If 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.460de011
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.<460de067
Do not drive with the luggage
compartment lid open, since
exhaust fumes could penetrate the inte-
rior of the vehicle. Should it be abso-
lutely necessary to operate the vehicle
with the luggage compartment lid open:
>Close all windows and the sliding/tilt
sunroof.
>Increase the air supply for the air
conditioner or the automatic climate
control to a high level. Refer to
page 92 or 98.<

Tips for pleasant drivingUse the automatic system (switch on
AUTO Ð 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 condi-
tioner (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 air 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 section.
Automatic air distribution
The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and in
addition 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 temperature selected and
AUTO for the air supply appear in
display (10), refer to the overview on
page 98. 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) to cold.
Refer to page 102.
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 tempera-
ture, regardless of the season.
Set rotary dial 3 (refer to "Draft-free
ventilation" on page 102) 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.
The full, uncontrolled heater
output is available at 90 7
(+32 6). At a setting of 60 7 (+16 6),
the full cooling output is available when
the air conditioner is activated.<

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 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 of the automatic
climate control.
To defrost the windshield and
side 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.
Switch off the air conditioner at outside
temperatures 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, which 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 air flow from
the outside. The system then recircu-
lates 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.<

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 71.
Draft-free ventilation Set the ventilation outlets for your upper
body area so that it is comfortable for
you:
Use rotary dials (1) to open and close
the air outlets through an infinitely-vari-
able range. You can adjust the direction
of the airflow with the levers (2).
Set the 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 your upper body
by warming or cooling the air as
desired.460de040
Microfilter/Activated-charcoal
filterThe microfilter traps incoming dust and
pollen. The activated-charcoal filter
helps clean the incoming outside air of
gaseous pollutants. Your BMW center
will replace this combinated filter during
the regularly scheduled maintenance. A
substantial reduction in air supply indi-
cates that the filter must be replaced
before normal maintenance.
For additional information on the filter
change, refer to page 171.

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, beginning on
page 130.

All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to these
grades. 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. 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 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, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. applicable on the tire sidewall between
tread shoulder and maximum section

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, factors that
can lead to a decrease in their dura-
bility.<
