KEYLESS-GO

General notes
Vehicles with KEYLESS-GO are equipped with

SmartKeys featuring the integrated KEYLESS-

GO function and a detachable Start/Stop but-

ton.
The Start/Stop button must be inserted in the

ignition lock and the SmartKey must be in the

vehicle.
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 starts immedi-

ately.
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 engine.
To start the vehicle without actively using the

SmartKey:

the Start/Stop button must be inserted in

the ignition lock.

the SmartKey must be in the vehicle.

the vehicle must not be locked with the

SmartKey or KEYLESS-GO (

page 85).

Do not keep the KEYLESS-GO key:

with electronic devices, e.g. a mobile

phone or another SmartKey.

with metallic objects, e.g. coins or metal

foil.

inside 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:

you will not be able to switch on the ignition

with the Start/Stop button.

you will not be able to start the engine with

the Start/Stop button until the vehicle is

unlocked again.

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.

As soon as the ignition is switched on, all the

indicator lamps in the instrument cluster light

an indicator lamp either fails to go out after

starting the engine or lights up while driving

If Start/Stop button : has not yet been

pressed, this corresponds to the key being

removed from the ignition.
