Driving 71
- Never remove the ignition key from the
ignit ion lock while the vehicle is mov ing.
Otherwise the steering lock will engage
and you will not be able to steer the vehi­
cle.
- The brake booster and power steering
only work when the eng ine is running. If
the engine is off, you have to use more
force when stee ring or braking. Because
you cannot steer and bra ke as you usual­
ly would, this could lead to crashes and
serious inju ries .
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time . This applies partic­
ular ly when c hildren remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.

necessary. Because you cannot steer and
b rake as you usually would, this could
lead to accidents and serious injuries.
- The brake booster and power steering
only work when the engine is running . If
the engine is off, you have to use more

214 Checking and Filling
you have your oil changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods .
Detergent additives in the o il wi ll make fresh
oil look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended .
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00. Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to fa ilure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dea ler will have to
deny warranty coverage un less yo u present to
the dea ler proof in the form of Service or Re­
pair Orders that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports.
In order to provide effective lubrication and
cooling of internal engine components , a ll in­
ternal combustion eng ines consume a certain
amount of o il. Oil consumption var ies from
engine to engine and may change significantly
over the life of the eng ine . Typically, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
b reak-in period than they consume after oil
consumption has stabilized. Under
normal conditions, the rate o f oil con ­
s u mption depends on the quality and viscosity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
co nd ensat ion or fuel residue and the oxida­
t ion level of the oil. As any engine is subject to
wea r as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard ra te of oil consumpt io n can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the oil lev­
el , see
Note.
If the yellow engine oil leve l warning symbo l
Ill in the instr ument cl uster light s up, you
shou ld check the oil leve l as soon as possible
¢
page 215. Top off the oil at your earliest
convenience
~ page 215.
A WARNING
-~
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 210.
(D Note
Driving wit h an insufficient oil level is like­
l y to cause severe damage to the engine.
(D Tips
-The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­
erably each time you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some time. An authorized Audi ..,.

24 2 T ire s and wheel s
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory installed rims . If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 270.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
c ont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­ er ly t igh tened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue fo r th e wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i­
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque wheel bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -preferably by an author­
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ra tio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of d riving condi ­
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The n umera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pressure. It is therefore important that low
a spect ratio tires are inflat ed to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and always bef ore a long trip
r=> page 231, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amage d more
easily by impact w ith potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.
