Hello everyone sorry if this was answered before I noticed the engine logo change when the engine kicks in it start as blue-silver color at first then after about two minutes it changes to gold color. I didn't find any info in the manual a friend told me that it shows the engine temperature status when it becomes gold means its warmed but this takes me to another question if its true which is should I warm up the engine first ? As u all know the prime doesnt warm up by it self like older models even it's not charged. Thank you very much
