4-zone automatic climate control
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.Deactivating
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 224) or
(
page 225).
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 224) or
(
page 225) 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.
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.

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.Activating

!
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.

Regardless of the selected air volume, the
blower operates at low speed.

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 247).
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.

positionN while driving
The segments in the multifunction display
(

sounds.
!
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.

Distronic system:
Briefly tip the cruise control lever in di-
rection of arrow3 (
page 254).
or

Step on the brake pedal.
Distronic will be deactivated. The last
speed set will be stored into memory.Distronic deactivates automatically when

Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the vehi-
cle ahead. The set distance will be shown
in the multifunction display.
The thumbwheel for making the time set-
ting is located on the lower section of the
center console.
i
The following message will appear in the
multifunction display for approximately
5seconds:
DISTRONIC offThe last stored speed is deleted when you turn
off the engine.
Warning!
G
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.
Warning!
G
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving recom-
mendations for safe following distance.

Your vehicle automatically adjusts its ride
height to


increase vehicle safety


reduce fuel consumption
The following vehicle chassis ride heights
can be selected:


Normal


Raised
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


At a speed exceeding approximately
68 mph (110 km/h) with normal level
set or exceeding 75 mph (120 km/h)
with raised level set, the ride height is
reduced automatically. The table on
the next page provides an overview of
the vehicle levels.


With decreasing speed, the ride height
is again raised to the normal level.
!
If you have selected the Comfort suspen-
sion tuning, the vehicle lowers slightly when you
lock it within approximately 60 seconds after
switching off the engine. When parking, make
sure that your vehicle cannot come into contact
with other objects, such as a curb, while lower-
ing. Your vehicle could otherwise be damaged.

The selected suspension style is stored in
memory, even after the SmartKey is removed
from the starter switch.
