Do
  not   repeatedly   press   the   buttons   of   your   remote   control   out   of   range   and   out   of   sight   of   your   vehicle.   You   run   the   risk   of   stopping   it   from  
w

The
  remote   control   does   not   operate   when   the   key   is   in   the   ignition,   even   when   the   ignition   is   switched   off.
Locking the vehicle
Driving with the doors locked may make access to the passenger compartment by the emergency services more difficult in an emergency.
A s   a   safety   precaution   (with   children   on   board),   remove   the   key   from   the   ignition   or   take   the   electronic   key   when   you   leave   the   vehicle,   even   for  
a

  short   time.

The
  CITROËN   dealer   will   be   able   to   retrieve   the   key   code   and   the   transponder   code   required   to   order   a   new   key
Do
  not   throw   the   remote   control   batteries   away,   they   contain   metals   which   are   harmful   to   the   environment.

  them   to   an   approved   collection   point.
When purchasing a second-hand vehicle
Have the key codes memorised by a CITROËN dealer, to ensure that the keys in your possession are the only ones which can start the vehicle.
