If the key is left in the luggage compartment/boot with all doors locked and the liftgate/boot lid closed, a beep sound is heard for about 10 seconds to remind the driver the key has been left in the luggage compartment/boot. If this happens, open the liftgate/boot lid by pressing the electric liftgate/boot lid opener and remove the key. A key removed from the luggage compartment/boot may not function because its functions may have been temporarily suspended. To restore the key function, perform the applicable procedure (Search).
