C hanging the engine oil
The engine oil and o il fil te r must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls spe cified in your vehicle 's War­
ra nty
& Main ten ance booklet. Do not ex ceed
these in tervals - harmful depos its from ol d
engine o il can reduce engine performance an d
can lead to expensive engi ne re pairs.
C hanging the o il at th e recommen ded i nte r­
v al s is so very impor tant because t he lub ric at ­
ing p roperties o f oi l decrease gra dually du ring
norma l vehicle use . If you are not sure when
you have yo ur oil changed, ask yo ur aut ho r­
i z ed A udi Service Advisor.
Unde r some ci rc u ms tances the engine o il
should even be change d mo re frequently .
C hange o il more often if you drive mostly
short d istances, ope rate the vehicle in d usty
areas or mostly under stop-and-go traffic con­
d it ions, or when you use your veh icle w he re
tem peratures stay below freez ing poin t fo r
l ong periods .
Detergent addit ives i n the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a shor t time . This is no rma l and is not
a reason to change the o il mo re often tha n
r e co m men ded.
Damage or malfunctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine o il
that complies with Audi oi l standard
VW 502 00 (vehicles wi th gasoli ne e ngine) or
VW 507 00 (ve hicles with diese l engi ne) . Yo ur

Engine oil consumption
To prov ide effective l ubr ication and cooling for
i nter na l eng ine parts, a ll interna l combustion
engi nes use some o il. Oil consumption va ries
from eng ine to engi ne and may cha nge over
t h e life of the engine. Engines tend to use
more o il du ring t he b reak-in pe riod tha n they
do afterwa rd, w hen oil c onsum ption ha s sta­
b ilized. Dependi ng on the w ay the vehicle is
driven and the operati ng conditions, oil con ­
s u mption can be up to 1 q uart per 1, 200
miles (1 liter per 2,000 km) . Consumption
may be higher within the first 3,000 m iles
(5,000 km) .
Un der normal con ditions , the rate o f oi l con­
s u mption depen ds on o il quality as well as vis ­
cosity, engine spee d (rpm), outs ide tempera­
ture, road conditions, the amount of oil dil u­
t io n caused by condensed water or fue l resi ­
du e, and ox ida tion of the o il. Oil co nsu mp tion
may incr eas e with eng ine w ear ov er time, un ­
t il repl acemen t of w orn en gine p arts may be­
co me ne ce ssar y.
B eca use of all thes e var iables , there is no
sta nda rd o r "n orma l" ra te of o il cons umption .
We urge you to check the engine oil level at
regular intervals, preferably every time you
fill the fuel tank, and always before a long
trip.
The oil pressure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while driving (above 1500 rpm), a
buzzer will sound. It indicates that the oil
pressure is too low . Stop the engine immedi·
ately, check the engine oil level and add oil if
necessary. If the engine oil level is normal,
but the light continues to flash, do not keep
driving or let the engine idle, as damage may
occur .

284 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

F ig. 240 Rotat ing t ires for more ev en wea r
Tread Wear Indicator (TWI)
The o rigi na l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
.... N M
c::> fig . 239 running across the tread. Depend ­
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p res sure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 280.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Warranty
& Maintenance booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 240.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 302 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect wheel alig nment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop .
All-wheel driv e
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .
