'-----------------------------------------------
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. ..

• Snow chain s are available in different sizes. Always make sure
to follow the instructions provi ded by the snow chain manufac­
turer.
• Wh en driving with snow cha in s never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulations.
0 Note
• Remove snow chains before d riving on roads not cove red w it h
snow to avoid damaging t ires and wearing t he snow chains down
unnecessar ily.
• Snow chains, which come into direct contact wi th the wheel rim,
can scratch or damage it. The refore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos it ion o f the snow cha ins afte r
driving a few yards and correct if necessary . Follow the instructions
from t he snow chain man ufacturer when doing so .
• If the Adaptive A ir Suspension* sho uld ma lfunct ion, do no t mount
or use snow cha ins because t he ve hicle will be ex tremely low . If you
do drive w ith snow chains o n while the veh icle is at t his level, the
snow c hains m ight severe ly damage the whee lhouse and other parts
o f the ve hicl e.

Wheel bolts
Wheel bol ts mus t alwa ys be tigh tened to the co rrect
torque .
The design of wheel bolts is matched to the factory installed rims. If
differe nt rims a re fitte d, the correc t wheel bolt s wi th the r ig ht length
and co rrectly s haped bolt heads must be used. Th is ensures that
w heels are fitte d se cu rely and that the br ake system fun ctions
correctly .
In certain circumstances, yo u may not use wheel bolts from a
different veh icle -even if it is the same model~
page 348.
& WARNING
Improperly tightened or ma intained wheel bolts can become
loose causing los s of control, a collision and seriou s per sonal
injury .
• Always keep the wheel bolts and the thread s in the wheel hub s
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 i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .

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 302, "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 precau­
tions:
• 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 any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If you
drive under those circumstances, you should equip your vehicle with
all-season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equivalent.
Refer to=>
page 311 for more detailed information regarding winter
tires. •
Tire pressure monitoring system
Applies to veh icles: w ith tire pressure monitoring system
General notes '
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size .,
