to the other drive wheel or wheels (all-whee l drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin 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 able to transfer
power spins .
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 operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, 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 risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 16. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, 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.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test. You can activate a deactivated ASR if required
by pressing the=>
page 188, fig. 158 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 188, fig . 158. With the ASR deactivated,
the ESP check light comes on, see=>
page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains

Wheel bolts
Wheel bolts mus t alwa ys be tighte ned to t he correct
to rq ue .
The design of wheel bo lts is matched to the factory installed rims. If
di fferent r ims are fitted , th e cor rect whe el bo lts wi th the rig ht l ength
and c orrec tly shaped bolt heads must be used . This ens ures that
w he els a re fitted se cur ely and th at the bra ke syste m functi ons
correctl y.
In cer ta in c ircums tances, yo u ma y not use w hee l bolts fr om a
differ ent vehicle - even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The s pecified torque for the wheel bolts is 90 ft lb ( 120 N m) with a
to lerance o f± 7,4 ft lb(± 1 0 Nm). Torque whee l bolt s diago nally.
After chang ing a whee l, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi

Low aspect ratio tires
You r A ud i is fac tory-eq uippe d w ith low aspect ra tio tire s. T hese tire s
have been thorough ly t ested and b een se lected specifica lly for your
mod el for thei r su p erb pe rf or manc e, r oad f eel an d ha nd ling under
a variety of driving con ditions . As k your authorized Audi d ealer for
m ore de ta ils.
The low aspect rat io o f th ese t ires is indicated by a numer al of 55 or
less in the t ire's size designation. The numeral rep resents the ratio
o f t he t ire's s idewa ll he ig ht in rel ati on to it s tread w idt h ex pressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
mo re.
The performan ce of low -aspe ct-ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflat ion pressure is regularly checked and ma intained. Tire pres­
sures should be checked at least once a month and always before a
long trip=> page 249, "Checking tire pressure" .
What you can do to avoid tire and rim damage L ow aspect ratio tires can be damaged mo re easily by impact with
po tho les, cu rbs, gull ies o r rid ges o n th e road, particular ly if the t ire
is underinf lated .
I n or der to mini mize th e occurrence of i mpac t da mag e to t he tires
of your vehicle, we recommend that you observe the fol lowing
pr ecaut ions :
• Always ma intain recom mended inflatio n pr essu res . C heck you r
ti re p ressu re eve ry 2,000 mi les (3,000 k m) and add a ir if neces sary .
• D rive carefully on roads with potho les, deep gullies or ridges.
T he impact from d riving th rough or ove r such obstac les can

down as far as it will go.
- Close your grip around the
end of the wrench handle for
maximum torque and turn each wheel bolt
clockwise
until it sits tight.
& WARNING
• Using force without control to speed the wheel change up can
cause the vehicle to slip off the jack and cause serious personal
injuries.
• Do not loosen the wheel bolts more than one turn before you
raise the vehicle with the jack. -Risk of injury!
[ i] Tips
• Never try and use the hexagonal socket in the handle of the
screwdriver to loosen or tighten the wheel bolts.
• If a wheel bolt sits very tight, you may find it easier to loosen by
carefully pushing down on the end of the wheel bolt wrench with
one foot only . As you do, hold on to the car to keep yourself stable
and take care not to slip.•
