pressure relie f valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- T urn off the engine and a llow it to cool
down.
- Protect your face, hands and arms from
escap ing flu id and steam by cover ing
the cap with a large, thick rag.
- Tu rn the cap slowly and very ca refully
in a counte r-clockw ise d irection while
applying light, downward p ress ure on
the top of the cap.
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
Q) Note
- Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant.
Adding rad iator repair fluid may adverse­
l y affect the function and performance of
you r cooling system and could result in
damage not covered by your New Vehicle Limited Wa rra nty.
- Coolant pollutes the env ironment and
could cause an engine fire. Excess coo l­
ant w ill be forced ou t through the pres­
su re re lief va lve in the cap when the en­
gine becomes hot .
- If, in an emergency, only water can be
added, t he cor rect ratio between wate r
and an tifreeze<=> page 201 must be re ­
stored as soon as possib le .

@) For the sake of the environment
Drained coolant sho uld not be reused. A l­
ways d ispose of used coolant while observ­
i ng a ll environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself .
T he radiator fan is dr iven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the coolant.
An a uxiliary electric radiator fan* switches on
and off depending on coolant temperature
and othe r vehicle ope rat ing cond it ions.
After yo u switch the eng ine off, the aux iliary
f an can continue running for up to 10 m inutes
- 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 build -up from the engine in
the engine compa rtment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
A WARNING
=
- To reduce the risk of personal inju ry nev-
er touch the radiator fan.
- The a uxiliary electric fan is tempe rat ure
contro lled and can switch on suddenly
even when the engine is not running.
- The a uxiliary radiator fan switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.

.,. Turn off the ignit io n and all electrical con­
s umer s .
.,. Make sure the area is well vent ilated when
you charge the bat tery .
.,. Open the engi ne hood
c::, page 195.
.,. Open the cover on the posit ive pole
¢ fig . 180 .
.,. Connect the charger connectors according to
the instructions to the
jump start bolts.
(Bolts under the cover= "positive", Bolts
with hex head = "negative").
.,. Only now plug the mains lead for the charg­
i ng equipment into the wall outlet a nd turn
it on
c::, &_ .
.,. Make sure the charging rate i s not over
30 amp s/14 .8 Volt .
Checkin g and fillin g 207
.,. When the battery is fully cha rged : T urn the
charging equ ipment off and
remove the
mains lead from the wa ll out let .
.,. Now remove the clamps for the charging
equ ipment.
.,. Close the cover on the positive pole .
.,. Close the hood
c::, page 195.
A d ischarged bat tery can freeze at tempera­
tures of only 32 °F (0 °C) . Allow a frozen bat­
tery to thaw completely before attempting to cha rge it
c::, .&. . However, we recommend not
u sing a thawed batte ry aga in because the bat­
tery casing can be cracked due to i ce fo rma­
tion an d can leak b attery a cid.
Battery charging (Maximum charging rate
of 30 amps /14.8 Volt )
When charg ing at low vo ltages (e.g. wi th a
t rickle charger ), the ba tte ry cables do no t
have to be disconne cte d firs t. T he bat tery
caps should
not be opened when charging a
batte ry .
It is no t necessa ry to remove the b attery from
the luggage compartment.
Fast charging the battery (charging rate
above 14 .8 Volts)
Fo r tec hni cal re asons do not use a bat tery
c h arger that uses voltage g reater than
1 4 .8
Volts to c harge yo ur veh icle's battery.
A WARNING
C harging a battery can be dangero us.
-A lways follow the operati ng instr uctions
provided by the battery charger manu ­
facturer when charging your battery .
- Never charge a fro zen battery. It may ex­
p lode because of gas trapped in the ice .
A llow a frozen battery to thaw out first.
- Do not reuse batteries wh ic h were fro­
zen. The battery housing may have
cracked and weakened w hen the battery
froze.
- Charge the battery in a well venti lated
area . Keep away from open flame or elec­
trical spark. Do not smoke . Hydrogen gas
generated by the battery is explos ive . ..,

p ressu re : Sys tem malfun ction !.
Ifffi:m appears after sw itching the ign ition on
or while driving and the indicator light
ti] in
the instrument cluster blinks for approxi­
mate ly one min ute and then stays on, there is
a system malfunction. Attempt to store the
correct t ire pressure
c::> page 241. If the ind i­
cator light does not turn off or if it turns on
shortly thereafter, immediately drive your ve­ h icle to an authorized Audi dealer or author­
i zed repair facility to have the malfunction
corrected.
_& WARNING
- If the t ire pressure indicator appea rs in
the instrument cl uster display, one or
more of you r tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures . In­
flate the tire pressure to the proper pres­ sure as indicated on the vehicle's t ire
pressure label
c::> page 217. Driving o n a
signific antly under-inflated tire ca uses
the tire to overhea t and can lead to tire
f ailure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures . You must
check the t ire pressures regular ly.
- 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 authorized Audi dealer if run­ flat tires may be used on your veh icle.

(D Tips
-The tire pressure monitor ing system may
stop working when there is an ESC ma l­
function.
- Using snow c hains may res ult in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
the "ROl" identificat ion on the tire side­
wall
c::> page 230. We recommend using
these tires.
Reset tire pressure monitoring system
App lies to vehicles : wit h tire p ress ure mo nitor ing system
If the tire pressure is adjusted, wheels ore ro­
tated or changed, the TPMS must be reset via
radio or MM!*.
.,. Before storing the new t ire pressures, check
that the current pressures on all four tires
correspond to the specified va lues and
adapt the pressures to the current load
