Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors=>
page 245. If a not iceab le
slip is detected at the wheels (e.g. on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
Electronic limited slip differential
In vehicles w ith front wheel drive *, an e lectron ic lim ited slip d ifferen­
tial engages when driving on curves . The brakes are applied spec ifi­
cally to the front wheel that is on the inside of the curve. T his m ini­
m izes sliding on the front wheels and enables precise and neutral dr
iv ing t hrouge curves. The electronic lim ited slip differentia l does
no t engage whe n driving in we t cond it io ns or snow.
& WARNING
• Wh en acc elerating on slipp ery s urface s, such a s on ice or snow,
always be careful when depre ssing the accele rator pedal. Even
with the EDL and the electroni c limited slip differential working,
the dr ive wh eels can spin and reduce you r ability to control your
c ar . -Ri sk of cra sh!
• The increased safet y afforded b y EDL and the electronic l imited
slip differ ential d oes not mean th at you can take safety risks .
Alw ay s adapt your d riving st yle to the road c onditions and traffi c
si tuation.
[ i ] Tips
If a fa ult occurs in the ABS, the EDL is also not funct ioning. This is
ind icated by the ABS warn ing light=>
page 16 . •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is a ccelerating.
General notes
T he Anti-Slip Regu lation System (ASR) is in tegrated in the electronic
stabilization program (ESP) . When the veh icle starts up and acceler­
a tes, the wheels are preven ted from sp inning by adjust ing the engine
power to match the amount of grip ava ilable from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervent ion.
With the a id o f the ABS sensors=>
page 245, ASR moni tors the speed
of the driven wheels. If the wheels start to spin, engine torque is
reduced automatically unti l the tires find enough grip to lock onto
the road s urface. The system is active across the entire speed range . .,

Functioning of Anti-Lock Brake System
(ABS}
ABS prevents the wheels from locking up under braking.
The ABS contributes effectively to vehicle control since it prevents the
w heels from
locking whe n the brakes are applied . This means t hat t he
vehicle rema ins steerable and is less likely to skid.
With ABS you do not need to pump the brake. Ju st hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance under all
circu mstances. When d riving on gr ave l o r on new ly falle n snow o n top
of icy s urfaces, braking distance may be even longer, therefore, under
t he se c ir cu mstances, i t is especially importa nt that you dr ive slowly
and with great care.
How the ABS system works
An a utomat ic check is made when a speed of about 12 mph (20 km/h)
is reached. When this happens, a pumping noise can be heard.
If an individ ual w heel beg ins to rotate too slow ly in relat ion to vehicle
speed and tends to lock, t he ABS automat ic al ly reduces brake pres­
sure to prevent t hat wheel from locking .
Thi s automatic adjustment process w ill cause a
slight vibrat ion of
t he bra ke ped al and some noises to aler t you th at vehicle s peed mus t
be adapted to existing road and traff ic conditions.
& WARNING
Although the ABS is very effective , always remember that braking
capability i s limited by tire traction . Always adjust your driving
speed acco rding to the road and traffic condition s. Do not let the
extra safety afforded by the ABS tempt you into taking extra risk s.
T he ABS cannot overcome the laws of physics .
Controls and equip­ ment Safety first Vehicle operation
(I] Tips
•
If ABS is no t fun ct io ni ng prope rly, a wa rning light will come on .
See =>
page 16.
• If a fault occurs in the A BS, the EDL is also not functioning . This is
indicated by t he ABS warn ing light .•
Brake assist
Brake assist is designed to achieve the optimum braking
effect.
Bra ke ass ist helps to i ncrease the effe ctive br aking power and thus to
achieve a shorte r stopping distance . If the d river presses the brake
peda l very quickly, brake assist automatically boosts the bra king
force to the max imum level, up to the po int whe re the anti-lock b rake
function (ABS) intervenes to stop t he wheels from locki ng . You
should then keep the br ake peda l pressed unti l the ve hicle has braked
to the required speed . Brake ass ist switches itself off as soon as you
re le ase the br ake pedal.
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow the vehicle ahead of you too clo sely. Increased ri sk of an
accident cannot be compensated for even by brake assist , so
alway s maintain a safe speed. •

Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed.
Power steering will not work if the engine is off. As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing), -more effort will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set right by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the right or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt

vi dual components. It regulates consumption, so that more electrical
energy is not being used than is being generated and ensures an
optimal state of charge for the battery .
[I] Tips
• But even energy management cannot negate the limits of physics.
Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 249, "Driver notification in the instrument cluster display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
Th e battery is severe ly taxed in short-distance driving, in city traffic
and during the cold time of year. Abundant electrical energy is
required, but only a little is generated.
It is also critical if the engine
is not running and electrical components are turned on. In this
instance energy is being consumed but none is being generated.
It is in prec ise ly these sit uations that you will notice energy manage­
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or weeks,
electrical components are gradually cut back or sw itched off. This
reduces energy consumption and maintains starting capability over a
longer period.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remo te key or power seat adjust­
ment, may not be available. The convenience functions will be avail­
able again when you turn on the ignition and start the engine.
W ith the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged .
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes.
Th e warn ing indicates that the system will be turned off automati­
cally after 3 m inutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens most ly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
T o br ing the ene rgy balance back into equilibrium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heating systems in particular require a great deal of
energy .
If you notice, for example, that the heated seats* or the
heated rear window are not heating, they have been temporarily cut
back or switched off. These systems will 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. This is normal and not a cause for concern. By increasing
eng ine id le speed the additional energy required is generated and the
battery is charged. •

fluid to clean the d isplay.
0 Note
T o avoid scratch ing the MMI display, you should never clean it dry.•
MMI control console
-First clean the MMI control console with a brush to
remove dust from the housing.
- Then wipe the MMI control console with a clean, soft,
slightly damp cloth.
The MM I control console should be cleaned with a brush fi rst so that
no dirt is trapped between the buttons and the housing. We recom­
mend g iv ing the MMI control console a final wipe with a cloth moist­
ened with water and dish washing detergent.
0 Note
To prevent damage, make sure that no fluid ever gets into the MMI
control console. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
alumi num surfaces. Chrome care products and alkaline cleaners will
attack aluminum surfaces and can damage them over time .
& WARNING
Always read and heed all WARNINGS and other information
=:>page 260. •
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g . seats, door tr im panels, etc.) should
be cleaned at regular intervals with a vacuum cleaner . This removes
surface dirt particles wh ich could become embedded in the fabric
through use. Steam cleaners should not be used, because the steam
tends to push the d irt deeper into the fabric and lock it there.
Normal cleaning
Generally, we recommend using a soft sponge or a lint-free
microfiber cloth to the clean fabric. Brushes should only be used for
carpets and floor mats, since other fabric surfaces could be harmed
by brushes.
Normal surface stains can be cleaned using a commercially available
foam cleaner . Spread the foam on the surface of the fabric with a soft
sponge and work it in gently. Do not saturate the fabric. Then pat the
foam dry using absorbent, dry cloths (e .g. m icrofiber cloth) and
vacuum it after it has dr ied completely.
Cleaning stains
Stains caused by beverages (e.g. coffee, fru it juice, etc.) can be
treated with a mild detergent solut ion. Apply the detergent solution
with a sponge. In the case of stubborn stains, a detergent paste can
be applied d irectly to the stain and worked into the fabric. After­
wards, use copious amounts of clean water to remove the remaining _..,

consider if children, animals or other factors might prove to be partic­
ularly hard on the leather.
By contrast, leather types that are covered by a colored finish layer
are more durable. This has a positive effect on the leather's resistance
to wear and soiling in daily use . On the other hand, the typical charac­
teristics of natural leather are barely or not apparent . However, this
does not mean that the leather itself is of inf erior quality.
Care and handling
Because of the exclusive nature of the types of leather that Audi uses
and the ir un iqu e properties (such as sensitivity to oils, grease, so iling,
etc.), you will need to be somewhat careful with these leathers, and
a certain type of care is required. For example, dark clothing mate­
ria ls can disco lor leather seats (especially if such clothing is damp and
was not dyed correctly). Dust and dirt particles in pores, folds, and
seams can have an abrasive effect and can damage the leathe r
surface as well as weaken seams .
Th e leather should be cleaned regu larly as needed. After having been
used for a relatively long time, your leather seats will acquire a rich
aged finish. This is a characteristic of natural leather and a sign of
true quality.
In order to ma intain the value of this natural product over the life of
your vehicle, you should fo llow the recommendations below:
0 Note
• To keep your leather from bleaching out, do not allow it to be
exposed to bright sunlight for long periods of time . If you have to
leave the vehicle parked outside for long periods, cover the leather to
protect it from direct exposure to sunlight.
• Sharp objects on clothing, such as zippers, rivets or sharp pieces
on belts can leave pe rmanent scratches or scrape marks on the
surface of the leather.
W Tips
• After each time you clean the leathe r and at regular intervals, use
a leather preservative cream that contains UV-blockers and that
wor ks into the leather. This cream will nourish and moisturize the
leather, helping it to breathe and s tay supple . It also helps to build up
a protect ive coating on the surface.
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick , shoe
polish, etc. as soon as poss ible.
• Preserve the color of the leather as needed by using a special
colored leather care cream to touch up areas of uneven color .•
