Luggage compartment lidTo open 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 and the sliding/tilt
sunroof
>Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
pages 83, 86.<

Vehicle Memory, Key Memory How the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own indi-
vidual preferences. In engineering your
vehicle, BMW has incorporated a
number of options for personal adjust-
ment that can be programmed into your
vehicle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle
("Vehicle Memory") or the individual
("Key Memory"). Provided that each
person has a separate remote-control
key, you can have your BMW center
enter adjustment data for as many as
four different individuals into the
system.
The system then relies on a bilateral
data exchange to identify the individual
user and dial in the selected settings
whenever the remote control unit is
used to disengage the door locks.
Color-coded decals have been
provided to help you distinguish indi-
vidual keys with different settings.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 as acknowledgment
when locking or unlocking your
vehicle, refer to pages 29, 30
>Activate/deactivate the "Follow me
home" lamps function, refer to
page 80.Examples for Key Memory:
>Locks the vehicle after driving off,
refer to page 33
>Automatically adjusts the seat and
exterior mirrors to your personal
programmed settings, refer to
page 46
>Calls up customized settings for the
automatic climate control when
unlocking using the remote control,
refer to page 87
>After the engine is started, calling up
of the last selected driving program
for each shifting mode, refer to
page 63.
You will see this symbol through-
out 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 vehicle is set 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 can cancel the AUTO
program by selecting specific
distribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic air supply 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
windshield 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
conditioning 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 supply 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
air supply 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 air
supply 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 mode off and increase
the air supply as required. When the rear window defroster
is activated, the indicator lamp
comes 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 infinitely-variable
opening and closing of the vents
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 air supply indicates that the filter
needs to be replaced early.
To actuate, press the button briefly with
ignition key in position 1 or higher.

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,
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, underinflation, 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:
