Note: If the battery state of charge has
dropped below 10.5 volts, the battery will
have gone into its under voltage protection
mode. If this has occurred, connect the
charger and press the reset button on the
charger for 10 seconds. this will wake up the
battery to allow it to receive a charge.
Note: The GT battery charger and
maintainer is designed for the Lithium
battery used on Ford GT. Use only this
device. A charger designed for a lead acid
battery may damage the lithium battery in
your GT. 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 the electrical systems to protect
the battery.
Use the charger to bring the battery back
to full charge.
Electrical Accessory Installation
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.
CHECKING THE WIPER
