To closeThe handle recesses in the interior trim
panel of the luggage compartment lid –
see 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,
following the same precautions as with
all closing procedures.<
Operate the vehicle only when the
luggage compartment lid is
closed. Otherwise, exhaust fumes
could penetrate the interior of the vehi-
cle. <
Should it be absolutely necessary to
operate the vehicle with the luggage
compartment lid open, with closed con-
vertible top:
1. Close all windows
2. Greatly increase the quantity of air
coming from the air conditioning or
automatic climate control system,
see page 100 or 104.
Emergency releaseThis lever releases the luggage com-
partment lid from inside the luggage
compartment.

ComputerMode selectionWith the ignition key in position 1 or
higher, you can call up information from
the computer using the button in the
turn signal lever. The information is dis-
played in the instrument cluster. Each
time you press the button briefly toward
the steering column, a new function is
called up in the display.
The displays appear in the following
order:
Time of day, outside temperature, aver-
age fuel consumption, cruising range,
average vehicle speed.
When the ignition key is turned to posi-
tion 1 or higher, the last active setting is
displayed.
Outside temperatureYou can change the units of measure,
6/7, for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster while
the temperature display is active. The
units of measure, 6/7, in the temper-
ature display of the automatic climate
control change automatically, refer to
page 104.Ice warningIf the outside temperature drops to
about 37.57/+36, then the computer
will automatically switch to a display of
the outside temperature. In addition, a
signal sounds as a warning and the dis-
play flashes for a brief period.
After giving an ice warning, the
display returns to the previous
setting.<
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57/+36, on
bridges or shaded road surfaces, for
instance.<

Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 7. Select the desired
interior temperature.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air distri-
bution mode by selecting the AUTO
button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for reference
purposes. We recommend 727/
+226 as a comfortable setting, even if
the air conditioning is on. When you
start the vehicle, the system ensures
that the selected temperature is
achieved as quickly as possible. It then
maintains this temperature, regardless
of the season.
To select the units of measure 6/7 of
the display, refer to page 85.
Air supply/Blower
By pressing the left or right half
of the button, you can vary the
air supply. This deactivates the auto-
matic control of the air supply, AUTO
disappears from the display panel. Nev-
ertheless, the automatic air distribution
remains unchanged. You can reactivate
the automatic air distribution mode by
selecting the AUTO button.
When the lowest blower speed is set
and you press the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioning are
switched off. The outside air supply is
blocked. You can reactivate the system
by pressing any button for the auto-
matic climate control.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle. It is
thus not unusual for a small puddle to
form under the car while the system is
running.<

Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
>Indicator lamps off: outside airflow is
on
>Left indicator lamp on – automatic
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The sys-
tem then recirculates the air currently
within the vehicle. Depending on the
air quality, the automatic system then
switches back and forth between
outside air supply and recirculation of
the air within the vehicle
>Right indicator lamp on: the flow of
outside air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
this mode off and increase the air sup-
ply as required.<
Rear window defroster
With the convertible top closed
or with the hardtop* mounted,
press the button. The indicator lamp
comes on. The rear window defroster
switches off automatically.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vent out-
lets
2Levers for airflow direction
3Use the rotary dial to control the tem-
perature of the airflow:
>Rotate toward blue – colder
>Rotate toward red – warmer.

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 replaces this combined fil-
ter as a standard part of your scheduled
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced before scheduled mainte-
nance.Automatic climate control*

ter or professional tire center, or have
the vehicle towed in to have it, its
wheels or its tires inspected.
Tire damage up to and including sud-
den and complete air loss can endan-
ger the lives of both the vehicle occu-
pants and other road users.<
Tire replacementTo maintain good handling and vehicle
response, use only tires of a single

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
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 tem-
perature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
