closed. The doors and the luggage  
compartment lid are unlocked or locked  
only. The anti-theft alarm system is not  
activated.  
Because passengers or animals  
remaining in the vehicle could lock  
the doors from the inside, you should  
always remove the key and take it with  
you to ensure that you remain able to  
unlock the vehicle from the outside at  
all times.<  
You can also have the key preset  
to engage the central locking  
system as soon as you start to drive.<
