A WARNING
-
If there is a malfunction, the indicator
light for the electro-mechan ical power as­
sist illum inates. Seek profess ional assis­
tance .
f;.!C; Electronic stabilization program
(ESP )
If the J$.] indicato r lamp blinks while dr iving,
the ESP or ASR (Anti-S lip Regulation) is active ­
ly regulating .
I f the
J$.] indicato r lamp ill uminates , the sys­
tem has switched the ESP
off. In this case, you
can switch the ignition
off and then on to
switch the ESP on again. The system is func­
tioning comp letely when the indicator lamp
switches
off.
If the I indicator lamp illuminates, the ESP
was switched
off with the I!] button.
St abili sation pr ogra m and ABS : fa u lt! Se e
o w ner's manu al
If the DJ indicator lamp and the [I] ABS indi­
cator lamp illumi nate and the dr iver message
appears, the ABS or e lectronic differential lock
is ma lfunctioning . This also interrupts the
ESP. The brakes sti ll function with their nor­
mal power, but ABS is not active.
Drive to yo ur authorized Aud i dealer immedi­
ate ly to have the mal function cor rected .

ABS/ <0 Anti-lock brake system
This warning/indicator light monitors the ABS
and the electronic differential lock (EDL).
The warning/indicator light m (USA mod­
e ls)
;ti] (Canada models) will come on for a
few seconds when the ignition is switched on .
The light will go out afte r an automat ic check
seq uen ce is completed.
Ther e is a malfunct ion in the ABS when:
- The warning/indicator l igh t does no t illum i­
nate when you switch the ignition on.
- The warning/indicator ligh t does not go out
after a few se conds .
- The warning/ indicato r light illum inates
while driving.
The ESP ind icator light also illum inates if
there is a ma lfunction in the ABS. The mes­

Malfunct ion in the brake system
If t he brake war ning ligh t¢ page 15 and the

together there may be
a malfunction in the ABS , and there may also
be a malfunction in the brake system itself

162 Intelligent technology
ESP includes and/or works together with the
anti-lock brake system (ABS), brake assist sys­
tem and anti-slip regulation (ASR). ESP is
switched on all the time. In certain situations
when you need less tract ion, you ca n sw itch
off ESP by pressing the button [g] _ Be sure to
switch ESP on again when you no longer need l ess traction .
Anti-lock b raking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the b rake pedal ind icates that
the system is he lp ing you to b ra ke the vehicle.
Br ake a ssist system
The brake assist system can decrease braking
d istance. It increases braking power when the
d river presses the brake pedal quick ly in eme r­
gency situations. You must press and hold the
brake peda l until the si tuation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road co ndit io ns. This makes it easier to
start, ac celerate and drive up hills.
Electronic differential loc k (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
a ll-wheel d rive*. This funct ion is available up
to abo ut 60 mph (100 km/h).
In extreme cases, EDL automat ically switches
off to help keep the brake on the braked whee l
from ove rheating . EDL w il l switch on aga in au­
tomatically when conditions have returned to
n o rmal.
& WARNING
- ESP, A BS, ASR an d EDL cannot ove rcome
the laws of physics . This is espec ially im ­
portant on slippery or wet roads. If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately cha nge your speed to matc
h the road and t raffic
conditions. Do not let the increased safe­
ty provided by these systems tempt you
to take risks. Do ing so w ill increase the
ris k of a loss of veh icle control , co llision
and serious pe rsonal inj uries .
- Always adapt your speed to road, traffic and weather conditions. The risk of los­
ing control of the vehicle inc reases when
d riving too fast, espec ially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESP, ABS, the brake assist system, EDL an d ASR cannot prevent collisions.
- Always accelera te with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR only work correct ly when
all four wheels are equipped with identi­
cal tires. Diffe rent tire sizes can lead to a
reduction in engine powe r.
- You may hear noises when the systems
descr ibed are working .
- If the indicator light
D] or m (USA
mode ls)/ KC] (Canada models) appears,
t here may be a malfunction~
