KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO
function and adetachable Start/Stop button. Driving
179Driving and parking Z

The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehi-
cle.
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 engine start simmedi-
ately.
Ac heck which periodically establishes aradio
connection between the vehicle and the key
determines whether avalid 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 95)
Do not keep the KEYLESS-GO key:
R with electronic devices, e.g. amobile
phone or another key
R with metallic objects, e.g. coins or metal
film
R inside metallic objects, e.g. ametal 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 ashort
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 frontd oor (Ypage 101), you can
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
Start/Stop button for three seconds. This
function operates independently of the ECO
start/stop automatic engine switch-off func-
tion.

When you switch on the ignition ,all of the
indicator lamps in the instrument cluster light up. Further information on situations where
an indicator lamp either fails to go out after
