2012 AUDI A6 differential

Instruments and warning/indicator lights 19
!;.!~ Electronic stabilization program
(ESP)
This warning/indicator light monitors the
electronic stabilization program.
When you sw itch the ignition on, the indicator
light
G1 turns on briefly to check the function .
If thE:
G1 indicator lamp blinks while dr iving,
the ESP or ASR (Ant i- Slip Regulation) is active ­
ly regulating.
If thE:
hJ indicator lamp illuminates, the sys­
tem has switched the ESP off.
If the indicator light
I turns on, the ESP was
switched to ESP sport mode with the button
I!]<=>
page 189. If this is case, you can reacti­
vate the ESP by switching the ignition off and
then on again . The warning/indicator light
should go out to show that the system is fully
functiona l again.
Stability program and ABS fault! See own­
er's manual
If the indicator light D] and the ABS indicator
light
m (USA mode ls) ;fl] (Canada models)
turn on and the message appears, there is a
malfunct ion in the ABS system or electron ic
differential lock . This also interrupts the ESP.
The brakes still function with their normal
power, but ABS is not active.
Drive to your authorized Aud i dealer immedi ­
ately to have the malfunction corrected .
If the battery term inals were disconnected
and re-connected, the vehicle was jump start­
ed or the battery is very weak, the ESP sensor
system goes through a learning process for
the first few yards . The warning/ind icator
light illuminates . Th e warn ing/ indicator light
goes o ut as soon as the learning process is
comp lete.

8) Anti-lock braking system (ABS)
This warning/indicator light monitors the ABS
and the electronic differential lock (EDL) .
The warning/indicator light B (USA mod­
els)
/ l(O] (Canada models) w ill come on for a
few seconds when the ignition is sw itched on .
The light will go out after an automatic check
sequence is comp leted.
There is a malfunction in the ABS when:
-The warning/indicator light does not illumi·
nate when you switch the ignition on.
- The warning/indicator light does not go out
after a few seconds.
- The warning/indicator light illuminates
while driving.
The ESP indicator light also illuminates if
there is a ma lfunction in the ABS . The mes ­
sage
Stability program and ABS fault! See
owner's manual
a lso appears in the instru­
ment cluster d isp lay and a warning tone
sounds .
The brake system will still respond even
without the assistance of the ABS system.
See your authorized Audi dealer as soon as
possible to restore full braking performance.

Malfunction in the brake system
If the brake warning light<=> page 14 and the
ABS warning illum inate
together there may be
a malfunction in the ABS, and there may also
be a malfunction in the brake system itself
<=>
&. . The ABS will not work and you will no­
tice a change in braking response and per·
formance .
In the event of a malfunction in the brake
system
the warning/indicator light _
(USA models)/ . (Canada models) in the in­
strument cluster flashes <=>

Malfunction in the electronic differential
lock (EDL)
T he EDL works t ogether w ith the ABS. The
ABS warning light will come on if there is a

190 Intelligent technology
ESP includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
f erential lock ( ED L) and e lectronic interax le
d ifferential lock* . ESP is switched on all the
time . In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
I!] c:;, page 191 , fig. 164 . Be sure
to switch ASR on again whe n you no longe r
need less tra ct ion.
Anti-lock braking system (ABS )
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even du ring hard b rak ing . Apply steady p res­
sure to the brake pedal. Do no t pu mp the ped­
a l. A puls ing in the b ra ke ped al ind icates that
the system is he lp ing you to b rake the vehicle .
Brake assist system
The brake assist system can decrease brak ing
d ista nce. It increases braking power w hen the
d river p resses the brake pedal quic kly in eme r­
gen cy situa tions. You mus t press and hold the
b rake peda l until the si tuation is over. In veh i­
cles with adaptive cruise control*, the brake
assist system is more sensitive if the distance
detected to the vehicle ahead is too smal l.
Anti-slip r egulation (ASR)
ASR reduces engine power when the d rive
wheels begin to spin and adapts the fo rce 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 power to the o ther d rive
wheel or whee ls i f th e vehi cle is equipped with
a ll-whee l drive *. This function is available up
to about 7S mph (120 km/h).
I n extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Electronic interaxle differential lock */
selective wheel torque control*
The electronic interaxle differential lock (front
whee l drive) or the se lective whee l torque
control (all-wheel dr ive) operates when d riv­
ing t hrough curves . The front wheel on the in­
s ide of the curve or both whee ls on the inside
of the curve a re b raked select ively as needed .
T his m inimizes sliding in th e front wheels and
allows for mo re p reci se d rivi ng throug h
c ur ves . The appl icable system may not acti­
vate when dr iving in we t or snowy conditions.
_& WARNING ~
- ESP , ABS, AS R, E DL and the e lectronic in­
terax le d iffe rential lock function* cannot
overcome the laws of physics . This is es­
pecially important on slippery or wet
roads. If the systems begin acti ng to sta­
b ili ze your ve hicle , you s hould immed i­
ately c hange yo ur speed to match the
road and traffic cond itions. Do not let
t he incre ased safety provide d by the se
systems tempt you to take risks. Do ing
so will increase the r is k of a loss of vehi­
cle control, collision and serious persona l
in jur ies.
-Always adapt your speed to road, traffic and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and o n slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESP, ABS, the brake ass ist system,
E DL, ASR and the e lectronic interax le dif­
fe ren tial lo ck fu nction * can not prevent
coll is ions.
- Always ac celerate with spe cial care on
even, smooth s urfaces such as tho se th at
ar e we t or covered with i ce and snow.
The drive wheels can spin eve n with
these assistance systems t hat cannot al­
ways he lp to red uce the risk of loss of ve -
hicle control. ..,.
