A WARNING ,~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv­ ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM in order
to raise the engine oil temperature to a mini­ mum of 140 °F (60 °C) . The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can continue to run in your ve­ h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important . Du ring sporty driving, the
engine and brakes, the exha ust system, and
the transm ission all become ext remely hot.
Before you park the vehicle, you shou ld drive
Dri vin g and en vironm ent 185
it for a few miles/kilometers at light load in
the low rpm range to allow it to cool down.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
"" Always use lead-free gasoline c> page 202,
Fuel supply.
"" Never run the tank down all the way to emp­
ty.
"" Never put too much motor o il in your engine
<=> page 212, ~ Adding engine oil .
""Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
up" device bui lt into the exhaust system of
the ve hicl e. The cata lytic conve rter bu rns
many of t he pollutants in the exha ust gas be­
fo re t hey are re leased into the atmosphere.
The exclusive use of unleaded fue l is critically
important for the life of the catalyt ic convert­
er and proper funct ion ing of the engine.
A WARNING ~
- The temperature of the exhaust system
is high, both when driving and after stop ­
ping the engine.
- Never touch the exhaust tail pipes once they have become hot . This could result
in burns .
- Do not park or operate the vehicle in areas where the hot exha ust system may
come in contact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substanc e used fo r undercoating could
overheat and cause a fire. •
•

186 Driving and en vironm ent
-Be aware that just one tank fi lling with
le a ded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
qpage 212.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire. Unburned fuel could also get into
the exhaust system and this could cause
t h e catalyt ic converte r to overheat.
- Do not turn off the ignition while the ve­
hicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherw ise fuel
can reach the catalytic converter. This
could result in overheat ing of the co n­
ve rter, req uiring its repla ceme nt.
- To assure efficient operation of the Emis­
s ion Control System:
- Have your veh icle maintained properly
and in accordance with the service rec ­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack o f proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Control System is
operati ng properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating sta tes. This depends on
t he s ulfur content of the fue l being used .
Using a differe nt brand of fuel may help,
or filling the t ank w it h lead-free super
grade gaso line .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels.
F uel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving s tyle
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRON MENTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
s pon d to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
.,. Avoid unnecessary accelerating and brak ing.
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
au thorized Aud i dea ler helps to ensure that it
runs properly and economic all y. The condition
of your veh icle not on ly affects its safety and
ability to hold its va lue, it a lso affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

188 Driving and en vironm ent
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converter have to
reach their optimal
operat ing tempe ratu re to
reduce fuel consumption and noxious emis­
sions effect ively .
Just after starting, a cold engine in a mid-size
car only achieves a f uel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a m ile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 m iles (4 km),
the eng ine is at its proper operat ing tempera­
ture and fue l economy has reached a no rma l
l eve l. So you can see that you sho uld avoid
short tr ips wheneve r possib le .
The
o ut sid e temp era ture is also critical in this
r egard. Your car consumes more fuel in the
winter than in the summer.

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after
purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
A WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 189
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 178. Test the
brakes carefully each time you wash the
veh icle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

could scratch your vehicle's pa int or w in­
dows .
- Never wash your car in bright sunlight.
Drops of water act as magnifying lenses
and may damage your paint.
- When you wash your car in the w inter: if
you r inse your vehicle w ith a hose, be
careful not to aim the stream of water
direct ly at locks, or at door or hatch
openings - they can free ze shut.
- Never use sponges des igned to remove
i nsects, or any kitchen scouring sponges
or similar products. They can damage
you r paint finish.
- Never use a dry cloth o r sponge to clean
the headligh ts. On ly use we t cloths or

It i s best
to use soapy wate r.
- You sho uld remove debris (su ch as in­
sects) from the head ligh t lenses on a
r egular basis, for example when refuel ­
ing your vehicle . Never use a dry cloth or
sponge to clean the head lights. Only use
wet cloths or sponges to prevent
scratches.
It is best to use soapy water.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system. In
some areas, wash ing vehicles outs ide of
these facilit ies is prohib ited.
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 powe r washe r, make sure
yo u have re ad an d u nderstood the WARN-
Cleaning and protec tion 19 1
INGS ¢ A in General information on
page 189 .
~ Always follow the operating instr uctions for
the power washer.
~ Make sure that the jet on the spray hose pro­
duces a "fan shaped sp ray" .
~ Do not hold the sp ray nozzle too close to
soft mater ials .
Never use a pow er washer to clean the power
top itself.
Keep a distance from soft materia ls s uch as
rubber hoses or insulating material as well as
sensors and camera lenses.
When cleaning the vehicle with a power was h­
er
always follow the operating instructions .
This applies part icu larly to the operating pres­
sure and the spraying d istance. Do not point
the spray d irectly at the seals around the s ide
windows, around the doo rs, on the rea r lid or
o n the powe r top. Likewise, do not po int it di­
re ct ly at tires, rubbe r hoses, insulat io n ma te ­
ria l or senso rs
¢ page 193. Hold the spray
nozzle at leas t 1.3 ft (0. 4 m) away from the
vehicle.
Do no t use a high-p ressu re power was her to
remove snow and i ce .
Do not use a jet which sprays water in a d irect
stream o r one that has a rotat ing jet.
Water temperature should not exceed 140 °F (60
°() .
A WARNING
Neve r wash t ires with a jet t hat sprays wa­
ter in a direct stream . Thi s could cause in­
v isi ble d amage to the t ire s and weaken
them, even if the spr ay is from a re lative ly

192 Cleaning and protection
-To a void damaging yo ur vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft
mater ials like rubber hoses, p lastic parts
and sound-deaden ing mater ials as well
as sensors and camera lenses . Never aim
the spray head at t he same po int for a
l ong time. This also app lies to cleaning
headlights and painted bumpers . Re­
member: the cl oser the nozzle is to the
su rface o f the materia l, the greater the
stress on the mate rial.
Caring for vehicles with matte finish
paint
Ap plies to vehicles: with matte finish pa int
Vehicles with matte finish point require spe­
cial core due to the characteristics of the
poin t.
Washing by hand
To avoid damag ing the pa int when wash ing,
f irst remove dust and large particles from
your ve hicle . Insects, g rease spots and finger­
prints are best removed with a special cleaner
for matte finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too m uch pressure.
R inse the vehicle t ho roughly with wa ter. Clean
the vehicle sta rting at the top and working to­
ward the bottom using a
neutral shampoo
and a soft mi crofiber cloth . Stop frequently to
rinse t he cloth thoroughly.
C lean the w heels and sill panels last. Use a
clean
s ponge on these areas .
R in se the veh icle tho roughly aga in and let i t
a ir dry . If there are any wa ter spots, t hey ca n
be removed using a
leather cloth.
C lean again with t he special cleaner for matte

Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded g asoline blende d with
alcohol o r MTBE (commonly re ferred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index mus t be 87 A KI or higher.
- Blend must contain no mor e than 3% me th-
anol.
- Blend must contain more than 2% co-sol-
ve nts .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knoc k index must be 87 AKI or higher .
- Blend must not conta in mo re than 10%
ethanol.
Blend of ga soline and MTBE
- Anti-knoc k index must be 87 AKI or high er. ll-

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 203
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, built-up carbon deposits can rob yo ur
