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:
 consider using a proper trickle charger, fol-
lowing the charger manufacturer’s instruc-
tions, to maintain the battery’s state of
charge; or
 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
Statement (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 NA 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.
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.
