How fail-safe cooling works
Standard cluster
Optional cluster
If the engine overheats, the engine will automatically switch to
alternating cylinder operation. Each disabled cylinder acts as an air
pump and cools the engine.
When this occurs:
if your vehicle is equipped with analog gauges, the engine coolant
temperature gauge will move to the H (hot) area
if your vehicle is equipped with digital gauges, the engine coolant
temperature gauge will illuminate all eight bars and a tone will sound
every five seconds for a minute
the

indicator light will illuminate.
The vehicle will still operate, however:
the engine power will be limited.
the air conditioning system will be disabled.
