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.

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. To begin this process:

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.
