Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit
uations such as when the vehicle is oversteering
a nd understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
Ji) i n d icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC :
Anti-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Brake assist system
The brake assist system can decrease brak ing dis
tance . It increases brak ing power when the d river
presses the brake pedal q uick ly in emergency sit
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small.
Anti-slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in sp inning a nd adapts the force to the road
conditions . T his makes it easie r to sta rt, acceler
a te and dr ive up h ills.
Electronic differential lock (EDL)
The EDL brakes w heels that a re spinning and
transfers the drive power to the other drive
wheel or whee ls if t he ve hicle is equipped with a ll
wheel drive*) . T his funct ion is no t av ail able at
h igher spee ds.
134
In extreme cases, EDL automat ically switches off
to keep the b rake on the bra ked whee l from over
heating. The veh icle is still working correct ly. ED L
will switc h on again automatically when condi
tions have returned to normal.
Steering recommendation
The E SC he lps to stabili ze the vehicle by changing
the steer ing torque.
I n veh icles with dyn amic steer ing *, ES C also
helps to sta bilize the s teer ing in cr it ic al situa
tions.
Selective wheel torque control
Se lective wheel to rque cont rol is used when d riv
i ng on curves. The fron t whee l on the ins ide of
t h e curve or both wheels on t he i nsi de of the
curve are braked se lective ly as needed. This al
l ows mo re precise driving in c urves.
Automatic post -collision braking system
The "a utomat ic post-collis io n braking system"
c a n help to reduce t he risk of sliding and of addi
tiona l co llisions after an acc ident. If th e airbag
contro l modu le de te cts a collision, t he ve hicle is
bra ked by the ESC.
The veh icle does not br ake automatically if:
- the dr iver presses the acce lera tor pedal, or
- the ESC, the brake system or the veh icle electri-
cal system are not functioning.
&_ WARNING
- The ESC and i ts integ ra ted systems cannot
overcome the lim its imposed by natura l
phys ical laws. This is es pec ially impo rtan t
o n s lippery or we t road s. If the sy stems be
gin ac ting to s tabilize yo ur vehicle, you
should immediately a lter your speed to
match the road and traffic conditions . Do
not let t he inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please note the r is k of a coll is ion increases
when dr iv ing fast, especially t hrough c urves
and on sli ppery or wet roads, and when dr iv
ing too close to objects ahead . T he ESC a nd
its integrated systems cannot always

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
I t is becoming increasing ly more and more diffi
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car wh ich you can only reach
through the eng ine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs for
you, s ince your dealer has the proper tools, the
;;§ correct bu lbs and the expert ise .
