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.
KEYLESS-GO checks whether a valid key is in
the vehicle by periodically establishing a radio
connection between the vehicle and the key.
This happens:
R
when starting the engine
R
whilst driving
R
when the external door handles are touched
R
during convenience closing
