Driver alert warning
Description

Operation
Applies to: vehicles with traffic light information
Within the limitations of the system, the driver
alert warning informs the driver if a break is
needed.
Turning traffic light information on or off
You can turn the traffic light information on or
off in the Driver assistance menu ðpage 142.
After starting to drive, the driver alert warning
analyzes the driving behavior and uses this data
to assess drowsiness. This assessment is continu-
ously compared with the current driving behav-
ior.
Accessing traffic light information

Select in the instrument cluster: vehicle func-
tions tab > Traffic signs.
If this comparison suggests that the driver is
drowsy while traveling at speeds of 40 mph (65
km/h) or above, then the system will recommend
a break. This suggestion will be provided by
means of a display in the instrument cluster. If
high levels of drowsiness are detected, there will
also be an audio signal.
Tips
If another tab or another function is selected
in the instrument cluster, the traffic light in-
formation will appear in the status bar on the
instrument cluster.
