Using steering angle and vehicle speed, the direction the driver
wishes to travel is determ ined and continuously compared with
actual vehicle behavior . If the two do not match, for example when
the vehicle begins to skid, ESP brakes the appropriate whee l auto-
matically .
The vehicle is stabilized again by the forces acting on the whee l
dur ing braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, w ith an understeering vehicle
(tendency to run wide in the curve) at the rear wheel on the inside of
the curve or additionally at the other wheels as needed . This brake
application is accompanied by noises .
ESP works in conjunction with ABS => page 175 . If there is malfunc-
tion in the ABS, ESP is also inoperat ive.
Activating
The ESP is automat ically activated when the eng ine is started, and it
performs a self -test. As soon as the test is comp leted, the system is
in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated,
pressing the button => page 170, fig. 129 returns the
system to normal operation .
Deactivating
ESP should normally be activated at all t imes because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Ant i-Slip Regulation (ASR) or the Electronic
Stabi lity Program (ESP) by pressing the button => page 170, fig. 129.
Both deactivation stages can only be activated from normal mode .
Deactivating
ASR
Tap the switch . Deactivation is indicated by s low flashing of the ESP
lamp in the instrument cluster. In certain situations (e.g. driving with
snow ch ains, in deep snow or on loose ground, or when rocking the
car free), it may be necessary to deact ivate ASR. ASR is active above
about 45 mph (70 km/h) and deactivated auto matically below this
speed.

Vehicle operation
Deactivating
ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the instrument
cluster staying on permanent ly.
This deactivates the Electronic Stability Program (ESP) in add ition to
ASR. No Electronic Stability System operat ion and no Anti-Slip Regu-
lation is available across the entire speed range; ASR and ESP are acti-
vated only when the brakes are used for the durat ion of the braking
action and remain active until a stable vehicle condition has been
reached. There is no dr iving situat ion wh ich requires ESP to be deac-
tivated, so this should only be done if the driver's skill and the traffic
situation pe rm it .

WARNING
•
The limits of physics cannot be suspended by ESP. Even in vehi-
cles with ESP, you should always adapt your driving to road and
traffic conditions . This is parti cularly true on a slippery and wet
road. Do not be tempted by the increased safety provided to take
risks - danger of an accident!
•
Please note that when ASR or ESP/ ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can break
away· danger of skidding!

Tips
In the event of a defect in the rear spoiler system or in Audi magnetic
ride, it can happen t hat ASR and ASR/ESP cannot be deactivated,
or
they are act ivated automatically
in the deactivated state . •
