Dropped Something in Area Next to Parking Brake Handle?

I have the same problem as the issue described here, only with a different make and model of car:

I'm having trouble applying to my make and model of car the instruction on removing the plastic housing that were described at the link.

Advice for my particular make and model would be much appreciated. Thank you.
