Maintenance and care 4. 5. 6. • Allow the engine to idle for at least one minute. Turn the A/C on and allow the engine to idle for at least one minute. Drive the vehicle to complete the relearning process. The vehicle may need to be driven 16 km (10 miles) or more to relearn the idle and fuel trim strategy. • 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. When the battery is disconnected or a new battery installed, the transmission must learn its adaptive strategy. As a result of this, the transmission may shift firmly. 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. • 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.
