Automatic climate control Air conditioning
The air is cooled and
dehumidified and Ð
depending on the temperature setting Ð
warmed again when the air conditioning
is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. You can reduce con-
densation forming on the windows by
switching on the air conditioning.
Condensation forms in the air
condition system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
At outside temperatures
above roughly 41 7 (5 6)
this program furnishes maximum
cooling whenever the engine is running.
The temperature displays 9 jump to
60 7 (16 6), the system reverts to
operating in the recirculated-air mode
and maximum airflow emerges from the
vent outlets only. That is why you need
to keep these open if you select this
program.
Automatic recirculated-air control
You can respond to
unpleasant external odors
by temporarily excluding the flow of
outside air. The system then recircu-
lates the air currently within the vehicle.
By repeated actuations of the button,
you can select one of three different
operation modes.
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air cur-
rently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right indicator lamp on Ð recircu-
lated-air mode: the flow of external
air into the vehicle is permanently
blocked. The system then recirculates
the air currently within the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
it off and increase the air supply as
required.<
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Residual heating mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance). In
ignition key position 1, you can alter the
settings of the automatic climate con-
trol. With the ignition key in posi-tion 0,
the system automatically directs heated
air to the windshield, side windows and
footwells.
This function is available for oper-
ation when the outside tempera-
ture is below approx. 59 7 (15 6),
with the engine warm from recent oper-
ation and an adequate charge in the
battery. The LED on the button will light
up when all conditions have been
met.<

Engine oil CoolantSpecified engine oils The quality of the engine oil is
extremely important for the function
and service life of an engine. Based on
extensive testing, BMW approves only
certain grades of engine oil.
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 synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"special 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 information.
Viscosity ratings Viscosity is the oil flow rating as estab-
lished 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.
Do not add coolant to the cooling
system when the engine is hot.
If you attempt to do so, escaping
coolant can cause scalds. To avoid the
possibility of secondary damage, never
use anything other than factory-
approved, nitrite and amino-free
extended-duty antifreeze with corrosion
inhibitor. Your BMW center is familiar
with these specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original con-
tainers and in a location which is out of
reach of children. For this reason, do
not spill antifreeze with corrosion inhib-
itor on hot engine parts. It could ignite
and cause burns.<
