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.
Access via radiofrequency:

Engine immobiliser
The immobiliser function is divided between three coded computers (the UCH, the injection computer and the key).
The key and the UCH are linked by a magnetic field which is created by the transponder ring.
When the + After ignition is switched on, the key sends its identifier to the UCH via the transponder ring, located on
the ignition switch. The UCH runs through an authentication procedure with the key via the transponder ring. If the
key is allocated to the vehicle, then operation of the starter motor is authorised and the injection system is unlocked.
The injection computer has no reference code in its memory: the code which is transmitted is stored.
If the key code and the UCH code do not match, the system remains locked. The red engine immobiliser warning
light flashes (quickly). The vehicle cannot be started.
If the anti-theft tracking unit is fitted to the vehicle and the does vehicle not start, the customer should be asked the
following questions. This is to ensure that the information given by their access supplier via GSM conform with what
is noted in the computer:
– Who is your vehicle detection service supplier?
– Which activation option did you choose? (with locating system/without locating system)
– Did you request remote blocking? (If yes, this is why the engine does not start).
If the vehicle detection service cannot be activated, ask the owner:
– What is the server name of the vehicle detection service supplier?
– What is the APN address of the vehicle detection service supplier?
This is to ensure that the information given by their access supplier via GSM conform with what is noted in the
computer.
Recognition of keys in normal operationIMPORTANT
When the vehicle battery has a low charge, the drop in voltage caused by operating the starter could reactivate the
immobiliser. If the voltage is too low, the engine cannot be started, even by pushing the vehicle.

Locking / Unlocking
This system can function with up to four remote control units (the UCH can only manage four different codes).
The radio frequency signal receiver is integrated in the UCH.
The central door locking button is inhibited once the doors have been locked by the remote control.
Locking and unlocking the doors with the remote control is confirmed by the hazard warning lights flashing (if all the
doors are closed properly):
– locking: 2 flashes,
– unlocking: 1 flash.
Depending on the equipment level, unlock the doors and ensure that none of the doors is opened within the next
30 seconds otherwise the system will automatically re-lock the vehicle opening elements (without the hazard
warning lights flashing).
The UCH controls the vehicle interior lighting. If a courtesy light is left on, the UCH will cut the lighting supply after
a period of approximately 30 minutes.
The Top of the range version dims the light progressively after the doors have been closed by radio frequency
remote control.
Spare keys are supplied without a code or a number.
It is possible in the event of a key being stolen or lost or at the customer's request, for a vehicle key to be de-
allocated.
It can be reassigned to the same vehicle if necessary.Note:
Unlocking can be performed by the UCH, if the airbag computer has detected an impact or if it is faulty (see 88C,
Airbag - Seat belt pretensioners).
