-If it is difficult to turn the key to position
(D , turn the steering wheel back and
forth slightly to release the steering
wheel lock .
- After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up
in the hydraulic valve adjusters. This is
normal and not a cause for concern .
- If the battery is disconnected and recon­
nected, you have to hold the ignition key
in position
(D for five seconds for the en­
gine to start .
- After switching the ignition off, you can
only remove the key when the selector
lever is in the "P" (Park) position. After
that the selector lever is locked.

_& WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake, if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to accidents and serious injuries . -
Never remove the ignition key from the
ignition look while the vehicle is moving .
Otherwise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle .
- Please note that the brake booster and
power steering only work when the en ­
gine is running. When the engine off, you
must use more force to steer or brake
the vehicle . Because the usual steering
and braking capability is not available,
the risk of accidents or injuries increases.
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time. This applies partic­
ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, always park the vehi­
cle with the selector lever in the P posi­
tion . Otherwise, there is the risk that the
vehicle could roll.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes - even with the ignition
switched off. It can also switch on again
after some time if the coolant tempera­
ture rises as a result of heat buildup or if
the engine compartment is heated by
sunlight and the engine is hot .
(D Note
-If the engine has been under heavy load
for an extended period of time, heat
builds up in the engine compartment af­
ter the engine is switched off -there is a
risk of damaging the engine. For this
reason, let the engine run for at idle for
approximately two minutes before shut­
ting it off.

must use more force to steer or brake
the vehicle. Because the usual steering
and braking capability is not available,
the risk of accidents or injuries increases .
- Avoid high engine speed, full throttle,
and heavy engine load as long as the en­
gine has not reached operating tempera­
ture yet. You could damage the engine .
- The engine cannot be started by pushing
or towing.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
{D) Tips
- After starting a cold engine, there may

cause the oil pressure must first build up in the hydraulic valve adjusters. This is
normal and not a cause for concern .
- If the . indicator light blinks in the in­
strument cluster before switching the ig ­
nition off, the ignition will not switch on
again.

192 Smart T echnol ogy
Corro sion
Leaving the vehicle parked for long periods o f
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake ro­
tors and di rty brake pads.
I f you usually avoid heavy brak ing or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the
brake rotors and pads¢,& .
Brake system malfunction
if you notice that the brake pedal t ravel has
suddenly gotten larger, then a brake circuit
may have failed. Drive to your authorized Audi
dealer or qualified repair facility immediately
to hav e the problem corrected . On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary .
Lo w brake fluid level
When the brake fluid level is low, ma lfunc ­
tions in the brake system may occur. The
brake fluid level is electronically mon itored.
B rake bo ost er
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING ,~ ·
- You should only perform braking maneu­
vers to clean the brakes when the road
condit ions perm it. Never put others on
the road at risk -never forget the risk of
acc idents!
- On steep slopes, reduce the speed and
select a lower gea r or lowe r selector lev­
er position. Drive as litt le as poss ible
w hil e pressing the bra ke peda l and avoid
putt ing you r left foot on the brake pedal
whi le driving . This could cause the brakes
to overheat and impair the efficiency of
the brakes .
- Do not let the brakes "grind" by always
keeping yo ur foot on the brake peda l. This can cause the brakes to overheat
in-
,
crease wear and increase braking dis­
tance unnecessarily.
- Certain weather and operating condi­
tions such as driving through water, driv­
ing in heavy rain or driving after washing
your veh icle can impa ir the effectiveness
of the brakes . In the winter, ice may
bu ild up on the bra ke pads, rotors and
d rums. Che ck these components by b rak­
ing caref ully. App lyi ng the br akes care­
fu lly several times dries the brakes and
removes ice bui ld-up .
- The eff ic iency of the brakes can also be
impaired by driving for long stretches on roads covered with salt without using the
brakes. Yo u can remove salt deposits
from the brake rotors and pads by care­
fully applying the brakes several times.
- If the front spoiler is damaged or you in­
stall another spoiler, make sure the front
wheel brakes are ventilated properly.
Otherwise , the brake system could over ­
heat, wh ic h red uces their effectiveness .
- Failure of a brake circuit impa irs braking
performance, wh ic h increases bra king
d istance . Avoid driving the vehicle and
have it towed it to the nearest author­
i z ed A udi dealer or au thorized Aud i Serv­
ice Facility .
- Do not let your ve hicle roll w it h the en­
g ine switched off unde r any circumstan­
ces .
- If the b rake booste r is no t working, you
will have to press much harder on the b rake peda l to compensate for the lack
of the booster.
(D Note
- N ever le t the bra kes "rub" by pressing
t he pedal ligh tly when braking is not
really necessary . This causes the brakes
to overheat and increases braking dis ­
tance and causes wear .
- Before dr iv ing on a long stretch with
steep s lopes, reduce your speed and shift
to the next lower gear This makes use of
the engine brak ing effect and relieves .,.

