What should you do to get a car running that hasn't been driven in one year?

To get a car running that hasn't been driven in a year, start by checking the battery; it may need a jump-start or replacement. Inspect the tires for flatness and proper inflation, and check the fluid levels, including oil, coolant, and brake fluid, topping them off as necessary. Look for signs of leaks or corrosion, and consider changing the oil and replacing the fuel if it's old. Finally, ensure all lights and signals work before attempting to drive it.
