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 conditions before
your vehicle will drive properly. To begin this
process:
1. Set your parking brake.
2. Put the gearshift in P (Park), turn off all
accessories and start the engine.
3. Let the engine idle for at least one minute.
4. The relearning process will automatically
complete as you drive the vehicle.
²If you do not allow the engine to relearn its idle,
the idle quality of your vehicle may be adversely
affected until the idle is eventually relearned.
²If 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.
²Always dispose of
automotive batteries
in a responsible
manner. Follow your
local authorized
standards for
disposal. Call your
local authorized
authorized recycling center to find out more
about recycling automotive batteries.
