Tips for pleasant drivingUse the automatic system (switch on
AUTO button 7). Select an interior
temperature that is comfortable for
you Ð we recommend +72 7 (+22 6).
When the outside temperature is above
+41 7 (+5 6), you can also use the air
conditioner 12. This will dry the air as
well as preventing condensation on the
window surfaces Ð if there are passen-
gers with damp clothing, for example.
Set the outlets 2 so that the air flows
past you and is not directed straight at
you. Set the rotary dial between the air
outlets 2 for the upper body to a
medium position, since air that is some-
what cooler promotes driving without
fatigue.
Detailed setting options are described
for you in the following section.
Automatic air distribution
The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and
adapts the temperature to external
influences (summer, winter) to meet
preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is comfort-
able for you Ð we recommend +72 7
(+22 6). The selected temperature
and AUTO for the air flow appear in
the display 10 (refer to the overview on
page 96). Open the air outlets for the
upper body area. Switch on the air
conditioner in warm weather. The
maximum cooling capacity is achieved
when you set rotary dial 3 (refer to
page 100) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
You can direct air to flow onto the
windows , toward the upper body
and into the footwell .
Temperature
The figures in the display
provide a general indication of
interior temperature. We recommend
+72 7 (+22 6) as a comfortable
setting, whether the air conditioner is
operating or not. When you start the
vehicle, the system ensures that the
selected temperature is reached as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Set rotary dial 3 (refer to "Draft-free
ventilation" on page 100) to a medium
setting, since air that is somewhat
cooler promotes driving without fatigue.
You can use this setting for mixing air to
make minor comfort modifications.
You can set uncontrolled heater
output up to +90 7 (+32 6). At
+60 7 (+16 6), full cooling output is
available from an activated air condi-
tioner.<

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.
Traces of condensed water of this kind
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.

Antilock Brake System (ABS) Disc brakesDynamic Brake Control (DBC)*DBC is included in the DSC, refer to
information beginning on page 81.
If you step on the brake rapidly, this
system automatically produces
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the yellow warning lamp comes
on. Normal braking efficiency
and the anti-lock braking system are
still fully available.
Have the system checked and repaired
at your BMW center as soon as
possible.
Refer to the "Information for your
safety" covering the ABS system.
This information also generally applies
for DBC.<
Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
discs and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure that must
be exerted by the pads to clean the
discs by brake applications is not
reached.
If the brake discs are corroded, they will
tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate
non-approved brake pads to determine
if they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

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.<

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all
else Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check the tire inflation pressure Ð
for the space-saver spare tire or
spare tire Ð on a regular basis (refer to
page 28), at least twice a month, and
before starting out on any extended
trip. If this is not done, incorrect tire
pressures can cause driving instability
and tire damage, ultimately resulting in
an accident.<
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base indicate that the wear
limit Ð applicable by law throughout
Europe Ð has been reached. Below
0.12 in (3 mm) tread depth, there is an
increased risk of aquaplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road.390de331
Never continue driving on a
deflated (flat) tire. A flat tire greatly
impairs steering and braking response,
and can lead to complete loss of
control over the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading can lead to
overheating and increases the rate at
which damage develops inside the
tires. You could have a blowout as a
result.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
The same applies to irregularities
related to your usual driving style, such
as pulling hard to the left or right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed
carefully to the nearest BMW center or
professional tire center, or have the
vehicle towed in to have it and its tires
inspected.
Tire damage (up to and including
sudden and complete air loss) can
endanger the lives of both the vehicle
occupants and other road users.<
