mate control
The following contains instructions and rec-
ommendations to enable you to get the most
out of your 3-zone automatic climate control.
R Activate climate control using the 0058and
005A/0056 buttons. The indicator lamps
above the 0058and005A/0056 buttons
light up.
R In automatic mode, you can also use the
00F0 button to set a climate mode
(FOCUS/MEDIUM/DIFFUSE). The
MEDIUM level is recommended.
R Set the temperature to 72 ‡ (22 †).
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com- partment as well. The indicator lamp above
the 00D6 button goes out.
R Use the residual heat function if you want to
heat or ventilate the vehicle interior when
the ignition is switched off. The residual
heat function can only be activated or deac- tivated with the ignition switched off.
R Vehicles with COMAND: if you change the
settings of the climate control system, the
climate status display appears for approx-
imately three seconds at the bottom of the
screen in the COMAND display. See also
the separate COMAND operating instruc-
tions. You will see the current settings of
the various climate control functions. During automatic engine switch-off, the cli-
mate control system only operates at a
reduced capacity. If you require the full cli-
mate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Y page 173). Operating the climate control sys-
tems
Switching climate control on/off
General notes When the climate control is switched off, the
air supply and air circulation are also
switched off. The windows could fog up.
Therefore, switch off climate control only
briefly
i Switch on climate control primarily using
the 0058 button (Y page 156).
In the rear compartment, you can also switch
climate control on and off using the 0058and
0078 buttons.

WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position Dor R
(Y page 176).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
The electric parking brake (Y page 192) is
automatically released.

i It is only possible to shift the transmission
from position Pto the desired position if
you depress the brake pedal. Only then is
the parking lock released. If the brake
pedal is not depressed, the DIRECT SELECT
lever can still be moved but the parking lock remains engaged.
i The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down.
You can open the doors from the inside at
any time.
You can also deactivate the automatic lock-
ing feature (Y page 287).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly. 170

ECO start/stop display
If the 00A7 symbol is shown in green in the
multifunction display, the ECO start/stop
function switches the engine off automati-
cally if the vehicle stops moving.
Every time you switch on the engine using the
SmartKey or the Start/Stop button, the ECO
start/stop function is activated.
If the ECO start/stop function has been man- ually deactivated (Y page 173) or a malfunc-
tion has caused the system to be deactivated, the 00A7 symbol is not displayed.
AMG vehicles: the ECO start/stop function
is only available in drive program C.
For further information on automatic engine
switch-off (Y page 172) and automatic
engine start (Y page 172).
Automatic engine switch-off If the vehicle is braked to a standstill in
Dor N,
the ECO start/stop function switches off the engine automatically.
The ECO start/stop function is operational
and the 00A7symbol is displayed in green in

R the outside temperature is within the range
that is suitable for the system.
R the engine is at normal operating temper-
ature.
R the set temperature for the vehicle interior

R the battery is sufficiently charged. R
the system detects that the windshield is
not fogged up when the air-conditioning
system is switched on.
R the hood is closed.
R the driver's door is closed and the driver's
seat belt is fastened.
If conditions for automatic engine switch-off
have not been fulfilled, the 00A7symbol will
be shown in yellow.
i All of the vehicle's systems remain active
when the engine has been stopped auto-
matically.
i The HOLD function can be activated if the
engine has been switched off automati-
cally. It is then not necessary to continue
applying the brakes during the automatic
stop phase. When you depress the accel-
erator pedal, the engine starts automati-
cally and the braking effect of the HOLD
function is deactivated.
i All vehicles (apart from AMG vehicles):
automatic engine switch-off can take place a maximum of four times consecutively (ini-
tial stop then repeated three times). The
00A7 symbol is shown in yellow in the mul-
tifunction display after the engine has been started automatically for the fourth time.
When the 00A7symbol is shown in green in
