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 the veh icle oversteering and un­
dersteering or the wheels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
ing engine torque. When ESC engages, the
G1 i n­
d icator light blinks in the inst rument cluste r.
The fo llow ing systems are integrated in the ESC:
Anti -lock b raking system (ABS)
ABS prevents the whee ls from loc king when brak­
i n g . The vehicle can sti ll be steered even d uring
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assi st sy stem
The brake assist system can dec rease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situat io n is over .
Anti- s lip regulation (ASR )
ASR reduces eng ine power when the drive w heels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and dr ive up h ills .
Electron ic differential lock (EDL)
The ED L bra kes wheels that a re spinning and
transfers the drive power to the other drive
wheel or wheels if the ve hicle is equipped with a ll
wheel drive*) . This funct ion is not ava ilable at
h igher speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over­ heating. The vehicle is still work ing correctly. EDL
92
will switch on again au tomatically when condi ­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze the vehicle by cha ng ing
t h e s teer ing torque .
Selective wheel torque control
Selective wheel to rque cont rol is used when d riv­
i ng o n curves . The front whee l on the inside of
t h e curve or both wheels on the i nside of th e
cu rve are braked se lective ly as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "automat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc ident. If the a irbag
c ontro l modu le detects a collision above a cert ain
vehicle speed, the veh icle is braked by the ESC.
The veh icle does n ot brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. This is es pec ially impo rtan t
on sl ippery or wet roads. If the systems be­
gi n a cting to stabili ze yo ur vehicle, you
s hould immedi ately alte r your speed to
match the road and tra ffic conditions . Do
not let t he in creased safety provi ded tempt
you into taking risks . This could increase
your r is k of a coll is ion.
- Please note the r is k of a coll is ion increases
when dr iv ing fast, especially th rough c urves
and on slippery or wet roa ds, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
ve nt co llisions - there is st ill a risk of acci­
dents!

Intelligent Technology
_&. WARNING
You should only switch offroad mode on or
switch ESC/ ASR off if your driving abilities
and the traff ic conditions perm it. There is a
r isk of slid ing.
- The stabilization function is limited when
offroad mode is switched on. The driving
wheels co uld spin and the vehicle could
swerve , especially on slick or slippery road
surfaces.
- T here is no vehicle stab ilizat ion when ESC/
ASR are switched off .
Hill descent assist
Applies to: vehicles with hill hold assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig . 100 Center console: hill descent assist button
.,. To switch the hill descent assist on, press the
~ button in the center console c:> fig. 100. The
LED in the button turns on.
.,. Press the button again to switch it off. The LED
in the button turns off.
Hill descent assist brakes all four wheels auto­
matically in order to limit speed when driving ei­
ther forward or reverse on hills with a grade up to
approx imately 50%.
When hill descent assist is on, the speed your ve­ hicle was traveling when it entered the hill is
maintained. It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist occurs br iefly after start ing to drive
up to approximately 19 mph (30 km/h). The driv­
er can increase or decrease the vehicle speed
94
within these limits by pressing the accelerator or
brake peda l.
However, there must be enough tract ion. Hill de­
scent assist
cannot function as expec ted, if fo r
example the hill is icy or if the surface is loose
c:>,& .
Active assistance at a specific speed up to about
19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h). The system is
then in ready-mode . This is indicated by the LED
i n the button turning on. The system automat i­
ca lly switched off when you drive faster than 37
mph (60 km/h) . The LED will also turn off in this
scenario.
Hill descent assist is automatically activated un­
der the following conditions:
- the LED in the button turns on,
- the vehicle speed is lower than 19 mph (30 km/
h),
- the incline angle is at least around 10%.
_&. WARNING
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident .
-
-The hill descent ass ist system cannot over­
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- Hill descent ass ist may not be ab le to hold
your vehicle at a constant speed under all
conditions while dr iv ing on a hill (for exam­
ple if ground u nder the vehicle is loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" first. However, you can ..,.

compensate for the slightly reduced bra king
force by pressing firmly on the brake peda l. Avoid
heavy braking during the break -in period .
Operating condit ion s and dr iving habits
The brakes on today's automobiles a re sti ll s ub­
ject to wear, depend ing largely on ope rating con­
ditions and driving habits¢& . On vehicles that
are either driven most ly in stop-and -go city traf ­
fic or are driven hard, the brake pads should be
checked by your authorized Aud i dealer more of­
ten than specified in the
Warran ty & Mainte ­
n anc e boo kle t .
Failure to have your brake pads
inspected can resu lt in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the eng ine. This way, you prevent unnec­
essary wear on the brake system . If you must use
your brakes, do not hold the b rakes down cont in­
uously. P ump t he b rakes at intervals.
Operating no ise
Noises may occur when braking depend ing on the
speed, braking force and outs ide cond itions such
as tempe rature and humidity .
Effect of water or road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight con­
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
"dr ied" fi rst w it h a few careful brake applica­
tions .
At highe r speeds and with the windsh ield w ipers
turned on, the brake pads press aga inst the brake
rotors for a short amount of time. This action,
which is not felt by the d river, happens a t regular
i nte rvals and ens ures a better reaction time fo r
the brakes in wet weather.
The bra king effect can also be redu ced if you are
d riving on salted roads and you do not apply t he
b ra kes fo r long pe riods of time. The layer of sa lt
on the brake rotors and brake pads m ust be worn
off first when the b rakes are applied¢& .
Intellig ent Technology
Corrosion
Leaving t he vehicle pa rked fo r lo ng periods of
t ime, low mileage and avoiding heavy braking
can contrib ute to corrosion on the brake rotors
and to dirty brake pads .
If you usua lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢& .
Brake system malfunction
if you no tice that the b rake peda l t ravel has sud ­
denly
gotten larger, then a b rake c ircuit may have
f ailed ¢ & .
Low brake fluid level
When the brake fluid level is low, malfu nctions in
the b rake system may occur. The b rake fl uid level
is e lec tron ically moni tored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
It only works when the en­
gine is running~ &.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
t h rough the openings in the wheel. If necessary,
the wheel may be removed for this i nspection
¢ page 198, Replacing wheels .
,&. WARNING
-New brake pads don't have the bes t stop­
ping power and m ust be "broken-in" during
the initial 250 mi (400 km) . You
can com ­
pensate for this by pressing the brake pedal
more firmly . This a lso applies later when
new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road condit ions permit. Other road
users must not be put at r isk - you may
cause an accident!
- Before descending a steep grade, reduce
speed a nd sh ift transmission into a lower
95

Intelligent Technology
gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the brakes to get hot and diminish braking efficiency .
- Do not "ride the brakes" by resting your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over ­
heat, premature wear and increased stop­
ping distance.
- Under certain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after washing the vehicle ,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications .
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assistance.

passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 1 SO lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
184
driver's side B-pillar ¢ page 181,
fig. 149.
~ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and
increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­ tal load being transported -including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Care and cleaning
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
- To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight. -
To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spec ially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
