Temperature adjustment
You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear in the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains
this temperature, regardless of the season.
Defrost windows and clear them of
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
To adjust air supply manually
You can adjust the air supply by
turning. The automatic air
supply control is operational
whenever you see your selec-
tion represented by a bar in the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic
air supply mode with the AUTO button.
Air conditioner operation
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
Select this program to obtain
maximum cooling as quickly as
possible.
The temperature display reverts
to 61 7 (16 6) while the system switches
to the recirculated-air mode and starts to
provide maximum air supply through the instrument panel outlets only. For this
reason you should ensure that these
outlets are open before selecting this
program.
Outside air/AUC Automatic recircu-
lated-air control/Recirculated air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the flow of outside air.
The system then recirculates the air
currently within the vehicle. AUC executes
this function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows into
the vehicle
>Left-hand indicator lamp on Ð AUC
mode: the system detects pollutants in the
outside air and responds by deactivating
the outside air supply when required. The
system then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to alter-
nate between its outside-air and
recirculated-air modes
>Right-hand indicator lamp on Ð Recircu-
lated-air mode: the supply of outside air
into the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle is
stopped at a school to pick up a
child.
You can adjust the automatic climate
control's settings when the ignition lock is
in the radio mode. The system blows

A congenial climate
102 heated air into the interior in accordance
with the selected distribution pattern while
the ignition is off.
Provided that the engine has warmed
to its normal operating temperature
and the battery is charged, you can use this
function for up to 15 minutes after
switching off the ignition. The LED within
the button lights up to confirm compliance
with both of these conditions.<
Front ventilation You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the outlets through an infinitely-
variable range, while the serrated dials 2
allow you to adjust the airflow direction. 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 ventilationSet the vent outlets so that the air flows
past you and is not directed straight at you.
The airflow temperatures for the indi-
vidual upper-body vent outlets can be
adjusted separately in the Control Display,
refer to page 104.
When the vent outlets are completely
closed, the vents at the top of the cockpit
provide indirect ventilation for the
passenger compartment.<
Ventilation for storage compartment
in front armrest You can use the serrated dial in the storage
compartment to open and close the vent
outlet.
Depending upon the temperatures
selected at the rear dials, high
temperatures may occur in the storage
compartment. Close the vent as required.< Rear ventilation The serrated dials 1 allow you to open and
close the ventilation outlets through an infi-
nitely-variable range.
You can adjust the airflow direction using
the levers 2
The serrated dials 3
* control the amount of
cooled air in the flow from the vent outlets:
Turn toward blue sector Ð colder
Turn toward red sector Ð warmer
This function allows you to make minor
adjustments for maximum comfort while
also letting you vary temperatures within
the storage compartment.

Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
BMW engines are designed to
operate without additives, and their
use could even lead to damage in some
cases. This also applies to the automatic
transmission, the differential and the power
steering system.<
Recommendation: have your oil changed at
your BMW center.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oil, grease, etc., well out of
the reach of children; always observe all
warning labels on the containers.<
Please observe all environmental-
protection rules and regulations when
disposing of used oil.< Specified engine oils The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High
Performance Synthetic Oil, you can add
small amounts of another synthetic oil
between oil changes. Use only oils with the
API SH specification or higher. Ask your BMW center for details
concerning the specific BMW High
Performance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
Viscosity ratingsViscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.
To avoid the possibility of damage later on,
never use anything other than factory-
approved, nitrite and amino-free extended-
duty antifreeze with corrosion inhibitor.
Your BMW center is familiar with the official
specifications.
Antifreeze and anticorrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Extended-duty antifreeze with corrosion
inhibitor contains ethylene glycol Ð a flam-
mable substance. For this reason, do not
spill antifreeze with corrosion inhibitor on
hot engine parts. It could ignite and cause
serious burns.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used
extended-duty antifreeze with corrosion
inhibitor.<
