celerating and heavy engine loads .
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on . If the . indicator light in the Infotain­
ment system display turns on, the coolant tem­
perature is too high

Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant level is monitored through the. in­
dicator light
¢page 12. However , we do recom­
mend occasionally check ing the coo lant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freez ing and
corros ion protection agents. Only use the follow­
ing coolant addit ives . These additives may be
mixed with each other.
Coolant additive Specification
G13 TL 774
J
G12++ TL 774 G
The amount of coo lant add itive 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 engine.
Coolant addi- Freeze protec-
tive tion
Warm regions min. 40%, m in. -13 °F
max. 45% (-25 °C)
Cold regions min. 50%, max

max. 55% (-40 °C)
(D Note
- Before the start of winter, have your author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate . Th is is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other 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 it ive as soon as possi­
ble.
- Only refill with new coolant .
- Radiator sealant must not be mixed with
the coolant.

Checking and Filling
Audi dealer or authorized Audi 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 pressurized and can be­
come very hot. To reduce the r isk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure o n the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­ haust system or hot eng ine components .
T he ethylene glycol in eng ine coolant can
catch fire under certa in circumstances.
- The coo lant add itive and the coolant can be
dange rous to your health. For this reason,
keep the coolan t in the origina l container
and away from children. There is a risk of
poisoning.
- When working in the engine compartmen t,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of inj ury.
(D Note
Do not add coolant if the exp ansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.

Consumer information
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can
perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty.
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for
upholding a possible warranty claim made within
the warranty period.
Above all, operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passenger.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly
equ ipped and qualified workshop. We strongly
urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­
nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly.
Performing limited maintenance yourself
The following pages describe a limited number of procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­
ly follow the instructions given. Always rigorously
observe the
WARNINGS provided.
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
