For your own safety

Fuels

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight Ð that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent Ð will not void
the applicable warranties with respect to
defects in materials or workmanship. Field
experience has indicated significant differ-
ences in fuel quality Ð volatility, composi-
tion, additives, etc. Ð among gasolines
offered for sale in the United States and
Canada. The use of poor-quality fuels may
result in driveability, starting and stalling
problems, especially under certain environ-
mental conditions such as high ambient
temperature and high altitude.
Should you encounter driveability prob-
lems which you suspect could be related to
the fuel you are using, we recommend that
you respond by switching to a recognized
high-quality brand.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.

Maintenance and repair

Advanced technology, e. g. the use
of modern materials and high-per-
formance electronics, requires specially
adapted maintenance and repair methods.
Therefore, only have corresponding work
on your BMW carried out by a BMW center
or a workshop that works according to
BMW repair procedures with correspond-
ingly trained personnel. If work is carried
out improperly there is a danger of conse-
quential damage and the related safety
risks.

<



Parts and accessories

For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Genuine BMW
Parts, you simultaneously acquire the
assurance that they have been thoroughly
tested by BMW to ensure optimized perfor-
mance when installed on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for dam-
age resulting from installation of parts and
accessories not approved by BMW.
BMW cannot test every product made by
other manufacturers to verify if it can be
used on a BMW safely and without risk to
either the vehicle, its operation, or its occu-
pants.
Genuine BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW
centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones Ð including operation of
any portable phone from within the vehicle
without using an externally mounted
antenna Ð or transceiver equipment, for
instance, CBs, walkie-talkie, ham radio or
similar accessories, may cause extensive
damage to the vehicle, compromise its
safety, interfere with the vehicle's electrical
system or affect the validity of the BMW
Limited Warranty. See your BMW center for
additional information.

Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part.

even if the display does not yet indicate
that service is required, refer to page 197.
This same precaution applies to all of the
other service and maintenance operations

vals.<

ratings:

A congenial climate

program is deactivated.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen
from the incoming air. The activated-char-
coal filter provides additional protection by
filtering gaseous pollutants from the out-
side air. Your BMW center replaces this
combined filter as a standard part of your
scheduled maintenance.
You can select a display of more detailed
information in the Service Interval Display,
refer to page 81.

modes can be selected and adjusted sep-
arately on the left and right sides:

Adjusting cooling
You can also set the system to
provide the desired level of
cooling by turning. We recom-
mend setting the system for
moderate cooling. When you
start the vehicle, this system ensures that
the selected setting is achieved as quickly
as possible. It then maintains this tempera-
ture, regardless of the season.
Adjusting air supply manually
You can adjust the air supply by
turning.
Maximum cooling
This program quickly provides
maximum cooling.
The system automatically switches to the
recirculated-air mode while a high-speed
stream of air simultaneously emerges from
the vent outlets. For this reason you should
ensure that these outlets are open before
selecting this program.

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimized safety. The ser-
vice schedule also includes operations
related to the vehicle's comfort and conve-
nience features, such as replacement of
the filters for the inside air. The aim is to
optimize maintenance with regard to
reducing the cost of running the vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
CBS is a more advanced version of the
Service Interval Display. Sensors combine
with highly-specialized algorithms to sup-
ply service information that reflects your
vehicle's actual operating conditions more
precisely than ever before.
The system now furnishes individual dis-
plays of the times remaining until the dead-
lines for specific service operations as well
as official state inspections:
>Engine oil
>Brakes: separate for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs >Vehicle check
>Coolant
>Official state inspections.
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's key, your BMW
Service Advisor is able to suggest precisely
the right array of service procedures for
your own individual vehicle.
By letting you define a service and main-
tenance regimen that reflects your own
individual requirements, Condition Based
Service builds the basis for trouble-free
driving.
You can find more detailed information
on the Service Interval Display on page 81.
