Auto door locks on 06 xc90
 

Can anyone please tell me how to set the auto door lock feature for my 2006 XC90?
The owners manual is useless. Also how do I know when I need an oil change? Just bought the vehicle 7 days ago. Thanks in advance for any help.

I wanna say that you turn the key to the last position w/ out turning on the car, make sure its showing no messages, and hold down the lock button until it says auto lock on

Sounds like you have no records on the last/past servicing of the car, therefore you need an oil change (and probably all filters & fluids, including tranny) NOW.

Start with a clean slate so that you know what's been done when.
