or more distance segments will illuminate,
depending on the distance. When the
eighth distance segment illuminates, you
have reached the minimum distance.

warning will sound as the first red dis-
tance segment illuminates and a con-
stant acoustic warning lasting a
maximum of 2 seconds will sound for
the second distance segment. The sig-
nal is canceled when the gear selector
lever is placed in position P or the park-
ing brake is set.
Rear area: An intermittent acoustic
warning will sound when the first dis-
tance segment illuminates. This signal
quickens with each additional distance
segment lit. When the eighth distance
segment illuminates, the acoustic
warning becomes a constant signal.
