lead to greater tire wear and will affect driving
behav ior.
Do not drive on
winter tires year-round , as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book ­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
Driving
valves , which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,

your foot on the accelerator pedal prevents
the cruise control from braking. This is be­ cause pressing the accelerator pedal over­
rides the cruise control system .
-If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is sw itched on, the braking function in
the system may be switched off. The rest of
the cruise control system f unctions remain
a ct ive as long as the

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

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) .

\.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

- 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
