Display
Function

Turn signal indicator

ticking
Switching on the turn signal indicator is

indicated acoustically by the turn signal

indicator ticking. The driver's attention is

brought to a defect in the turn signal system

by the turn signal indicator ticking at a higher

frequency.

Turn signal indicator ticking is generated

electromagnetically. The frequency

corresponds to that of the turn signal indicator

lamp.

The signal comes from the combination relay

(turn signal indicator with trailer coupling, rear

window defroster), wiper motor, ATA (N10/2),

on model 210 from the multi-function control
module (N10-1) or from the driver-side signal-

acquisition and actuation module (SAM)

(N10/1), on model 163 from the All-Activity

Module (AAM, N10), on model 168 it is

generated by the integrated turn signal

indicator control in the instrument cluster (A1).

Parking brake reminderThe parking brake warning sounds when

terminal 15g is ON from a speed of approx. 5

km/h.

is available as a CAN message. It is

transmitted by the instrument cluster (A1).
