Wiring diagramDriving on snowy and icy roads
When operating the Subaru Ascent on snow-covered or icy roads, it is essential
to adopt smooth and controlled driving techniques. Sudden braking, rapid acceleration,
high speeds, or sharp steering inputs can easily lead to skidding or loss of traction,
especially in low-grip conditions.
