-Aft er s tarting a col d engine, there may
be a brief period of inc reased noise be
cause the oil pressure must first bui ld up
in the hydraulic valve ad justers . This is
n ormal and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignit ion w ill switch off
after a certain per iod of t ime. Please
note that electrical equ ipment such as
exterior lights will sw itch off as well
when that happens .

Fa u lts in th e brake sy stem
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circuits may have failed~.&..
Low brak e flu id level
Malfunct ions can occur in the brake syste m if
the brake fl uid leve l is too low. The b rake fluid
l eve l is monito red electronically.
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal.
It only op
e rates while the eng ine is running or with the
i gnit ion sw itched on (hybr id dr ive*)~ .&,.
Brake lining wear statu s
Brake lining wear may be checked by visual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sa ry, the wheel may be removed for this in
spection
~ page 2 73, Changing a wheel.
.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too long or too often. This could cause the
brakes to get hot and dimin ish b raking
efficiency.
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake. Th is may cause the b rakes to
overheat, premat ure wear and increased
stopp ing distance .
- Under certain climat ic and operating
c ondit ions such as passing through wa
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
Int ellig ent technolog y 201
for a test . Brakes will dry and ice coat
ings w ill be cleaned
off after a few care
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few ca reful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the ai r
f low to the front brakes is not obst ruct
ed. Otherw ise the bra ke system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one b rake circuit will impair
the braking capab ility result ing in an in
creased stopping distance. Avoid driving
the vehicle and have it towed to the near
est a uthorized Audi dea ler or q ualified
workshop.
- Never let the vehicle roll to a stop with
the eng ine shut off .
- If the b rake booster is not working, the
brake peda l must be pressed considera
bly harder to make up for the lack of
booster assistance.

206 Driving and en vir onm ent
Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
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 gasoline i=> page 222,
Gasoline .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 236, Adding engine oil 'l=r. .
.. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert
e r and proper functioning of the engine.
A WARNING
T he temperature o f the exhaust system is
high, both when driving and after stopping
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 exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verter or heat sh ields . During driving, the
substance used for u ndercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 236.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con
verter, requir ing its replacement .
- To assure efficient operation of the Emis
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter i lluminates
i=> page 34. ..,.

208 Driving and environment
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 .
The idling phase is automatically reduced for
vehicles with the Start-Stop -System* . It is ef
fic ient to sw itch
off the eng ine in vehicles
without the Start-Stop-System* when stopped
at railroad crossings and long red lights. Turn
ing the eng ine
off for just 30-40 seconds
saves more fuel than is burned by sta rting the
engine again .
It takes a long time for the engine to wa rm up
fu lly when it is running at idle. However , wear
and nox ious 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 could resu lt in over
heat ing or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
.,. Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects
fuel
consumption. Check
your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven .
You must drive your veh icle about 3,000 mi les
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fuel consumption and en
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec
ommendations in your Warranty
& Ma in
tenance booklet. Lack of proper ma inte
nance as well as improper use of the ve
hicle will impair the function of the
em iss ion control system and could lead
t o 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 shie lds , switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo
nents.
' Fewer short trips
Fuel consumption will always be relatively
high on short trips.
... Try to avoid driving sho rt distances w it h a
cold engine .
T he eng ine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and nox ious emis
sions effectively.
Jus t after starting, a cold engine in a mid-s ize
car only achieves a fuel economy of 6-8 mi les
per gallon (30 -40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg .,..

Seasonally adjusted gasoline
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 stat ions where the sea
sonal adjustment is more likely to be made in
time.
(D Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in veh icles with flex ible fuel* en
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l* engines
can cause severe engine damage .
- 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
specifications, ask your service station or
its fuel supplier.
- 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 respons ibility of Audi and are not
covered under the New Veh icle or the

Fuel supply and filling your fuel tank 223
Ethanol fuel (Bio-ethanol)
Applies to veh icles: w it h flex ible fue l en gin e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap .
Vehicles with flexible fuel engines may be op
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un
leaded gasoline (91 AKI/ROZ 95) . T he vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in ve ry
low temperatures. This fuel evaporates again
when the engine is warmed up.
D Please warm up engine.
If the driver message appears in the instru
ment cluster disp lay, drive with a warm en
gine to reduce the oil level.
(D Note
- Never fill with methanol or with a higher
percentage of b io-ethanol than 85%
(E85). A h igher percentage of bio-etha
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fue l tank complete ly w ith un
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fuel tank comp letely with unleaded pre
mium grade gasoline and dr ive it nor
mally until the gasoline is used. See your
authorized Audi dealer if the problem
pers ists.

232 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to P (Park).
- Always let the engine cool down. Hot components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care
fully opening the hood.
- Keep children away from the engine com partment.
- Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never touch the radiator fan. The auxili
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool
ant system is pressurized and hot cool ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com
partment could start a fire.
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal in
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever of automatic trans
mission to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact ing hot parts. Tie back hair before
