Do not mix G 13 with G 12 plus or G 11. Mixing these coolant additives together significantly reduces
corrosion protection ⇒ and can lead to electric motor damage that is not covered by any Volkswagen Limited Warranty.
WARNING
Too little antifreeze protection in the electric motor cooling system can cause electric motor failure and severe injuries.
x Always make sure there is enough of the correct coolant additive to provide proper anti-freeze protection at the coldest temperatures that can be expected where the vehicle will be used.
x At extremely cold temperatures, the coolant could freeze, causing the vehicle to break down. The heater would also not work, and vehicle occupants could be without protection at subfreezing temperatures.
NOTICE
Never mix original Volkswagen electric motor coolant additives with other additives not ap-proved by Volkswagen. Mixing Volkswagen coolant additives with coolant additives made by other manufacturers can seriously damage the electric motor and the electric motor cooling system.
x If the fluid in the electric motor coolant reservoir is any color but pink, then G 13 was mixed with a different electric motor coolant. If this is the case, the electric motor coolant must be replaced immediately. Otherwise serious malfunctions or electric motor damage can occur!
Electric motor coolant and electric motor coolant additives can pollute the environment. Collect leaking operating fluids and dispose of them properly in accordance with applicable environmental laws and regulations.
