How to Jump Start a Car

mechanic using jumper cables to jump start car battery

With a basic understanding of essential car-care, you can address simple vehicle issues without stress. For example, knowing how to jump start a car is a fantastic skill to master in case you find yourself with a dead battery on Darien roads. Refer to this guide on how to properly jump start a car, and you’ll be able to get your engine fired right back up. 

How to Jump Start Car Battery

While you always have the option to call on jump start car service–like the one that comes with your Jaguar EliteCare–learning how to jump start a car yourself is quite rewarding and can save time! Once you’ve done it, you’ll be able to do it again or help a Greenwich neighbor. Here’s the proper way to jump start a car: 

  1. Find a friendly face with a working vehicle to help you. We’ll refer to this as the booster car. Park the hoods facing one another, or as close as possible. 
  2. Now, ensure both vehicles are off and engage both parking brakes. 
  3. Pop the hoods and locate both batteries. Remove any plastic housing as necessary. 
  4. Connect the red clamp to the positive terminal on the dead battery.
  5. Connect the red clamp to the positive terminal of the booster car. 
  6. Connect the black clamp to the negative terminal on the booster car.
  7. Connect the last black clamp to an unpainted metal surface on the dead car’s frame.
  8. Once everything is hooked up securely, start the booster car.
  9. Now, start the dead car. It should fire right up. If not, turn it back off, rev the engine on the booster car a few times, and try again. 
  10. Once the jumped engine turns over, remove the cables in the opposite order you clamped them. Be careful to keep them from touching each other, as this can create dangerous sparks.
  11. Drive the jumped car for a while throughout New Canaan or elsewhere as this will allow your car to regain an ample charge. 

If you shut your vehicle off too quickly, it may not retain the charge. You’ll need to give your alternator time to work! If your car won’t jump start, it’s likely that you’re in need of a new battery. If you’re in the Darien area, you can pick up a suitable replacement at our parts department.
