If the message is still displayed when you switch
the vehicle back on, drive to a qualified workshop
soon and have the fault rectified.
The traffic light information function tells you
the speed at which you need to travel to reach
the next traffic light on green 1 . It also informs
you how long you will be waiting at the next red
light 2 . The traffic light information is shown in
the instrument cluster and head-up display as
soon as traffic light data is available. If certain
system limits are reached, the speed recommen-
dation or the waiting time at a red traffic light
cannot be shown and a grey traffic light symbol
3 is shown instead. This is the case if the dis-
tance to the traffic light is less than 30 metres,
for example.
Traffic light information
Introduction
Within the system limits, the traffic light infor-
mation function helps to reduce stop-start traffic
and improve the flow of traffic. For this purpose,
you are shown the ideal speed at which to travel
so that you reach the next set of traffic lights
when they are green.
