PREPARATIONS FOR TRIP  
Note: Any key made privately may not start the vehicle  
and may affect the safety of your car. To obtain a  
suitable key replacement, it is recommended that you  
consult an MG Authorised Repairer.  
Note: The new key cannot be offered to you  
immediately because it requires programming to the  
vehicle by the MG Authorised Repairer.  
Note: If your car is equipped with induction-type  
wireless charging function, always keep the key more  
than 20 cm away from the mobile phone which is  
being charged to prevent the key from the interference  
of the wireless charging device.  
Note: Avoid operating the smart key close to  
strong radio interference devices (such as notebook  
computers and other electronic products), as the  
normal function of the key may be affected.
