The lane change signal only flashes three times on my 2012 Suzuki Kizashi, which I don't think is enough. The owner's manual says that it can be "customised" to flash 4 times, but I would need to take it to an authorised dealer. For such a simple thing I should be able to do it myself if I knew how. Any ideas how to increase the number of flashes?
Take it to a dealer and have them do it.
