PRECAUTIONS
The LCA1224 is for emergency warning only. It warns of sudden loss of coolant while the vehicle is
operating. It will provide an indication when gradual loss has reached the low level, but should not be
used to avoid regular visual checking of the cooling system. The cause of any loss of coolant should be
investigated rather than just using the LCA1224 as a reminder to top it up.
