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. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in­
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi ­
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and dr ive up h ills.
Electronic differential lock (EDL)
E DL a ppl ies the bra kes to a wheel tha t st art s
sp inning and tra nsfe rs t he dr ive powe r to t he
120
other driving whee ls. This func tion is no t ava ila ­
ble at hig her speeds.
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r­
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a­
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat 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 iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not 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. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be­
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt

\.J - greater than the amount being generated in or­
der to maintain an optima l vehicle battery charge
l evel.
(D Tips
- Energy management cannot overcome the
laws of physics. Note that the charge level
and length of the vehicle batte ry life are
li mited.
- When the starting ability is endangered, the
(•j indicator light turns on ¢ page 14.
What you should know
Maintaining the starting ability is the highest
priority .
A lot of stress is placed on the vehicle battery
when driving short distances, during c ity driving,
and at co ld times of the year. A lot of energy is
used but little is generated. It is a lso critical
when the engine is not running but e lectr ica l
equ ipment is switched o n. In th is case, energy is
used but none is generated .
In s ituations like this, energy management will
actively regu late the distribution of ene rgy.
Long periods w ithout use
If yo u do not drive you r vehicle for several days or
weeks, e lectrica l equipment is gradually sca led
back or switched off. This reduces energy use and
ens ures the veh icle w ill be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances . These convenience functions will be
ava ilable again once you switch the ig nition on
an d s tart the engi ne.
With the engine switched off
T he vehicle battery will drain if yo u use I nfota in ­
ment f unctions such as listening to the rad io
while the eng ine is switched off .
The vehicle's ability to start may be impaired by
the energy use, a message will appear in the In ­
fotainment system d isplay .
The message ind icates that the system will
switch off automatically soon. If you wou ld like
Intellig ent Technology
to cont inue using the functions, you must start
t h e engine.
With the engine running
Alt hough e lectr ica l energy is ge nerated wh ile
dr iv ing , the ve hicle ba ttery can dra in. This ca n
happen if li ttle ene rgy is generate d but much is
u sed , and the charge level of the vehicle battery
is not optimal.
T o res to re the balance of ene rgy, componen ts
t h at require large amoun ts of ene rgy are tempo ­
rarily scaled back or switched off . Heat ing sys ­
tems in partic ula r req uire a great dea l of energy .
If you notice, for example, that the seat heating*
or rear window defogger is not work ing, then it
has been tempora rily reduced or sw itched off.
These systems are availab le aga in as soo n as the
energy sup ply has bee n restored .
In add ition, you may notice that the idle speed
has slig htly increased. That is normal and no
cause for concern . By increas ing the idling speed,
the addit ional required energy will be generated
and the vehicle battery will be charged .
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
Th is vehicle is equ ipped w ith an Event Data Re­
corder (EDR) . The ma in purpose of a n EDR is to
r ecord, in certai n cras h or nea r crash-like situa­
ti ons, s uch as an airbag deployme nt o r hi ttin g a
road obsta cle, da ta t hat w ill ass ist in underst and­
i ng how a vehicle 's systems performed . The EDR
is des igned to record data related to vehicle dy ­
namics and safety systems for a short perio d of
t ime, typ ica lly 30 seconds or less . The EDR in this
vehicle is designed to record such data as:
- How va rious systems in your vehicle were ope r­
ating;
- W het her o r not the drive r and passenge r safety
be lts were b uckled/fastened;
- How far (if at all) the driver was dep ressing the
accelerator and/or bra ke pedal; and, .,,.

-Me thanol f uels which do no t meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fail to meet the spec i­
fied criteria in this chapter .
- If you are unable to determine whether or not a particular fuel blend meets the spec i­
fications, ask your service station or its fuel supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control

- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
r ecommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . All gaso line grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIE R Detergent Gas­
oline. For more information on TOP TIER Deter ­
gent Gasoline, please go to the official website (www.toptiergas .com) .
192
After an extended period o f using inadequate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
([) Note
Damage or ma lf u nction due to poor fue l qual ­
ity is not covered by the Audi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles wi th diese l en gin e
Always use ULSD (Ultra Low Sulfur Diese l) No. 2 .
The ULSD No. 2 meets the ASTM D97S.
D iesel fuel w ith concentrations of b iod iesel high­
er than 5 % such as B l 1, B20 or BlOO are st rict ly
prohibited .
Se rvice station fuel pumps are labe led wi th the
correc t fu el i nfo rmation for easy recogn ition by
the user . If the diesel fue l pump is not labe led
ask the station operator what fue l is being dis­
pensed before filling up your vehicle .
U LSD No . 2 may no t be ava ilable outside the USA
and Canada . Be s ure to check befo re t raveling to
other countries .
U LSD No . 2 can become th ic k e r i n very co ld tem­
peratures, and this can impa ir the e ng ine's s tart­
i ng and running . Depend ing on the season, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper­
at ing your vehicle as usual.
(D Note
- Your vehicle's diese l engine was designed
so ley for use with ULSD No . 2 . Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.
- If you put any amo unt of incorrect fuel in
the fuel tank, do not start the engine under
any c ircumstances. Immed iate ly contact the
nearest author ized A udi dealer or author-
ized Aud i Serv ice Facility fo r ass istance .

\.J ' -Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as we ll as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
® For the sake of the environment
Even when the Emission Control System is op ­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states. This depends on the su lfur
content of the fuel being used. Using a differ­
ent brand of fue l may help, or filling the tank
w ith lead-free super grade gasoline .
Diesel particulate filter
Applies to: veh icles with diesel engine
The diesel particulate filter filters nearly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under normal driving
conditions . If the filter cannot clean itself (for ex­
ample , because you are only driving short distan­
ces), the fi lter becomes clogged with soot and
the

A WARNING
-Do not park your vehicle over flammable
materials such as grass or leaves because

the high temperature of the diesel particu­
late filter could start a fire.
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.

Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment, such as
checking and filling fluids, there is a risk of in­
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precaution s provided in the following in·
formation . The engine compartment is a dan­
gerous area on the vehicle.

- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
-Select the P selector lever position.
- Let the engine cool down.
- Never open the hood when there is steam or
coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping .
- Keep children away from the engine com­
partment .
- Never sp ill fluids on a hot engine. These flu­
ids (such as the freeze protection contained
in the coolant) can catch fire.
- Avoid short circuits in the electrical system.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
coo ling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.

Check ing and F illing
The coolant leve l is monitored through the. in­
dicator light ¢
page 14. However, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with d istilled water is recommended.
Coolant additiv e
The coolant addi tive is made of anti-freezi ng and
corros ion protection agents. Only use the fo llow­
ing coolant additives . These additives may be
mixed with each other.
