If Slow to Calibrate
2020 GMC Acadia SLSECTION If Slow to Calibrate
WARNING: This page is about a different car, the 2021 GMC Acadia. However, it is still accessible from the selected car via links, so may be relevant.
The ideal calibration condition is driving on a freeway or two lane road with medium traffic. One or more of the following conditions may increase the length of time required to complete the self-calibration procedure:
- Visually inspect for damaged, bent, or broken Long Range Radar bracket. Brackets out of level more than 2 degrees will not calibrate or self-learn. Discuss with the customer about vehicle history and possible past accident. Replace bracket if damaged.
- Heavy traffic - following too close behind vehicles for long periods (more than 40 min)
- Stop and go or very slow traffic
- Mountain roads
- Constant sharp curves in roadway
- No traffic - if no traffic is available, may need to add vehicle ahead to support calibration
- Limited or no stationary structures on side of the road - need structures such as street signs, guard rails, mail boxes, parked cars, etc.
- Driving in tunnels
