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 195
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. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . 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
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. 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 switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 197, fig. 182. Be su re to switch ASR
o n again when you no longer need less trac­
tion.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles wi th adap tive c rui se control*, the
brake assis t system is more sensitive if the

198 Intelligent technology
-Automatic retraction : When speed drops be­
l ow about SO mph (80 km/h), the rear spoil­
er retracts automatically.
Manual mode
- Manual deployment: Tappi ng briefly on the
switch
¢ fig. 183 dep loys the rear spoiler.
- Manua l retraction: At speeds up to about
10 mph (20 km/h), ret ract the rear spoiler
by pressing and holding the switch
¢fig. 183 . At speeds between 10 mph (20
km/h) and 80 mph (130 km/h), retract the
rear spoiler by tapping on the switch
¢fig . 183.
Indicator lights
1,1 /. Rear spoiler: system malfunction!
The rear spoiler may not have extended due to
a malfunction. This could change the vehicle's
driving characteristics at high speeds. Do not
exceed 85 mph (140 km/h). Drive to your au­
thorized Audi dealer immediate ly to have the
malfunction corrected . The co lor of the indica­
tor light depend s on the veh icle speed.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler deployed can impair handling char­
acteristics, making the veh icle harder to
control.
-Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (140 km/h). If th e rear spoiler
wa rning/ind icator light in the instru­
ment cluster comes on, the rear spoiler
may not have deployed.
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
dep loyed. Have the spoiler inspected as
soon as possible by an authorized A udi
dealer or qualified workshop.
- Always obey speed limits and other traf­
fic laws.
A WARNING
Improper operation of the rear spoiler can
cause crushing injuries. -
Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted.
(D Note
- Never push the vehicle or apply force to
the rear spoiler -it could be damaged.
- To prevent damage to the rear spoiler do
not lean or place anything on it .
- Only operate the rear spoiler man ually
when the rear lid is closed and the rear
spoiler moving parts are not blocked.
Otherw ise, damage co uld occur.
(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compartment must
always be free of ice, snow, leaves or other
debris.

General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving hab its
r:::;, ,& . On
vehicles that are either dr iven mostly in stop­
and-go city traff ic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes , you sho uld use the braking
effect o f the engine . This way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter­
vals.
Moisture or road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking .,..
