Check the Glovebox. Make sure your owners manual, proof of insurance, and registration card are present and easily accessible.
Check the tires. Get a penny and slide the penny's edge with Lincoln's head pointing down, in one of the grooves of the tire. If you can see the space above Abe's head, you need new tires. If not the threads are good and all you have to do is check the air pressure next time you get gas.
Check the spare tire. Make sure the spare is fully inflated and that the jack, wrench, and tire-changing bits are in the trunk.
If your car has wheel locks, make sure you have the adapter for the lock-nut.
If your car is due for recommended service, call European Motors to schedule an appointment. Booking your appointment 4 weeks before your trip is ideal in case your car needs any major repairs.
