Important safety notes

WARNING
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:
R keep the air inlet between the windscreen
and the bonnet free of blockages, such as
ice, snow or leaves.
R never cover the vents or ventilation grilles
in the vehicle interior. 154

If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehi- cle. This occurs, for example, when starting
the engine.
To start the vehicle without actively using the
key:
R the Start/Stop button must be inserted in
the ignition lock
R the key must be in the vehicle
R the vehicle must not be locked with the key
or KEYLESS-GO (Y page 85)
Do not keep the key:
R with electronic devices, e.g. a mobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. a metal case
This can affect the key's functionality.
If you lock the vehicle with the key's remote
control or with KEYLESS-GO, after a short
time:
R you will not be able to switch on the ignition
with the Start/Stop button
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again

continue to start the engine with the Start/

cle is in motion by pressing and holding the
