Yeah, my dumbass has done that before at night while I wasn't paying attention to the engine temperature. I thought my car was fucked up.
In order for lift to function, your temperature has to go up two clicks from the lowest position. It's kind of a safety function so that the engine is warm before lift is engaged, making the stress easier on the engine due to the fact that it's warm and the oil is thinner.
EDIT: I believe that the temperature has to go up at least two clicks. It's either two or one, but I'm almost positive that it's two.
with the old lift bolts ('00-'2) you have to have the temp up two clicks as you said.
with the new lift bolts--you can hit lift w/no warmup whatsoever..even though i would recommend warming up anyway..running your engine hard when it's 'cold' is never a good idea, in my opinion.
