Monthly 10-minute checks
- Tire pressure: use the number on the driver's door sticker, not the tire
- Tire tread: put a penny in the groove head-first. If you can see all of Lincoln's head, it is time for new tires
- Fluids: oil, coolant, brake and washer fluid levels
- Lights: headlights, brake lights and turn signals
- Warning lights: do not ignore a check-engine light
Follow the maintenance schedule
Your owner's manual lists when to change oil, filters, belts and fluids. Many newer cars can go 5,000 to 10,000 miles between oil changes. Changing it more often than needed wastes money, while skipping it can ruin an engine.

Frequently asked questions
How often should I change my oil?
Follow your owner's manual. Many modern cars recommend 5,000 to 10,000 miles, or less for severe conditions like short trips or towing.
Is it safe to drive with the check-engine light on?
If it is flashing, stop driving and get help, because it can mean a serious problem. If it is steady, get the code read soon.
