The ERS consists of three semi-active
automatic modes (T-1, T-2, and R-1)
and three manual setting modes (M-1,
M-2, and M-3). When an automatic
mode is selected, the SCU will adjust
the compression and rebound damp-
"
ing forces based on running condi-
tions. For all modes and models,
spring preload is physically adjusted
by hand. (See pages 5-40 and 5-43.)
For track modes T-1 and T-2, the fol-
lowing settings can be adjusted:
