164 Cleaning and protection
regular basis, fo r example when
refuelling your vehicle.
- Never use a dry cloth or sponge to clean
the headlights . Only use wet cloths or
sponges to prevent scratches. It is best
to use soapy water.
@J For the sake of the environment
In the interest of the env ironment, the ve ­
hicle sho uld only be washed in special
wash bays.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you observe a few simple rules .
.. Before us ing the power washer, make sure
you have read and understood the WARN­ INGS
c> & in General information on
page 162.
.. Always fo llow the operating instructions for
the power washer .
.. Make sure that the jet on the spray hose pro ­
duces a "fan shaped spray".
.. Do
not hold the spray nozzle too close to
soft materia ls.
N eve r u se a pow er w asher to clean the power
top itse lf.
When clea ning t he vehicle w it h a powe r wash­
e r
always fo llow the operating instructions.
This applies particularly to the
o pera tin g
p re ssu re
and the s p ra yi ng dist ance. Maintain
a sufficient distance to soft materials such as
rubber hoses and so und/vibration deadening
materia ls (part icularly on the underside of the
engine hood). Do not use a jet wh ich sprays
water in a
dire ct st ream or one that has a ro ­
tat ing
jet .
Water temperature shou ld not exceed 140 °F
(60
°() .
A WARNING
Never wash tires w ith a jet that sprays wa ­
ter in a d irect stream. This could cause in- visible damage to the tires and weaken
them, even
if the spray is from a relative ly
long distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal inju ry.
(D Note
- Never use a power washer to clean the
power top itself.
- To avoid damaging your veh icle, always
make sure that there is sufficient dis­
tance between the spray head and soft
materials like rubber hoses, plast ic parts
and sound-deadening materials. Never
aim the spray head at the same point for
a long time. This also app lies to cleaning
head lights and pa inted b umpe rs. Re­
member: the closer the nozz le is to the
surface of the material, the greate r the
stress on the materia l.
Convertible top care
The convertible top requires special care.
Keeping you r top looking great and mak ing
certain tha t it lasts a long time depend to a
great extent on proper use and care . Remove
bird droppings as soon as possible, since the
corrosive chemicals in them will cause the
rubber impregnation in your top to swell and
poss ibly allow the fabric to leak .
With
normal soiling, all you need to do is
clea r the top with a soft br ush and clear wa­
ter. A lways brush in the direction of the fabric
from front to rear.
If the top is very dirty and has spotted areas
clean it with a brush using a convertible top
cleaner . Always brush in the direction of the
fabric from front to rear. R inse with plenty of
clear water, and allow the top to air-dry.
Chamois are not suitable for drying the top.
Never use gaso line, spot remover, benzene,
paint thinner or solvents to remove spots . We
recommend that you on ly use cleaners espe­
cia lly formulated for use on convertib le tops,
and that you fo llow the produce use directions ...

182 Checking and filling
Deterge nt additives in the o il wi ll 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. Yo ur Limited New Veh icle 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& Maintenance 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 period (see
c::;, page 157) 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 s ubject 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
m lights up, yo u
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 183. Top off the
o il at your earliest conve nience
c::;, page 183 .
A WARNING
-Before you chec k anything in the engine
compartment, a lways read and heed a ll
WAR NIN GS
c::;, .& in Working in the engine
comportment on page 178.
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
re ly on it . Instead, check the oil level in
your engine at r egular interval s, pr ef­
erably e ach time you refu el, and always
before going on a long trip.
- If you have the impressio n yo ur engine
cons umes ex cessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control,
but can also damage important pa rts of the
vehicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
l oad limits are technically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coo lant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a designated seat ing pos ition
and the total weight of any l uggage in the ve­
h icle.
The
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stick er labe l located on the
driver 's side 8-p illar. Your Audi has 2 seat ing
positions. Each seating pos ition has a safety
be lt ¢
page 107, Safety belts.
The fact that the re is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle is limited. The more passen­
gers in the vehicle or passengers who are heavier
than the standard weights assumed
mean that less weight can be carried as lug­
gage.
T he tire pressure label on your Audi also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label ¢
page 198, fig. 146.
A WARNING
Overloading a vehicle can cause loss of ve­
h icle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ithin a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and 5udden deflation, cau5ing lo55 of
control and a crash.
Determining correct load limit
Use the example below to cal­
culate the total weight of the passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF QC­
CU PANTS AND CARGO
SHOULD NEVER EXCEED XXX .,..

212 Tires and wheels
Tire pressure
monitoring system
General notes
Appl ies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
f lated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has t ires of a different size than the
size indicated on the vehicle placard or tire in­
flation pressure label, you should determine
the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­
er's responsib ility to ma inta in correct tire
pressure , even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not operating properly. The
TPMS malfunction indicato r is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
f lash for approximately one minute and then
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists. When the
malfunction indicator is illuminat­
ed, the system may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ens ure that the re­
placement or alternate ti res and wheels allow
the TPMS to continue to function properly.

Run-flat tires
Introduction
Applies to vehicles: with Run-flat tires
Run-flat tires help keep you moving if a tire
goes flat.
Reinforced s idewalls give the tires run-flat ca­
pability if tire pressure is lost.
We recommend that run-flat tires only be
mounted on vehicles that were originally
equ ipped w ith these special tires at the facto­
ry and have a Tire Pressure Monitor ing Sys­
tem.
Run-flat t ires can be ident ifi ed by th e lett ers
"RSC" on the tire sidewall.
If you do change the tires on yo ur vehicle from
normal to run-flat tires, you must buy the
specia l rims required for run-flat tires, and the
Ti re Pressure Monito ring System must be re­
programmed by an a uthorized Audi dea ler or
other qualified workshop.
What do run-flat tires do?
These special tires have run-flat capabilities
that help keep you moving if a tire loses pres­
sure and goes flat. Under favorable cond itions
tires can be driven
at l ea st 30 mil es (SO km ),
but you must not d rive fa ste r than SO mph
(80 km /h)

When it is not po ssible to continue
driv ing , ev en with run-flat tire s?
- If the Electronic Stabilization Program (ESP)
is not work ing or keeps coming on.

from a damaged tire as the wheel turns, and
hit parts of the vehicle, such as the fuel tank
filler neck, fuel lines or brake lines.

occurs or if the t ire starts to smoke because
the tire is ru nning hot.

tire, such as cracks in the sidewall, appears.
