Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
d ifficu lt driving situations, including when the ve­
hicle is beginn ing to spin (yaw) out of control and
helps you to get the vehicle back under control by
selectively braking the whee ls, and/or reducing
engine power and prov iding steer ing ass istance
to help hold the vehicle on the driver's intended
course. The indicator light
Bl in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations.
It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against. For example, ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of frict ion of the road surface . Whe n
there is a section of dry road that is suddenly cov­
ered with water, slush or snow, ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydroplanes (rides on a cushion of wa­
ter instead of the road surface), ESC will not be
ab le to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered . During fast
cornering, particularly on winding roads, ESC
cannot always deal as effectively with difficult
driving situations than at lower speeds. Whe n
tow ing a trailer, ESC is not able to help you regain
con trol as it wou ld if you were no t towing a trail­
er .
A lways adjust your speed and dr iving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
Smart Technology
available traction, or keep a vehicle on the road i f
road departure is a result of driver inattention.
Instead, ESC improves the possibility of keeping
the vehicle under control and on the road dur ing
extreme maneuvers by using the driver's steering
inputs to help keep the vehicle go ing in the in ­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can prov ide any assistance, you may not expe ri­
ence the benefits of ESC.
ESC is switched on all the time . In certain situa­
t ions when you need less traction, you can switch
off ASR by pressing the button
[ru ~ page 170,
fig. 152 or ~page 170, fig . 153. Be sure to
switch ASR on again when you no longer need
less traction.
T he following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when braking. The vehicle can still be steered even dur­
i ng hard braki ng. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is he lp­
ing you to brake the vehicle.
Brake assist system
The brake ass ist system can decrease braking dis­
tance . It increases braking power when the driver
presses the brake peda l quickly in emergency sit­
u at ions. You must press and hold the brake pedal
until t he situat ion is over. In vehicles with adap­
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
T he EDL brakes whee ls that are spinning and
transfers the drive power to the other wheels.
T his function is available up to about 60 mph
(100 km/h).
169

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .

nearest authorized Audi dealer or qualified repair
facility to have the malfunction corrected.
A WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler deployed can impa ir handling charac­
teristics, mak ing the veh icle harder to co ntrol.
- Always make sure that the spoiler is de-
ployed when driving at speeds over 85 mph
(140 km/h) . If the rear spoiler warn ing/ indi­
c ator light in t he instrument cluster comes
on, the rear spoi ler may not have deployed .
- Never dr ive at speeds highe r than 85 mph
(140 km/ h) if the spoiler is not deployed.
Have the spo iler inspected as soon as possi­
ble by an author ized Audi dealer or qualif ied
workshop.
- Always obey speed limi ts and o ther traffic
laws .

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking e ffect, they
have to be "broken in" first¢.&. . The break -in pe ­
riod can be considerably longe r for vehicles with
ceramic brake rotors*. You can compensate for
th is slightly reduced braking power by pushing
harder on the brake pedal. Avoid heavy braking
loads during the b reak-in period.
Op era ting condition s and dri ving h abit s
The brakes on today's automobiles are still sub­
j ect to wear, depending largely on operating con­
dit ions and driving habits ¢.&, . On vehicles that
are either dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by yo ur autho rized Aud i dealer more of­
ten than specified in the
Warranty & Mainte·
nan ce bookl et.
Fail ure to have you r brake pads
i nspected c an resu lt in red uced b rake pe rform ­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine. This way, you prevent unnec ­
essary wear on the bra ke system. If yo u must use
you r brakes, do not hold the brakes down contin ­
u ously. Pump the brakes at intervals .
Operating noise
Noises may occur when brakin g depending on the
speed, braking force and ou ts ide cond itions su ch
as tempera ture and hum idity.
Due to the nature of the materials used in ceram­
i c bra ke roto rs*, noises may become mo re appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water, in heavy rain, after overnight con­
densation or after washing your car , the braking
effect can be redu ced by moistu re or ice on the
1111>

brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications .
At h igher speeds and with the w indshield w ipers
turned on, the brake pads press against the brake rotors for a sho rt amount of time. This occurs at
regular intervals without the driver noticing and
prov ides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likew ise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢,&. .
Due to their surface characteristics, ceram ic
brake rotors* absorb moisture in such conditions.
This can cause a temporary reduction in braking
force compared to dry brakes . You can compen ­
sate for this by press ing the brake pedal harder .
Corrosion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to form on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed¢& .
Fa ul ts i n the brake sys te m
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed¢&.
Low brak e flu id l eve l
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
monitored e lectronically.
Brake boo ste r
The brake booster increases the pressure that you
genera te with the brake pedal.

Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 218, Replacing wheels .
A WARNING ...__
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the initial 250 miles (400 kilometers) . The
break-in per iod can be cons iderably longer
for vehi cles w ith ceramic b rake rotors*. You
can compensate for this by p ress ing the
b rake peda l more fi rmly. 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 conditions permit. Other road
users must not be put at risk -you may
cause an accident!
-
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving 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 dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing 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
p ing distance.
- Under certain cl imatic and operat ing condi­
tions such as passing t hrough water, dr iv ing
in heavy rain or after washing the veh icle,
the effect iveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fu lly 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 a lso affect braking efficiency.
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.

-If y ou dama ge the front spo iler, or if you in ­
sta ll a di fferent spoile r, be sure the air flow
to the front brakes is not obstructed . Other ­
wise the brake system co uld overheat reduc­

tem .
- Failure of one brake c ircuit will impair the
braking capab ility r esult ing in a n increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest au thorized
Audi de aler or qualified workshop.
- Never let the vehicle ro ll to a stop with the

Driving with your quattro
With all-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend­
i ng on your driving style and the road conditions
at the t ime . See also ~ page 169.

