(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the oil level in your engine at regular inter­
vals, preferably each time you refuel, and always before going on a long trip .

Braking
General information
What affects braking efficiency?
Operating conditions and d riving habit s
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat­
i ng cond itions and dr iv ing habits
c:> & . On
ve hicles that a re e ithe r dr iven mostly in stop­
and-go city traffic o r a re driven ha rd , the
b rake pads should be checked by yo ur auth or­
iz ed A udi dealer more often th an specifie d in
the
Warranty & Maintenance booklet . Fail ure
to have your b ra ke pads inspected can res ult
in red uced b rake performance.
O n steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the engine . This way, yo u preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously . P u mp the brakes at inter­
va ls.
N oises may occur w hen braking depending on
the speed, bra king force and outside condi ­
tions s uch as temperature and h umidity.
Moisture or road salt
Unde r cert a in co ndi tions, for examp le, w hen
d riving through wate r or ve ry heavy rain , or
even after washing yo ur vehicle , the braking effect can be
reduced due to mois ture (or in
freez ing cond itions ice) on the brake pads. A
f ew cautio us brake applications s hou ld dry off
the brake pads or remove any ice coatings.
T he effec tiveness of the brakes can be red uce d
whe n the vehicle is d riven on a sa lt -covered
road and the b rakes are not used . Likewise,
yo u clean off acc umulated salt coat ing from
brake d iscs and pads with a few cautio us ap­
plicat ions o f th e b rake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
t h e d iscs if the car is not driven regu larly or
o n ly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads a nd d iscs by braking
firmly a few times from a moderately h igh
s p eed
c:> & .
Faults in the brake system
If you shou ld notice a sudden increase i n
brake pedal trave l, then one of the two brake
c ircuits may have fa iled

Low brake fluid level
Malfunctions ca n occ ur in the bra ke system if
t h e b rake fluid level is too low. The brake flu id
level is monitored electronica lly.

& WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp meta l components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter . The
brakes must be dried first with a few
careful brake applicat ions .
{[) Note
-If you wash the vehicle in an automatic
car wash, you must retract the extend a­ ble rear spo iler* if necessary, and fold
the exte rior m irrors in to reduce the risk
of damage. Power folding exterior mir­ rors* must only be folded in and out us­
i ng the power folding function .
- To prevent pa int damage, do not wash
the veh icle in direct sunlight.
- To reduce the risk of damage, do not
wash the power top with a p ressure
washer. -
To reduce the r isk of damage, do not
wash decorative decals * with a pressure
washer.
- To reduce the risk of damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or hard wax.
- Never use car wash cycles that apply
protective wax.
It can destroy the
matte fi nish effect.
- Do not place any stickers o r magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
are removed.
@ For the sake of the environment
Only wash the vehicle in facilities spec ia lly
designed for that purpose. This will reduce
the risk o f dirty water contaminated with
oil from entering t he sewer system.

168 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::> page 149) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
1\1 lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::> page 169. Top off the
o il at your earliest conven ience
c::> page 169 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS
c::> .& in Working in the engine
comportment on page 164.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil level in
your engine at r egular intervals, pr ef­
erably ea ch time you refuel, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dea ler to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requires great care and may
take some t ime . Your Audi dea ler has in­
st ruct ions about how to measure oil con­
sumption acc urately.

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins 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 of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D 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). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
