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 will light 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
charging circuit of the alternator. Please
contact the nearest BMW center.
If the V-belt is defective, do not
continue driving. The engine could
be damaged due to overheating. If the
V-belt is defective, increased steering
effort is also required.

<

Engine oil pressure


l


Stop the vehicle immediately
and switch off the engine. Check
the engine oil level and refill as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving, otherwise,
the engine could be damaged
because of inadequate lubrication.

<
Tire Pressure Control (RDC) l
In addition, an acoustic signal
will go off: 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 85.
Brake warning lamp 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 122 and 138.

If pointed or sharp-edged objects
could hit the rear window while
driving, be sure to provide protection
around all edges, otherwise, the
heating conductors for the rear window
could be damaged.<463de051
Luggage strapsUse the retaining straps on the cargo
area floor to secure smaller items of
luggage.
Movement is reduced when objects are
placed on the straps.
To attach the luggage nets
* or elastic
straps in order to keep luggage
securely in place, you will find lashing
eyes on the inside corners of the
luggage compartment.
Refer also to "Cargo loading" on
page 110.

The side rotary dials allow you to
open and close the air supply through
an infinitely-variable range, while the
levers change the airflow direction.
The center rotary dial controls the
temperature of the air as it flows out.

Air conditionerAir supply
You can select fan speeds
from 1 to 4. The greater the air
supply, the more effective the
heating and ventilation are. In
position 0, the fan and the heater are
switched off. By using position 0, you
can totally block the interior ventilation
outlets 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 90).
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 70.
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.
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 the
recirculated air off and increase the air
supply as required.<

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 for 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 stops.
You can reactivate the system by
pressing any button of the automatic
climate control.
Defrost windows and remove
condensation
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.
Use the button to switch the air condi-
tioner off when outside air temperatures
are 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, that then exits under the vehicle.

are thus normal.<
Automatic recirculated air control
(AUC)
You can respond to unpleasant
external odors by temporarily
blocking the outside air. The system
then recirculates 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. When the rear window defroster
is turned on, the indicator lamp
comes on; refer to page 70.

Draft-free ventilation You can adjust the blower controls for
the upper body area to select the
optimum airflow rates and directions for
your personal comfort:
Use rotary dials 1 to open and close the
air outlets through an infinitely-variable
range. You can adjust the direction of
the airflow with rotary dial 2.
Set the air outlets so that the air flows
past you and is not directed straight
at you.
The rotary dial 3 allows you to mix the air
from the outlets for the upper body with
more or less cool air.460de040
Microfilter/Activated-charcoal
filterThe microfilter has been installed to
catch any incoming dust and pollen.
The activated-charcoal filter provides
additional protection by filtering
gaseous pollutants from the outside air.
Your BMW center can replace the
combined filter as a standard part of
your scheduled maintenance.
A substantial reduction in air flow indi-
cates that the filter needs to be
replaced early.
For additional information on filter
removal, refer to page 165.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 buttons.
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.

Disc brakesDriving notesWhen driving in wet conditions and in
heavy rain, it is effective to apply light
pressure to the brakes every few miles
or kilometers. Watch traffic conditions
to ensure that this maneuver does not
endanger other drivers. The heat which
is generated by the brake applications
helps to dry the brake pads and discs.
Maximum braking force is obtained
while the wheels are not locked, but
rather when they are still barely turning
immediately prior to locking. ABS main-
tains this state automatically. If the ABS
fails, you should revert to the staggered
braking technique (refer to page 122).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible
impairment of the braking effect.
The braking effect of the engine can be
further increased by downshifting, into
first gear, if necessary. In the manual
mode of the automatic transmission,
you can also downshift into first gear.
Refer to page 66.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic),
releasing the pedal, and then repeating
the application (staggered braking). The
cooling phases between active braking
intervals prevent the brakes from over-
heating, thus ensuring that full braking
capacity remains available at all times.
Do not allow the vehicle to coast
when the clutch is depressed or
by shifting into neutral while moving. Do
not drive when the engine is switched
off. The engine provides no braking
control when the clutch is depressed or
the transmission is in "Neutral" and
there is no power-assist for the brakes
when the engine is shut off.
BMW 325xi: have brake inspections
performed at a BMW center only. If you
do not, parts of the four-wheel drive
system could be damaged.
Do not allow floor mats, carpets or any
other objects to protrude into the area
around the brake pedal, the clutch or
the accelerator which could obstruct
their freedom of movement.<
