Customer states:
 The coolant warning lamp appears in the instrument cluster.

down and heats up. If the coolant circuit is incorrectly filled or bled, this can lead to sporadic illumination of the low
coolant level warning lamp.

Not applicable.
Service
When processing this concern, follow the points below:
 The coolant level in the coolant expansion tank must be adjusted/checked in cold conditions according to the
Elsa repair manual.
