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.

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.

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 129.DOT Quality GradesTreadwear
Traction AA A B C
Temperature A B C
All passenger car tires must
conform to Federal Safety
Requirements in addition to these
grades.< Tread wearThe tread wear 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.
TractionThe 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 asphalt
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,
hydroplaning, or peak traction charac-
teristics.< TemperatureThe 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
temperature 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 Motor Vehicle Safety Stan-
dard No. 109. Grades B and A repre-
sent 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, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure.< Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200 Traction AA
Temperature A
Do not use retreaded tires. Driving
safety may be impaired by their
use. This is due to the possible varia-
tions in casing structures and, in some
cases, to their extreme age, which can
lead to a decrease in their durability.<
