Servotronic ® -
advanced power
steering system
The power steering systems use the power of
the running engine to allow precise steering
with little effort .
The advanced Servotronic® power steering
system senses the road speed and e lectroni­
cally adjusts power assistance to prov ide com­
fortable and safe steering response exactly
matched to the veh icle speed.
Power steering w ill not work if the eng ine is
off . As a result, the steering whee l wi ll be hard
to turn.
The power steering fluid level is checked dur ­
ing the scheduled maintenance serv ices.
([) Note
If there is an electronic malfun ct ion, ser­
votronic
w ill still f unction like a conven ­
tional power steer ing system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeab le when turning the
steer ing whee l at low speeds (for examp le
when parking), - more effo rt will be re­
qui red than usua l.
- Be aware of the different than usual
stee ring response and adjust yo ur stee r­
i ng fo rce accord ingly.
- Have the p roblem checked and set rig ht
by an Aud i deale r as soon as possib le.
(D Tips
- When the engine is runn ing, never hold
t h e steer ing whee l turned all the way to
the right or to the left for longer than 15
se conds. The power steer ing p ump w ill
ove rhe at the hydr aulic flu id if you keep
ho ld ing the steering whee l turned all the way
. This is likely to damage the power
steering system .
- If the powe r steering system sho uld fai l
entirely, o r if the engine is not runn ing
(for examp le, whi le being towed), you
w ill sti ll be able to steer the veh icle.
However,
considerably more effort will
be required to do so.
- If the power steering system sho uld
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immed iately.
- The power steering system requ ires a
specially fo rmu lated hydraulic fluid. The
powe r stee ring fluid reservoir is locat ed
in the engine compartment

T he corre ct fl uid level i n the reservoir is
impo rta nt fo r proper fu nctioning of the
powe r stee ring .
Driving with your
quattro ®
With All Wheel Drive, all four wheels are driv­
en .
Gen eral information
With A ll W heel Drive, power is distributed to
all four wheels. This happens automatically
depending on your driving style and the road
condit ions at the time. See also
Q page 190.
With the sport different ial*, powe r distribu ­
tion to the rear wheels is variable and can be
adjusted with Audi drive select*
Q page 106 .
Winter tires
When driving in the winter, yo ur vehicle with
All Wheel D rive has an advantage, even w ith
r egular tires . In wi nter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
i ng : these tires must be mo unted o n
all four
wheel s. See also q page 253, Winter tires.
Tire chains
Where tire chains are mandatory on certa in
roads, this no rma lly also app lies to veh icles

196 Intelligent technology
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electr ical energy is re­
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not run ning and elect ri­
cal components a re turned on. In th is in­
stance energy is being consumed but none is be ing generated .
I t is in precisely these situations that you w ill
notice energy managemen t actively regulat ­
ing the distrib ution of energy.
Vehicle stands for an ext ended period
If you do not drive your vehicle over a period
of severa l days or weeks, elect rical compo­
nents are grad ually cu t back o r switched off .
This reduces energy co nsu mption and main­
tains starting cap abili ty
over a longer period.
Be aware that when you unlock you r vehicle,
some of the conve nience funct ions may not
ope rate, such as the Convenience key , the re­
mote cont ro l or the power seat adjustment .
The convenience functions will be availab le
aga in when you switch on the ignition and
start the engine .
With the engine turned off
If yo u lis ten to the radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to e n­
e rgy consumpt ion, the fo llow ing warning ap­
pears in the MMI disp lay :
Please start th e engine soon or th e syst em
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inu tes .
If
you wish to cont inu e us ing the functions , you
have to start the engine.
With the engine running
Although e lec trical energy is generated when
the vehicle is being driven, the battery can be ­
come discharged. This happens mostly when
li ttle energy is being generated and a g reat
deal consumed and the battery's state of
charge is not optimal.
To b ring the energy ba lance back into equili­
brium, consumers which req uire especially
l arge amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems i n par­
ticular require a great deal of energy. If you
notice , for example, that the heated seats* o r
the heated rear window are not heating, they have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engi ne idle speed has
been increased slightly . Thi s is normal and not
a cause for con ce rn. By inc reas ing eng ine id le
speed the addi tional energy requ ired is gener­
ated and the battery is charged.

200 Driving and en vi ro nm ent
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. F ue l consumption, exhaust em issions and en ­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
d itions 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 veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
long wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
burned s tarting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . Howeve r, wear
and noxious em issions 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 .
([) Note
Do not leave engine idling unattended af ­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular inter -
vals.
By having your veh icle regu larly serviced by an
Audi dealer he lps to ensure that it runs p rop­
erly and economically. The condition of your
vehicle not only affects its sa fety and ability to
hold its value, it also affects
fuel c onsump­
tion .
Check your oil e ach time you fill your t ank .
The amount of oil 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 certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
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 contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alte r or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protec t
your vehicle's Emission Control System

pe rformance is up to the addit ional load .
Make sure that the cooling system has enough
fluid.
Tire p res sure
When tow ing a trailer, inflate the t ires of your
vehicle to the co ld tire pressure listed under
" Full load " on the label located on the dr iver's
side B-pillar (v is ible when the door is open).
I nflate trailer tires to tra iler and t ire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
lights are working properly .
Safety chain s
Be sure trailer safety cha ins are properly con­
nected from the trailer to the hitch on the ve ­
h icle . Leave enough slack in the chains to per­
mit turn ing corners . When you install safety
cha ins, make sure they w ill not drag on the
r oad when yo u are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
sepa rat ion from the hitch .

