LESS-GO key in the vehicle (
Locking and unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you need to carry the
key with you. You can combine the KEYLESS-GO
functions with the functions of a conventional
key. Unlock the vehicle by using KEYLESS-GO,
for instance, and lock it using the & button
on the key.
The driver's door and the door at which the han-
dle is used must both be closed. The key must be
outside the vehicle. When locking or unlocking
with KEYLESS-GO, the distance between the key
and the corresponding door handle must not be
greater than 1 m.
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
R
whilst driving
R
when using HANDS-FREE ACCESS
