gine has been activated. The engine ECU will derate
the engine, allowing it to run, but at lower rpm and
slower vehicle speed. The vehicle may be driven to a
safe location.
NOTICE
Because operating the engine when the red stop
engine light is illuminated can lead to severe en-
gine damage, the driver must move the vehicle to
a safe location as quickly as possible and shut
down the engine.
If the engine is shut down while the vehicle is in ser-
vice, a single restart attempt may be performed. De-
pending on the nature of the fault condition, a cool-
down period may be required before restarting. If,
upon restarting, the fault condition still exists the
lamp will come on and the engine should be shut
down. At this point, the vehicle is unsafe to drive and
should be transported to an authorized Freightliner
service facility.
