KEYLESS-GO
General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a key
in the vehicle.
Locking and unlocking
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 KEY-
LESS-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
handle 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 vehi-
cle. This occurs, for example:
R
when starting the engine
R
whilst driving
R
when the external door handles are
touched
R
during convenience closing
