Brake Fluid - Audi TT Roadster 2016 Owner's Manual

Checking and topping up fluids
Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A
WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children - risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!
CD
CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system - risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.
