Indicator and warning lamps Technology that monitors itself Many 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 l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the
charging circuit of the alternator. Please
contact the nearest BMW center.
If the V-belt is defective, do not
continue driving. If you do so, the
engine could be damaged due to over-
heating. If the V-belt is defective,
increased steering effort is also
required.<
Engine oil pressure
l
Stop the vehicle and switch off
the engine immediately. Check
the engine oil and top off as required. If
the oil level is correct, please contact
the nearest BMW center.
Do not continue driving. If you do
so, the engine could be damaged
because of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, an acoustic signal is
sounded: a tire failure has
occurred. Reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
brake applications. Do not oversteer.
For additional information, refer to
page 86.
Brake hydraulic system l
If the lamp comes on when the
parking brake is not engaged:
Check the brake fluid level. Before
driving further, be sure to read the
notes on pages 121 and 143.

dian models.

Air conditioner1 Air onto the windshield and onto the
side windows
2 Air for the upper body area
The side rotary dials allow you to
open and close the air supply through
an infinitely-variable range, while the
levers change the air flow direction.
The center rotary dial controls the
temperature of the air as it flows out.
Refer to page 94
3 Air for the front footwell
There are also vent outlets for the
footwell in the rear as well

Air conditionerAir supply
You can select blower speeds
from 1 to 4. The heating and
ventilation become more and
more effective as the air
supply settings are increased. In posi-
tion 0, the fan and the heater are
switched off. By using position 0, you
can totally block the air supply by
pressing the button for the recirculated-
air mode.
Temperature
In order to increase the
temperature of the passenger
compartment, turn it to the
right (red). Temperature regu-
lation will keep the interior temperature
you have selected constant.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . You can also
make all intermediate settings. In the
setting, there is a low flow of air onto
the windows to keep them free of
condensation. The "6 o'clock" setting is
recommended as a normal setting (refer
also to the illustration and overview on
page 92).
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 71.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed 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 the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). 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.<
Recirculated-air mode
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates the air already within
the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required.<

Automatic climate control
*
Air supply

By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control of the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button of the automatic
climate control.
To defrost the windshield and
side windows
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and Ð depending on the
temperature setting Ð rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Switch off the air conditioner at outside
temperatures below approx. 41 7
(+5 6). 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 recirculated air control
(AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the air flow from
the outside. The system then recircu-
lates the air already within the vehicle.
By repeated actuation of the button,
you can select one of three different
operation modes.
>Indicator lamps off: fresh 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 flow as
required. The system then recircu-
lates the air already within the
vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply as
required.<

Seat heating
*
Roller sun blind

The seat cushion and backrest can
be heated with the ignition key in posi-
tion 2.
You can call up different heating modes
by repeatedly pressing the keys.
When the three indicator lamps are illu-
minated, the highest heating mode is
activated. One lamp indicates the
lowest heating mode. The temperature
is regulated with a thermostat in each
mode.
You can also switch the higher heating
modes off directly:
Press and hold the button slightly
longer.460us285
To actuate, press the button briefly with
the ignition key in position 2.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.460us286
