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 7 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.
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.
DRIVER INFORMATION DISPLAY
The DID (Driver Information Display) is located in
the center of the instrument cluster. It displays
digital gages, main menus and submenus that
provide necessary and important information to
the driver. The information available to the driver
depends on vehicle configuration, and whether
the vehicle is in operation or parked. For the list of
the available menus and submenus, refer
to"DRIVER
INFORMATION DISPLAY (DID)
MENUS " in Section 5 Other Features.
