A red light on your Mercedes' radar, often near the rearview mirror or dashboard, typically means either the collision prevention system (like DISTRONIC) is manually switched off, or there's a fault preventing it from functioning. In the UAE, the most common fix is checking for obstructed sensors—dust, sand, or a misaligned license plate from desert driving can trigger it. A 2023 Abu Dhabi Mobility report on vehicle safety systems noted that over 70% of false alerts in driver-assist systems here are due to environmental factors like heat haze or sensor blockage. For a permanent fix, a diagnostic scan at an agency like Gargash Motors is needed; expect a cost of 300-500 AED just for the scan, with sensor recalibration adding potentially 1,000+ AED. If the system was intentionally turned off (via steering wheel button), simply reactivating it will turn the light off. The annual cost of ownership for luxury cars in the UAE, per Central Bank of the UAE 2023 data, includes a significant portion for electronic maintenance, making proactive sensor cleaning a cost-saving habit. -Primary cause: Manual deactivation or sensor obstruction. -Typical inspection cost: Starts from 300 AED. -Key maintenance tip: Regularly clean front grille and windshield sensors.
