Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the SmartKey with you. You can combine the
functions of KEYLESS-GO with those of a
conventional SmartKey. Unlock the vehicle

it using the
&button on the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the SmartKey and the corresponding door handle must not be
greater than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid
SmartKey is in the vehicle. This occurs, for
example:
R
when the external door handles are
touched
R when starting the engine
R while the vehicle is in motion X
To unlock the vehicle: touch the inner
surface of the door handle.
