wheels when pulling away on slippery roads.
You could otherwise damage the drive train.

KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with
keys featuring an integrated KEYLESS-GO func-
tion and a detachable Start/Stop button.
The Start/Stop button must be inserted in the
ignition lock and the key must be in the vehicle.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
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 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 vehicle.
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 75)
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 button
on the front door (
Y
page 81), you can continue
to start the engine with the Start/Stop button.
The engine can be switched off while the vehicle
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 function.
