2 remote control keys
In certain European markets, vehicles with alarm are equipped with 2 re-
mote control keys.
WARNING
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
● Wait for the vehicle to come to a standstill before removing the igni-
tion key from the lock! Otherwise, the steering lock could engage sud-
denly, causing an accident.

Activating the function
–Briefly press the knob ⇒ Fig. 86 to release it from its set posi-
tion.
– Turn the knob to position 1.

tion.

The coming home and leaving home functions are controlled by light sen-
sors in the interior mirror housing. The system will function when the follow-
ing requirements are met:
● The knob is set to position 1.
● The headlights and the ignition are switched off.
● Dark conditions; the sensors register little or no light.
Coming home
When the system is enabled and it is dark, the corresponding exterior lights
switch on as soon as the driver door is opened.
The exterior lights will stay on for up to a maximum of 2 minutes as long as
one of the doors or the rear lid is open.
The exterior lights stay on for about 30 seconds to light up the area around
the vehicle after all the doors and the rear lid have been closed. This time interval is factory-set, but you can have it changed by a special-
ised workshop to suit your own requirements (max. setting is 60 seconds).
Leaving home
The exterior lights are switched on when the vehicle is unlocked with the

button on the remote control key.
The exterior lights go out when the driver door is opened or after 60 sec-
onds when the vehicle locks itself again automatically
⇒ page 108.
WARNING
Before leaving the vehicle, remove the key from the ignition, as the lights
will not go out if the coming home function is activated. This will lead to
battery discharge and vehicle breakdown.
Note
● If you always wish to use the coming home and leaving home functions,
you can leave them permanently switched on. As the system is controlled
via a photosensor, it will only work in dark conditions.
● Permanent use of the coming home and leaving home functions, partic-
ularly on short journeys, will increase the load on the battery. To make sure
the battery is always sufficiently charged, occasionally drive longer distan-
ces.
● If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the ig-
nition.
● Observe all relevant legal requirements when using the signalling and
lighting systems described here. 
