Functions and Activation Conditions for Lane Departure Warning (LDW)

The Detroit Assurance LDW system is designed to warn the driver if the vehicle crosses the outer boundary of the lane marking without the turning signal being set. 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.

In addition to acting as a warning, lane markings on the driver display screen show the status of LDW. No lane markings or outlined lane markings indicate the LDW is off. Solid white or red lane markings indicate LDW is active.

LDW only issues warnings if the speed is above approximately 37 mph (60 km/h).

When driving over lane markings unintentionally, the volume of audio equipment like the radio and/or hands-free systems is muted and a direction-related ‘rumble-strip noise’ sounds from either the left or right door speaker.

LDW does not issue a warning if:

• the turn signals are switched on;

• there is braking or acceleration; or

• a driving safety system such as Active Brake Assist (ABA), Stability Control, or Adaptive Cruise Control (ACC) intervenes.
