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 vehi-
cle could result in short term starting problems
and in the long term could damage the battery.
In case the car is not operated for more than four
weeks it is advisable to:
a. consider using a proper trickle charger, follow- ing the charger manufacturer’s instructions, to
maintain the battery’s state of charge; or
b. 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.
Extensive corrosion protection measures imple-
mented by BMW now make it possible to offer a
twelve-year limited 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 War-
ranty as outlined in the Warranty Section of this
Statement (page 35).
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,
trunk, doors and other body parts with metal
folds are coated with PVC and sealed from the
All floor panels receive a resilient coating of PVC
for maximum protection against damage due to
Corrosion protection materials tested over many
years are applied to the surfaces of cavities and
to the entire underside of the vehicle during and
Requirements for maintaining the twelve year
unlimited mileage anti-corrosion warranty are
outlined in the Warranty Section of this State-
ment (page 37).
Restoring corrosion protection
Please take care that anti-corrosion material is
replaced when your car is repaired after body or
BMW will not accept any liability for any parts
and accessories not approved by BMW.
The underbody has to be cleaned at least once a
year, in spring, with plain water in order to remove
mud, chemical sediments and other deposits. If
those materials are not removed, corrosion (rust)
Your BMW center will do this anti-corrosion ser-
vice for you.
Do not apply additional undercoating or rust-
proofing on or near the exhaust manifold, exhaust
pipes, catalytic converter or heat shields. During
driving, the substance used for undercoating could
overheat and cause a fire.
