In order to ensure maximum performance of the traction battery cooling system and limit

risks of battery short-circuit and other damage to your vehicle, Lexus recommends using

“Toyota Genuine Traction Battery Coolant” or similar high-quality ethylene glycol-based,

low electric conductivity coolant, non-amine and non-borate coolant with azole addi-

tives.

Lexus cannot guarantee that the use of a product other than “Toyota Genuine Traction

Battery Coolant” will prevent risks of battery short circuit or other damage.

Never use water as it will cause damage.
