The 2020 Lexus GX's Lane Keeping Assist helps maintain lane position by providing steering assistance when drift is detected. When this feature shows as off, understanding its operation and requirements helps restore functionality.
GX Lane Keeping Assist
The GX's lane keeping features are part of Lexus Safety System+. The system monitors lane markings and can provide warnings (Lane Departure Alert) and steering assistance (Lane Keeping Assist). Both features use the forward-facing camera.
Why Lane Keeping May Be Off
Several conditions cause lane keeping to show as off. Manual disable through settings turns off the feature. Camera obstruction from dirt or weather causes system disable. Speed below operating threshold (typically 32 mph) keeps feature inactive. System faults force the feature off with warnings.
Checking and Enabling the Feature
Use the GX's settings menu to verify Lane Keeping Assist status. Navigate to the driver assistance or safety settings. If the feature is disabled, enable it. If enabled but showing off during driving, conditions or a fault is preventing operation.
Terrain Mode Considerations
The GX's off-road focused design includes terrain modes. Certain off-road or low-range modes may disable lane keeping as it's not appropriate for off-road use. Verify the vehicle is in normal on-road mode when testing lane keeping.
