Indicator and warning lampsTechnology that monitors itselfMany of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "l" are tested for
proper functioning whenever the igni-
tion key is turned. They each light up
once for different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this below.
Red: stop immediately
Battery charge current l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the charg-
ing circuit of the alternator. Please con-
tact the nearest BMW center.
If the ribbed V-belt is defective, do
not continue driving. The engine
could be damaged due to overheating.
If the ribbed V-belt is defective, in-
creased steering effort is also re-
quired.<
Engine oil pressure l
Comes on while the engine is
running and the "STOP!ENGINE
OILPRESS" message appears in the
Check Control: stop vehicle immedi-
ately and switch off engine. Check level
of oil in engine, top up as required. If oil
level is correct: please contact the
nearest BMW center.
Do not continue driving. The en-
gine could be damaged because
of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, there is an acousti-
cal warning signal: a tire failure
has occurred. Reduce vehicle speed
immediately and stop the vehicle. Avoid
hard brake applications. Do not over-
steer. For additional information: refer
to page 103.
Parking brake
*,
brake hydraulic system l
Comes on when you engage the
parking brake. For additional informa-
tion: refer to page 70.
Comes on although the parking brake is
released: have the brake fluid level
checked. Before driving further, be
sure to read the notes on pages 146
and 168.
Also comes on with the message
"CHECK BRAKE PADS" in the Check
Control.

Air conditionerTips for a pleasant driving
experienceTemperature 6 is recommended for a
comfortable setting at 707 (226).
Turn the air distribution 7 to the
"6 o'clock" position. Adjust the air sup-
ply 8 to the center setting. Set the out-
lets 2 so that the air flows past you and
is not directed straight at you. Set the
rotary dial between the outlets 2 for the
upper body to a central position so that
cooler air helps prevent fatigue during
the journey.
The following description will lead you
through additional individual adjust-
ments.Temperature
The graduations on the dial
provide general reference val-
ues for the interior tempera-
ture. We recommend 707
(226) as a comfortable setting. When
you start the vehicle, this system ad-
justs the air to the selected temperature
as quickly as possible, and then main-
tains that temperature constantly.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . You can also
select all intermediate settings. In the
setting, there is a low flow of air onto
the windows to keep them free of con-
densation. The "6 o'clock" setting is
recommended for normal conditions
(refer to the illustration and overview on
page 108).
Air supply
You can adjust the air supply
over an infinitely-variable
range. The heating and venti-
lation become increasingly
effective as the air supply settings are
increased. In the "0" setting, the blower
and climate control are switched off
and the outside air supply is blocked.
Rear window defroster
When the rear window de-
froster is activated, the indi-
cator lamp comes on. The rear window
defroster switches off automatically.
Cooling
The air is cooled and dehu-
midified and – depending on
the temperature setting – warmed again
with the air conditioner system
switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Switch off the air conditioner at outside
temperatures below approx. 427
(56). This will help to prevent the
windows from fogging up.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<

Automatic climate control
*
Air supply
In the "AUTO" program, the
airflow is controlled automati-
cally. AUTO will appear in the display 9
(refer to the overview on page 114).
Use "+" and "– " to vary the airflow.
When your setting is displayed by bars,
the automatic airflow is switched off.
Automatic air distribution maintains its
setting. You can reactivate the auto-
matic airflow by pressing the "AUTO"
button.
When you press "– " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The out-
side air supply is closed. By pressing
any button of the automatic climate
control (except the "MAX" button 16),
you can switch the system back on.
To defrost windshield and
windows
This program quickly re-
moves ice and condensation
from the windshield and the side win-
dows.
Air conditioner
The air is cooled and dehu-
midified and – depending on
the temperature setting – warmed again
when the air conditioner system is
switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started.
Use the button to switch off the air con-
ditioner at outside temperatures below
approx. +417 (+56). This will help to
prevent the windows from fogging up.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
+41 7(+5 6).
The temperature display 9 jumps to
+61 7 (+16 6), the system switches
over to the recirculated-air mode, and
the air will only stream out of the venti-
lation grill with the maximum amount of
air flow. That is why you need to keep
these open if you select this program.
Automatic recirculated-air
control (AUC)
You can respond to unpleas-
ant external odors by tempo-
rarily stopping the flow of outside air.
The system then recirculates the air
currently within the vehicle. Press the
button repeatedly to run through the
following control sequence:
>Indicator lamps off: outside airflow
operational.

118n
Automatic climate control
*
>Left-hand indicator lamp on – AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The sys-
tem then recirculates the air currently
within the vehicle.
Depending on the air quality, the au-
tomatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle.
>Right-hand indicator lamp on: the
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multifunction steering
wheel with the recirculated-air button
(refer to page 25), you can also use it to
switch between "Off" and the recircu-
lated-air mode or AUC and the recircu-
lated-air mode.
If the windows should fog over in
the recirculated air mode, switch
the recirculated air mode off and in-
crease the air supply as required.<
Rear window defroster
When the rear window de-
froster is activated, the indica-
tor lamp comes on. The rear window
defroster switches off automatically.
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
control. In ignition key position 0, the
system automatically directs heated air
to the windshield, side windows and
footwells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately charged. The LED
on the button will light up when all con-
ditions have been met.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use rotary dial 1 to open and close the
airflow through an infinitely-variable
range. You can also use the levers 2 to
change the direction of the airflow.
Set the outlets so that the air flows past
you and does not flow directly onto you.
Rotary dial 3 allows you to adjust the
airflow from these outlets by adding
heat or cooling as desired:
Turn toward blue – colder.
Turn toward red – warmer.390de051
