will cause the LED in the control button to blink and then
turn off.

Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to "Maintenance Procedures" in Section 7 of this manual
for proper coolant selection.
