Stop engine: This light is used in
conjunction with the electronic
engine control. When illuminated,
the STOP ENGINE lamp indicates the need to stop the engine as soon
as it can be safely done.
If the STOP ENGINE lamp begins flashing, automatic engine
shutdown may take place in as little as 20 seconds.
WARNING: In the event of engine shutdown, make sure the
vehicle is safely off the road and the problem is remedied prior
to returning to the road. Failure to remove the vehicle from the road
could result in an accident, causing serious injury or death.
Refer to your engine operator's manual for specific information regarding
this feature.
If the engine shuts down, it can be restarted and operated for
30 seconds at a time or until the problem is corrected. For more
information, refer to Engine automatic shutdown warning light or
chime (if equipped) in the Driving chapter of this owner guide and/or
your engine operator's manual.
Drivers of electronically controlled engines should know the
extent of warning engine shutdown system before operating the
vehicle.
