242 Maintenance WARNING: Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling. Your vehicle is equipped with a Motorcraft® maintenance-free battery which normally does not require additional water during its life of service. Note: If your battery has a cover or a shield, make sure it is reinstalled after the battery has been cleaned or replaced. For longer, trouble-free operation, keep the top of the battery clean and dry. Also, make certain the battery cables are always tightly fastened to the battery terminals. If you see any corrosion 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. It is recommended that the negative battery cable terminal be disconnected from the battery if you plan to store your vehicle for an extended period of time. Battery Relearn 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 begin this process: 1. With the vehicle at a complete stop, set the parking brake. 2. Put the gearshift in position P (automatic transmission) or the neutral position (manual transmission), turn off all accessories and start the engine. 3. Run the engine until it reaches normal operating temperature. 4. Allow the engine to idle for at least one minute. 5. Turn the A/C on and allow the engine to idle for at least one minute. 6. Drive the vehicle to complete the relearning process. • The vehicle may need to be driven 10 mi (16 km) or more to relearn the idle and fuel trim strategy. • Note: If you do not allow the engine to relearn its idle trim, the idle quality of your vehicle may be adversely affected until the idle trim is eventually relearned. 2013 05+ Mustang (197) Owners Guide gf, 3rd Printing USA (fus)

WARNING:
Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Your vehicle is equipped with a Motorcraft® maintenance-free battery
which normally does not require additional water during its life of
service.
Note:
If your battery has a cover or a shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion 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.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time.
Battery Relearn
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 begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in position P (automatic transmission) or the neutral
position (manual transmission), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
The vehicle may need to be driven 10 mi (16 km) or more to relearn
the idle and fuel trim strategy.
Note:
If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
