Oxygen Sensor Service: The oxygen sensor deteriorates strictly on a mileage basis and must therefore
be replaced to maximize vehicle fuel economy and minimize exhaust pollution.
The mileage interval varies according to individual driving conditions and is determined by the service
interval indicator.

Battery Care
If your X5 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
twelve-year limited mileage anti-corrosion war-
ranty against rust perforation on your SAV pro-
vided that the SAV is maintained in accordance
with the provisions of the New SAV Limited War-
ranty 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 Booklet
(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
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.
