Is it safe to drive?

What to do
- Drive at a steady highway speed for about 15 to 20 minutes: this usually lets the filter clean itself.
- Short trips only? That is the most common reason the filter clogs.
- If the light stays on, flashes or the car loses power, have it checked before the filter is blocked.
