When parking your car on an incline, don’t rely solely on the parking brake. Engaging the door latch mechanism can provide an additional safety measure to prevent the car door from swinging shut.

  • Step 1: Before exiting the vehicle, pull the interior door handle while pressing the door against your leg.
  • Step 2: This action engages the latch, keeping the door open securely.

Remember, incorporating this simple step into your car routine can make a significant difference in preventing your car door from accidentally closing and ensuring your battery remains unaffected.

Prop the Door Open with a Wedge

Here’s how you can do it:

  • Find a small, sturdy wedge that fits securely under the door.
  • Ensure the wedge is placed at an angle that keeps the door from closing on its own.
  • Remember to remove the wedge when you’re ready to drive off to avoid any accidents.

Using a wedge is a convenient way to prevent your car door from shutting unexpectedly and maintain your battery’s charge. It’s a small but handy trick that can make a big difference in your daily routine.
