Automatic climate control
Deactivating
Press buttone (
page 194).
The indicator lamp on the button goes
out.The system automatically switches to the
air recirculation mode if the carbon
monoxide (CO) or nitrogen oxide (NO
X)
concentration of the outside air increases
beyond a predetermined level, for example
in a tunnel.
The automatic air recirculation mode does
not function if ± is selected or if the
outside temperature has fallen below
41°F (5°C).
The activated charcoal filter should be
switched off when windows fog up on the
inside, or if the passenger compartment
needs to be quickly heated or cooled
down.
Rear window defroster
The rear window defroster uses a large
amount of power. To keep battery drain to
a minimum, switch off the defroster as
soon as the rear window is clear. The de-
froster is automatically deactivated after
approximately 6 to 17 minutes of opera-
tion depending on the outside tempera-
ture.
Activating
Press buttonF (
page 194).
The indicator lamp on the button
comes on.
Deactivating
Press buttonF (
page 194) again.
The indicator lamp on the button goes
out.
Warning!
G
Never operate the side windows and the
tilt/sliding sunroof if there is the possibility
of anyone being harmed by the closing pro-
cedure.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by pressing
the respective window switch. The closing of
the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
direction.
The closing of the side windows and
tilt/sliding sunroof can be reversed by again
pressing and holding thee button.
iIf you keep buttone pressed, the
side windows and the tilt/sliding sun-
roof will return to their previous posi-
tion.

Deactivating
It is possible to completely deactivate the
automatic climate control system.
Press button M (
page 194).
The display shows “0”.
Reactivating
There are several ways to reactivate the
automatic climate control system:
Press one of the following buttons,
M, P, U, a temperature con-
trol switch (
page 194) or air volume
switch 9 on the automatic climate
control panel.
Air conditioning
The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.
Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-
cle will then no longer be cooled or dehu-
midified.
Press button± (
page 194).
The indicator lamp on the button±
comes on.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

Warning!
G
When closing the windows, make sure that
there is no danger of anyone being harmed
by the closing procedure.
The closing of the door windows can be im-
mediately halted by releasing the switch or,
if the switch was pressed past the resis-
tance point and released, by pressing the re-
spective switch.
The door windows are equipped with the ex-
press-close and automatic reversal func-
tion. If the window encounters an
obstruction that blocks its path in a circum-
stance where you pressed the switch past
the resistance point and released it to close
the window, the automatic reversal function
will stop the window and open it slightly.
If the window encounters an obstruction
that blocks its path in a circumstance where
you are closing the window by pressing and
holding the switch, by pressing and holding
button ‹ on the SmartKey, or by press-
ing and holding the lock button (vehicles
with KEYLESS-GO*) on the door handle, the
automatic reversal function will not operate.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.iYou can also open or close the win-
dows using the SmartKey, see “Sum-
mer opening feature” (
page 209) and
“Convenience closing feature”
(
page 210).
You can close and reopen the windows
using the air recirculation button,
or the charcoal filter buttone in the
climate control panel (
page 194).

214 Controls in detailDriving systemsThe driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed.
Airmatic adjusts the vehicle suspen-
sion characteristics automatically and
controls the vehicle level.
ABC* with vehicle level control system,
with which you can change vehicle sus-
pension characteristics.
Parktronic*, which serves as a parking
assistant.
For information on the BAS, ABS, and ESP
driving systems, see “Driving safety sys-
tems” (
page 80).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 22).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

!Moving the gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to

not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.
