Keep your gas tank at least half full to avoid gas line freeze-up and ensure that you have extra running time.
If door locks are frozen, be sure to warm the key or use a lock de-icer. Never combine heat with lock de-icer as it is flammable. Don't pour warm water on the car as it may re-freeze making the situation worse; warming your key first will help heat up the lock from the inside.
Warm up car for 10 minutes
Warm up your vehicle for at least five to 10 minutes before heading out. Warming your vehicle allows oil and engine to warm up, as well as the heat and defrosting systems.
Avoid parking brake if possible
When you get to your destination, try to park in a garage. Also, if possible, avoid using your parking brake in below freezing weather as it may freeze in the locked position.
