STOP Telltale light
In the event of a serious fault, the red STOP
telltale light comes on and an audible alarm will
sound if the engine is running. An illuminated
stop message light indicates a serious problem
has been detected, and the driver must respond
immediately to the problem.
When illuminating, this telltale light means the
vehicle must be safely pulled off the road and
stopped. In some instances, the engine must be
switched off immediately.
WARNING
Failure to stop and take necessary action
when the STOP telltale light is on can result in
automatic engine derate and shutdown.
In some cases preventive action may be taken
by the engine ECU to protect the engine. For
further details, refer to “Engine Protection
System” in
Starting and Stopping Procedures .
CHECK Telltale light
This telltale light means that a fault or an
abnormal operating condition has been
detected. The vehicle must be checked at the
next stop.
If the CHECK telltale light illuminates, an
associated message is displayed in the DID.
Always pay attention to the associated
messages (see “Acknowledging Messages”
below).
INFORMATION Telltale light
The INFO indicator light comes on when there is
a new information message or an abnormal
status is detected by the electronic control unit.
A pictogram or text or both are shown in the DID
in addition to the INFO telltale light (see
“Acknowledging Messages” below).
Acknowledging Messages
A fault message associated to a STOP, CHECK
or INFORMATION telltale light must be
acknowledged by pressing the ESCAPE or
ENTER button after which the display returns to
the same status that existed before the fault
occurred. All messages can be acknowledged.

DID menu. Refer to
Other Features for more
