Fig. 154 Engine coolant temperature gauge in the instrument cluster: A Engine cold; B Normal temperature range; C Warning zone.

x Carefully unscrew the cap ⇒ .
x Add only new engine coolant according to Volkswagen specifications (⇒ Engine coolant
specifications) ⇒ .
x The engine coolant level must be inside the marks on the side of the reservoir ⇒ fig. 155. Do not
fill above the top edge of the filling range! ⇒ 
x Screw the lid tightly.
x Even in an emergency, do not use any other kind of coolant additive if engine coolant meeting
Volkswagen specifications (⇒ 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.
WARNING
Hot steam and hot engine coolant can cause serious burns.
x Never open the hood if you see steam or coolant escaping from the engine compartment. Always wait until you no longer see or hear steam or coolant escaping from the engine.
x Always let the engine cool down completely before carefully opening the hood. Hot components will burn skin on contact.
x When the engine has cooled down and you are ready to open the hood:
– Firmly apply the parking brake and shift the transmission into Park (P) (automatic) or Neutral (manual only).
– Take the vehicle key out of the ignition.
– On vehicles with Keyless Access, make sure that the remote control vehicle key is out of range of the vehicle and that the vehicle cannot be started by depressing the starter
button ⇒  Starter button.
