Lugagge compartment lidTo opening from the insideIf the luggage compartment lid has not
been locked separately, you can open it
with this button in the footwell on the
driver's side when the vehicle is
stationary.
To closeThe handle recesses in the interior trim
panel of the luggage compartment lid
(arrows) make it easier to pull the lid
down.
To avoid injuries, be sure that the
travel path of the luggage
compartment lid is clear when it is
closed, as with all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
completely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely
necessary to operate the vehicle with
the luggage compartment lid open:
>Close all windows. Shut the sliding/
tilt sunroof.
>Increase the airflow of the automatic
climate control to a high level. Refer
to page 84.<

Automatic climate controlTips for pleasant drivingUse the automatic system (switch on
AUTO Ð button 7).
>Select an interior temperature that is
comfortable for you, e. g. 72 7
(+22 6)
>Whenever 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 passengers
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
somewhat cooler promotes driving
without fatigue.
Detailed setting options are described
for you in the following sections.
Your vehicle is set in such a
manner that, when you unlock the
vehicle with your individualized remote
control, your own personalized setting
for the automatic climate control is initi-
ated.<
Automatic air distribution
The automatic program will take
over
>automatically distributing the air
supply to the vents, as well as
>automatically adjusting the amount of
incoming air.
It will adapt to the settings you have
made for the temperature desired in the
passenger compartment Ð taking
outside influences into account
(summer, winter) Ð and will provide you
with a comfortable climate in the
vehicle at any time of the year.
>Select an interior temperature that is
comfortable for you e. g. 72 7
(+22 6). The temperature selected
and AUTO for air supply will
appear in the display 10. Refer to the
overview on page 84
>Open up the vents for the upper body
>Switch on the air conditioner in warm
weather. The maximum cooling
capacity is achieved when you set
rotary dial 3 (refer to page 88) 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,
even if the air conditioner is on. 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 88) 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). The
air conditioner is at full cooling output
at 60 7 (+16 6).<

Automatic climate control Air supply (fan)
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 of 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 is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.
Defrosting the windshield and
removing condensation from the
windows
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 at outside temperatures
below approx. 41 7 (+5 6). This will
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, that then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
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 recircu-
lates the air already within the vehicle.
By repeatedly pressing the button, you
can select one of three different opera-
tion modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on Ð Auto-
matic mode: the system detects
pollutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates 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.

88n
Automatic climate control
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. Refer to
page 67.
Draft-free ventilation You can adjust the vents for the upper
body area to select the optimum airflow
rates and directions for your personal
requirements:
1 Rotary dials for opening and closing
the vents at any setting desired
2 Lever for changing the direction of
the airflow.
Set the vents so that the air flows
past you and is not directed straight
at you.
3 Using the rotary dial, you can mix
more or less cool air with the air
coming out of the vents aimed at the
upper body.
Microfilter/Activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center will replace the combined
filter as a standard part of your sched-
uled maintenance. A substantial reduc-
tion in airflow indicates that the filter
needs to be replaced early.
For additional details on changing the
filter, refer to page 152.

112n
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 116.
DOT Quality Grades Treadwear
Traction AA A B C
Temperature A B C
All passenger vehicle 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 (1 g) 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,
aquaplaning, or peak traction charac-
teristics.< TemperatureThe temperature grades are A (the
highest), B, and C, representing the
tireÕs 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 vehicle tires must meet
under the Federal Motor 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, 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, since
driving safety may be impaired by
their use. This is due to the possible
variations in casing structures and, in
some cases, to their extreme age,
factors that can lead to a decrease in
their durability.<
