Handling the car can be a little difficult task particularly in winter.

To avoid the freezing of doors and locks, apply some silicone spray around the trunk. Use some general purpose lubricants for the doors and locks. You can also use some dry lubricants coming in tubes for the latches. Lithium grease in small tubes is also a preferred solution. Use ice scarpers inside the car. Try to use a 50% anti-freeze with a 50% water mixture as a coolant for your car. Give special attention on the electrical system including battery since the battery falls when the temperature falls.
