2011 AUDI A3 wheel torque

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 .,

& WARNING (co ntinued )
• 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 .
[ i] Tips
• Where snow chains are mandatory on certa in roads, this normally
also app lies to ve hicles wi th A ll W hee l Dr ive.
• If snow chains are installed, the tire p ress ures s houl d not be
sto red in the tire pressure moni to ring system (TPMS) . Otherwise the
system could malfunction ~

Wheel bolts
Wheel bolts must al ways be tight ened to the c orrect
torqu e.
The desig n of whee l bolts is matc he d to the fa ct ory in stalled rims. If
different r ims are fitted, the cor rect wheel bo lts wi th t he r igh t length
and correctly s haped bolt hea ds must be used . Thi s ensures that
Safety first
wheels are fitted securely and that the brake system funct ions
cor rectly .
I n certa in circumstances, yo u may not use wheel bo lts from a
different vehicle -even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can be come
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 bolt s can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the th reads in the wheel
hub s. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolt s 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 loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolt s and thread s can be damaged and the wheel can become
loose.
0 Note
T he specified torq ue for the wheel bo lts is 90 ft lb (120 Nm) with a
t o le rance of ± 7,4 ft lb( ± 10 N m). Tor qu e wheel bo lts diagonally.
After cha nging a wheel, the torque must be checked as soon as
pos sible wi th a t orque w rench -prefer ably by an auth oriz e d Aud i
dealer or qualified workshop .•
