operated, operation sounds and
vibrations may be generated from
the brake system, but this is not a
malfunction.

vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when

■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.

erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
