Battery Care
If your X5 M or X6 M 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 your X5 M or X6 M 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 SAV 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 SAV center for
further guidance and information.
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 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 Booklet (page 19).
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.
For additional information on the 12-year
unlimited mileage anti-corrosion warranty, see
the Warranty Section of this Booklet (page 21).
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 on metal components.
