Functions and Activation Conditions for Lane Departure Warning
Warning: The LDW system is intended only as an aid for a conscientious and alert driver. Do not rely solely on the system to safely operate the vehicle.
The system may not indicate lane departures under certain conditions. Read the information in this manual to understand the circumstances under which this system may not provide adequate lane departure warnings.
The system does not provide warnings for all possible hazards. LDW is not a substitute for safe driving procedures and cannot prevent an accident if the driver is impaired or not driving safely.
Failure to use the system properly could result in personal injury and/or death and severe property damage.
The Detroit Assurance LDW system is designed to warn the driver as the vehicle crosses the outer boundary of the lane marking. This may differ from other LDW systems which issue a warning as the driver approaches the inside of the lane marking. If the system warns at, or just beyond the outer edge of the lane marking, the system is performing as designed. If the warning does not occur, or occurs after an excessive lane departure, the system may not be operating properly.
Lane departure warning only issues warnings if the speed is above approximately 37 mph (60 km/h).
The lane markings on the driver display screen show the status and state of LDW:
-
No lane markings indicate that LDW is off.
-
Outlined lane markings indicate that LDW is not ready.
-
Solid white markings indicate LDW is on and ready to issue warnings.
-
Red lane markings indicate a lane departure is occurring; red lane markings are a visual warning from the LDW system.
In addition to the visual warning, when driving over lane markings unintentionally, the volume of audio equipment like the radio and/or hands-free systems is muted and a "rumble-strip noise" emits from the side of the vehicle driving over the lane markings.
LDW does not issue an audible warning when:
-
the turn signals are switched on
-
if the driver is braking or accelerating
-
if the driver is making a sharp turn
-
if a driving safety system such as ABA, stability control, or ACC intervenes.
