Activating or Deactivating Lane Departure Warning (LDW)

57x d 05.03.003

When the engine is turned on, LDW is automatically activated.

Note:  There is no audible self-test of the ‘rumble-strip noise’ of the LDW when the key is turned on.

Pressing the physical LDW OFF switch will deactivate LDW for fifteen minutes. See Fig. . When the LDW is deactivated, the switch will illuminate.

A driver might want to turn off LDW on winding roads or when driving through construction zones or other areas where lane markings are not clear.

Note:  Vehicles equipped with D.A. 5.0 and an MPC2 camera, but no LDW system may have a permanently illuminated LDW OFF switch as LDW has been disabled.

LDW is not active if:

  • the driver presses the LDW OFF switch; or

  • the system is searching for a lane.

If there is a system error, the LDW telltale will illuminate in the driver display. See Fig. .
