3. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
Procedure for disconnecting the battery:
– switch off the ignition,
– switch off all electrical consumers,
– Wait at least 1 minute for the electronic systems to switch off,
– disconnect the battery, starting with the negative terminal.

Electric central door locking:
Central locking and unlocking of the side door is dependent on the presence of the fuel tank cap sensor.
The doors can be centrally locked and unlocked using the CPE* button.
Luggage compartment lock:
The luggage compartment locking and unlocking command is provided by the UCH.
Front driver and passenger locks:
The front driver and passenger door locking and unlocking command is provided by the UCH.
Side door lock:
Central locking and unlocking of the side door is carried out by the UCH.
Transponder and radiofrequency key:
–the transponder in the key sends the following signals to the UCH:
– Key identifier signal.
– Immobiliser code signal.
The transponder is also involved in the Immobiliser function.
The radiofrequency key is used to transmit the key identifier information after pressing the button once. A
radiofrequency wave is sent to the UCH to carry out the user's request if the key is allocated to the vehicle (locking
or unlocking the doors and the tailgate).
Injection
When the authentication messages with the UCH have been exchanged, the injection can be unlocked and
authorise the starting of the engine.
The injection system is unlocked and engine starting is authorised as soon as the UCH has authenticated the
injection computer.
Electric window:
The driver has a one-touch electric window: a short press of the lowering button gives one-touch window lowering.
Another press stops the initial movement.
The passenger has a standard electric window.
CPE*: electric central door locking.

Layout of the Access - Safety function
Access (RF*) and protection (engine immobiliser system) of the vehicle:
The access function (locking/unlocking) is provided by the UCH and the key.
Communication between the key and the UCH is made via radio frequency transmission at 433 MHz.
When the switch is pressed, the key sends out a radiofrequency wave signal. The UCH receives the signal via its
built-in aerial.
The UCH authenticates the key and carries out the user's request if the key is allocated to the vehicle.
