Battery Care
If your X3 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 SAV could
result in short term starting problems and in the
long term could damage the battery. 
In case the SAV 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 SAV center regarding bat-  tery 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 SAV center for 
further guidance and information.
Corrosion Protection
Extensive corrosion protection measures imple-
mented by BMW now make it possible to offer a
12-year limited mileage anti-corrosion warranty
against rust perforation on your SAV provided
that the SAV is maintained in accordance with
the provisions of the New SAV Limited Warranty
as outlined in the Warranty Section of this State-
ment (page 29). 
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
outside.  All floor panels receive a resilient coating of PVC 
for maximum protection against damage due to
stones, etc. 
Corrosion protection materials tested over many 
years are applied to the surfaces of cavities and
to the entire underside of the vehicle during and
after assembly. 
Requirements for maintaining the twelve-year 
unlimited mileage anti-corrosion warranty are
outlined in the Warranty Section of this State-
ment (page 31).
Restoring corrosion protection
Please take care that anti-corrosion material is
replaced when your car is repaired after body or
chassis damage. 
BMW will not accept any liability for any parts 
and accessories not approved by BMW.
Underbody maintenance
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)
will occur. 
Your BMW SAV center will do this anti-corrosion 
service for you.
WARNING
WARNING: 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.
