STOP, CHECK AND INFORMATION
TELLTALE LIGHTS

STOP and CHECK 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
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 section.

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).

ACKNOWLEDGING MESSAGES

A fault message associated to a STOP or
CHECK 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. 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 gauges, main menus and sub-menus 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 sub-menus, refer to
“Driver Information Display Menus” in OTHER
FEATURES section.
