84 Transmi ssion
In the no rm al m ode D, the transmission auto­
matica lly selects the suitab le gear ratio. It de­
pends on eng ine load, veh icle speed and driv­
ing style.
Select the

The vehicle makes full use of the eng ine 's
power. Shifting may become noticeab le when
accelerating.
When the vehicle is stationary or at speeds
be low 1 mph (2 km/h), you must always apply
the foot brake before and while mov ing the
lever to D/S out of N.

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 situations, including
when the vehicle is beginning to spin (yaw) out of cont ro l and he lps you to get the vehicle
back under control by select ively b rak ing the
wheels, and/or red ucing engine power and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
DJ 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
help 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 water 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 171
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 the 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 173, fig. 166 or~ page 173,
fig. 167. Be sure to sw itch ASR on aga in when
you no lo nger need less traction.
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 with adaptive c ruise control*, the
brake assis t system is more sensitive if the
•
•

172 Intelligent technology
distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll switch on aga in a u­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC and its integrated sys­
tems cannot a lways p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
descr ibed are workin g.

Braking
What affects braking efficiency?
New brake pad s
Du ring the first 2 50 miles (400 k m), new
b ra ke pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
You can compensate for this slightly reduced br aking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
b reak-in per iod.
Operating conditions and d riving h abits
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat­
ing conditions and dr iv ing habits ¢.&. . On
vehicles that are e ithe r dr iven mostly in stop­
and-go city traffic o r are driven ha rd, the
b rake pads should be checked by you r aut hor­
iz ed A udi de aler more often than specified in
the
Warrant y & Maintenan ce booklet . Fail ure
to have your b ra ke pads inspected can resu lt
in red uced brake performance.
On steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the eng ine. Th is w ay, you preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
N oises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature a nd h umidity.
Due to the na ture of the mate rials used i n ce­
ramic brake rotors*, noises may become more
apparent at low speeds.
Effect of water and road salt
I n ce rtain situat ions, for exampl e after d riving
throug h wate r, in heavy ra in, after overn igh t
conde nsation or afte r washi ng your c ar, the
b ra ki ng effect can be reduced by moisture or
ice on the bra ke rotors and b rake pads. The brakes must be dr
ied first with a few careful
brake applications .
At highe r speeds and with the winds hield wip­
ers t urned on, the b ra ke pads press against
the b rake roto rs fo r a short amount o f time .
This occurs at regular intervals without the drive r not icing and p rov ides for better brake
response time under wet conditions.
The effectiveness of the brakes can be red uced
whe n the vehicle is driven on a sa lt -covered
road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap­
plicat ions of the bra ke
¢ .&. .
D ue to the ir s urface characteristics, ceramic
brake rotors* absorb moisture in such condi­
tions . T his can cause a temporary reduction in
braking force compared to dry brakes . You can
compensate for th is by pressi ng the brake
p eda l harde r.
Corrosion
There may be a tende ncy for dirt to build up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regu larly or
only for short trips w it h litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros io n has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed ¢.&. .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c::> .&. .
Low brake fluid level
Malfunctions can occur in the brake system if
t h e brake fluid level is too low. The brake flu id
level is monitored electro nically .
Brake boo ster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
on ly when the engine is running
. ¢ .&. .,.

c> page 244, Changing a wheel.
.&_ WARNING
- New brake pads do n't have the best sto p­
ping power and must be "broken-in" dur­
ing the init ial 100 to 1 50 m iles (150 to
200 k ilometers) of normal city driving.
T he break-in period can be considerably
longer for veh icles with ceram ic br ake ro­
tors*. You can compensate for this by pressing the brake pedal more firmly.
T his also applies later when new pads are
installed .
- You should perform braking maneuvers
for the purpose of cleaning the brake
system on ly if road condit ions permit.
Other road users must not be put at r isk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range. Do not ride
the brakes or hold the pedal down too
long or too ofte n. This cou ld cause the
brakes to get hot and d imin ish b raking
efficiency.
- Do not "r ide the brakes" by resting your
foot on the pedal when you do not inte nd
t o brake. Th is may cause the b rakes to
overheat, prema ture wear and inc reased
stopping distance .
- Under certa in climat ic and operating
conditions such as passing through wa ­
ter, driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­ ings will be cleaned off after a few ca re­
ful brake applications.
- Driv ing fo r an extended pe riod of time on
salt-covered roads w ithout using you r
Intellig ent technolog y 175
brakes can a lso affect braking efficiency .
Clean off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler , be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brake system could
overheat reducing t he effectiveness of
the entire brake system.
- Failure of one b rake circuit will impa ir
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle and have it towed to the near­
est a utho rized Audi dea le r or q ualified
workshop.
- Never let the vehi cle roll to a stop with
the engine shut off.
- If the b ra ke booste r is no t working, the
brake peda l must be p ressed considera­
b ly harder to make up for the lack of
booster assistance .