Driving instructions
Driving with a trailer always requires extra
care and consideration .
To obtain the best possible handling of vehicle and trailer, please note the follow ing :
.,. Do not tow a loaded trailer when your car it­
self is no t loaded.
.,. Be especially careful when passing other ve ­
hicles .
.,. Obse rve speed limits .
.,. Do not dr ive at the max imum permissib le
speed.
.,. Always app ly brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded t railer with an empty car re­
s ul ts in a highly unstable distribution of
weight. If this cannot be avoided, dr ive at very
low speeds on ly to avoid the risk of losing
steering contro l.
A "balanced " rig is easier to operate and con­
trol. This means tha t the tow vehicle should
be loaded to the extent possible and

pe rmissible, while keep ing the trailer as light
as possible under the circumstances. Whenev­
er possib le, transfer some cargo to the lug­
gage compartment of the tow veh icle while
observing tongue load requirements and vehi­
cle load ing considerations.
Spee d
The higher the speed, the more difficult it be­
comes for the dr iver to control the rig . Do not
drive at the maximum permissible speed . Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icu larly
when going downhill.
Reduce vehicle speed
immediately if the trail­
er shows the slightest sig n of swaying.
Do not
try to stop the swaying by acc eler ating .
Observe speed limits. In some areas, speeds
for vehicles towing trailers are lower than for regular vehicles.
A lways apply brakes ear ly . When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant t emperatu re
The coolant temperature gauge¢ page 10
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iate ly if the LEDs in
the top pa rt of the display turn o n.

A WARNING
Anyone not p roperly restrained in a mov­
ing veh icle is at a much greater risk in an
accident. Never let anyone r ide in your car

Trailer towing tips
Important to know
You r ve hicle handles d ifferently when towing
a trai le r be cause of the additional weig ht and
differen t weigh t distr ib ution. Sa fety, per fo rm­
ance and economy will great ly depend on how
carefully you load your trai ler and operate
your rig.
Be fore you act ua lly tow yo ur tra iler, p ract ice
tu rning, s topping and backing up in an area
away from t raffic . Keep practicing unti l yo u
have become completely familiar wit h the way
yo ur vehicle-tra ile r combination behaves and
responds.
Backing up is diffic ult and requires practice .
Bac king up w ith a trailer gene rally req uires
stee ring action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater d istance between your ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius .
When passing, remember that you cannot ac­ ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, a llow
plen ty of room for your t railer before cha ng­
i ng lanes again .
Avoid jerky starts, sharp turns o r rapid lane
changes .
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢

210 Cleaning and protection
Plastic and vinyl
Plastic needs special care .
Use a clean, damp cloth or sponge to remove
dust and light surface dirt. For other soil, use
a lukewarm all-purpose clean ing solution or a
mild saddle soap for vinyl trim. Remove water
spots and traces of soap w ith a clean, damp
clot h or sponge. Use a clean, soft clot h to rub
dry.
Grease, tar or o il stains can be removed w ith a
clean cloth or sponge soaked w ith all-purpose
cleane r or with a solvent designed especially
to clea n viny l.
Occasionally apply a colorless vinyl or leather preservat ive to retain the material's luster
and pliability.
.&_ WARNING
Always read and heed all WARNINGS and
other information ¢ page 206.
Aluminum trim
Use only neutral-pH produc ts to remove spots
and deposits from aluminum surfaces.
C hr ome care products and alkaline cleaners
will attack aluminum surfaces and can dam­
age them over time.
.&_ WARNING
, -
Always read and heed all WARNINGS and
other information ¢ page 206.
Touch-up paint
Minor paint damages should be touched up
immediately.
.. Use either a touch-up paint stick or spray
paint to cover minor scratches and nicks .
Your Audi dea ler has touch-up paint for minor
scratches and stone chips. Scratches s hou ld
be touched up soon after they occur to pre­
vent corrosion.
If a spot starts to rust, however, a simple
touch-up job will not be enough. The affected
surface must be sanded smooth and coated
with an anti-rust primer before the painted
finish can be restored.
The number for the original vehicle paint can
be fo und on the vehicle identification label

