Driv ing off
When driving off, always be sure to keep road conditions in mind as
you acce lerate. If one d rive w heel spins because it is on a surface with
less grip, gradua lly inc rease the press ure on the accelerator pedal
un til the car sta rts to move .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads o n this whee l, t he EDL cuts out tem po­
ra rily. The vehicle rema ins operat iona l a nd be haves in the same way
as a ve hicle wit hout EDL.
As soon as the bra ke has coo le d down , ED L swit ches on again au to­
matically.
& WARNING
• When accelerating on slippery surfaces , such as on i ce or snow ,
alway s be careful when depre ssing the accelerator pedal. Even
with the EDL work ing , the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety ri sks . Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
If a fa ult occurs i n the ABS, the EDL is also not f unct io ni ng . This is
indic ated by t he A BS war ning ligh t=>
page 17.
Anti-Slip Regulation System (ASR)
The Anti- S lip Re gula tio n Sy stem preven ts the dr iven
w heels from spin ning w hen t he car is accelerating .
General notes
The Anti-S lip Reg ulation Sys tem (AS R) is in tegr ate d in the ele ctroni c
stabilization program (ESP) . When the ve hicle starts up and acceler­
at es, the whee ls are p reven ted from sp inning by adjust ing t he engine
power to match the amount of grip avai lable from the road surface.
How the system works
ASR performs automatically, i.e. witho ut the driver 's intervent ion.
W ith the a id of t he ABS sensors=>
page 246, ASR moni to rs the speed
of the dr iven wheels. If the wheels start to spin , th e engine torque is
redu ced a utomatically unti l the t ires find enou gh gr ip to lock onto
the road surface. T he system is active across the entire speed range .
Th e ASR works in conjunction with the ABS. If a malfunction sho uld
occ ur in th e ABS, th e AS R w ill also be out of action.
Activating
The ESP is automatically activated whe n the engine is started and it
performs a se lf-test. You can act ivate a deact ivate d ASR if required by
press ing the=>
pag e 242, fig. 201 button. Whe n it is act ivated, t he
message
ESP/ASR on appears briefly in t he disp lay. Vehicles with
front-wheel d rive a dea ct iva te d ASR a uto mat icall y re-ac tiva tes i tself
at a speed of 40 mp h (70 km/h) .
Deactivating
You can deact ivate t he ASR if required by pressing t he button (for less
t han 3 se conds) =>
page 242, fig . 2 0 1. Wi th the ASR dea ct ivated, the
ESP check light comes on, see=>
page 14. The message ASR off
appe ars i n the di sp la y as wel l. On vehicles wi th fro nt-whee l dr ive:
deactivation is possible only up to 30 mph (SO km/h) for safety
reas ons. Vehi cles w ith all -wheel drive: the AS R can be deac tivated at
any speed. ..

Low brake fluid l evel
Ma lf u nctions can occ ur in the brake system if the brake fluid level is
too low . T he brake flu id level is monitored e lec tron ically .
Brake lining wear statu s
Brake lining wear may be checked by visua l inspection of the condi­
t ion of t he brake pads through the open ings in the whee l. If neces ­
sary, the wheel may be removed fo r thi s inspection~
page 320,
"Changing a whee l".
& WARNING
• You should p erform braking maneuvers for the purpo se of
cleaning the brake system only if road condit ions permit. Other
road u sers must not be put at risk - you may cau se an accident!
• Befo re descending a steep grade, reduce speed and sh ift t rans ­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often. Th is could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the b rakes " by resting your foot on the pedal when
you do not intend to brake. Thi s may cau se the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced. In winter ,
ice can accumulate on the brake pads , linings, discs and drums.
Carefully apply brakes for a test. Brake s will dry and ice coating s
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt-covered roads
without using your brakes can also affect brak ing efficiency. Clean
off accumulated salt co ating from brake disc s and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you in stall a different
spoiler , be sure the air flow to the front brakes is not obst ructed.
Otherwi se the brake system could overheat reducing the effective­
ness of the entire brake system .
& WARNING (c on tinued )
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping di stance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop. •
Brake booster
The brake booster adds extra brakin g po wer.
Th e bra ke booster wor ks with vacuu m pressure which is created on ly
when the eng ine is running ~& .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working , for e xample when towing
y our vehicle , or be cause the brake booster has somehow been
damaged , the brake pedal must be pressed considerably harder to
make up for the lack of boo ster assistance. •
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wh eels from locking up under braking .
The ABS co ntrib utes effe ctive ly to ve hicl e con tro l s in ce i t preven ts t he
wheels from
locking when the brakes are applied . This means that the
vehicle remains steerable and is less likely to s kid.
With ABS you do not need to pump the brake. Just hold the brake
pedal down.
However, do not expect t he A BS to sho rten b raking di stan ce u nder all
circumstances. W hen driving on grave l or on newly fa llen snow on top
of icy s urfaces, braking distance may be even longer, therefore, under .,_

