Deadlocking
Deadlocking renders the interior door
controls inoperative.
It also deactivates the manual central
locking button.
Therefore, never leave anyone inside
the vehicle when it is deadlocked.
With the vehicle unlocked, press
this button.
Within five seconds, press this button again
to deadlock the vehicle.
Locating your vehicle
This function allows you to identify your vehicle
from a distance, particularly in poor light. Your
vehicle must be locked.
Press this button.
This will switch on the courtesy lamps and the
direction indicators will flash for about
10 seconds.
