with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo ­
rarily. 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 21. •
Ant"-Slip Regulation 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 266, 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 262, fig. 232 button . When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front-wheel drive a deactivated ASR automatically re-activates
itself at a speed of 40 mph (70 km/h) .
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 262, fig. 232. With the ASR deactivated,
the ESP check light comes on, see=>
page 18. The message ASR off
appears in the display as well. On vehicles with front-wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons . Vehicles with all -wheel drive: the ASR can be deactivated
at any speed .
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
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .

Wheel bolts
Wheel bolts must always be tightened to the correct
torque.
The design of wheel bolts is matched to the factory installed rims. If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
wheels are fitted securely and that the brake system functions
correctly.
In certain circumstances, you may not use wheel bolts from a
different vehicle - even if it is the same model~
page 374.
& 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 specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under
a variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of 55 or
less in the tire's size designation. The numeral represents the ratio
of the tire's sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-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
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 323, "Checking tire pressure" .
What you can do to avoid tire and rim damage Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires. ..,

After changing a vvheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
-Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Drive at reduced speed until you have the tightening torques
checked. a
