Maintenance and Specifications 1. With the vehicle at a complete stop, set the parking brake. 2. Put the gearshift lever 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 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 relearn its adaptive strategy. As a result of this, the transmission may shift firmly. This operation is considered normal and will not affect function or durability of the transmission. Over time the adaptive learning process 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.
