Important safety notes
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
General notes
The "Pre-entry climate control at departure
time" function is only available in PLUG-IN
HYBRID vehicles.
You can use the "Pre-entry climate control at
departure time" function to cool or heat the
vehicle interior if the engine is not running.
The "Pre-entry climate control at departure
time" function can be activated regardless of
whether or not the vehicle is connected to an
electric power supply. The condition of charge of
the high-voltage battery must be higher than the
specified minimum condition of charge, how-
ever.
When the vehicle is connected to an electric
power supply, priority is given to charging the
high-voltage battery to the specified minimum charge. "Pre-entry climate control at departure
time" is only activated subsequently.
The running time of the "Pre-entry climate con-
trol at departure time" function may be reduced
if:
Rthe vehicle is not connected to an electric
power supply and
Rthe high-voltage battery is not fully charged
With active "Pre-entry climate control at depar-
ture time" the condition of charge of the high-
voltage battery can be reduced, even if the
charge cable connector is connected.
When the vehicle is cooled, the following func-
tions are activated if required:
RClimate control system
RBlower
RSeat ventilation
When the vehicle is heated, the following func-
tions are activated if required:
RClimate control system
RBlower
RSeat heating
RSteering wheel heating
RExterior mirror heating
RRear window defroster

Setting the departure time
You can set the departure time using the on-
board computer or via the online access to the
vehicle. The activation of the "Pre-entry climate
control at departure time" function can be linked
to this departure time. Your vehicle will then be
cooled or heated until the desired temperature
is reached in time for the set departure time.
"Pre-entry climate control at departure time" will
be activated a maximum of 55 minutes before
departure. If the departure is delayed, the vehi-
cle will be heated or cooled for another five
minutes.
XTo set the departure time: set the departure
time using the on-board computer
(
Ypage 249). Set the departure time via the
online access to the vehicle (Ypage 176).
XTo activate or deactivate "Pre-entry cli-
mate control at departure time": activate
or deactivate "Pre-entry climate control at
departure time" via the multimedia system
(
Ypage 303). Set the "Pre-entry climate con-
trol at departure time" via the online access to
the vehicle (
Ypage 176).
When activating the "Pre-entry climate control
at departure time" function: you can select
whether only the driver's area or also the front-
passenger area should be heated or cooled.
The "Pre-entry climate control at departure
time" function sw
itches off automatically when
the vehicle is started. The following functions
remain active:
RSeat heating

Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:

GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.
