Automatic climate control
*
Air supply
In the AUTO program, the
air flow is controlled auto-
matically. AUTO will appear in the
display 9 (refer to the overview on
page 106). 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 automatic air supply 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
outside air supply is closed. You can
switch the system back on by pressing
any button of the automatic climate
control.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.
Air conditioner
The air is cooled and
dehumidified 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 the air condi-
tioner off at outside temperatures
below approx. +41 7(+5 6). This will
help to prevent the windows from
fogging over.
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 drops to
+61 7 (+16 6), the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum amount of flow. That
is why you need to keep these open if
you select this program.

Automatic recirculated air
control (AUC)
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the airflow from the outside. 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.
>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
system then recirculates the air
currently 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-hand indicator lamp on: the
flow of external air into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a multifunction steering
wheel with the button for recirculated
air (refer to page 26), you can also use
this button to switch between "Off" and
the recirculated air mode or AUC and
the recirculated air mode.
If the windows fog over in the
recirculated air mode, switch the
recirculated air 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
automatically.
Residual heat 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. With the ignition key in posi-
tion 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. +59 7 (+15 6), the
engine is at operating temperature, and
the battery is adequately charged. The
LED on the button will light up when all
conditions have been met.<

Seat heating
*
TemperaturePassengers in the rear seating area can
adjust their own temperature for the air
outlets:
>Turn toward blue – colder.
>Turn toward red – warmer.
When you start the vehicle, this system
ensures that the selected temperature
is achieved as quickly as possible. It
then maintains this temperature,
regardless of the season.
A temperature adjustment is only
possible when the blower is
switched on (not in the "0" setting).< 530us 063
Microfilter, activated-charcoal
filter The microfilter removes dust and pollen
from the incoming air. The activated-
charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces this combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air
flow indicates that the filter must be
replaced before normal maintenance.
Front The seat cushion and backrest can be
heated when the ignition key is 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 the button and hold it slightly
longer.530us064

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, the catalytic
converter could respond by over-
heating, leading to serious damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle, and parking the
vehicle, take care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves,
etc.). Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. This is because: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
With ABS, you will achieve the shortest-
possible braking distances under all
given conditions (braking while driving
straight ahead or in curves, different
road surfaces).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help retain steering and maneu-
vering capability on all types of road
surfaces (asphalt, cement, dirt, wet
surfaces, snow and ice).
Braking with ABS The system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is inactive
again whenever the vehicle's speed
drops back below approx. 4 mph
(6 km/h).
To shorten the braking distance — espe-
cially on steep, poor road surfaces when
driving slowly straight ahead — the
system allows one or both front wheels
to lock for a short time. Nevertheless,
the vehicle still retains steering
response since this "poor road logic" is
deactivated again automatically as you
steer.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you

Disc brakes 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 which
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 which even extended
application will fail to cure.
For your own safety: use only
brake pads that BMW has
released for your particular 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.<
Driving notes When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles (kilometers). Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. 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 continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
(refer to page 142).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions is required. This avoids excessive
strain on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear.
When driving a vehicle with automatic
transmission, you can still downshift
into first gear. Refer to page 69.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), then
releasing the pedal, then repeating the
application. This staggered braking
technique allows the brakes to cool in
the intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine shut off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at
an BMW center only. If you do not,
parts of the four-wheel drive system
could be damaged. Never allow floor
mats, carpets or any other objects to
protrude into the area around the accel-
erator, clutch and brake pedals and
obstruct their 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 – above all else
– driving safety which 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 tire inflation pressures –
including the spare wheel – regu-
larly (refer to page 30), at least every
two weeks and before beginning a
longer trip. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately
resulting in an accident.<
Tire tread – Tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
Tread pattern depth should not be
allowed to go below 0.12 in (3 mm),
even though the legally specified
minimum tread pattern depth is only
0.063 in (1.6 mm). At a tread pattern
depth of 0.063 in (1.6 mm), tread wear
indicators (arrow) in the tread-groove
base indicate that the legally-permis-
sible wear limit has been reached.
Below 0.12 in (3 mm) tread pattern
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road. 390de331
Do not drive 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 leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate
flat tire or some other vehicle defect, as
can variations in normal vehicle
response, such as a pronounced
tendency to pull to the left or right.
Should this occur, respond by immedi-
ately reducing your speed and carefully
proceeding to the nearest BMW center
or professional tire center, or having the
vehicle towed in to have it and its tires
inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<
