12 Volt Battery Care*

If your car is driven only for short distances of

less than 10 miles over a prolonged period of

time, without an occasional drive at highway

speeds, the engine’s charging system will not

maintain the battery. Insufficient use of the

vehicle could result in short term starting

problems and in the long term could damage the

battery.

In case your car is not operated for several weeks

it is advisable to:

䉯 consider using a proper trickle charger,

following the charger manufacturer’s

instructions, to maintain the battery’s state of

charge; or

䉯 consult your BMW center regarding battery

removal. Once removed, the battery must be

charged and stored in a cool, dry place where

it can be protected from freezing. If the battery

will be stored for over 3 months, it must be

recharged every 3 months, or else it will

become damaged and useless.

Please consult with your BMW center for further

guidance and information.

For the ActiveHybrid 750i and ActiveHybrid 750Li

the information above refers to the 12 volt

service battery and not the high-voltage battery.

Corrosion Protection

Extensive corrosion protection measures

implemented by BMW now make it possible to

offer a 12-year unlimited mileage anti-corrosion

warranty against rust perforation on your vehicle,

provided that the vehicle is maintained in

accordance with the provisions of the New

Vehicle Limited Warranty as outlined in the

Warranty Section of this Booklet (page 18).

The major degree of corrosion protection is due

to the electrophoretic dip painting process which

cathodically deposits paint particles on all body

parts, attracting paint particles into the minutest

cavities or seams. Body parts are designed to

provide optimum corrosion protection.

During manufacture, exterior body parts receive

an additional corrosion protection coat. Hood,
