WARNING  
Engine coolant is poisonous!  
Always keep the coolant in its original container stored in a safe place.  
To reduce the risk of poisoning, never store engine coolant in empty food or beverage  
containers or in any other containers that might mislead someone into drinking from them.  
Always keep engine coolant out of reach of children.  
Always make sure there is enough of the correct coolant additive to provide proper  
antifreeze protection at the coldest temperatures that can be expected where the vehicle will  
be used.  
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.  
Coolant and coolant additives can pollute the environment. Collect leaking operating fluids and  
dispose of them properly in accordance with applicable environmental laws and regulations.
