Engine 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
quires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-based coolant additive G13 antifreeze with
anticorrosion additives (50% for USA models;
60% for Canadian models). This mixture both
assures the necessary frost protection and
protects metal components in the engine's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water.
The
proportion of coolant additive must be at least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31°F(-35 °C)USA
- -40 °F ( - 40 °C) Canada.
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
¢ .&. in Working in the engine
compartment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in-
Checking and filling 223
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G12++ or G13 for your vehicle .
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully

a pply ing lig ht, downwa rd p ress ure on
the top of the cap.
- T o avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 223 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
T he radiator fan is driven by the engine via the
V-be lt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
Checkin g and fillin g 225
An auxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing con ditions.
After yo u switc h the engi ne off, the aux iliary
f an can con tinue r unning for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the heat b uild -up from the en gine in
the engi ne compartment, or
- the engine compartment heats up be cause
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can switch on sud denly
even when the engine is not running.
- The a uxiliary radiator fa n switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will

ment on page 216 . .,..

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 156.
Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod

Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again whe n you
turn on the ignition and sta rt the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
i s because more powe r is also consumed while
start ing , and the head lights, rea r window de­
fogger, etc., are used more often .

250 Tire s and wheel s
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or a lternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.

F ig. 181 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster w ith a
IE warning symbol and a
message¢
fig. 181 . The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
! SE T! button. If on ly one tire is affected,
the display will indicate its pos it ion.
The tire pressure monitoring system must be reset via radio or MMI * each time the pres­
sures are adjusted (e. g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢
page 251 . The TPMS indicator only moni­
tors the tire pressure that you have prev iously stored
. You can find the recommended tire
pressures for yo ur vehicle on the label on driv­
er's side B-pillar ¢
page 235.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire p ress ure in one or more tires is too
low,
- the t ire has structural damage ,
- the t ire pressure was changed, wheels rotat-
ed or rep laced but the TPMS was not reset

A WARNING
=
-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is sign ificant ly under­
inflated. Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In­
flate the tire pressu re to the prope r pres­
sure as indicated on the vehicle's tire
pressu re labe l¢
page 235. D riving on a
significantly under-inflated tire causes

the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for ma inta ining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed .
-Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle .
You r vehicle registrat ion becomes invalid
if you use these tires when not permit­
ted. Dam age to your veh icle or a cc iden ts
cou ld also resu lt.
@ Tips
- The t ire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The t ire pressure monitoring system on
you r Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall¢
page 242. We recom­
mend using these t ires .
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro ­
tated or changed, the TPMS must be reset via
radio or MMI* .
.,. Before resetting the TPMS, the current p res­
s u res of all four tires must correspond to
the specified val ues . Adjust the tire pressure
and reset the pressure in the tire press ure
monitoring system according to the load
you are carry ing