How the ABS system works
An au tom ati c c heck is m ade w hen a speed of about 4 mp h (6 km /h) is
reac hed. When th is happens, a pump ing no ise can be heard.
If an indivi dual w heel beg ins to rot ate too s low ly in relat ion to vehi cle
speed and tends to lock, t he A BS a utomat ically reduces brake pres­
sure to prevent that w heel from loc king .
Thi s au tom atic adju stm ent pr oces s w ill c au se a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be ad apted to exis tin g road and traff ic c ondi tio ns.
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i J Tips
• If A BS is no t fu nct ion ing prope rly, a w arn ing ligh t will come on .
See
~ page 17 .
• If a f ault o ccur s in the A BS, the EDL is also not func tio ning. T his is
ind icated by the ABS war ning light.
Brake assistant
--
The brake assis tan t is d esign ed to achie ve the opt imum
b raki ng eff ect.
The b rake ass istant he lps to increase the effective braking power and
t hu s to ac hi eve a shorter stopping dis tance . If t he dr iver p re sse s t he

Yo u should t hen kee p the brake pedal pressed unti l the ve hicle has
bra ked to the required speed. The bra ke ass istant switches itself off
as soon as you re lease the brake pedal.
The brake assistant will not be operative i f th ere is a ma lf u nction in
t he A BS.
& 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. Increa sed risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed .•

steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when turning the steering wheel at low
speeds (for example when parking), - more effort will be required
than usual.
• Be aware of the different than usual steering response and adjust
your steering force accordingly.
• Have the prob lem checked and set right by an Audi dealer as soon
as possible.
[ i ] Tips
• When the engine is running, never hold the steering wheel turned
all the way to the right or to the left for longer than 15 seconds . The
power steering pump will overheat the hydraul ic fluid if you keep
holding the steering wheel turned all the way . This is likely to damage
the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for examp le, while be ing towed), you will still be able
to steer the vehicle. However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydra ulic fluid. The power steering reservoir is the one located most
forward on the left side of the engine compartment=>
page 280. The
correct fluid level in the reservoir is important for proper functioning
of the power steering . •
A pp lies to veh icles: with All W heel Dr ive
Driving with your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels . This
happens automatically depending on your driving style and the road
conditions at the time . See also=:>
page 243, "Electronic different ial
lock ( EDL)".
Winter tires
When driving in the winter, your vehicle with A ll Wheel Drive has an
advantage , even w ith regular t ires . In winter road condit ions it may
be advisable to mount winter tires (or all-season tires) fo r improved
dr iveability and braking: these tires must be mounted on
all four
wheels.
See also =:> page 311, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally also
applies to vehicles with A ll Whee l Drive=:>
page 312, "Snow chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same size .
Also avoid tires with different tread depths . For details see page
=:>
page 307, "New tires and replacing tires and wheels ".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle . It is therefore best to avoid rough tracks and uneven
terrain as much as possible. Also refer to=>
page 252.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.

It is in precisely these situations 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 switched off. This
red uces 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 remote key or power seat adjust­
ment, may not be avai lab le. The convenience functions wi ll be ava il­
able again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off o r
use other MMI functions, the battery is being discharged.
If starting capability is jeopard ized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes .
The warning indicates that the system will be turned off automati­
cally after 3 minutes. If you wis h to continue using the funct ions, you
have to start the engine.
With the engine running
Although electrica l energy is generated when the vehicle is being
dr iven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed and
the battery's state of charge is not optimal.
To bring the energy balance back into equilibrium, consumers which
req uire especially large amounts of energy are temporarily cut back
or switched off . H eating 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
engine idle speed the addit ional energy required is generated and the
battery is charged. •
Driver notification in the instrument
cluster display
If battery powe r drops into the range where it can limit the ability of
the engine to start, this is shown in the instrument cluster display
w ith the following driver message:
1 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
eng ine may be limited. As soon as you start driving again, the battery
will be recharged and the notification will go out.
Driver notification appears and goes out again
If this driver notification appears after the ignition is turned on or
wh ile driving and it goes out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not go out
again
If this dr iver not ificat ion appears after the ign it ion is turned on or
whi le driving and does not go out again, the battery's state of charge
is not in the optimal range. Starting ability is restricted . Have the
battery checked as soon as possible at a dealership.

-With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the whee ls towards the curb .
- Apply the parking brake.
- Move the selector lever to
P.
When restarting after parking:
- Apply the foot brake.
- Start the eng ine .
- M ove the selector lever to
D.
-Release the parking brake and slowly pu ll out and away
from the wheel chocks .
- Stop and have someone retrieve the wheel chocks .
[ i ) Tips
If you move the se lector lever of the automat ic t ransm ission to P
before applying the parking brake and before blocking the whee ls,
yo u may have to use mo re force later to move the leve r out of t he
P
position. •
