Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air-dehumidification" func-
tion is operational when the vehicle is ready
to drive. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion.

General notes
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-

The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-

General notes
You can deactivate the flow of fresh air if

Pre-entry climate control via Smart-
Key
Before getting in, the vehicle interior can be
briefly warmed or ventilated in advance. In
addition, the air from the air vent can be pre-
cooled. The high-voltage battery must be sufficiently
charged before the "Pre-entry climate control
via key" function can be activated.
Activating/deactivating the pre-entry cli-
mate control (via key)
When the vehicle is unlocked using the Smart-
Key or KEYLESS-GO, the climate control func-
tions are activated.
The pre-cooling and pre-heating climate con-
trol functions last 5 minutes.
When the vehicle is pre-cooled, the following functions are activated as necessary:
RClimate control system
RCooling with air dehumidification
RBlower
When the vehicle is pre-heated, the following
functions are activated as necessary:
RClimate control system

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:
Rkeep the air inlet between the windshield
and the hood free of blockages, such as ice, snow or leaves.
Rnever cover the air vents or air intake grillesin the vehicle interior.
iFor optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position.
Setting the center air vents
XTo open the center air vents: turn the
adjuster in one of center air vents :coun-

iThe SmartKey can be turned in the igni-

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-GO function and a detachable Start/Stop but-
ton. A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example,
when starting the drive system.
When you insert the Start/Stop button into
the ignition lock, the system needs approx-
imately two seconds recognition time. You
can then use the Start/Stop button.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the drive system starts
immediately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in
the ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (
Ypage 73).
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. a mobile
phone or another SmartKey.
Rwith metallic objects, e.g. coins or metal
foil.
Rinside metallic objects, e.g. a metal case.
This can affect the functionality of KEYLESS-
GO.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will not be able to start the drive system
with the Start/Stop button until the vehicle is unlocked again.
If you lock the vehicle centrally using the but-
ton on the front door (
Ypage 80), you can
continue to start the drive system with the
Start/Stop button.
