200 Controls in detail4-zone automatic climate control
The climate control is a 4-zone intelligent
climate control system. Your vehicle interi-
or is divided into 4 zones.With the help of a sun sensor, the climate
control determines the relation of the sun
to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
You can set the temperature for each of
the 4 zones separately.
The climate control is operational whenev-
er the engine is running. It cools the vehi-
cle’s interior according to the angle and
intensity of the sun’s rays, the outside tem-
perature and the selected temperature.
You can operate the climate control sys-
tem in either the automatic or manual
mode.
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burn or frostbite to unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary change the air flow
using the air distribution controls
(page 199) to direct the air away from the
air vents.

4-zone automatic climate control
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 198) or
(
page 199).
The indicator lamp on the button goes
out. The cooling function switches off
after a short delay.
Activating
Moist air can fog up the windows. You can
dehumidify the air with the air condition-
ing.

Press button2 (
page 198) or
(
page 199) 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.
iCondensation may drip out from under-
neath 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.
!If the air conditioning cannot be turned
on again, this indicates that the air con-
ditioning is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.iIf you switch on the residual heat
function when temperatures are high,
only the ventilation will be switched on.

224 Controls in detailDriving systemsCanceling 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 223).

pedal.
In this case the segments in the
multifunction display (

you move the gear selector lever to
position N while driving.
The segments in the multifunction
display (
page 147) go out, and an
acoustic warning sounds.
!Moving the 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 skid-
ding (e.g. on icy roads).iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.

ometer segments from the selected speed
to the vehicle maximum speed are illumi-
nated.
iWhen you use the cruise control lever
to decelerate, the brake system will
automatically brake the vehicle if the
engine’s braking power does not brake
the vehicle 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.

Start the engine (
page 49).

Press the damping button1 until the
desired suspension style is set.Vehicle level control
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.
Select the raised level only when required
by current driving conditions. Otherwise


handling may be impaired


fuel consumption may increase
!If you have selected the Comfort sus-
pension tuning (
page 238), the vehi-
cle 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 lowering. Your ve-
hicle could otherwise be damaged.
iThe selected suspension style is stored
in memory, even after the SmartKey is
removed from the starter switch.
iThese height adjustments are so small
that you may not notice any change.Warning!
G
To help avoid personal injury, keep hands
and feet away from wheel housing area, and
stay away from under the vehicle when low-
ering the vehicle chassis.
