Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior
temperature.
Detailed setting options are described for
you below.
Automatic air distribution and supply
The AUTO program assumes the
adjustment of the air distribution
and air supply for you and in addi-
tion adapts the temperature to
external influences, summer or winter, to
meet preferences you can specify.
In the AUTO program, the air conditioning
mode is also turned on at the same time.
The AUTO program functions only to
a limited extent when the convertible
top is open.<
Individual air distribution
You yourself can direct airflow
onto the windows , toward the
upper body and into the foot-
well . The arrow lights up. The
automatic air supply remains unchanged.
All intermediate settings are possible. By
pressing the AUTO button, you can reacti-
vate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a
general figure intended for refer-
ence purposes. When you start
the vehicle, the system ensures that the
selected temperature is reached as quickly
as possible, regardless of the season. It
then maintains this temperature.
Air supply/blower
You can set the blower through
an infinitely variable range of
speeds. This shuts off the auto-
matic air supply. The arrow lights
up. The automatic air distribution remains
unchanged. You can reactivate the auto-
matic air supply by pressing the AUTO but-
ton.When you turn the rotary control toward
zero: the blower, heating and air condi-
tioner are switched off, and the air supply is
stopped. You can reactivate the system by
turning the control toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
Above an outside temperature of
417/+56 and with the engine
running, you achieve a maximum
cooling effect as quickly as possi-
ble. At the same time, the air conditioning is
turned on.
The temperature is set to the lowest possi-
ble value. The system switches into the
recirculated air mode and air flows at max-
imum blower speed from the air outlets
only. Therefore, the air outlets must always
be open when you select this program.
Air conditioning
The air is cooled and dehumidi-
fied and, depending on the tem-
perature setting, rewarmed.
Depending on the weather, the
windshield may fog over briefly when the
engine is started.
The air conditioning system is automati-
cally switched on when you use the AUTO
program.
Condensation forms during operation
of the air conditioning system, which
then exits under the vehicle. Traces of con-
densed water on the ground underneath
the vehicle are thus normal.<

In the engine compartment
84 The oil volume between the two marks on
the dipstick corresponds to approx.
1.1 quarts/1 liter. Do not fill beyond the
upper mark on the dipstick. Excess oil will
damage the engine.
Adding engine oil
While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.
BMW engines are designed to oper-
ate without oil additives; the use of
additives could even lead to damage in
some cases. This also applies to manual
and automatic transmissions and to the dif-
ferential.<
Continuous exposure to used oil has
caused cancer in laboratory tests. For
this reason, thoroughly wash any areas of
skin that come into contact with oil using
soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and the
information on the containers.<
Comply with the applicable environ-
mental laws regulating the disposal of
used oil.<
Approved engine oils
The quality of the engine oil is extremely
important for the function and life of an
engine. Based on extensive testing, BMW
has approved certain grades of engine oil.
Use approved High Performance Synthetic
Oil.
If you are unable to obtain an approved
High Performance Synthetic Oil, you may use small volumes of other synthetic oils for
topping up between oil changes. Use only
oils with the specification API SH or higher.
Ask your BMW center for details con-
cerning the specific High Perfor-
mance Synthetic Oil or synthetic oils that
have been approved.<
You can also call BMW of North America
toll-free at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain this
information.
Coolant
The yellow coolant indicator lamp
lights up:
The coolant level is too low: top up
as soon as possible.
Do not add coolant to the cooling sys-
tem when the engine is hot. If you do,
escaping coolant can cause burns.
Antifreeze and anti-corrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location inaccessible to children.
Antifreeze and anti-corrosion agents are
flammable. For this reason, do not spill
them on hot engine parts. They could ignite
and cause burns. Comply with the instruc-
tions on the containers.<
Checking the coolant level
Correct coolant level when the engine is
cold, approx. 687/206:
1.Open the cap of the expansion tank by
turning it slightly counterclockwise to
