Checking

1

Check antifreeze content in low temperature circuit for power electronics (1)

 Antifreeze content must be at least

-37 °C.

Antifreeze content less than -37 °C, continue with operation step 2.

Antifreeze content as from -37 °C, continue with test step 3.

2

Extract coolant from low temperature circuit for power electronics (1)

 Extract 0.35 l coolant and top up with pure antifreeze protection.

Use one container of antifreeze protection for two vehicles.

3

Check antifreeze content in low temperature circuit for high-voltage-battery (2)

 The expansion reservoir is located in the trunk under the left covering. Antifreeze content must be at least

-37 °C.

Antifreeze content less than -37 °C, continue with operation step 4.

Antifreeze content as from -37 °C, end measure.

4

Extract coolant from low temperature circuit for high-voltage battery (2)

 Extract 0.55 l coolant and top up with pure antifreeze protection.

Use one container of antifreeze protection for two vehicles.

5

Vent low temperature circuit for high-voltage battery (2)

 Only when coolant was extracted from low temperature circuit for high-voltage battery (2).
