Your vehicle is equipped with a S tronic transmission, also called a
double-clutch system/transmiss ion.
Power is transferred between the engine and the transm ission by
means of two independent clu tches. They replace the torq ue
converter of conventional automat ic transmiss ions and allow the
vehicle to a cce le rate witho ut a no ticeable b reak in the powe r flow .

The selector lever lock is effective only when the vehicle is stationary
and at speeds below 5 km/h. At highe r speeds, the lock in the N posi­
tion is automatically switched off.
The selector lever is not locked when rapid shifts are made through
the N position (e.g . from R to D) . T h is allows you to "rock" the vehicle
if it becomes stuck. If the lever is in the N position for more than
1 second with the brake pedal not depressed, the selector lock
engages automatically.

Launch Control Program
The Launch Control Program permits maximum accelera­
tion.
In order to use Launch Control, the ASR (Anti-Slip Regula­
tion) must be disabled. When ASR is disabled, the ESP
warning/indicator light in the instrument cluster illumi­
nates. So that Launch Control can be used, the engine must
be at operating temperature and the steering wheel must
not be turned.
- With the engine running, briefly press the ESP button. The
message "ASR off' appears in the instrument cluster

Intelligent technologyL ______________________________________ _
the drive wheels on one axle is detected (e.g . on slippery ground on
one side),
the spinning wheel is braked, thereby transferring power to
the other drive wheel or wheels (all -wheel drive) . This is done up to a
speed of about 60 mph (100 km/h). Noises from the brake system
signal that wheel sp in is being controlled .
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface with
less grip, gradually increase the pressure on the accelerator pedal
until the car starts to move. The wheel less ab le to transfer power
spms .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operat ional and behaves in the same way as a vehicle
without EDL .
As soon as the brake has cooled down, EDL switch es on again auto­
matically.
Electronic limited slip differential*
In vehicles w ith front wheel drive*, an electronic lim ited slip differen­
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. This mini­
m izes sliding on the front wheels and enables precise and neutral
driving through curves. The electronic limited slip differential does
not engage when d riving in wet conditions or snow.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL and the ele ctronic limited slip differential working,
the drive wheels can spin and reduce your ability to control your
ca r. -Risk of crash!
& WARNING (continued)
• The increased safety afforded by EDL and the electronic limited
slip differential does not mean that you can take safety risks .
Always adapt your driving style to the road conditions and traffic
situation.
[I) Tips
If a fau lt occurs in the ABS, the EDL is also not f unct ioni ng. This is
indicated by the ABS warning light=>
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabili zation program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from sp inning by adjust ing the engine
power to match the amount of grip available from the road surface.
How the system works
ASR performs automatica lly, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the speed
of the driven wheels. If the wheels start to spin, the engine torque is
reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range.
The ASR works in conjunction with the ABS. If a malfunction shou ld
occur in the ABS, the ASR w ill also be out of action .
[I) Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can .,

& WA RNING (conti nu ed )
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
pa ssing through water, dr iving 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 te st. Brakes will dry and ice coatings
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 al so affect br aking efficiency. Clean
off accumulated salt coating from brake disc s and pads with a few
careful brake applic ations.
• If you damage the front spoiler , or if you in stall a different
spoile r, be sure the air flow to the front brakes is not obstructed.
Otherwi se th e brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an inc reased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop .
.J
Brake booster
T h e brake booste r adds ext ra braking p ower.
The brake booster works with vacuum pressure which is created on ly
w hen the eng ine is ru nnin g=>&.
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake boo ster i s not working , for example when towing
your veh icle , or because the brake booster has somehow been
& W ARNING (continued )
damaged , the brake pedal must be p ressed considerably harder to
make up for the la ck of booster assi stan ce. •
Functioning of Anti-Lock Brake System
{ABS)
ABS prevents the wheels from l ockin g up under br aking.
Th e ABS contr ibutes effectively to vehicle co ntrol s ince it prevents t he
w heels from
locking when the brakes are applied . This means that the
veh icle rema ins steerable and is less likely to skid .
With ABS you do not need to pump the brake. Just hold the brake
pedal down .
However, do no t expect that the ABS shortens bra king d istance under
all circumstances . When dr iv ing on grave l or on newly falle n snow on
top of icy s urfaces, braking d istance may be even longer, therefo re,
under these circumstances, it is especially important that yo u drive
slowly and with g re at c are.
How the ABS system works
An au tomatic c hec k is made when a speed of about 4 mp h (6 km/ h) is
reached. When t his happens, a pump ing noise can be heard.
If an ind ivi dual wheel begi ns to rot ate too s low ly in relat ion to ve hicle
speed and tends to loc k, t he ABS automatically reduces brake pres­
s ur e to p revent t hat wheel from lo cking.
T hi s au tomatic adjustment p rocess w ill cause a
s light vibration of
the bra ke pedal and some noises to a lert you that vehicle speed must
be adapted to ex isting road and traffic co nditions .
& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving ...

The ABS cannot overcome the laws of physics .
[ i J Tips
• If ABS is not funct ioning properly, a warning light will come on .

Brake assistant
The broke assistant is designed to achieve the optimum
br oking effect.
Th e b rake ass istant he lps to inc rease t he effective brak ing powe r and
thus to ac hieve a shorter stopping distance.
If the driver presses the
bra ke ped al ve ry qu ickly, the b rake assistant au toma tically bo osts the
brak ing force to the max imum level, up to the point where the anti­
lo ck brak e function (ABS) in tervenes to stop the whee ls from l ocking.
You should then keep the brake pedal pressed unti l the vehicle has

as soon as you re lease the b rake pedal.
Th e brake assistant will not be operative if there is a ma lfu nctio n in

& 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 th e vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so always
