Chevrolet Silverado: Driver Assistance Systems / Lane Departure Warning (LDW) (2500/3500 Series)

Chevrolet Silverado 2019-2024 Owners Manual / Driving and Operating / Driver Assistance Systems / Lane Departure Warning (LDW) (2500/3500 Series)

If equipped, LDW may help avoid crashes due to unintentional lane departures. LDW uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or greater. It may provide an alert if the vehicle is crossing a lane without using a turn signal in that direction. LDW light will not alert if the turn signal is active in the direction of lane departure, or if LDW detects that you are accelerating, braking or actively steering.


The LDW system does not steer the vehicle. The LDW system may not:

  • Provide enough time to avoid a crash.
  • Detect lane markings under poor weather or visibility conditions. This can occur if the windshield or headlamps are blocked by dirt, snow, or ice; if they are not in proper condition; or if the sun shines directly into the camera.
  • Detect road edges.

Detect lanes on winding or hilly roads.

If LDW only detects lane markings on one side of the road, it will only warn you when departing the lane on the side where it has detected a lane marking. Always keep your attention on the road and maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LDW in bad weather conditions.

How the System Works

LDW utilizes a camera sensor installed on the windshield ahead of the rearview mirror to detect lane markings.

To turn LDW on and off, press @ on the instrument panel to the left of the steering wheel. The control indicator will light when LDW is on.

When LDW is on, is green if LDW is available to warn of a lane departure. If the vehicle crosses a detected lane marking without using the turn signal in that direction, changes to amber and flashes. Additionally, there will be three beeps, on the right or left, depending on the lane departure direction. LDW will not alert if the turn signal is active in the direction of lane departure or if LDA detects that you are accelerating, braking or actively steering.

When the System Does Not Seem to Work Properly

The system may not detect lanes as well when there are:

  • Close vehicles ahead.
  • Sudden lighting changes, such as when driving through tunnels.
  • Banked roads.

If the LDW system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help.

LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road imperfections. This is normal system operation; the vehicle does not need service. Turn LDW off if these conditions continue.
