Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory. This coolant must not be not changed.
The coolant leve l is monitored through the. in­
d icator light~
page 26. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents. Only use the fo llow­
ing coolant add it ives. These additives may be
mixed w ith each other.

The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the eng ine.

- Befo re the start of winter, have an author­
i zed Audi dealer or authorized A udi Se rvice
Fac ility check if the coolant additive in your
328
vehicle matches the per cen tage appropriate
for the climate . This is especially important
when driving in colder climates.
- If the appro priate coo la nt additive is not
availab le in an eme rgency, do not add any
ot her additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant add itive as soo n as poss i­
ble.
- Only ref ill w ith new coolant.
- Radiator sealant must not be mixed with
the coolant.
Adding coolant

Checking the engine coolant level
.. Park the vehicle on a level sur face .
.,. Switch the ignit io n off.
.,. Read the coolant level on the coolant expansion
tank
~ fig. 269.
.,. Th e coolan t level must be between the MIN and
MAX marki ngs when the engine in co ld. When
the engi ne is warm it can be sligh tly above the
MAX marking .
Adding coolant
Requirement: there must be a residua l amount of
coolan t in the expansion t ank

:E .. Push the release button ¢ fig. 269 and careful­
ly unscrew the cap to the left until you feel re­
sistance ¢,&. .
.. Push the release button again and remove the
cap completely .
.. Add coolant mixed in the correct ratio
¢page 328 up to the MAX marking .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.

an accident. Do not continue dr iving. See an
authorized Audi dealer or authorized Audi
Serv ice Facility for assistance.
- If the brake fluid is old, bubbles may form
in the brake system dur ing heavy braking.
This would impair braking performance and
driving safety, which increases the risk of an
accident.
- To ensure the brake system functions cor­
rectly, only use brake fluids that comp ly
with VW standard 501 14 or FMVSS-116 DOT 4.

perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
