Arrived home earlier and noticed the interior lights were on in the rangey.
Everything looked shut, so i got the key and locked it, and the dash booped and said "tailgate open".
Sure enough, the tailgate was shut, but not actually latched. Gave it a slam and locked it again and it happily locked and the lights went out.
Turns out the wife opened it at lunch time and got the pram out the back, mustnt have closed it properly.
But its left me wondering, shouldnt the interior lighting time out after 10minutes or so, so as not to drain the battery if a doors left open?!
