Charging the Battery

CHARGING THE BATTERY:

Charge the battery in the vehicle only when the engine is not running.

WARNING! Before doing any work on the electrical system be sure to unclamp the cable from the battery's negative terminal. Failure to do so can result in short-circuits, a fire or personal injury.

If the vehicle is to be parked longer than four weeks, disconnect the battery from the vehicle's electrical system by disconnecting the negative terminal cable and then recharge using a suitable charging device.

If you intend to store your car for longer than twelve weeks: Remove the battery, charge it and store it in a cool (but frost- and dust-free) room. Every three months and before reinstalling the battery, have it recharged. If it is not recharged, it will not be serviceable. Every time the battery is discharged, especially over extended periods, its service life is reduced.

CAUTION: Return used batteries to a recycling center or your BMW center. Maintain the battery in an upright position for transport and storage. Secure the battery to prevent it from tilting during transport.

NOTE: Storage periods during which the battery is disconnected are not taken into consideration by the Service Interval Display for changing the brake fluid. For this reason, be sure that the brake fluid is changed every two years, regardless of the information displayed.
