From the highest risk level to the lowest risk level,
the system will sound an audible alert, and display a
message, as shown in
Fig. 2.30
.
Trip/Leg Totals
The driver message center records the number of
messages received, and displays the number of
messages as counts. Roll stability advisor (RSA) and
hard-braking event data (HBED) counts can be
viewed in the trip advisory screen, and the leg advi-
sory screen.
Counts can be reset using the + key on the steering
wheel. Clearing RSA and HBED leg counts will also
reset the leg miles and leg hours. Clearing RSA and
HBED trip counts will also reset trip miles, trip hours,
leg miles, leg hours, and leg advisory counts. In ad-
dition, resetting leg miles will clear leg counts. Clear-
ing trip miles will reset miles, hours, and counts in
both the leg and trip screens.
The TRIP and LEG advisor screens count both the
roll stability advisories (ROLL) and hard-braking
events (BRK). For example, if during a TRIP, the
driver message center recorded the events in
Table 2.5
, the message center would display as
shown in
Fig. 2.31
.

that the count has exceeded 9 counts. See
