Service engine soon: Illuminates
when the ignition is first turned to
the on position to check the bulb
and to indicate whether the vehicle
is ready for Inspection/Maintenance
(I/M) testing.
Solid illumination after the engine is
started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction.
WARNING: Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Speed control (if equipped):
Illuminates when the speed control
system is engaged. Turns off when
the speed control system is
disengaged.
Stop engine (diesel engine only):
This red lamp illuminates when the
engine needs to be stopped (as soon
as it can be safely done). If the 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.
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 in the Driving chapter of this owner guide and/or your engine
operator's manual.
Refer to your engine operator's manual for specific information regarding
this feature. Drivers of electronically-controlled engines should know the
extent of warning engine shutdown system before operating the vehicle.
