Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Turn off the engine and allow 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 carefully in
a counter -clockwise direction wh ile ap ­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system
or hot eng ine parts. Under certain condi­
t ions, the ethy lene g lycol in engine cool­
an t can ca tch f ire.
0 Note
Do not add any type of radiator leak seal­
ant to your vehicle's eng ine coolant. Add­
ing radiato r repair fluid may adve rsely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything i n the engine com­
pa rtmen t,
a lwa ys rea d and h eed all WARN ­
INGS c:::> A in Working in the engine compart ­
ment on page 257.
.. Tu rn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coo lant expansion
tank

c:::> page 264, Coolant.
.. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact spec ificat ions
c> page 264, Coolant.
We recommend using only coo lant additive
G12 ++, G13 or in an emergency G12 +. Do
not
use a different add itive. In an emergency use
plain water until you can get the correct addi­
t ive and can restore the correct ratio . This
shou ld be done as soon as poss ib le.
If you have lost a considerable amount of
coolant, then you should add cold ant ifreeze
and co ld water only when the eng ine is cold .
Always use
new engine coolant when refilling.
Do not fi ll coolant above the "MAX" mark. Ex­
cess coolant will be forc ed 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 it to coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, th ick rag.
- Turn the cap s low ly 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
cond it ions, the ethylene g lycol in en ­
gine coolant can catch fire .

s u re list e d on th e tir e s ide wall f or a ny r ea­
s on.
Remember that the vehicle manufacturer, not
the tire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the tires a re cold .
- Read the required t ire pres sure from the tire
pressure label. The ti re pressure label is lo­
cated on the driver's side 8-p illar . The t ire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on you r vehicle at the time it was man­
ufactured . For recommended tire pressures
for normal load condit ions, please see chap­
ter
c:> page 2 77.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the a ir pressure gauge on the valve.
- T he tire pressures should on ly be checked
and adjusted when the tires are cold. The
s li ghtly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I check the tire pressur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always befo re starting a journey. Do not
forget to check the tire pressure for the spare wheel.
When should I ad ju st th e tire p re ss ures?
Adj ust the tire p ressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then
store the new tire press ures in the tir e pres­
sure monito ring system
c:> page 293.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death .
- When the warn ing symbol
[I] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the hand ling of the vehicle and
stopping abi lity.
- I nco rrect tire pressures a nd/or underin­
f lation can a lso lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The drive r is responsible for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure mon itoring system can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re press ure monitor­
ing system.
- Always inflate t ires to the recommended
and correct t ire p ressure before dr iv ing
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread sepa ration, s udde n tire failure
and loss of cont ro l.
- E xcessive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. ..,

start to m ove whi le a whee l is being
changed.
- Never use the folding chocks if they are
damaged or i f they have not been assem­
bled correct ly.
A WARNING
Improper use of the vehicle jack can cause
ser ious personal injuries.
- Never use the jack supplied 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 .
- Us ing a bumper jack to raise the vehicle
will damage the bumper system. The
jack may slip, causing i njury.
- Never support your vehicle on cinder bloc ks, b ricks or other objects. Th ese
may not be able to support the load and
cou ld cause injury when they fail.
- Never start or run t he engine while the
vehicle is suppor ted by the jack.
- If you must wo rk under the vehicle, al­
ways use safety stand s spe cifically de­
signed for this purpose.
- Always make sure the inflatable spare
tir e a nd even a f lat t ire are se cured in
place and not loose, ot herwise they
cou ld fly forward, causing personal inj ury
to passengers in the veh icle in an acc i­
