GMC Terrain 2018-2026 Owners Manual / Driving and Operating / Cruise Control / Setting Adaptive Cruise Control / Weather Conditions Affecting ACC

If the interior temperature is extremely high, the instrument cluster may indicate that ACC is temporarily unavailable. This can be caused by extreme hot weather conditions with direct sunlight on the front camera. ACC will return to normal operation once the cabin temperature is lower.
