How fail-safe cooling works
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, the engine coolant temperature gauge will move into
the red area, the
, and the service engine soon lights will
illuminate.
The vehicle will still operate, but will have limited engine power and no
air conditioning capability.
Continued operation will increase engine temperature and cause the
engine to completely shut down. The vehicle will coast to a stop.
As the engine temperature cools, the engine may be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
• Pull off the road as soon as possible.
• Immediately turn the engine off to prevent severe engine damage.
• Wait for the engine to cool.
• Check the coolant level.
