STOP, CHECK AND INFORMATION TELLTALE
LIGHTS

STOP, CHECK and INFORMATION telltale lights

illuminate automatically to draw the attention of the
driver and their associated messages are displayed
in the DID. More than one message (see
"Acknowledging Messages" below) can be active at
the same time. A displayed message can be
replaced by a new message provided the new
message has a higher priority. Only fault codes that
have a direct impact on vehicle operation are
displayed. All fault codes are stored in the
appropriate ECU for access by service technicians.
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 an 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"
on page 5 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
"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. Acknowledgement of pop- up
messages and warnings stops the audible warning.
Acknowledged but inactive messages are displayed
again when the ignition key is turned to the START
position or they can be read in the DID menu. Refer
to Other Features for more information on the DID
menus.
