Yes, you can jump-start a car with a push-button start, but the process has a critical extra step compared to a traditional keyed ignition. The most important thing to remember is that you must place the key fob directly against the start/stop button during the final step. This is because the car's security system needs to verify the key is present, and a dead car battery can weaken the fob's signal.
The jump-starting procedure itself is standard. You'll need a set of jumper cables and a running vehicle with a good battery. Park the cars close but not touching, turn both off, and engage the parking brakes.
- Connect the Cables: Attach the red (+) clamp to the dead battery's positive terminal. Connect the other red clamp to the good battery's positive terminal. Then, attach the black (-) clamp to the good battery's negative terminal. For the final black clamp, connect it to an unpainted metal surface on the dead car's engine block, like a bolt. This provides a ground and is safer than connecting directly to the negative terminal, which can reduce the risk of sparking near battery gases.
- Start the Donor Car: Let the donor car run for a few minutes to charge the dead battery.
- The Key Step for Push-Button Start: Take your key fob and physically press it against the start/stop button. This ensures the car can read the fob's chip. While holding it there, press the brake pedal and then press the start button. The car should attempt to start.
If it starts, carefully disconnect the cables in the reverse order. Let your car run for at least 15-20 minutes to allow the alternator to recharge the battery. If it doesn't start after a couple of tries, the battery may be too old or there could be a more significant electrical issue requiring a professional mechanic.
