Changing The Engine Air Filter - Lincoln NAUTILUS 2022 Owner's Manual

If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N).

coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.

cool. Check the coolant level.
4. If the coolant level is at or below the
minimum mark, add prediluted coolant
