Central locking system
The concept
The central locking system functions when the
driver's door is closed.
The system simultaneously engages and
releases the locks on the following:
>Doors
> Trunk lid
> Fuel filler flap
> Convertible: glove compartment
Operating from outside
>Via the remote control
> Using the door lock
> In cars with Comfort Access, via the handles
on the driver's door and the front passenger
door
At the same time as locking and unlocking via
the remote control:
> Welcome lights, the inte rior light, and the
courtesy lighting are switched on and off.
> Alarm system, refer to page 37, is armed or
disarmed.
Operating from inside
By means of the button fo r central locking, refer
to page 35.
In the event of a sufficien tly severe accident, the
central locking system un locks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.

Automatic climate control
Comfortable interior climate
AUTO program7 offers the ideal air distribution
and air volume for almost all conditions, refer to
AUTO program below. All you need to do is
select an interior temperature which is comfort-
able for you.
The following sections inform you in detail
about how to adjust the settings.
Most settings are stored for the remote control
currently in use, refer also to Personal Profile
settings on page 31.
Adjusting air distribution manually
The air distribution can be
switched on and off manually. The
air is directed to the windshield, to
the upper body area and to the
footwell.
The automatic air distribution can be switched
back on by pressing the AUTO button. The
cooling function is swit ched on automatically
and the manual air distribution setting is
cleared.
Temperature
Turn to set the desired tempera-
ture.
The automatic climate control
achieves this temperature as
quickly as possible rega rdless of the season,
using maximum cooling or heating power if nec-
essary, and then maintains it.
Avoid rapid switching between different tem-
perature settings. The automatic climate con-
trol will not have sufficient time to adjust the set
temperature.
Maximum heating power can be obtained with
the highest setting, regardless of the outside
temperature.
The system cools steadily in the lowest setting,
regardless of the outside temperature.
Maximum cooling
Press the button.
The system is set to the lowest
temperature, maximum air volume
and recirculated air mode.
Air flows out of the vent outlets for the upper
body region. Open them for this purpose.
Air is cooled as quickly as possible:
> Above an outside temperature of approx.
327/06
> When the engine is running

ControlsClimate
AUTO program
Press the button.
Air volume, air distribution and
temperature are controlled auto-
matically.
Depending on the selected temperature, AUTO
intensity and outside influences, the air is
directed toward the wi ndshield, the side win-
dows, the upper body and the footwell.
Pressing the AUTO button automatically
switches on the cooling function.
At the same time, a condensation sensor con-
trols the program so as to prevent window con-
densation as much as possible.
The program is switched off when the air distri-
bution is set manually or the button is pressed
again.
Intensity of the AUTO program
With the AUTO progra m switched on, auto-
matic control of the air volume and air distribu-
tion can be adjusted:
Press the left side of the button to
reduce the intensity. Press the
right side of the button to
increase it.
The selected intensity is shown on the display
of the automatic climate control.
Convertible program
The Convertible program is active when the
hardtop is open and the AUTO program is
switched on. In the Convertible program, the
automatic climate control is optimized for driv-
ing with the hardtop open . In addition, the air
volume is increased as vehicle speed increases.
The effectiveness of the Convertible pro-
gram can be enhanced considerably by
installing the wind deflector. <
Adjusting air volume manually
To be able to manually adjust the air volume,
switch off the AUTO program first.
Press the left side of the button to
reduce the air volume. Press the
right side of the button to
increase it.
The air flow rate is lowered or switched off
entirely to reduce the drain on the battery. The
display remains the same.
Automatic recirculated air control
AUC/Recirculated air mode
You can respond to unpleasant odors or pollut-
ants in the immediate environment by tempo-
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press the button repeatedly to
select an operating mode:
> LED off: outside air fl ows in continuously.
> Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air and
controls the shut-off automatically.
> Right-hand LED on, recirculated air mode:
the supply of outside air is permanently
shut off. If the windows fog over, switch off
recirculated air mode and increase the air
volume, if necessary. Ma ke sure that air can
flow onto the windshield.
The recirculated air mode should not be
used over an extended period of time;
otherwise, the air quality inside the car will dete-
riorate continuously. <
Via the button on the steering wheel
You can switch quickly between the recircu-
lated air mode and the previous mode using a
button on the steering wheel, refer to page 11.

Alternative oil types
If approved oils are not available, you can add
quantities of up to 1 US quart/1 liter of another
oil with the following specifications:
Oil change
Oil changes should only be performed by a
BMW center.
Coolant
Coolant consists of half water and half additive.
Not all commercially availa
ble additives are suit-
able for your BMW. Ask your BMW center about
suitable additives.
Only use suitable a dditives; otherwise,
engine damage may result. Because
additives are harmful to your health, it is impor-
tant to follow the instructions on the contain-
ers. <
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives. <
Coolant temperature
If the coolant and therefore the engine over-
heats, a warning lamp lights up. A message
appears on the Control Display.
Checking coolant level
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. <
1. Do not open the engine hood before the
engine has cooled down.
2. Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, th en continue turning
to open.
3. The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss elimi-
nated as soon as possible.
