If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. Flexible fuelvehicles (FFV) must also relearn theethanol content of the fuel for optimumdriveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 315). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 78).Reset the radio station presets. SeeAudio System (page 315).
6.Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km)to completely relearn the idle trim andfuel trim 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 fueltrim strategy.
Note:For flexible fuel vehicles, if you areoperating on E85, you may experience poorstarts or an inability to start the engine anddriveability problems until the fuel trim andethanol content have been relearned.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30days without recharging the battery, werecommend that you disconnect thebattery cables to maintain battery chargefor quick starting.
