How fail-safe cooling works

If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs:
• the engine coolant temperature
gauge will move to the H (hot)
area
• the
symbol will illuminate
• a tone will sound 3 times
• the service engine soon light will
illuminate
If the engine coolant temperature
exceeds 166°C (330°F):
• the
symbol will begin to
flash
• a tone will sound 5 times
• the service engine soon light will
remain on
• the coolant temperature gauge
remains on H (hot)
• the engine will shut down.
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.