Windows '
Clear vision to all sides .
Clean all windows regularly to remove road
film and car wash wax buildup .
.. Remove snow from w indows using a brush.
.. Use a plastic ice scraper to remove ice from
windows and mirrors .
.. Remove other residue on the windows with
a spray •on glass cleaner.
.. Wipe the w indows dry with a clean piece of
cloth or kitchen paper towel.
T he best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer - to remove
ice from windows and mir­
rors.
Oil, grease or s ilicone residue can be removed
with
glass cleaner or silicone remover . How­
ever, wax res idue requires the use of a spec ial­
ly formulated solvent. Please contact your Au­
di dealer for adv ice on safe products for wax
removal.
Windows should also be cleaned on the inside at regular intervals .
Never dry windows with the same chamo is
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vis ion through
the windows . ..,_

214 Cleaning and protection
leathe r, whi ch has a smooth surface and
comes in various co lors .
The intensity of the color determines the v is u ­
a l charac ter istics and appearance. If the sur­
face of the leather has a typical natu ral look,
then the leather is a nappa leather that has been left in a relatively natural cond ition. This
leather offers particularly good comfort and
breathes well. F ine veins, closed grains, insect
b ites, skin folds , and subtle var iations in co lor
remain visible . These c haracteristics demon­
strate that the mater ia l is natural.
Natural nappa leather is not covered by a col­
or fi nish . It is therefore more sensitive to soil ­
i ng and wear, w hich is something you need to
consider if ch ild ren , an ima ls or othe r factors
might prove to be particular ly hard on the
l eathe r.
By contrast, leat her types that are covered by
a co lored finish layer a re mor e durable . This
has a posit ive effect o n the leather's resist­
a nce to wear and soil ing in daily use. On the
o ther hand , the typical characteris tics of na tu­
ra l leather a re barely or not apparent. Howev ­
e r, this does not mean that the leather itself
is of infer ior quality.
Care and handling
Because of the exclusive na ture of the types of
l eather that Audi uses and the ir unique prop­
erties (such as sensitivity to oils, grease, soi l­
ing, etc.), you will need to be somewhat care­
fu l w ith these leathers, and a ce rtain type of
care is required. For examp le, dark clot hing
materials can d iscolor leather sea ts (especial­
ly if such clot hing is damp and was not dyed
correctly) . Dust and d irt part icles in po res,
folds , and seams can have a n ab ras ive effect
and can damage the leathe r sur face as well as
weaken seams.
The leather should be cleaned regula rly as
needed. After havi ng been used for a re lative ly
l ong time, yo ur leather sea ts will acqui re a
ri ch aged finish. This is a charac ter istic of n at­
u ra l lea ther and a sign o f true quality . In order to maintain the val
ue of this nat ural
product over the life of your vehicle, you
sho uld follow the recommendat ions be low :
(D Note
- To keep your leather from b leaching o ut,
do not allow it to be exposed to b right
sunlight for long periods of time . If you
have to leave the ve hicle parked outside
for long per iods, cover the leather to
protect it from direct exposure to sun ­
light .
- Sharp objects on cloth ing, such as zip­
pers, rivets or sharp pieces on belts can
leave permane nt sc ratches or sc rape
ma rks on the su rface of the leather.
(0 Tips
- After each time you clean the leather and
at regular intervals, use a leathe r preser­
vative c reme that contains UV-b locke rs
and tha t works into the leat he r. Thi s
c reme will nour ish a nd moistu rize the
leather, helping it to breathe and stay
supple. It a lso helps to build up a p rotec­
tive coating on the surface.
- Clean the leat her every 2 -3 months,
and clean any a reas that get soi led .
- Remove fresh ma rks made by ballpo int
pe ns, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- P reserve the color o f the leather as need ­
ed by using a specia l co lore d leathe r care
creme to touch up areas of uneven color .
Cleaning and caring for leather
upholstery and trim
Applies to vehicles: with natural leather
Natural lea ther requires special care and at­
tention .
Normal cleaning
.. Clean soiled areas with a slightly moistened
cotton or woolen cloth . .,.

More stubborn dirt
"' More stubborn dirt can be removed using a
cloth saturated with a mi ld soap so lution (2
tablespoons mi ld liquid soap).
"'N ever allow the soap so lution to saturate
the leather, and make certa in that no water
soaks into the seams .
"' Wipe
off the soap solution with a soft, dry
cloth .
Cleaning spots
"' Remove fresh water-based spots (such as
coffee, tea, juices, blood) w ith an absorbent
cloth or paper towel.
"' Remove fresh
grease or oil -based spots
(such as butter, mayonnaise, chocolate) with
an absorbent cloth or paper towel, or use
t h e cleane r from the leathe r care kit if the
spot has not yet penetrated into the surface
of the leather.
"'U se an oil/grease dissolving spray, if
oil/
grease spots have d ried on.
"' Remove spec ific kinds of spots (ballpoint
pen, felt marker, fingernail polish , water­
based paint, shoe polish, etc.) with a spot
remover specifically formulated for leather .
Leather care
"'Every half year use an approved leather care
product (available from your Audi dealer) to
care for the leather.
"' Apply the product very sparingly.
"' Wipe it
off with a damp cloth .
