Vehicles with panorama roof*
Convenience closing:
Press and hold button,
(page 222) or (
page 223) until the
windows and the tilt/sliding panel are
closed or have reached the desired po-
sition. The indicator lamp on the button
comes on. The air recirculation mode is
activated.
Convenience opening:
Press and hold button, until the
windows and the tilt/sliding panel are
opened or have reached the desired
position. The indicator lamp on the but-
ton goes out. The air recirculation
mode is deactivated.Combination filter with pollutant-sensi-
tive air-recirculation mode
The combination filter reduces pollutants
and unpleasant odors in the outside air.
The pollutant-sensitive air-recirculation
mode automatically switches off the sup-
ply of outside air when pollutants are de-
tected in the air.
Air conditioning
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.
i
The pollutant-sensitive air-recirculation
mode is not possible if you have switched off the
air conditioning or if the temperature falls below
41°F (5°C).
i
Condensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.Warning!
G
If you turn off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog
up more quickly. Window fogging may
impair visibility and endanger you and
others.

It is possible to deactivate the air condi-
tioning (cooling) function of the climate
control system. The air in the vehicle will
then no longer be cooled or dehumidified.
Press button2 (
page 222) or
(
page 223).
The indicator lamp on the button goes
out.
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.
Press button2 (
page 222) or
(
page 223) again.
The indicator lamp on the button
comes on.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Residual heat and ventilation
(Canada only)
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.
!
If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned it-
self off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.
i
If you switch on the residual heat function
when temperatures are high, only the ventilation
will be switched on.
i
Regardless of the selected air volume, the
blower operates at low speed.

pedal.
Cruise control is activated.
The selected speed appears in the multi-
function display for approximately
5 seconds, and the corresponding speed-
ometer segments from the selected speed
to the vehicle maximum speed are illumi-
nated.Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever in
direction of arrow3 (
page 250).
The cruise control is canceled. The last
speed set is stored for later use.
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded.
Keep in mind that the cruise control is a
convenience system designed to assist the
driver during vehicle operation. The driver is
and must always remain responsible for the
vehicle’s speed and for safe brake
operation.
i
On uphill or downhill grades, the cruise con-
trol may not be able to maintain the set speed.
Once the grade eases, the set speed will be re-
sumed.
On downhill grades, the cruise control maintains
the set speed with active braking action.
In addition, on longer downhill grades the auto-
matic transmission will automatically downshift.
i
The last stored speed is canceled when you
turn off the engine.

until the desired speed is reached.
Release the cruise control lever.
The new speed is set.

!
Moving gear selector lever to positionN
while driving also cancels the cruise control.
However, the gear selector lever should not be
moved to positionN while driving except to
coast when the vehicle is in danger of skidding
(e.g. on icy roads).
i
Depressing the accelerator pedal does not
deactivate the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
i
When you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.

display for approximately 5 seconds.
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.
i
The following message will appear in the
multifunction display for approximately
5seconds:

Distronic switches off and releases the
brakes when the vehicle decelerates below
the minimum speed of 20 mph (30 km/h)
by operation of the system. At that time the
driver must apply the brakes in order to re-
duce vehicle speed further or bring it to a
stop.
