Direction Indicators

The left or right warning indicator flashes in time with the corresponding left or right direction indicator lamps whenever they are operated. A warning indicator flashing twice the normal speed indicates that a direction indicator lamp bulb has failed (the message centre will indicate which bulb is faulty). If a trailer is connected and a rear indicator lamp bulb fails then the message will not be displayed. When the hazard switch is pressed, both warning indicators will illuminate in conjunction with the indicator lamps.

The Direction Indicator switches are interfaced to the Instrument Cluster (Z142) via the BeCM (Z238).
