— light flashes rapidly (1 Hz); pointer on the right
Note
The temperature warning in point three is indicated if the conditions "engine coolant temperature too high" and "engine coolant level too low" are present simultaneously
(1Hz = 1 flash per second. 0.5Hz = 2 seconds per flash)

Mine is definitely always lit, I can't see why it would, since it is lit up as soon as you start the car and the coolant temp is ambient temperature. The level may be a tad low, but it's above the min mark? I'll top it up to max and see what happens
