There are six lamps around the car to indicate direction changes. These are in the headlamps, tail lamps and on the side of the vehicle in front of the doors.

The turn signal lamps are operated using the left-hand control stalk.

To cancel the hazard warning signal flashers, where all the turn signal lights flash, press in the button for the hazard warning signal flasher. This is positioned in the middle of the dashboard by the center air vents.

The front and rear lamps are powered directly from the central electronic module (CEM).

A signal is also sent to the bulb in the hazard warning signal flasher switch when this function is activated.

The central electronic module (CEM) monitors the power consumption on each side to check for bulb faults. If the power consumption falls below a certain threshold value, a fault is indicated and the frequency of the signal to the bulbs is doubled on the side of the blown lamp.

There are diagnostics for the front and rear turn signal lamps.
