@ For the sa ke of the env ironment
- Engine oi l should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
The engine oil consumption may be up to 0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this,
the engine oil level must be checked regular­ ly.
It would be best to check each time you re­
fue l your vehicle and before long dr ives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays r ea d and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 244.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
n ance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d ur ing normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if you d rive mostly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop-and -go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook da rk after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of p roper disposal, along
with the special tools and necessa ry expertise re­
qu ired, we strong ly recommend that you have
Ch eck ing and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If yo u choo se to ch ange yo ur oil your self, please
note the follow ing important info rmation:
A WARNING
=
To reduce the risk of persona l injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protect ion .
-
-To redu ce the r is k of burns from hot eng ine
oil, let the engine cool down to the touch.
- W hen remov ing the oil d rain plug w ith your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in yo ur engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water.
(D Note

These additives can damage your engine and
adverse ly affect yo ur Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before chang ing yo ur oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .

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 pressurized and can be­
come very hot . To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth .
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap .
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components .
The ethylene g lycol in engine coolant can
catch fire under certain circumstances.
- The coolant add itive 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 sw itch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.

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.
.,.M ark 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.
