Cooling
system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro-
tects the engine from freezing in the winter.
The cooling system is sealed and generally re-
qu ires little attention .
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of a mixture of
specially conditioned water and the manufactur-
er's g lycol-basedcoo lant additive G13 antifreeze
with anticorrosion addi ti ves (50% for USA mod-
e ls· 60% for Canadian mode ls). This m ixt ure
'
both ass ures the ne cess ar y fros t protection and
protects metal com ponents in the engi ne's coo l-
ing system from corrosion and scaling . It also
raises the boiling point of the coolant.
Do not red uce the concent rat ion of t he cool ant in
the summer by addi ng pla in water. The propor-
tion of coolant additive must be at lea st 50 %
but not more than 60 % to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coo lant could
freeze and damage the vehicle heat ing and en-
g ine cooling system .
For year -round driving, antifreeze is added at the
factory for temperatures
down to:
- - 3 1 °F

If you must add coolant, use a m ixt ure of wa t er
and coolant add it ive. Mixing the coolant additive
with d istilled water is recommen ded.

Note
- Before w inter sets in, have the coolan t
checked to see if the coo lant additive in your
vehicle is suff icient to meet the climate con-
ditions. This is especially important if you
live in a region where the winter is extreme-
ly cold. If necessary, increase the proportion
of coolant addi t ive to 60% .
- Whe n adding coolant additive to your cool-
ing system, remember:
- We re commend us ing on ly coo lant addi-
tive G12++ or G13 f or your vehicle. This
coolant ad d it ive is availab le at authorized
Audi dealers. Other types of antifreeze can
significantly reduce corrosion protection.
The resulting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of radiato r leak sealant
to your vehicle's engine coolant. Adding ra-
diator repair fluid may adversely affect the
function and perfo rmance of yo ur cooling
system and cou ld resu lt in damage not cov-
ered by your New Vehicle Limited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
