188 Checking and filling
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure re lief valve in the cap when the en ­
g ine becomes hot.
A WARNING
- The coo ling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very ca refully
i n a co unte r-clockwise d irection while
apply ing light, downward press ure on
the top of the cap.
- To avoid being burned, do not spi ll an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can ca tch f ire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its original container and we ll
o ut of the reac h of children.
- If you drain the coolant, it must be
caught and safely stored in a p roper con­
ta iner clear ly ma rked "poison".
(D Note
- Do not add coolant if the expansion tan k
i s empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is
the case, do not continue driving. Seek
professional assistance.
- Coolant po llutes the e nv ironment and
could cause an engine fire. Excess coo l­
ant will be forced ou t through the pres ­
su re re lief v alve in the ca p when the en­
gine becomes hot .
- If, in an emergen cy, only water can be
added, the corre ct ratio be twee n wa te r
and antifr eeze¢
page 186 must be re ­
stored as soon as possib le .
{® For the sake of the environment
D rained coo lant should not be reused . A l­
ways d ispose of used coolant whi le observ­
i ng a ll environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
T he rad iator fan is driven by the engine v ia the
V-belt. The viscous clutch regulates the spee d
of the fan acco rding to the temperature of the
coolant.
An a uxiliary electric radiator fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing condit ions .
A ft er yo u sw itc h t he eng ine
off, the aux iliary
f an can continue running for up to 10 m inutes
- even wit h the ignition
off. It can even switc h
on again later by itself¢.&. , if
- t he tempe rature 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 i ntense sunlig ht.
A WARNING ~
- To reduce the risk of perso na l inj ury nev -
er touch the radiator fan.
- The a uxiliary electric fan is tempe rat ure
contro lled and can sw itch on sud denly
even when the engine is not running.
- The a uxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reac hes a certa in temperature and will
continue to ru n until the coolant temper­
ature drops.

192 Checking and filling
(D Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise, you will

214 Tire s and wheel s
When the malfunction indicator is illuminat­
ed, the system may not be able to det ect or
signal low t ire pressure as intended . TPMS
malfunct ions m ay occur for a variety of re a­
sons, including the installa tion 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.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monito ring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 157 Display : under inflatio 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 warning symbo l
RE and a
message¢
fig. 157 . If on ly one ti re is affect ­
ed, the location of that tire will be indicated .
The t ire p ressu re monito ring system must be
reset each t ime the press ures a re adjusted (e.
g . when switching between partia l and full
l oad pressure) or after changing or replacing a
tire on your vehicle ¢
page 215. The TPMS in­
dicator only monitors the tire p ressu re that
you have previously s tored. You can find the
recommended tire pressures for your vehicle
on the label on dr iver 's side B -pillar
¢ page 199.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- t he t ire press ure in one or more tires is too
low,
- t he t ire has s tructural damage ,
- the t ire p ressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset

-The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your authorized dealer if run-flat
tires may be used on your vehicle. Your
vehicle registration becomes invalid if
you use these tires when not permitted .
Damage to your vehicle or accidents
could also result.
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identification on the
tire sidewall

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increas ingly more and more
difficult to replace vehicle lig ht bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the bulb.
This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly taken apart and then properly put
back together to he lp prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
ly resealed.
For your safety, we recommend that you have
your authori zed Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights ):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light are identified by
the high voltage st icker.
A WARNING "--
Changing Xenon lamps without the neces-
sary equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening inju­
ries can result from improper handling of
the high-voltage portions of such lamps!
- Only your authorized Audi dealer or qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
@ Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine ..,.
