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. As the engine
is warming up, complete the following:
Reset the clock. See Audio System
(page 218). Reset the radio station
presets. See Audio System (page 218).
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 or in
storage for more than two weeks without
driving it, connect the Li-Ion compatible
battery charger and maintainer provided.
There are two methods to connect the
charger: Method 1: Rear Hatch Storage
Compartment Power Point
Your Ford GT has a 12V power point in the
rear hatch storage area that allows you to
conveniently plug in to charge and
maintain your battery.
Note:
You can only the use the hatch
storage power point for battery charging.
The one inside the passenger compartment
on the side of the center console will not
work for this purpose. 1. Locate and open the cap covering the
power point.
2. Insert the provided charger plug in to the power point.
3. Connect the charger to the wall socket.
4. Disconnect the charger from the wall socket before disconnecting the cigar
plug.
Method 2: Under Hood Jump Start
Posts
You can also connect the battery charger
to the posts underneath the front hood for
jump starting the vehicle. The charger
connects simply to the jump start positive
(+) and negative (-) posts as shown in the
following illustration.
