2019 MERCEDES-BENZ METRIS air condition

Regulating climate control automati-
cally
General notes
When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification function
is also activated. If desired, the cooling with air
dehumidification function can be deactivated
(
Ypage 114).
Dual-zone automatic climate control
Automatic mode for automatic climate control
settings can only be activated or deactivated on
the first menu level. If you do not set a new value
for the rear-compartment climate control in the second menu level within approx. ten seconds,
the control panel display goes back to the first
menu level.
XSwitch on climate control (Ypage 113).
XSet temperature for the driver's and front-
passenger side and, for vehicles with rear-
compartment air conditioning, for the rear
compartment, too (
Ypage 115).
XTo switch automatic mode on or off: press
the à button.
If the indicator lamp in the Ãbutton lights
up, automatic mode is activated. The airflow
and air distribution are controlled automati-
cally and the windshield defrosting function is
deactivated.
If you deactivate automatic mode, the auto-
matic climate control system saves the current
settings.
In automatic mode, if you adjust the airflow or
air distribution manually, the indicator lamp
above the Ãbutton goes out. The function
which has not been changed manually, however,
continues to be controlled automatically.
Setting the temperature

When doing so, only change the temperature
in small increments, and start in the center
position or at 72 ‡ (22 †) (
Ypage 111).
Dual-zone automatic climate control
You can set the temperature separately for the
driver's and front-passenger side. In vehicles
with rear-compartment air conditioning, the
temperature for the rear can be set additionally.
Each set temperature is automatically main-
tained at a constant level.

The rear window defroster has switched off pre-
maturely or cannot be activated.
The vehicle starter battery is not sufficiently
charged.
XSwitch off any consumers that are not
required, e.g. reading lamps, interior lighting
or seat heating.
When the battery is sufficiently charged, the
rear window defroster can be activated again.

Convenience opening/pre-entry cli-
mate control
GWARNING
During convenience opening, body parts
could be drawn in or become trapped
between the side window and the door frame.
There is a risk of injury.
Monitor the entire opening procedure when
using convenience opening. When opening,
make sure that nobody touches the side win- dow. Release the %switch immediately if
somebody becomes trapped, to interrupt the
opening procedure.
XPre-entry climate control and conveni-
ence opening with the key: press and hold
the % button on the key.
The side windows open automatically and the
blower of the climate control system is acti-
vated.
XRelease the %button.
iAt high interior temperatures, the blower is
also switched on when a door is opened. This
means that slightly cooled air enters the vehi-
cle interior after the engine is started, to cool
the vehicle more rapidly.
Switching the residual heat function
on/off
General notes
Only vehicles with dual-zone automatic climate
control have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.
Switching the function on/off
XTurn the key to position 0in the ignition lock
or remove it.
XPress the Ìbutton.
If the residual heat function is activated, the
indicator lamp in the Ìbutton comes on.
The blower will run at a low speed regardless
of the airflow setting.
If you activate the residual heat function at
high temperatures, only the auxiliary ventila-
tion will be activated. The blower then runs at
medium speed.

matically

Rthe hood is closed.
Rthe driver's seat belt is fastened.
Rthe driver's door is closed.
Rthere is no danger of immediately rolling
backwards, e.g. when stopped on a steep gra-dient.
If a trailer is attached and/or a rear carrier
system is installed and connected electri-
cally, this danger is detected on less steep
gradients.
Only if all the conditions for automatic engine
switch-off are fulfilled, does the display show
the è ECO symbol.
All of the vehicle's systems remain active when
the engine is switched off automatically.
The engine can be switched off automatically a
maximum of four times (initial stop, then three subsequent stops) in succession. After that, the
display hides the èECO symbol. Automatic
engine switch-off is not possible again until the
è ECO symbol is shown again.
If you open the hood after an a

vated. Once the hood is closed, you have to start
the engine manually.
If the vehicle is stopped in transmission position
h ori, the ECO start/stop function switches
off the engine automatically once the vehicle is
stationary.
