- Move the two vehicles closer to connect the cables. However, the two cars must not be close together (absence of contact) to avoid any risk of electrical short circuit.
- Before attempting to start, turn off the car’s engine. Also turn off the ignition, lights and other accessories. Finally, make sure that both parking brakes are firmly applied. Remember to wear protective glasses!
