Refer to your owner’s manual for important safety information regarding vehicle charging.
When using public charging stations, a good practice is to:
Always check the charging station’s charging receptacle for signs of excessive wear or debris within the charge handle ports as this could indicate a potential shock hazard. Note that a public charging station is in constant use and exposed to the elements, and wear over time can be an issue. If after you have visually checked the charge port receptacle and it appears that the ports are damaged or debris filled, do not use the charging station, and move to another charge station to charge your vehicle’s battery. Additionally, do NOT touch the charge ports or use any tool to attempt to remove debris from the charge handle ports as potential electrical shock can occur.
b.    Never use an EV charger with obvious signs of damage.
c.    Finally, ensure that the charging station receptacle fastens snugly into your car’s charging port, a worn receptacle may prevent a secure and safe connection to your vehicle.
