Automatic transmission
If you have selected the AMG menu in the
control system and you are driving in the
manual program modeM, upshift
indicator2 in the multifunction display
advises you to upshift before the engine
reaches the overspeed range. Thus you
can drive at the maximum engine speed for
each gear without overrevving the engine.
1Gear indicator
2Upshift indicator
Shift to the next higher gear.
The fuel supply will otherwise be inter-
rupted to prevent the engine from over-
revving.Downshifting

Briefly press the gear selector lever to
the left in theD-direction.
or

Briefly pull left shift paddle1
(page 180).
The transmission shifts to the next
lower gear.Kickdown
Using the kickdown when driving in the
manual program modeM is not possible.
Deactivating manual shift program

Press the program mode selector
switch (
page 182) repeatedly
until
Cor
S appears in the multifunction
display.
or

Restart the engine.
The transmission will go to the
automatic program mode (C orS).
The manual program modeM is not
stored.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.i
When you brake or stop, the transmission
shifts down to a gear from which you can easily
accelerate or take off.

184 Controls in detailAutomatic transmissionEmergency operation (Limp-Home Mode)
If vehicle acceleration becomes less re-
sponsive or sluggish or the transmission
no longer shifts, the transmission is most
likely operating in limp-home (emergency
operation) mode. In this mode only second
gear and reverse gear can be selected.
Stop the vehicle in a safe location.

Move the gear selector lever to park
positionP.

Turn off the engine.

Wait at least 10 seconds before
restarting.

Restart the engine.

Move the gear selector lever to
positionD (for second gear) or
positionR.

Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.

194 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.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/C mode (
page 203) is
deactivated.
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, use the air distribu-
tion controls (
page 192) or (
page 193)
to direct the air to air vents in the vehicle in-
terior that are not in the immediate area of
unprotected skin.

i
When operating the climate control system
in automatic mode, you will only rarely need to
adjust the temperature, air volume and air distri-
bution.
In automatic mode, cooling with dehumidify is
switched on. This function can be switched off.Warning!
G
If you switch off the cooling function the
windows can fog up more quickly. Window
fogging may impair visibility and endanger
you and others.i
You can switch the automatic climate con-
trol system on and off for each side of the pas-
senger compartment as desired.

203 Controls in detail
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 192) or
(
page 193).
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 192) or
(
page 193) 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.
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.
!
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.

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 216).
The cruise control is canceled. The last
speed set is stored for later use.Setting a higher speed

Lift the cruise control lever in direction
of arrow1 (
page 216) and hold it
up until the desired speed is reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control lever in
direction of arrow2 (
page 216) and
hold it down until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.
i
The last stored speed is canceled when you
turn off the engine.

you move the gear selector lever to position
N while driving.
The segments in the multifunction display
(
page 141) 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 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.

A signal will sound. The
DISTRONIC Off
message appears in the multifunction
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 Off
.
The 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 approximately
20 mph (30 km/h) by operation of the
system. At that time the driver must apply
the brakes in order to reduce vehicle speed
further or bring it to a stop.
