*1 The next message after a Speed Mode message will decide how a "x 0 x x 0 1 0 1" message is processed:
• If, after a Speed Mode change, a Travel Mode message follows, all occurrences of "x 0 x x 0 1 0 1" messages are processed as
Deceleration Mode messages.
• If, after a Speed Mode message, a "x 0 x x 0 1 0 1" message follows, this and all other messages are processed as Remaining
Distance Mode messages.
