Warning! Do not allow antifreeze to come into contact with exposed areas of the body or painted surfaces of the vehicle. Wash away accidental splashes immediately with plenty of water. Remember that antifreeze is a highly toxic liquid and its ingestion, even in small quantities, can have the most serious consequences, including death. Never leave antifreeze stored in a loosely closed container; immediately collect any coolant spilled on the floor. Remember that the sweet smell of antifreeze can attract the attention of children and animals. Consult with local authorities about methods of disposal of used coolant - in many regions of the world, special collection points for various types of waste have been set up. Never pour old coolant into the sewer or onto the ground!
Caution! Drained coolant must not be reused. Coolant is toxic and must not be disposed of with household waste!
The coolant must be replaced every time repair work is performed that involves draining the cooling system, as well as work to replace engine components - during the circulation of the coolant, the anti-corrosion additives included in its composition are deposited on the surface of new parts, forming a protective layer that prevents the development of corrosion.
The procedure for replacing the coolant is described in Chapter Routine care and maintenance.
The coolant level switch is located at the bottom of the expansion tank on the right side of the engine compartment
