- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

Smart Technology
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical energy is not being used than is being
generated and ensures an opt imal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­ tor light (•) appears ¢
page 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrica l energy is requ ired, but
only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In th is instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no­
tice energy management actively regulating the
d istr ibut ion of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, e lectrical components are
gradually cut back or switched
off. This reduces
energy consumption and maintains starting ca­ pability over a longer period . Some of the con­
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions w ill be available again
when yo u sw itch on the ignition and start the en­
gine.
With the engine turned off
I f you listen to the radio, for example, with the
engine turned
off or use other MMI functions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­
p la y. The message indicates that the system will
176
be switched off automatically in a moment . If
you wish to continue using the functions, you have to start the eng ine.
With the engine running
Althoug h elec trical energy is generated when the
vehicle is being driven, the battery can become
discharged . This happens mostly when litt le en ­
ergy is being generated and a great dea l con­
sumed and the battery's state of charge is not
optimal.
To bring the energy ba lance back into equilibri­
u m, consumers which require especially large
amounts of energy are temporar ily cut back or
switched
off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window a re not heating, they have been tempo­
rarily cut back or switched
off. These systems w ill
be ava ilable again as soon as the energy ba lance
has been restored.
You will also notice that engine idle speed has
been increased slightly . Thi s is normal and not a
cause for concern. By incr easing eng ine idle
speed the additional energy required is generated
and the battery is cha rged.

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your persona l dr iving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percen t. This sec tion will
give you some tips on how you can help the envi ­
ronment and your pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depending upon vehicle load and
speed, road and weather conditions, trip
length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
e rate less. Let the vehicle coast whenever possi­
ble - for example when yo u see that the next traf­
fic light is red .
Driving and the environment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fuel consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when wa iting for tra ins to pass a t railroad
crossings, or at traffic lights that have long waits
on red . Turning the engine
off for just 30-40 sec ­
onds saves more fue l than is burned starting the
. . engine again.
It takes a long t ime 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 sta rt the engine and avoid
running at high rpms wh ile the engine is st ill
warming up.
(D Note
Do not leave engine idling unatt ended afte r
starting .
If warning lights should come on to
indicate improper operation, they would go
un heeded . Extended idling also produces
heat, which could result in overheating or oth­
er damage to the vehicle or other property.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
factory -fitted contro l unit -ris k of acci dent!
- After removing the t railer hi tch, do n ot store
it in your vehicle . In case o f su dden braking,
the hi tch could fly forward and injure you or
your passe ngers.
Operating instructions
Maximum traile r weight
A trai ler for you r vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
B e sure the load in the t ra iler i s held secure ly in
pla ce to prevent it from sh ifting forw ard , back ­
war d or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving in struc tion s on page 182.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's pe rform­
ance is up to the additional load . Ma ke s ure that
t h e coo ling system has enoug h fluid.
IIJJ,
181

Trailer mode
Tire pressure
When tow ing a trailer, inflate the tires of your ve­
hicle to the cold tire pressure listed under " Full
load" on the label located on the driver's side B ­
pillar (visible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be su re trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains shou ld cross under the trai ler tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trai ler, please note the following:
.. Do not tow a loaded trailer when your car itself
is not loaded .
.. Be especia lly careful when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and contro l.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keep ing the trailer as light as possible under the
c ir cumstances. Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerat ions .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or w ind
cond it ions are unfavorab le - particularly when
go ing downh ill.
Reduce veh icle speed
immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When dr iving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the air conditioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
&_ WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Care and cleaning
Care and cleaning
General information
Regular, proper care he lps to maintain your vehi ­
cle's value.
It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from your authorized Audi dealer . Read and fol­
low the instructions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store cleaning and care products out of reach of children to reduce the risk of poi­
soning .
@ For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not dispose of leftover cleaning and care
products with household trash .
Car washes
The longer that deposits remain on the vehicle,
the more the surface may be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird dropp ings or tree
sap are best removed with plenty of water and a
microfiber cloth .
A ls o, wash the underside of your veh icle once
road salt stops be ing used for the season .
Pressure washers
When washing your veh icles with a pressure
washer, always follow the operating instructions
provided with the pressure washer. This is espe­
cially important in regard to the p ressure and
spray ing distance. Do not aim the spray directly
at seals on side windows, doors, the hood, the
rear lid or the sunroof* or at tires, rubber hoses,
184 insulating
material, sensors* or camera lenses*.
Keep a distance of at least 16 inches (40 cm).
Do not remove snow and ice with a pressure
washe r.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above 140 °F
(60 °() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the w indows and roof* are closed
and the windshie ld wipers are off. Follow instruc­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the veh icle starting from the top and work­
i ng down using a soft sponge or cleaning b rush .
Use solvent-free cleaning p roducts.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint.
Apply the p roduct using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse the ve hicle thoroughly with water. Then
clean using a neutra l shampoo and a soft micro­
fiber cloth .
Rinse the veh icle thoroughly again and let it air
dry. Remove any water residue using a shammy.
A WARNING
-On ly wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acc i­
dents.

-To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the w inter . The brakes
must be dried first w ith a few careful brake
applications.
(I) Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage to the mirrors. Power folding exterior mirrors* must only
be fo lded in and out us ing the power folding
f u nct ion.
- To prevent pa int damage, do not wash the
vehicle i n direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itche n
sponges or similar items.

- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax.
It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish pa int. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment

Fuel and Refueling
Fuel and Refueling
Fuel
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­ mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine can also be found on a label located
on the ins ide of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­ ing of 87 AKl/91 RON . However, using 87 AKl/91
RON octane fue l will s lightly reduce eng ine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 188.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade : 91 - 96 AKI
- Regular Grade: 87 -90 AKI
186
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
( methyl tertiary butyl ether)
You may use unleaded gasoline blended with a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AKI or h igher.
- Blend must not contain more than 1S% etha-
nol.
- Veh icles with flex ible fuel engine: blend must
not contain more than 85% ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you ""
