Unlocking and locking
Central locking* and locking system Introduction
Central locking functions correctly when all the doors and the rear lid are
correctly shut. If the driver door is open, the vehicle cannot be locked with
the key.
The battery of a vehicle left unlocked during a long period (for instance, in a
private garage) may run down and fail to start the motor.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Vehicle key set ⇒ page 28
● Doors ⇒ page 38
● Rear lid ⇒ page 40
● Electric windows ⇒ page 43
● Emergency locking and unlocking ⇒ page 243
WARNING
The incorrect use of the central locking system may cause serious inju-
ries.
● The central locking system will lock all doors. A vehicle locked from
the inside can prevent any non-authorised individual from opening the
doors and accessing the vehicle. Nevertheless, in case of emergency or
accident, locked doors will complicate access to the passenger compart-
ment to help the passengers.
● Never leave children or disabled people alone in the vehicle. The cen-
tral locking button can be used to lock all the doors from within. There-
fore, passengers will be locked inside the vehicle. Individuals locked in
the vehicle can be exposed to very high or very low temperatures.
WARNING (Continued)
● Depending on the time of the year, temperatures inside a locked and
closed vehicle can be extremely high or extremely low resulting in seri-
ous injuries and illness or even death, particularly for young children.
● Never leave individuals locked in a closed and locked vehicle. In case
of emergency, they may not be able to exit the vehicle by themselves or
get help.

Description of the central locking system
The central locking system allows all doors and the rear lid to be locked and
unlocked centrally.
● From outside, using the vehicle key.
● From inside, by pushing the central locking button ⇒ page 36.
The central locking system can be activated or deactivated at a specialised
workshop.
In case of a vehicle key fault or central locking system fault, all doors can be
locked or unlocked manually.
Locking the vehicle after the airbags have been deployed
If the airbags are deployed due to an accident, the vehicle will be automati-
cally and completely unlocked. Depending on the amount of damage, the
vehicle can be locked following an accident in the following ways: 
