Buick Enclave: Drive Systems
All-Wheel Drive
Vehicles with this feature always send engine power to all four wheels. It is
fully automatic, and adjusts itself as needed for road conditions.
When using a compact spare tire on an AWD vehicle, the system automatically detects

To restore AWD operation and prevent excessive wear on the system, replace the
compact spare with a full-size tire as soon as possible. See Compact Spare Tire
