Intelligent Technology
Intelligent Technology Electronic stabilization
control (ESC)
Description
Elect ronic stabili zation control ( ESC) suppo rts
driver safety. It red uces the risk of slipping and
improves dr iving stabi lity. ESC detects crit ica l sit­
uations such as the vehicle overstee ring and un­
dersteeri ng or the w heels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
i n g e ngine torque . When the ESC engages, the
liJ indicato r light bli nks in t he instr ument clus­
t er.
The fo llow ing systems are in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS p reve nts the whee ls from lock ing whe n brak ­
ing. The vehicle can st ill be steered even d uring
hard brak ing. Apply steady press ure to the bra ke
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is act ing to
s tabili ze the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It inc reases brak ing power when the d river
presses the brake pedal q uick ly in eme rgency sit­
uations . You must press and hold t he b rake pedal
until the dangerous si tuatio n is ove r.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the d rive wheels
begin sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler­
ate and dr ive u p hill s.
Electronic differential lock (EDL)
E DL applies the brakes to a wheel that sta rts
spi nning and t ransfe rs the d rive power to the
other driving wheels. This f unction is not availa­
b le at higher speeds.
In extreme cases, EDL automatically sw itches off
to keep the brake on the b raked wheel from over­
heati ng. The vehicle is st ill work ing correctly. EDL
86
will swi tc h on again automatically when condi ­
tions have retu rned to normal.
Power steering
The ESC can also support veh icle stab ility
t hr ough stee rin g.
Selective wheel torque control
Se lective wheel to rque con trol is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or bo th whee ls on the i nside of th e
cu rve are braked se lective ly as needed. This al­
l ows mo re pre cise dr iving in curves .
_&. WARNING
-The E SC and i ts in teg ra ted systems cannot
overcome the lim its imposed by natura l
phys ica l laws. This is es pec ially important
on s lippery or wet roa ds.
If the systems be­
gin acting to stabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and traffic conditions. Do
no t le t the inc reased safety p rovi ded tempt
you into taking risks. This could increase
y o ur r is k of a c oll is ion.
- Please note the r is k of a coll is ion increases
w hen dr iv in g fast, especially t hrough curves
a nd on sl ippery or wet r oads, and w hen dr iv­
ing to o cl ose to obje cts ahead. T he ES C and
it s i ntegrated systems cannot a lways pre ­
vent co llisions
-there is st ill a risk of acci­
dents!
- Press the accelerator peda l caref ully when
accelerating on even, slippery sur faces such
as ice and snow. The drive wheels can spin
even when these control systems a re instal­
led and this can affect driving stability and
increase the risk of a collision.
(0 Tips
- The ABS and ASR only funct ion correctly
when a ll four wheels have a sim ila r wear
co nditio n. D iffere nt tire sizes can lead to a
red uction in engin e power.
- You may hear noises when the systems de­
sc ribed are working .

Emergency assistance
{QJ Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢ page 278.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
sidewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire 's optimum performance in regard to ad­
hesion, running noise, friction and hydroplaning .
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
Finishing
.,. Reinstall the caps on the wheel bolts if neces­
sary .
.,. Store the vehicle tool kit in its designated
place .
.,. If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment
¢ page 183.
.,. Check the tire pressure on the installed wheel
as soon as possible.
.,. Check the tire pressure and store it in the Info­
tainment system.
.,. The wheel bol t tightening specification must be
90 ft lbs (120 Nm) . Check it as soon as possible
with a torque wrench. Drive carefully until then.
.,. Have the faulty wheel replaced as quickly as
possible.
278
(D Tips
- If you notice that the wheel bolts are cor­
roded 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.
Notes on wheel changing
Please read the information ¢ page 251 if you
are going to use a spare tire which is different
from the tires on your vehicle .
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90
ft lbs (120 Nm).
- 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.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then, drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information
¢page 251.
-Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