Winter tires
When driving in the w inter, your vehicle w ith all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount winter tires (or all-season tires) for
improved driveability and braking: these tires
must be mounted on
all four wheels. See also
c:> page 211, Winter tires .
Tire chains
Where tire chains are mandatory on certain
roads, th is normally also applies to vehicles with
all-wheel drive
c:> page 211, Snow chains.
Replacing wheels/tires
Vehicles w ith all-wheel drive must a lways have
tires of the same size . Also avoid tires with differ­
ent tread depths. For details see page
c:> page 203, New tires or wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible . Also refer to
c:>page 177.
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into tak ing
extra risks .
- Although the all-wheel drive is very effec­
tive, always remember that braking capac ity
is limited by tire traction. You should there­
fore not drive at excessive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be careful not to drive
too fast because the front wheels could be­
gin to slide on top of the water (aquaplan­
ing). If this should occur, you will have no
warning from a sudden increase in engine speed as with a front-whee l drive vehicle .
Always drive at speeds which are suited to
the road conditions -risk of crash .
Smart Technology
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa ­
bility of electrical energy for starting the engine.
If a vehicle with a conventional energy system is
not driven for a long period of time, the battery
is d ischarged by idling current consumers (e.g .
immobilizer). In certain circumstances it can re­
su lt in there being insufficient energy available to
sta rt the eng ine .
Intelligent energy management in your vehicle
hand les the distribution of electrical energy .
Starting ability is markedly improved and the life
of the battery is extended.
Basically, energy management consists of
bat­
tery diagnosis , idling current management
and
dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines the
state of the battery . Sensors determine battery
voltage, battery current and battery tempera­
ture . T his determines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumption while the vehicle is standing . With the
ignition switched off, it controls the energy sup­
ply to the various electrical components. Data
from battery d iagnosis is considered.
Depend ing on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre­
vent excessive discha rge of the batte ry and thus
mainta in starting capability.
Dynamic energy management
While the vehicle is being driven, dynamic energy
manageme nt distr ibutes the energy gene rated
accord ing to the needs of the individual compo­
nents.
It regu lates consumption, so that more
elect rical energy is not being used than is be ing
generated and ensures an optima l state of
charge for the battery. ..,.
175

Smart Technolog y
(D Tips
-But even energy management cannot neg­
ate the limits of physics. Consider that the power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•)appears
Qpage 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time of
year . Ab undant electrical energy is required, but
only a little is generated. It is also critical if the
engine is not runn ing and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situat ions that you wi ll no­
tice energy management actively regulating the
d istr ibut io n of energy.
Vehicle s tand s for an exte nded p eriod
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­
pability over a longer period. Some of the con­
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions will be ava ilable again
when you sw itch on the ign it io n and start the en­
g ine.
With th e engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI funct ions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­ p lay . The message ind icates that the system will
be sw itched off automat ica lly in a moment. If
you wish to cont inue using the functions , you
have to start the engine .
176 With the en
gine running
Although elec trical energy is generated when the
vehicle is being d riven, the battery can become
discharged . This happens mostly when litt le en­
ergy is being generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
T o bring the energy ba lance back into equilibri­
u m, consumers whic h req uire especially large
amounts of energy are temporari ly cut back or
switched off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* o r the heated rear
window are not heating, they have been tempo­
r ari ly cut back o r switched off . Th ese systems w ill
be ava ilable again as soon as the ene rgy ba lance
has been res tored.
You w ill also notice that engine id le speed has
been increased slightly . Thi s is normal and not a
ca use for concer n. By increasing eng ine idle
speed the addi tional energy required is gene rated
and the battery is charged.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first
350 miles (500 kilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water . ""
177

Driving and th e environment
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Warming up and cooling down
By carefully warming up and cooling down your
veh icle, you can help ensure that it is not over­
stressed unnecessar ily du ring sporty dr iv ing.
When warming up, the vehicle is driven at a max­ imum engine speed of 6000 RPM in order to ra ise
the engine oil temperature to a m inimum of
140 °F (60 °C). T he tires also only reach their full
road holding capab ility once they have wa rmed
up.
The cooling fan can continue to run in your vehi­
cle after the eng ine is switched
off. However,
d riving the vehicle to cool it dow n is part icu larly
important. During sporty d riving, the engine and
brakes , the exhaust system, and the transmission
all become extremely hot. Before you park the
vehicle, you should drive it for a few mi les/kilo ­
meters at light load in the low rpm range to al­
low it to cool down.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in on
environmentally sound manner .

Fuel supply.
.. Never ru n the tank down a ll the way to empty.

.. Never try to push -or tow-start your vehicle .
The catalytic converte r is an effi cient "clean-up"
device b uilt into the exha ust system of the veh i­
cle. The cata lytic conve rter burns many o f the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
The exclusive use of unleaded fue l is c ritically im ­
po rtant for the life of the catalytic conver ter and
proper functioning of the engine .
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. Th is could resu lt in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iving, the substance
used for unde rcoat ing could overheat and
cau se a fire.
@ Note
- Be aware that just one tank fill ing with lead­
ed
fuel w ill al ready ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
c::>poge 191.
-Do not drive until the fue l tank becomes
completely empty . T he engine cou ld m isfire .
Unburned fu el could also get into the ex­
haus t sys tem a nd this could cause the cata­
lyt ic converte r to overheat.
- Do not turn
off the ignition while the vehicle
is
moving.
- Do not continue to operate your veh icle un­
der these condi tions, as otherwise f uel can
re ach the cat aly tic converter. This could re ­
s u lt in ove rheat ing of the c onve rter, requ ir­
ing its replacement .
