To unlock and open
>Either unlock the doors together with
the button for the central locking sys-
tem and then pull each of the release
handles above the armrests
or
>pull the release handle for each door
twice: the initial pull unlocks the door,
and the second one opens it.
To lock
>Either use the central locking button to
lock all doors at once
or
>press the individual door lock buttons
down.
To prevent the driver from being
inadvertently locked out of the
vehicle, the driver's door lock button
will not engage as long as the door is
open.<
Since persons or animals in the vehi-
cle could lock the doors from the
inside, always take the vehicle keys with
you so that the vehicle can be opened
again from the outside at any time.<
Luggage compartment lid
To open from the outside
Turn the master key to the left as far as it
will go. The luggage compartment lid will
open slightly.
If the alarm system is armed, opening the
luggage compartment with the key will trig-
ger an alarm; refer also to page 27.
To open from the inside
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.
To close
The handle recess in the interior trim panel
of the luggage compartment lid makes it
easier to pull the lid down.
To avoid injuries, be sure that the
travel path of the luggage compart-
ment 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,
since exhaust fumes could penetrate into
the interior of the vehicle. Should it be
absolutely necessary to operate the vehicle
with the luggage compartment lid open and
with the convertible top closed:
>Close all windows
>Increase the air supply from the air con-
ditioner or automatic climate control to
a high level. Refer to page 55 or 57.<

All intermediate settings are pos-
sible.
Air supply/blower
You can set the blower to 8 differ-
ent levels. Both heating and ven-
tilation become more effective as
the air supply rate is increased.
Temperature
In order to increase the tempera-
ture of the passenger compart-
ment, turn to the right – red zone.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the tem-
perature setting – rewarmed.
Depending on the weather, the
windshield may fog over briefly when the
engine is started.
Condensation forms during operation
of the air conditioning system, which
then exits under the vehicle. Traces of con-
densed water on the ground underneath
the vehicle are thus normal.<
Outside-air/recirculated-air mode
If there are unpleasant odors in
the outside air, you can tempo-
rarily block the supply of incom-
ing air. The system then recircu-
lates the air currently within the vehicle.
If the windows fog over in the recircu-
lated air mode, switch this mode off
and increase the air supply as required.<
Rear window defroster
The indicator lamp lights up when
the rear window defroster is
active. The rear window defroster
switches off automatically.
Ventilation
You can adjust the blower controls for the
upper body area to obtain the optimum air-
flow rates and directions for your personal
requirements:
1Rotary dials for opening and closing the
vents at any setting desired
2Lever for adjusting airflow direction
Particle filter
The built-in particle filter removes dust and
pollen from the incoming air and in the
recirculated air mode. Your BMW center
will replace this filter during the regularly
scheduled maintenance. A substantial
reduction in airflow indicates that the filter
needs to be replaced earlier.

Controlling the climate for pleasant driving

Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior
temperature.
Detailed setting options are described for
you below.
Automatic air distribution and
supply
The AUTO program assumes the
adjustment of the air distribution
and air supply for you and in addi-
tion adapts the temperature to
external influences – summer, winter – to
meet preferences you can specify.
Individual air distribution
You can also direct air flow onto
the windows , toward the
upper body and into the foot-
well as you require. The arrow
lights up. The automatic air supply remains
unchanged. All intermediate settings are
possible. By pressing the AUTO button,
you can reactivate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a
general figure intended for refer-
ence purposes. 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.
Air supply/blower
You can set the blower through
an infinitely variable range of
speeds. This shuts off the auto-
matic air supply. The arrow lights
up. The automatic air distribution remains
unchanged. You can reactivate the auto-
matic air supply by pressing the AUTO but-
ton.
When you turn the rotary control toward
zero: the blower, heating and air condi-
tioner are switched off, and the air supply is stopped. You can reactivate the system by
turning the control toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
This program gives you maximum
cooling within a short period of
time.
The temperature is set to the lowest possi-
ble value. The system switches into the
recirculated air mode and air flows at max-
imum blower speed from the air outlets
only. Therefore, the air outlets must always
be open when you select this program.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the tem-
perature setting – rewarmed.
Depending on the weather, the
windshield may fog over briefly when the
engine is started.
The air conditioning system is automati-
cally switched on when you use the AUTO
program.
Condensation forms during operation
of the air conditioning system, which
then exits under the vehicle. Traces of con-
densed water on the ground underneath
the vehicle are thus normal.<
Outside air/Automatic recirculated
air control AUC/recirculated air
mode
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.
By repeatedly pressing the button, you can
select one of three different operating
modes.

Wheels and tires
74 one and one-half (1 γ) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction
The 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 specified govern-
ment 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 brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics.<
Temperature
The 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 conditions 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 car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre-
sent 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 load-
ing, either separately or in combination,
can cause heat buildup and possible tire
failure.<
Uniform Tire Quality Grading
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Tread wear 200 Traction AA
Temperature A
Wheel and tire combina-
tions
The right choice
Use wheels and tires approved by
BMW for your particular vehicle. Vari-
ations in factors such as manufacturing tol-
erances mean that even wheels and tires
with identical official size ratings could
actually have dimensions different from the
approved units. These differences could
lead to body contact, and with it the risk of
severe accidents. If non-approved wheels
and tires are used, BMW cannot evaluate
their suitability, and therefore cannot be
held liable for driving safety.<
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. Consult your BMW center
for more information. Observe any country-
specific regulations, e.g. on making a cor-
responding entry in the vehicle documents.
The correct wheel and tire combina-
tion affects different systems such as
ABS, DSC, DTC and DBC. The function of
these systems is impaired if improper
wheel and tire combinations are used.
For this reason, use tires of the same brand
and tread configuration. In the event of a
flat tire, for example, remount the approved
wheel and tire combination as soon as pos-
sible.<
