No Turn on Red function
Principle
The No Turn on Red function assists the driver
by indicating at which traffic lights turning on
red is prohibited.
To do so, this function analyzes traffic lights
and traffic signs using the camera behind the
windshield. In addition, the navigation system
data is used.
Safety information
Follow the safety information in the "Forward
Collision Mitigation" chapter.
Functional requirements
The following functional requirements apply to
the No Turn on Red function:
▷ The system detects the right-of-way situa-
tion ahead by analyzing traffic lights and
traffic signs.
▷ Vehicle is less than approx. 164 ft/50 m
from the traffic lights.
Sensors
The No Turn on Red function is controlled by
the camera behind the windshield.
Display in the instrument cluster
If the driver approaches a red traffic
light with a traffic sign that prohibits
a turn on red, an indicator light is dis-
played on the instrument cluster.
The indicator light goes out automatically after
you drive off at a speed greater than approx. 9
mph/15 km/h.
