I recently purchased a 2006 F430 Spider. On page 84 of the manual there is sidebar under the caption While Driving that states: "After driving in SPORT or RACE mode, let engine idle for several minutes before stopping it in order to stabilize temperatures." When I asked the sales consultant about this he really didn't know what this warning was about. The last few miles to my home are in a 25 MPH zone and I come thru at very low rpm's anyway. Alternatively, is switching to "Low Grip" mode for a few minutes sufficient? Can someone enlighten me on how important this is?
