The Dynamic Radar Cruise Control (DRCC) system on the 2020 Lexus RX 350 is an advanced feature designed to enhance driving comfort and safety. By automatically adjusting your vehicle’s speed to maintain a safe distance from the car ahead, DRCC helps reduce driver fatigue on long journeys.

How Dynamic Radar Cruise Control Works

DRCC uses radar and camera technology to detect vehicles in front of you. When activated, it maintains a preset speed but will automatically slow down or accelerate to keep a safe following distance. This adaptive functionality is especially helpful in stop-and-go traffic or highway driving.

Maintaining Your DRCC System

  • Keep Sensors Clean: The radar sensor is typically located behind the front grille. Dirt, snow, or debris can obstruct its function, so regular cleaning is essential.
  • Update Vehicle Software: Lexus occasionally releases software updates that improve system performance. Check with your dealer or service center regularly.
  • Monitor Warning Indicators: If the system detects an issue, a warning light or message will appear on your dashboard. Address these promptly to ensure continued safe operation.
  • Professional Inspection: During routine maintenance, request a DRCC system check to confirm everything is functioning as intended.

Safety Tips When Using DRCC

While DRCC provides substantial assistance, always remain attentive and ready to take control. Weather conditions such as heavy rain or fog can impair sensor performance. Use the system as a supplement to your driving, not a replacement.
