>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

Microfilter, activated-charcoal
filterThe 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 scheduled mainte-
nance.
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.
The highest heating mode is on when
the three indicator lamps are lit; one
lamp is lit for lowest heating. Tempera-
ture regulation in each mode is with a
thermostat.
You can also switch the higher heating
modes off directly:
Press the key and hold it slightly longer.

To activate and cancel the steering
wheel heater, press the button (arrow)
with the ignition key in position 2.
The lamp within the button lights up
when the steering wheel heater is in
operation.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 25).390de656

the ignition key in position 1 or 2.Roller sun blinds for rear side

This system allows you to ventilate the
interior and lower its temperature, using
the blower of the automatic climate
control.
The independent ventilation system is
operated via the Multi-Information Dis-
play (MID) – refer to page 94 – or the
onboard monitor. Refer to the separate
Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also turn it on and
off directly. Since the system uses a
substantial amount of electrical current,
you should not activate it twice in suc-
cession without allowing the battery to
be recharged in normal operation
between use.
When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above 607 (166), or by direct switch
activation. It cannot be switched on
when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vents
must be open for the system to oper-
ate.

Overview
151nTire replacement
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. BMW tests and approves
wheel/tire combinations. Refer to
page 153.
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades. <
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1g) times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
Traction
The traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of as-
phalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and does
not include acceleration, cornering, hy-
droplaning, or peak traction character-
istics. <
Temperature
The temperature grades are A (the
highest), B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or ex-
cessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure. <
