within 3 seconds to activate the test mode. This test
can be done when the engine is not running providing
that the battery charge is sufficient (above 24.0
volts).
The telltale panel alarm emits a sound each second
to remind that the test mode is in progress.
NOTE
Lighting test mode can also be initiated and
stopped using the DID menu “Exterior Lamp

"DRIVER INFORMATION DISPLAY" on page39
in Section 5 Other Features.

To stop the test mode, pull up the multi-function lever
once or turn the ignition OFF or remove the parking
brake.

The test mode is useful to check the operation of
the multiplex outputs and the exterior lights. It
doesn't test the functionality of the commands

be checked before. Once these commands tested,
activate the test mode to check the exterior
lighting.

illuminates. Press the headlights rocker
switch in second position and confirm that the

corresponding cluster telltale light illuminates.

STOP telletal light illuminates
Once these commands tested, activate the test
mode to check the exterior lighting by pulling up the
multi-function lever 3 times within 3 seconds.
