104 The air conditioner comes on automatically
when you select the AUTO program.
Temperature adjustment
You can turn to select the
desired temperatures for the
driver and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. 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.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection
represented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic
air supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and
starts to provide maximum air supply
through the vent outlets only. For this rea-
son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/
recirculated air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-
air mode: the supply of outside air into
the vehicle is permanently blocked.
The system then recirculates the air
currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<

Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle
is stopped at a school to pick
up a child.
You can adjust the automatic climate con-
trol's settings when the ignition lock is in
the radio mode. The system blows heated
air into the interior in accordance with the
selected distribution pattern while the igni-
tion is off.
Provided that the engine has warmed
to its normal operating temperature
and the battery is charged, you can use this
function for up to 15 minutes after switch-
ing off the ignition. The LED within the but-
ton lights up to confirm compliance with
both of these conditions.<

You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the outlets through an infinitely-
variable range, while the serrated dials 2
allow you to adjust the airflow direction.
Ventilation for cooling
Adjust the vents to direct the flow of cool
air in your direction, for instance, if the inte-
rior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you. You can also individually adjust the air
temperature of the air vents for the
upper body area in the Control Center,
refer to page 107.
If the ventilation grill is completely closed,
the vehicle interior is ventilated indirectly
by air vents on the upper side of the cock-
pit.<
Ventilation for storage compartment
in front armrest

Tire identification marks
Knowledge of the labeling on the side of
the tire makes it easier to identify and
choose the right tires.
Tire size
Speed rating
Q = up to 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines
of the U.S. Department of Transport.
DOT code:
Tire age
The tire's date of manufacture is indicated
on the sidewall:
DOT ... 3603 indicates that the tire was
manufactured in the 36th week of 2003.
Regardless of mileage or wear, BMW rec-
ommends that you replace all tires Ð includ-
ing the spare Ð after a maximum of 6 years, even though the tires may have a theoreti-
cal service life of up to 10 years.
Uniform Tire Quality Grading
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width.
For example:
Treadwear 200 Traction AA
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.<
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course.
For example, a tire graded 150 would wear
one and one-half Ð 1g Ð times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of their
use, however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics 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 specified govern-
ment 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 brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics.< e.g.
