mode.
Electronic differential lock (EDL)
The electronic differential lock monitors the
rotational speed of the drive wheels .
General notes
The electronic differentia l lock (EDL) helps the
car to start movi ng, accelerate and climb a
gradient on surfaces providing poor or almost
no grip. Without EDL, this would be difficult,
if not impossible.
H ow the system works
The ED L opera tes automatically. It monitors
the rotat iona l speed of wheels w ith the help
of the ABS sensors¢
page 229. If a noticea
b le
slip is detected at the wheels (e .g. on slip
pery ground
on one side), the spinning whee ls
are braked and power is transferred to the
other wheels. This is done up to a speed of
about
60 mph (100 km/h) . Noises from the
brake system s ignal that wheel sp in is being
controlled.
Dri ving 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
w ith less gr ip, apply
plenty of throttle until
the car starts to move.
O verheating of br akes
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 . T he vehicle remains operational and be
haves in the same way as a veh icle w ithout
E DL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be carefu l
when depressing the acce le rator pedal.
Int ellig ent technolog y 22 7
Even with the EDL working, the drive
wheels can spin and red uce your ab ility
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 condit ions and traffic situation .
(D Tips
If a fault occurs in the ABS, the EDL is also
not functioning. This is ind icated by the
ABS warning light¢
page 18.
Anti-Slip Regulation System (ASR )
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating .
General note s
The Anti-Slip Regu lation System (ASR) is inte
grated in the Electronic Stabilization Control
(ESC). When the vehicle starts up and acceler
ates, the wheels are prevented from spinning
by adjust ing the engine power to match the
amount of grip available from the road sur
face .
How the sy stem works
ASR performs automat ically, i.e. without the
driver's intervention. With the aid of the ABS
sensors ¢
page 229, ASR monito rs the speed
of the dr iven wheels .
If the wheels start to
spin, engine torque is red uced automat ically
unt il the t ires find enough grip to lock onto
the ro ad surface. The system is active across
the entire speed range.
T he ASR works in conjunction with the ABS. If
a malfunc tion s hou ld occu r in the ABS, the
ASR wi ll also be out of act io n.
A WARNING ~
The increased safety affo rded by ASR does
not mean that you can take safety risks.
A lways adapt your driving sty le to the road
conditions and traffic situation.

sary . Follow the instructions from the
snow cha in manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains beca use the vehicle will be ex
tremely low. If you do drive with snow
chains on while the vehicle is at this lev el, the snow chains might severe ly dam

veh icles w ith all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled r ims. If different rims are fit
t e d, the cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted
secure ly an d that the brake system f unctions
correctly.
I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l
~page 32 7.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop erly t ightened.
- Never grease or oil the wheel bolts and the threads in the wheel hubs. They can
become loose w hile driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 297
-On ly use whee l bolts that be long to the
rim being installed.
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce t he
risk o f a wheel loss. If the tightening tor
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi
cle is mov ing.
If the tig hte ning torque is
too high, the wheel bolts and threads can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the whee l bolts is
120
ft l b ( 160 Nm) with a to le rance of
± 7, 4
ft lb( ± 10 Nm). Torque w heel bo lts

Low aspect ratio tires
Your Audi is factory-equ ipped with tow aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb perfo rmance, road feel
and handli ng under a var iety of drivi ng condi
tions. As k your au thori zed A udi dealer for
more de tails.
The low asp ect ratio of these tires is ind icated
by a nu mera l of
55 or l ess in the tire's s ize
designation. The n ume ra l rep resen ts the ra tio
of the tire's sidew all height in rel ation to its
tread width exp ressed in percentage . Conven
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low-aspect-ratio tire s is
particularly sensitive to improper inflation
pre ssure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and mainta ined. Tire pres-
sures should be checked at least once a .,..

After changing a wheel
A wheel change is not complete without doing the following .
• Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com
partment <=>
page 171.
• As soon as possible, have the tightening
torques
on all wheel bolts checked with a
torque wrench . The correct tightening tor
que is 120
ft lb (160 Nm).
• Have the flat tire
replaced as soon as poss i
ble.
(D 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 tighten ing torque.
- Drive at reduced speed until you have the
tightening torq ues checked.

the rim could hit the brake rotor and dam
age the rotor. Work carefully and have a
second person help you.
- When mounting tires with
unid irection al
tread design
make sure the tread pat
tern is pointed the right way
¢ page 308 .
-The wheel bolts should be clean and easy
to turn. Check for d irt and corrosion on
the mat ing surfaces of both the wheel
and the hub . Remove all dirt from these
su rfaces before remount ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in
the right direction.
Using a spare t ire w ith a tread pattern
int ended fo r use in a specific direct ion
When us ing a spa re tire w ith a t read patte rn
i n te nded for use in a specific direction, p lease
note the fo llowing:
- The direction of rotation is marked by an ar
row on the side of the tire .
- If the spare t ire has to be in stalled in the in
correct d irection, use the spare tire only
temporarily since the t ire will not be able to
a chieve its optimum perfo rmance character
ist ics w ith reg ard to aquapl ani ng, noise and
wea r.
- We recommend tha t you pay pa rticular at
tent ion to this fact du ring wet weather and
that you adjust your speed to ma tch road
conditions .
- Replace the fla t tire w ith a new one and
have it installed on your veh icle as soon as
poss ible to restore the handling advantages
of a unid irect iona l tire .
