Luggage compartment lidTo closeThe handle recesses (arrows) in the
interior trim panel of the luggage
compartment lid 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.
Do not drive with the luggage compart-
ment lid open, since exhaust fumes
could penetrate the interior of the
vehicle. Nevertheless, should it be
absolutely necessary to operate the
vehicle with the luggage compartment
lid open (with closed convertible top):
>Close all windows
>Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
pages 89, 92.<
Emergency releaseThis lever releases the luggage
compartment lid from the luggage
compartment's interior.

Vehicle Memory, Key Memory How the system functionsYou have probably frequently wished
that you could configure individual
functions of your vehicles to reflect your
own personal requirements. In engi-
neering your vehicle, BMW has
included several user-defined func-
tions in the vehicle's design. Your BMW
center can make these settings for you
in accordance with your wishes.
There are settings related to the vehicle
("Vehicle Memory") and settings related
to individuals ("Key Memory"). You can
have up to four different basic settings
adjusted for four different persons. The
only requirement is that each person
uses his or her own remote control key.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes
adjustments accordingly.
In order for you to distinguish between
different keys, colored decals are
supplied together with the keys.What the system can doYour BMW center can provide you with
details on the possibilities that the
Vehicle and Key Memory systems offer.
Examples for Vehicle Memory:
>Various signals that can serve as
acknowledgment for locking and
unlocking the vehicle, refer to
pages 29, 30
>Activating/deactivating operation of
"Follow me home," refer to page 85.Examples for Key Memory:
>Locking the vehicle after driving off,
refer to page 33
>Automatically moving the seat and
outside mirror into position for that
particular person when unlocking the
vehicle, refer to page 49
>Calling up customized settings for the
automatic climate control when
unlocking using the remote control,
refer to page 92
>After the engine is started, calling up
of the last selected driving program
for each shifting mode, refer to
page 68.
You will see this symbol
throughout the Owner's Manual. It
is to remind you at appropriate places
of the settings that are available to
you.<

Tips for pleasant drivingUse the automatic system (switch on
AUTO button 7). Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
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. The AUTO program assumes
the adjustment of the air distri-
bution and the air supply for you and Ð
in addition to that Ð adapts the temper-
ature to external influences (summer,
winter) to meet preferences you can
specify.
Individual air distribution
You also have the option of indi-
vidually configuring the air
distribution pattern to suit your
own personal preferences.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. The system
directs air to the windows , the upper
body and into the footwells . You
can reactivate the automatic air supply
by pressing the AUTO button.
Temperature
The displayed temperatures are
reference values for the interior
temperature. We recommend 727
(+226) 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.
Air supply (blower)
By pressing the left or right side
of the button, you can vary the
air supply. This deactivates the auto-
matic air supply Ð the AUTO display
disappears from the panel. Neverthe-
less, the automatic air distribution
remains unchanged. You can reactivate
the automatic air supply by pressing the
AUTO button.
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.
To defrost windows and remove
condensation
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.
Window mist will be reduced by
switching on the air conditioner.
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 airflow from
the outside. The system then recircu-
lates the air currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different oper-
ating 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 currently 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 the
recirculated air off and increase the air
supply as required.<
Rear window defroster
With the convertible top closed
or with the hardtop
* mounted,
press the button. The indicator lamp
remains on. The rear window defroster
switches off automatically.
The rear window defroster auto-
matically assumes operation
within 5 minutes after the engine is
started at outside temperatures below
40 7 (4 6).<

Draft-free ventilation You can adjust the blower controls 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 Selector lever for airflow direction
3 With the rotary dial you can adjust the
temperature of the outgoing air.
>Turn toward blue Ð colder
>Turn toward red Ð 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 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.

DOT Quality GradesTreadwear
Traction AA A B C
Temperature A B C
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 (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,
hydroplaning, or peak traction charac-
teristics.< TemperatureThe temperature grades are A (the
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, 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:
