Auto headlights: With lights OFF, ignition key at position 2, battery light on, no other - press button on left hand stalk for more than 2 seconds. There will be a "bong" confirming the operation.
Auto Wipers: Leave ring on R/H stalk one up from bottom. I may be that this option needs to be activated using a diagnostic tool, such as Examiner, Peugeot Planet 2000 or Lexia.
