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/tailgate
>Fuel filler flap
Operating from outside
>Via the remote control
>Via the door lock
*
>In cars with Comfort Access*, via the han-
dles on the driver's and front passenger
doors
In addition, if the remote control is used, the
interior lamps and the door's courtesy lamps
*
are also switched on or off. The alarm system*
is also armed or disarmed.
For further details of the alarm system,
refer to
page25.
Operating from inside
By means of the button for central locking, refer
to page22.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle
could lock the doors from the inside. You
should therefore take the remote control with
you when you leave the vehicle so that the latter
can be opened from outside.<
Unlocking
Press the button.
The interior lamps, the courtesy lamps
* and the
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or
the entire vehicle is to be unlocked when the
button is pressed for the first time.
For operating principle, refer to page64.
1.Switch on the ignition, refer to page46.
2.Lightly push button1 in the turn indicator
lever up or down repeatedly until the sym-
bol appears in the display accompanied by
the word "SET".
3.Press button 2.

Air distribution
Direct the flow of air to the win-
dows , to the upper body area
or to the footwell . Intermedi-
ate settings are possible.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the
interior of the car temporarily. The
system then recirculates the air currently within
the vehicle.
You can also activate/deactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page11.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
continuously for lengthy periods; otherwise, the
quality of the air inside the car will gradually
deteriorate.<
Air volume
Turn to adjust the air volume. The
higher the volume, the more effec-
tive the heating or cooling will be.The air volume may be reduced or the blower
may be switched off entirely to save on battery
power.
Switching the system on/off
Set any desired air volume to switch on the air
conditioner.
Turn the air volume rotary switch to 0. The
blower and air conditioner are completely
switched off and the air supply is cut off.
The outside air supply is blocked when
the air conditioner is switched off. If the air
quality deteriorates or the window fogs over,
switch the system back on and increase the air
volume.<
Switching cooling function on/off
The cooling function cools and
dehumidifies the incoming air
before reheating it according to the
temperature setting. This function
is only available while the engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes it quickly.
Depending on the weather, the windshield may
fog over briefly when the engine is started.

Comfortable interior climate
AUTO program5 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 page18.

Adding engine oil
Add a maximum of 1 US quart/1 liter of engine
oil no earlier than when the following warning
lamp lights up in the instrument cluster, or, if the
car has a gasoline engine, when the oil level
monitor shows "+1qt" or "+1l", or, if the car has
a diesel engine, when the oil level has dropped
to just above the lower marking on the dipstick,
refer to page137.
Add oil within the next 125 miles/200 km;
otherwise, the engine could be dam-
aged.<
Keep oils, greases, etc. out of the reach of
children and comply with the relevant
warnings on the containers. Otherwise, health
hazards may result.<
Oil change
Have oil changed only at your BMW center or at
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Oil types
Do not use oil additives as this could
result in engine damage.<
Specified engine oils
Your service center can advise you on which
engine oils have been approved by the manu-
facturer of your vehicle.
The engine oil quality is critical for the life of the
engine.
Approved oils can be identified by the following
specification:
Approved oils belong to the following viscosity
classes: SAE 0W-40, SAE 0W-30, SAE 5W-40
and SAE 5W-30.
Alternative oil types
If the approved engine oils are not available, up
to 1 US quart/1 liter of another oil with the fol-
lowing specification may be used:
API SM or higher
