How to calibrate the ACC on Emgrand?

[Alexis]

Emgrand ACC calibration requires specialized calibration tools and professional skills, and cannot be performed by yourself. If calibration is needed, it is recommended to take it to a 4S dealership. More information about the Emgrand ACC is as follows: 1. With ACC normally activated, adjust the speed by toggling the speed adjustment button. Speed adjustment: Each toggle increases or decreases the speed by 1Km/h. 2. With ACC normally activated, toggle the DIST+/DIST- buttons to adjust the safe following distance between your vehicle and the vehicle ahead. 3. With ACC normally activated, press the ACC off button on the steering wheel to exit the ACC function when you are done using it.

Regarding the ACC calibration for the Emgrand, I've done quite a bit of research myself and believe the key is to ensure the system's sensors are functioning properly. Typically, you need to start the engine, then navigate to the driving assistance options in the settings menu, and select ACC reset or calibration. After that, drive at a constant speed on a straight, open road for a few kilometers to allow the radar to automatically adjust distance detection. During the process, remember to check if the front bumper sensors are clean and not obstructed by dirt. If the ACC frequently malfunctions or responds with delays, the camera or radar might be misaligned, requiring professional calibration at a 4S shop using specialized tools. This is crucial for automatic braking and follow-up functions—don't take it lightly. I once almost rear-ended another car due to not calibrating in time.

As a long-time Emgrand owner, ACC calibration is actually quite simple. First press the ACC button on the steering wheel to enter the menu, select calibration mode - it usually prompts you to drive above 40km/h on flat road for a few minutes for automatic calibration. If it shows failure, better restart the dashboard system and check wiring connections. I generally recommend doing initial calibration when getting a new car to prevent deviation, plus regular sensor cleaning to avoid dust interference. ACC is convenient but miscalibration may cause speed misjudgment - routine maintenance saves more trouble than post-failure repairs.

Personal opinion suggests that the ACC calibration for the Emgrand is best left to professional technicians, as the system calibration relies on specialized tools. I've seen many cases in the workshop where ACC malfunctions are mostly due to radar module misalignment, requiring connection to an OBD diagnostic tool to reset parameters, including adjusting distance and speed thresholds. Owners attempting it themselves may find it ineffective and a waste of time. Calibration is urgently needed only after accidents involving part replacements or frequent false alarms. During the operation, technicians first check on a test bench before fine-tuning on the road, with the entire process taking no more than half an hour. The cost is not high, making it worthwhile to spend a little money to ensure safety.

When it comes to ACC calibration in the Emgrand, here's how I understand it in simple terms: it's about enabling the car to accurately measure distances to maintain safe cruise control. The straightforward method is to check the steps in the vehicle manual—usually, you select settings in the infotainment system, then adjust the driving assistance mode, and follow the prompts to drive at a steady speed for calibration. If calibration fails, head to the 4S store—never force it. I've used it once myself, and after calibration, following other cars became smoother. This feature is quite smart but can be affected by weather; in rain or fog, you should check it more frequently to prevent minor issues from escalating into dangers.
