Yes, you can jump-start a hybrid car, but the process requires specific precautions to avoid damaging its complex electrical system. The key is to connect the jumper cables to the 12-volt auxiliary battery, not the high-voltage traction battery that powers the electric motor. This 12-volt battery, often located in the trunk or under the hood, is responsible for starting the car's computer and accessories. Connecting cables directly to the high-voltage system is extremely dangerous.
The correct steps are crucial for safety. First, consult your owner's manual for the exact location of the 12-volt battery terminals. With both cars off, connect the positive (red) clamp to the dead battery's positive terminal, then the other positive clamp to the booster car's good battery. Next, connect the negative (black) clamp to the booster car's negative terminal, and attach the final negative clamp to an unpainted metal surface on the disabled hybrid's engine block, not the battery. Start the booster car, then attempt to start the hybrid. Once running, disconnect the cables in the reverse order.
Many modern hybrids have a specific jump-start terminal under the hood to make this process safer and easier. If you are unsure or uncomfortable, calling for professional roadside assistance is the safest choice to prevent costly damage to the vehicle's sensitive electronics.
