2008 BMW 6 SERIES maintenance schedule

Climate
112 >Left LED on, recirculated-air mode: the
supply of outside air into the vehicle is shut
off continuously.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
1.Switch off the engine.
2.Turn to the right, refer to arrow.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>engine at operating temperature
>sufficient battery voltage
>at an outside temperature below 777/
256
With the ignition lock at radio readiness or
higher the interior temperature, the air volume
and the air distribution can be set.
Switching automatic climate control
on and off
1.Turn to the left to minimum air volume.
2.After approx. 1 second, turn to the left
again.
You switch on the system again by pressing any
button of the automatic climate control.
Ventilation
1Knurled wheels for smoothly opening and
closing vent outlets
2Levers for changing the airflow direction
Do not drop any foreign objects into the
vent outlets; otherwise, they could be cat-
apulted outwards and cause injuries.<
Ventilation for cooling
Adjust the vent outlets to direct the flow of cool
air in your direction, for instance, if the interior
has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows past
you and is not directed straight at you.
Microfilter/activated-charcoal filter
The microfilter removes dust and pollen from
the incoming air. The activated-charcoal filter
provides additional protection by filtering gas-
eous pollutants from the outside air. Your BMW
center replaces this combined filter as a stan-
dard part of your scheduled maintenance.
You can have more detailed information shown
on the Control Display, refer to page77.
Parked car ventilation
The concept
The parked car ventilation blows air into the
passenger compartment to lower interior tem-
peratures.
It is ready to use in the parked-car mode at any
outside temperature.

Fuel specifications
Never used leaded gasoline; it will perma-
nently damage the catalytic converter.
Do not use E85, i.e. fuel that consists of 85%
ethanol, or Flex Fuel. Otherwise permanent
damage to the engine and the fuel supply sys-
tem will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has demonstrated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels
containing up to and including 10 % ethanol or
other oxygenates with up to 2.8 % oxygen by
weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will
not void the applicable warranties with respect
to defects in materials or workmanship.
The use of poor-quality fuels may result in
problems relating to drivability and start-
ing, and to a tendency to stall, especially under
certain environmental conditions such as high
ambient temperature and high altitude.
Should you encounter drivability problems
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
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your 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 inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page77:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is set correctly, refer
to page83, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<
