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.

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.
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 switched 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 regardless 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.
