270 Maintenance When the battery is disconnected or a new battery installed, the automatic transmission must relearn its adaptive strategy. As a result of this, the transmission may shift firmly when first driven. This operation is considered normal and will fully update transmission operation to its optimum shift feel. If the battery has been disconnected or a new battery has been installed, the clock and the preset radio stations must be reset once the battery is reconnected. Note: Always dispose of automotive batteries in a responsible manner. Follow your local authorized standards for disposal. Call your local authorized recycling center to find out more about recycling automotive batteries. 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 P (Park), 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 miles (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. If the battery has been disconnected or a new battery has been installed, the clock and radio settings must be reset once the battery is reconnected. 2013 MKX (mkx) Owners Guide gf, 3rd Printing USA (fus)
