~ Press and hold the rear window switch too
until the convertible top moves into the
service position¢
fig . 143 .
Opening the coolant e xpan sion tank cover
~ Stop the engine and allow it to cool.
~ Switch the ignition off.
~ Carefully remove the bolts in the cover (D
using a screwdriver and remove the cover.
The coolant reservoir is located below
¢fig. 144.
Chec king the engine cool ant level
~ Place a rag or cloth on the cap of the cool
ant expansion tank and turn the cap
careful
ly
to the left (counter-clockwise) ¢ .&_.
~ Read the coolant level inside the coolant ex
pans ion tank ¢
fig. 144 . With a co ld engine,
it must be above the "min" mark. With a hot
eng ine, it can be a little above the indicated
range.
T o obtain an accu rate reading, the engine
must be switched off.
The expansion ta nk in your vehicle is equ ipped
with an electric coo lant level sensor
¢page 15. We still recommend you check the
c oolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool
i ng system shou ld be inspected immediately
by your aut horized Audi dea ler. It is not
eno ugh me rely to add coolant.
In a
s ea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING ,~
- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan
sion tank when the engine is hot . You
risk being scalded .
- The coolant additive, and therefore the coolant itself, is hazardous to health.
Keep the coolant additive in the original
container out of the reach of children. It
is a poison hazard.
(D Note
Do not add any type of radiator leak seal
ant to your vehicle's engine coolant. Add
ing radiator repair fluid may adversely af
fect the function and performance of your cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ¢ &. in Working in the engine compart
ment on page 169.
.. Add coolant .
.. Twist the cap on again
tightly .
.. Tighten the cap (D ¢ page 176, fig . 144
again.
Replacement engine coolan t must conform to
exact specifications ¢
page 175, Coolant . If
the coolant additive G12+ + is not available in
an emergency, you must not add any other ad
ditive. In this case, use only water and restore
the correct mix ratio with the specified cool
ant additive as soon as possible.
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 .
With a major loss of coolant, you should add
the coolant only when the engine has
cooled.
In this way you prevent engine damage .
Checking and filling 177
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 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".
Q) Note
-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 ¢
page 175 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.

Checking tire pressure
The correct tire pressure for the tires original
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil lar.
The recommended t ire pressures are on the
tire pressure label and in the table
r:=> page 187, Cold tire inflation pressure . T his
means that the pressure must be checked and
a d ju sted when the tire has not been driven for
mo re than a couple of mi les (kilometers) at
l ow speeds during the p revious three hours.
Air in the tires expands when the tire heats up
as a result of internal fr iction as it flexes in
use. The tire pressure is higher when the tire
h as warmed up than when it is "cold".
It is the inflation pressure in a "cold" tire that
counts. Therefore, you shou ld never let air out
of a warm tire to match "Cold tire inflation pressure" recommendations
c> page 187. The
tires would then be under infla ted and could
fa il suddenly.
The tire pressure label on yo ur Audi lists t he
recommended cold t ire inflat io n pressures for
the new, or igina l equipment tires that were
on your vehicle at the t ime it was manufac
tured. For the location of the label
r=> page 187, fig. 148.
Most tires lose a ir natu rally over time. They
can also lose some a ir if you dr ive ove r a pot
h ole o r hit a curb while pa rking.
It is usua lly
n ot poss ib le to see whe ther the radial t ires
used today a re underi nflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east o nce a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long". See r:=>page 190, Tires and vehicle
load limits for more important information.
Always use an accurate tire pressure gauge
when check ing and adjusting inflation pres
sures . Check all of the t ires. If the pressure in
Tire s an d wheel s 189
any tire is too high when the tire is "cold", let
air out of the tire slowly with the edge of the
tire ga uge and keep checking the pressure un
ti l yo u reach the pressure that is correct for
the load (passengers and luggage) and kind of
driv ing you plan to do .
If the pressure in any ti re is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
t h e ve hicle load (passenge rs and luggage) for
the tires on your vehicle as l isted on the on
you r vehicle and in this ma nual a nd the k ind
of d riving you plan to do.
Never ex ceed the max imum inflation pres
sure listed on the tire sidewall for any rea
s on.
Remember that the vehicle manufacturer, not
t h e tire manu factu rer, determines t he correct
ti re p ressu re fo r th e tires on your ve hicl e.
It is important to check the t ire pressure when
the tires are co ld .
- Read the required tire pressure from the t ire
pressure labe l located on drive r's side B-pil
lar.
- T urn the va lve stem cap counter-clockw ise
to remove it from the tire va lve.
- Place the air pressure gauge on the valve.
- The tire pressures should o nly be checked
and ad justed when the tires are co ld . The
slightly raised pressures of warm tires must
not be reduced.
- Adj ust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the va lve.
When should I check the tire pr essu re?
T he co rrect ti re pressu re is especially impor
t a nt a t high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jo urney .
When should I adjust the tire pressures ?
Adjust the tire pressure to the load you a re
ca rrying. After chang ing a whee l
or replacing .,..
