WARNING: Keep batteries out of reach of children. Batteries

contain sulfuric acid. Avoid contact with skin, eyes or clothing.

Shield your eyes when working near the battery to protect against

possible splashing of acid solution. In case of acid contact with skin or

eyes, flush immediately with water for a minimum of 15 minutes and

get prompt medical attention. If acid is swallowed, call a physician

immediately.

WARNING: Battery posts, terminals and related accessories

contain lead and lead compounds. Wash hands after handling.

Battery relearn

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 and fuel trim strategy for optimum driveability and

performance. Flexible fuel vehicles (FFV) must also relearn the ethanol

content of the fuel for optimum driveability and performance. To begin

this process:

1. With the vehicle at a complete stop, set the parking brake.

2. Put the gearshift 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. Release the parking brake. With your foot on the brake pedal and with

the A/C on, put the vehicle in D (Drive) and allow the engine to idle for

at least one minute.

7. Drive the vehicle to complete the relearning process.

• The vehicle may need to be driven 10 miles (16 km) or more to

relearn the idle and fuel trim strategy along with the ethanol content

for flexible fuel vehicles.

• 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.

• For flexible fuel vehicles, if you are operating on E85, you may

experience poor starts or an inability to start the engine and

driveability problems until the fuel trim and ethanol content have been

relearned.
