Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw)
out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
m in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 187
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds.
A lways adjust your speed and driving style to
road, traffic and weather condit ions. ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
drive r inattent io n. Instead, ESC imp roves the
poss ibility of keep ing the vehicle unde r con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inp uts to
help keep the vehicle going in the intended di ­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switc hed on all the time . In certain sit­
uat ions when you need less traction, yo u can
switch off ASR by pressing the button
[&I
c::> page 189, fig. 180. Be sure to switch ASR
o n again when you no longer need less t rac ­
t ion.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
whe n brak ing. The vehicle can sti ll be stee red
even dur ing hard braking. App ly steady pres­
s u re to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake as sist sy stem
The brake assist system can decrease braking
distance. It increases brak ing power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal until the situation is over. In
vehicles with adapt ive c ruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv­
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys­
tems beg in acting to stabilize your vehi­
cle, you should immediately change your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Do ing so will increase the risk
of a loss of veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los­
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys­
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth su rfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistan ce sys tems that cannot al­
ways he lp to re duce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi­
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht
BJ or rJlll (USA
mode ls)/ l§J (Can ada models) appears,
t here may be a malfunction ¢

192 Intelligent technology
overheat, premature wear and increased
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice ca n
accumulate on the brake pads, linings ,
discs and d rums . Carefully apply brakes
for a test . B rakes wi ll dry a nd ice coat­
ings will be cleaned off after a few c are­
f ul brake app lications .
- Dr iv ing fo r an ex tende d pe riod of time on
salt-covere d roads w ithout us ing yo ur
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
bra ke discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
over heat reducing the effectiveness of
the ent ire brake system .
- Failure of one brake c ircuit will impair
the braking capability res ulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to t he near­
est Aud i dea le r o r q ualified w ork sho p.
- Never let the vehicle ro ll to a stop w ith
the e ngine shu t off.
- If the brake booster is not working, the
brake pedal must be p ressed conside ra­
bly harder to make up for the la ck of
booster assistance.
Electromechanical
power assist, dynamic
steering
The electromechanical power assist helps the
driver when steering .
Power stee ring adapts electronically based on
the vehicle speed .
Indicator lights and messages
• Steer ing defective! Stop the vehicle
If this indicato r light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not con tinue dr iv ing . See your author ized
Audi dealer or other qualified repair facility
for assistance .
l;r-ij Steering: System fault You can continue
driving
If the indicato r light turns on and the mes­
sage appea rs, the stee ring may be more diffi­
cul t to move o r more sensi tive th an usua l. The
steering wheel may a lso be at an ang le when
driving straight .
Drive slowly to you r authorized Aud i dea le r o r
qualified wo rks hop to have the ma lf u nct ion
corre cted.
l;r,ij Dynamic steering: Initializing
If this driver message appears and t he indica­
tor light is f lashing on the instrument panel,
dynam ic steer ing* is being rei nitia lized. Afte r
sta rting the engine, the stee ring wheel will
move s ligh tly. Re- ini tiali zation mig ht be ne c­
e ssa ry if the stee ring wheel was moved h ard
to the left an d right wh ile the vehicle was not
moving . The display goes out as soon as initi ­
alization is complete.
D rive slowly to you r aut horized Audi de aler or
qualified wo rkshop to have the ma lf u nct ion
corrected.
A WARNING
Have t he dynamic stee ring * system mal ­
f u nction repa ired as soon as possib le by an
a uthorized Audi dealer or qua lified wor k­
shop - risk of accident !
(D Tips
If the . or@ indicator light on ly stays
on for a short time, yo u may continue driv­
i ng.
- The dynamic steering * sta bility systems
are not avai lab le in the event of a system
ma lf u nction.
- For add itiona l information on dynamic
steering *, refer t o

228 Tires and wheels
-If you notice unusual vibra­
tion or if the vehicle pulls to
one side when driving, al­
ways stop as soon as it is
safe to do so and check the
wheels and tires for dam­
age.
0 Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­
ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability. If summer tires are used
in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and
unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.
Glossary of tire and loading terminology
