The one with the "S"
badge in it is the only part that removes seperately..
To remove the grill with the S, you first remove the cover on top of it, which is only clipped in place, then under that your find a single screw in the top of the grill, remove this.
Once that screw is removed you need to get your fingers or a small screw driver behind the grill and using the tool or your finger, pull the "click tabs" on the back of the grill, there are four, two at the top, two at the bottom.
I suggest unclipping/releasing the bottom two tabs first, then the grill will pull out if you pull at the right angle.
Hard to describe, but once you look behind the grill your understand what you need to do.
