contact with engine oil.
(D Note
-The engine o il level must not be under the
" min" marking, because this incre ases the
risk of engine damage.
-If the message II Pl ea se redu ce oil lev el
appears, there is too much oil in the eng ine
and there is a risk of damaging the cata lytic
converter and engine. Do not start the en­
gine . Contact an authorized A udi dealer or
authorized Audi Service Fac ility to have ex­
cess engine o il extracted if necessary .

@ For the sa ke of the env ironment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
- The oil level indicator in the display is only
an informational disp lay. If the oil leve l is
too low, a minimum oil warning appears in
the instrument cluster. Add oil and close
the hood. The current oil level is displayed in the instrument cluster the next time the
ignition is switched on .
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depend ing o n driving style and operating
cond itions. Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
ca use of th is, the engine oil level m ust be
checked regularly.
It would be best to check
each time you ref uel your vehicle and before
l ong drives.
Changing the engine oil
We recommend that hove your oil changed by an
authorized Audi dealer or a qualified service sta­ tion .
Before you check anyth ing in the engine compart­
ment,
al ways r ead and h eed all WARNIN GS~ &
in Working in the engine compartment on
page 330.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if yo u drive mostly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Check ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem of proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi de aler or
a qual ified service stat ion.
If yo u choo se to ch ange your oil yo urself , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .

Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory . T his coolant must not be not changed.
The coolant leve l is monitored through
the . in­
d icator
light ~ page 30. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant , use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents . Only use the fo llow­
ing coolant add it ives . These additives may be
mixed w ith each other.

Observe the safety precautions ~ A in Working
in the engine comportment on page 330.
Checking the engine coolant level
.,. Park the vehicle on a level surface .
.,. Switch the ignit io n off.
.,. Read the coolant level on the coolant expansion
tank
¢ fig. 278 .
.,. The coolant leve l must be between the MIN and
MAX markings when the engine in cold. When
the engine is warm it can be slightly above the MAX marking .
Adding coolant
.,. Let the engine cool down.

.. Place a cloth over the coolant expansion tank
cap .
.. Push the release button ¢ fig. 2 78 and careful­
ly unscrew the cap to the left until you feel re­
sistance¢ &_ .
.. Push the release button again and remove the
cap completely .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Serv ice Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
-The coolant additive and the coolant can be
dangerous to your health . For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
-When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air i n the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dea ler or author­
ized Aud i Service Facility for assistance.

Wheels
Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
