( page 135).

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 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 you lock or unlock the
vehicle with KEYLESS-GO, the distance between
the key and the door handle must not be greater
than 1 m.
A check that periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in or in the
direct vicinity of the vehicle. This occurs, for
example:
during engine start
R
during driving
R
when the external door handles are touched
R
during convenience closing
R
To unlock the vehicle: touch the inner sur-
