I went to start my 06 650 v2 ( about 15 degrees outside) very difficult to start. Any in the process of finally getting it to start my belt indicator light flashed ,on 2 different occasions. I was trying to start it in neutral.

 

i have an 06 400 and mine did the same a few weeks after i bought it last year. it was real cold. the dealer told me could have been water messing with the sensor. or just the cold messing with it it hasnt done it since and they checked it out just to make sure there were no issues. if its still under warranty bring it in why stress about it.it will probably be nothing
