Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.

6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.
