Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. Pre-requi-
site for this is that:
R
you do not depress the brake pedal (vehi-
cles with automatic transmission)
R
you do not depress the clutch pedal (vehi-
cles with manual transmission)
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately (vehicles with automatic transmission).
If you depress the clutch pedal and press the
Start/Stop button, the engine starts immedi-
ately (vehicles with manual transmission).
To start the vehicle without actively using the
key:
R
the Start/Stop button must be inserted in
the ignition lock

the key must be in the vehicle
R
the vehicle must not be locked with the key
or KEYLESS-GO (

Do not keep the KEYLESS-GO 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 functionality of KEYLESS-
GO.
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
If you lock the vehicle centrally using the but-
ton on the front door (

continue to start the engine with the Start/
Stop button.
The engine can be switched off while the vehi-
cle is in motion by pressing and holding the

tion.