198 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
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 an environmentally sound manner.
> Always use lead-free gaso line r=;, page 210,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
r=;, page 223, Adding engine oil > Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- 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 exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
r=;, page 223.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel

200 Driving and the environment
Vehicles use the most fuel when they are ac­
celerati ng. If you anticipate what is going to
happen next, you will need to brake less and,
thus, accelerate less. let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well be low your car's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine noise increase disproportionately at hig h
speeds . If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never dr ive faster
tha n the posted speed limit and weather con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.. Sh ut the engine off when you are not dr iving
the vehicle.
.. Do not warm up the vehicle by letting the
engine run at idle.
It is efficient to switc h off the engine when
stopped at railroad crossings and long red
lights. Turning the engine off for just 30-40
seconds saves mo re fuel than is burned by
start ing the eng in e again.
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
d rive away as soon as you sta rt the eng ine and
avoid ru nning a t high RPM wh ile the engine is
still warming up .
(D Note
Do not leave engine i dling unattended af­
ter start ing. If wa rning lights sho uld come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat , w hich could result in over­
hea ting o r othe r damage to the veh icle or
othe r property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.. Have your ve hicle serviced at regu lar inter-
vals.
Having your veh icle regu larly serviced by an
authorized Aud i dealer helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your veh icle not on ly affects its safety and
ability to ho ld its va lue, i t also affects
fuel
c onsumption .
Check your oil each t ime you fill your tank.
The amount of oi l used is re lated to engine
l oad and speed.
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certain
mileage has been driven .
You m ust drive your ve hicle abou t 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion .
T his also ap plies to fue l consumption and en ­
gine o utp ut.
(D Note
- Have your veh icle ma inta in ed properly
and i n acco rdance with the service rec­
ommendations in you r W arranty
& Main­
t enance boo klet. l ack of proper ma inte ­
nance as well as im proper use of the ve­
hicle will impair the function of the
em iss ion cont ro l system and cou ld lead
to damage.

Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
Q;) 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 fuels that fail to meet the
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specificat ions, ask your service station or
i ts 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
lems 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
M
N fuel systems clean, they are not equally effec-o
iii tive. ,...., \!) ..,.,

Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
App lies to vehicles : wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2 . The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel
higher than 5
% such as B11, B2O or B1OO are
strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni­
tion by the user.
If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­
gine's starting and running. Depending on the
season, gas stations provide ULSD No . 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was de­
signed solely for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
contain substances that will severely
damage the fuel system and the engine.
Such damage will not be covered by your
New Vehicle Limited Warranty.

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 lubricat ion and
cooling of interna l eng ine components, all in­
ternal combust ion e ngines consume a certain
amount of oil. Oil consumpt ion va ries from
engi ne to engine and may change sig nifican tly
over the life of the engine. Typically, engines
with a spec ified break -in period (see
¢ page 197) consume more oil during the
break-in period than they cons ume after oi l
consumption has stabilized.
U nder normal cond itions, the rate o f oi l con ­
s u mption depends on the q uality and viscos ity
of the oil, the RPM (revolutions 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
condensation or fue l residue a nd the oxida­
t ion level of the oil. As any eng ine is subject to
wea r as m ileage builds up, t he oil co nsump ­
t ion may increase over time until replacemen t
of worn components may be come necessary.
With a ll these variab les coming into play, no
standard rate of oil consumpt io n can be es­
tabl ished o r spe cified . There i s no alte rnative
to regu lar and frequent che ck ing of the o il lev ­
el , see
Note.
If the yellow engine oil leve l wa rning symbo l
Ill in the inst rument cl uste r lights up, you
sho uld check the oil leve l as soon as possib le
