232 Check ing and filling
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 225.
• Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the eng ine coolant leve l from the cool­
ant expansion tank
c> fig. 196, c> page 22 7,
fig. 193. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
ma rk ing.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢
page 22 7.
To obtain an accurate reading, the engine
must be sw itched
off.
The expans ion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System ¢ page l 6 will
i l luminate unti l yo u add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a lea k in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your author ized Audi dealer. It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
T he cooling system is unde r pr essure and
c an get ve ry hot. Reduce t he risk of s cald­
ing from hot coolant by followi ng these
steps .
- T urn
off the engine and allow it to cool
dow n. -
Protect your face, han ds and arms from
escaping flu id and steam by cover ing the
cap with a large, thick rag.
- Tu rn the cap slowly and very care fully in
a counte r-clockwise direct ion while ap­
plying lig ht, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine par ts. Under certa in cond i­
tions, th e ethylen e glyco l in engine coo l­
a nt can catch fire.
(D Note
Do not add a ny type o f radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator r epa ir fluid may adv erse ly af­
fe ct the funct io n and perfo rma nce of you r

We recommend using only coolant addi-
tive
Gl2++, Gl3 or in an emergency Gl2+. Do
not use a different additive. In an emergency
use plain water until you can get the correct
additive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifree ze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief 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
scalding from hot coolant by following
these steps.
-Turn off the engine and allow itto 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 carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an ­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank
is empty. Air could enter the cooling sys­
tem and damage the engine. If this is

the case, do not continue driving. Seek
professional assistance .
- Coolant pollutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure relief valve 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
c> page 231 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off.
It can even switch
on again later by itself
c> .&, if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

Before storing the jack, make sure it is wound
back down as far as it will go.
A WARNING
Im proper use of the vehicle jack can cause
serious personal injuries .
- Never use the screw driver hex head to
tighten w heel bolts, since the bolts can­
not attain the necessary tightening tor­
que if you use the hex head, potentially
causing an accident .
- The factory-supplied jack is intended on­
ly for your vehicle model. Under no cir­
cumstances should it be used to lift
heavy vehicles or other loads; yo u risk in­
juring yo urself.
- Never start the engine when the vehicle
is raised, which could cause an accident.
- Support the vehicle securely with appro­
pria te stands if wor k is to be performed
underneath the vehicle ; otherwise, there
is a potential risk for injury. ..,.

274 What do I do no w?
-Never use the jack s upplied with your
Audi on another vehicle, particularly on a heavier one. The jack is only suitable for
use on the vehicle it came w ith.
- Some of the on board items listed above
are provided on certain mode ls only or
are optiona l extras.

Using the spare tire (compact spare tire )
The compact spare tire is only intended for
emergenc ies until you can reach a repair shop.
Replace it as quickly as poss ible with a s tand­
a rd wheel and tire.
There are some restrictions on the use of the
compact spare t ire. Th e compact spare t ire
has been des igned specifically fo r your type of
ve hicle . It must not be swapped with a com­
pact spare ti re from another type of vehicle .
Snow chains
For technica l reasons, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow cha ins and a
front tire fails, mo unt the spare wheel w ith
tire instead of a rear t ire. I nstall the snow chains on the rear tire and use it to rep
lace
the defective front tire.
A WARNING
-- Never use the spare t ire if it is damaged
or if it is worn down to the tread wear in­
d icators.
- If the spare tire is more than 6 years old, use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­ porary and short-term use. It s hou ld be
replaced as soo n as poss ible with the
normal wheel and tire.
- After mounting t he compact spare tire,
the t ire pressure must be checked as
soon as possible . The tire pressure of the
compact spare t ire must be 4. 2 ba r; oth­
erwise, you risk having an a cc iden t.
- Do not dr ive faste r th an

- N ever d rive using more than one spa re
wheel and ti re. You r is k having an ac ci­
dent.
- Normal summer or winter t ires must not
be mounted on t he compa ct spare w heel

- For technica l reasons, the use of tire
ch ain s on the sp are tire is not permitted.
If i t is necessary to drive with tir e c hains,
the spare wheel must be mounted on the
f ront ax le in the event of a flat in a rear
tire. The new ly available front whee l
m ust then be insta lled in place of the
