GMC Terrain: Lane Departure Warning (LDW) - Object Detection Systems - Driving and Operating - GMC Terrain Owner's ManualGMC Terrain: Lane Departure Warning (LDW)

For vehicles with this feature, read the entire section before using it.

WARNING

The LDW system does not steer the vehicle and is an aid to help the vehicle stay in the driving lane. The LDW system may not:

○ Provide enough time to avoid a lane change collision.
○ Be loud enough to hear the warning beeps.
○ Work properly under bad weather conditions or if the windshield is dirty.
○ Detect lane markings and will not detect road edges.

○ Warn that the vehicle is crossing a lane marking if the system does not detect the lane marking.

LDW will operate even if it only detects lane markings on one side of the road. It will not warn if the vehicle departs the lane from the side where it has not detected a lane marker. The vehicle position must be maintained within the lane or, vehicle damage, injury, or death could occur. Even with LDW, always keep your attention on the road and maintain proper vehicle position within the lane. Always keep the windshield clean and do not use LDW in bad weather conditions.

When the vehicle crosses a detected lane marking, the LDW indicator will flash and three beeps will sound. LDW will not warn if the turn signal is on or if a sharp maneuver is made.
