Luggage compartment lidOpening 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 sta-
tionary.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 com-
partment lid is clear when it is closed,
as with all closing procedures.<460de067
Operate the vehicle only when the
luggage compartment lid is com-
pletely closed. Otherwise, exhaust
fumes could penetrate the interior of
the vehicle. Should it be absolutely nec-
essary 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 86.<

Automatic climate controlTips for pleasant drivingUse the automatic system (switch on
AUTO Ð button 7). Select an interior
temperature that is comfortable for you
Ð we recommend 70 7 (22 6). When
the outside temperature is above 42 7
(5 6), you can also use the air condi-
tioner (12). This will dry the air as well
as preventing condensation on the win-
dow surfaces Ð if there are passengers
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 me-
dium position, since air that is some-
what cooler promotes driving without
fatigue.
Detailed setting options are described
for you in the following section.
Your vehicle is set in such a man-
ner that, when you unlock the car
with your personalized remote control,
your own personalized setting of the
automatic climate control is initiated.<
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 ex-
ternal 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 70 7
(22 6). The temperature selected and
AUTO for the air supply appear in
display (10), refer to the overview on
page 86. Open the air outlets for the
upper body area. Switch on the air con-
ditioner in warm weather. The maxi-
mum cooling capacity is achieved when
you set rotary dial (3) to cold. Refer to
page 90.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
You can direct air to flow onto the win-
dows , toward the upper body ,
and into the footwell .
Temperature
The figures in the display pro-
vide a general indication of inte-
rior temperature. We recommend 70 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 tem-
perature is reached as quickly as possi-
ble. It then maintains this temperature,
regardless of the season.
Set rotary dial (3; refer to "Draft-free
ventilation" on page 90) 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 out-
put is available starting at an inte-
rior temperature setting of 90 7
(32 6). At a setting of 60 7 (16 6),
the full cooling output is available when
the air conditioner is activated.<

Automatic climate control 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. 42 7
(5 6). This will help to prevent the win-
dows 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)
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.<

Automatic climate controlRear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically. Refer to
page 70.
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 de-
sired.460de040
Microfilter, activated-charcoal
filterA microfilter removes dust and pollen
from the incoming outside air. The acti-
vated-charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces the combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air
supply indicates that the filter must be
replaced before normal maintenance.
For additional details on the filter
change, refer to page 155.

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 118.
DOT Quality GradesTreadwear

Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments 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 (1 1/2) 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 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. 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 correspods to a level of
performance which all passenger car
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 ex-
cessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure. plicable on the tire sidewall between
