Remote control  
Use this procedure in the following situations:  
– Remote control battery discharged.  
– Remote control malfunction.  
– Vehicle battery discharged.  
– Vehicle in an area subject to strong  
electromagnetic interference.  
In the first case, change the remote control  
battery.  
The remote control is a sensitive, high-  
frequency device; avoid handling it in your  
pocket, due to the risk of unintentionally  
unlocking the vehicle.  
Avoid pressing the remote control buttons  
while out of range of the vehicle, due to  
the risk of rendering the remote control  
inoperative. It would then be necessary to  
reset it.  
If one of the doors or the boot is still  
open, central locking will not take  
place.  
However, if the vehicle is fitted with an  
alarm, it will be activated after 45 seconds.  
In the second case, reinitialise the remote  
control.  
Refer to the corresponding sections.  
The remote control does not work when the  
key is in the ignition switch, even when the  
ignition is switched off.  
If the vehicle is unlocked but the doors  
or boot are not subsequently  
opened, the vehicle will automatically lock  
itself again after about 30 seconds. If the  
vehicle is fitted with an alarm, it will be  
reactivated automatically.  
Anti-theft protection  
Do not modify the electronic  
vehicle immobiliser, as this might result in  
malfunctions.  
For vehicles with a key ignition switch,  
remember to remove the key and turn the  
steering wheel to engage the steering lock.
