Checking engine coolant level
When the engine is cold, check the engine coolant level relative to
the marking on the side of the expansion tank ⇒ fig. 168.
If the coolant level in the tank is below the minimum mark (“min”),
add coolant. When the engine is warm, the engine coolant level may
be slightly above the upper edge of the marked range.
Adding engine coolant
Always protect face, hands and arms from hot escaping coolant or
steam by covering the cap with a large, thick rag.
Carefully unscrew the cap ⇒ .
Add only new engine coolant according to Volkswagen specifica-
tions (⇒ Engine coolant specifications) ⇒ .
The engine coolant level must be inside the marks on the side of
the reservoir ⇒ fig. 168. Do not fill above the top edge of the filling
range! ⇒ 
Screw the lid tightly.
Even in an emergency, do not use any other kind of coolant addi-
tive if engine coolant meeting Volkswagen specifications (⇒ page 456,
Engine coolant specifications) is unavailable! Instead, add distilled
water only ⇒ . As soon as possible, have the correct coolant ratio
restored using engine coolant that meets Volkswagen specifications
⇒  Engine coolant specifications.
