Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
.. Wash the whee ls with a sponge or hose
brush every other week.
.. For deep cleaning afterwards, use only a
dedicated
aci d-fr ee cast alloy wheel cleaner.
.. Rub a coat of
liqui d wax onto the r ims every
three month . Be sure to reach and treat a ll
parts of the rim.
To preserve the decorat ive appearance of the
cast alloy wheels, some specia l care is neces­
sary. In addit ion to road d irt and sa lt , brake
dust is a lso cor ros ive.
If l eft on for too long,
brake dus t can cause pitting.
Use only specia l
acid-free cleaners formulated
for a lloy rims. Safe p roducts are available at
your author ized Audi dealer. Never leave the
cleane r on the rims longer than specified on
the label. If not rinsed
off promptly, the acid
contained in some cleaners can attack the
threads on the whee l bolts.
Never use ab ras ive or metal polishing clean­
ing agents. If the protective coating has been
chipped, e .g. by kicked up road dirt, touch it
up as soon as possible .
.&, WARNING
-Moisture and ice on brakes may affect
braking efficiency¢
page 188. Test the
brakes carefully each time you wash the
vehicle .
- Always read and heed all WARNINGS and
other information
¢ page 202.
Body cavity sealing
The body cavity sealing does not need to be
checked .
All body cav ities which could be affected by
corros ion have been thoroughly protected at
the factory .
This sealing does not require any inspection or additional treatment. If any wax should seep
out of the cavity when the ambient tempera­
ture is high, it can be removed with a plastic scraper and a suitable solvent .
.&, WARNING '"-'--
Solvents can be dangerous .
- Benz ine is flammable and toxic. If you
use benz ine for removing the wax, keep
spa rks, flame and lighted cigarettes
away. Never dump benz ine on the
g round, into open streams or down sew ­
age drains .
- Be s ure to observe all safety and environ­
mental regulations. Follow all instruc­
tions on the container.
- Always read and heed all WARNINGS and
other information ¢
page 202.
Chassis
Have the undercoating checked for damage
from time to time.
The lower body shell of your Aud i is also thor­
oughly p rotected against corros ion.
Any damage to the undercoat ing caused by
road hazards should be repaired promptly .
.&, WARNING
Too much undercoating in the wrong p la­
ces can cause a fire.
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, catalyti c con­
ver ter or heat shields. While driving, the
substance used for undercoating could
overheat and cause a fire.

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies wi th A udi oi l standard
VW 502 00 . Your Limited New Vehicle War ­
ranty does not cover damage or malfunctions
d ue to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
¢
page 194) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount 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 s ubje ct to
Checkin g and fillin g 223
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
1\1 in the instrument cluster lights up , you
sho uld check the oil leve l as soon as possib le
¢
page 224. Top off the oil at your earliest
convenience ¢
page 224.
A WARNING
Before you check anythi ng i n the engi ne
compartment, always read a nd heed all
WARNINGS¢ .&.
in Working in th e engine
c ompartment on page 219.
(D Note
D riving w ith an insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref­
erably ea ch time you refuel, and always
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes ex ce ss ive amoun ts of o il, we
recommend that you consul t an a uthor­
ized Aud i dea ler to have the cause of
your concern properly d iagnosed. Keep in
mind that the accurate measu rement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.

Gross Axle Weight Rating
The Gross Axle Weight Rating is the maximum
lo ad that can be applied at each axle of the
vehicle ¢Lr!, .
Vehicle capacity weight
The vehicle capac ity we ight (max. load) is list­
ed on the driver's side 8-p illar.
Roof weight
The maximum permissible roof weight is
198 lbs. (90 kg). The roof weight is made up
of the weight of the roof rack system and the
weight of the object be ing transported
¢ page 68, Loading the roof rack .
.&_ WARNING
- T he actual Gross Axle Weight Rating at
the front and rear axles should not ex­
ceed the permissible weights, and their
combination must not exceed the Gross
Vehicle Weight Rating .
- Exceeding permissib le weight ratings can
result in vehicle damage, accidents and
persona l injury.
(D Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transporting a heavy load in the luggage
compartment, carry the load as near to
the rear axle as possible so that the vehi­
cle's handling is not impaired .
- Do not exceed the maximum permissible
axle loads or the maximum gross vehicle
weight . Always remember that the vehi­
cle's handling will be affected by the ex­
tra load . Therefore, adjust your speed ac­
cordingly.
- Always observe loca l regu lations .
.
Dimensions
The specifications refer to the basic model.
Differences may occur depending on the mod­
el type and options ordered, for example, tire
sizes.
~ Note
When driving up steep ramps, on rough
roads, over curbs, etc. it is important to re­
member that some parts of your vehicle,
such as spo ilers or exhaust system compo­
nents, may be close to the ground . Be
careful not to damage them .

complexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, safe ty and e nvir onm en tal con­
cerns p lace very strict limits on the na ture of
repairs and adjustments to engine and trans ­
miss io n pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure prope r
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servici ng in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authorized Audi dealer or any other
properly equipped and q ualified workshop .
We strong ly urge you to give you r a uthorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and trained spec ialists to keep your vehicle
running properly .
Performing limit ed m aintenance you rself
The fo llowing pages describe a limited num­
ber of procedures which can be performed on
your vehicle with ordinary too ls, should the
need arise and trained personnel be unavaila­
b le. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and carefully follow the instruc­
tions given . Always rigorously obse rve the
