Yes, most hybrid vehicles can jump-start another car, but you must use the correct procedure to avoid damaging either vehicle's sensitive electrical systems. The key is to use the hybrid's 12-volt auxiliary battery, not its high-voltage traction battery. This smaller battery, which powers accessories like lights and the radio, is typically located in the trunk or under the hood and has standard jump-start terminals.
The process is similar to a conventional car jump-start but with critical precautions. First, ensure the hybrid is completely off, not just in "Accessory" mode. Connect the positive (red) jumper cable clamp to the dead battery's positive terminal. Connect the other red clamp to the hybrid's 12-volt battery positive terminal. Then, connect the negative (black) clamp to the hybrid's 12-volt battery negative terminal. For the final connection, attach the last black clamp to an unpainted metal surface on the dead car's engine block, away from the battery. This grounds the circuit and minimizes sparking risk. Start the working hybrid car, wait a moment, then attempt to start the disabled vehicle.
It's crucial to never attempt to jump-start another car using the hybrid's high-voltage components (usually marked with orange cables). This is extremely dangerous and can cause severe damage. The table below shows the 12V battery specifications for common hybrid models, which are suitable for providing a jump.
| Hybrid Model | 12V Battery Location | Typical Cold Cranking Amps (CCA) | Suitable for Jump-Starting? |
|---|---|---|---|
| Toyota Prius | Trunk | 300-400 CCA | Yes, with caution |
| Ford Escape Hybrid | Under Hood | 500-600 CCA | Yes, good capacity |
| Honda Accord Hybrid | Under Hood | 400-500 CCA | Yes, with caution |
| Hyundai Ioniq Hybrid | Under Hood | 450-550 CCA | Yes, good capacity |
| Lexus ES Hybrid | Trunk | 300-400 CCA | Yes, with caution |
Always consult your owner's manual first, as some manufacturers may have specific instructions or advise against it entirely. If you're unsure, calling for professional roadside assistance is the safest bet.

Absolutely, but you gotta be careful. My son did this for his buddy last winter. The trick is to find the small 12-volt battery in your hybrid—it’s not the big one that runs the electric motor. In my Toyota, it's in the trunk. Just hook up the cables to that battery like you normally would, making sure your car is totally turned off. It’s a simple boost, but you have to follow the steps exactly to avoid messing up all the fancy computers in these cars.

Technically, yes, it's possible because hybrids have a standard 12-volt battery for accessory power. However, the electrical systems in hybrids are more complex and sensitive than in traditional vehicles. An incorrect connection during a jump-start can lead to costly damage to the power control unit or other electronics. For this reason, I generally recommend using a portable jump starter pack or calling for professional help. It eliminates the risk of cross-vehicle damage.
