t he EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.

A WARNING
- Even ESC, ABS, EDS and AS R cannot over
come the laws of physics . You should
keep t his in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld ad just your speed immediate
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro
vided to take risks -you risk having an
accide nt.
- Please keep in mind that the risk of an
accident is i ncreased by d riving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve
hicle ahead . Even ESC, ABS, E DS and A SR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel
erating on a consistently s lippery sur
face, e .g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accide nt.
- Please note that when ASR or ESC/ASR is
deactivated , the drive wheels can spin on
icy and sl ippery roads a nd the veh icle can
break away -the re is a risk of skidd ing!

Braking
New brake pads
During the first 250 miles (400 km), new
b rake pads do not possess their full braking
effect, they have to be "broken in" first. The
distance can be ten times longer in veh icles
with ceramic brakes*. You can compensate for
this slightly reduced brak ing power by push
ing harder on the brake pedal. Avoid heavy
braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat
ing conditions and dr iv ing habits
c:> & . On ve
hicles that are either driven mostly in stop
and-go city traffic or a re driven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the
Warranty & Maintenan ce booklet . Failure
to have your b rake pads inspected can result
in reduced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you prevent un
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter
va ls.
Moisture or road salt
Under ce rta in conditions, for example, when
d riving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few cautious brake applicat ions should dry
off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake d iscs in regular inter
vals so as to improve reaction t ime when brak
ing on wet surfaces. You, the driver, will not
notice anything.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likewise,
Intelligent technology 145
you clean off accumulated salt coating from
brake discs and pads with a few cautious ap
plications of the brake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
on ly for short trips with litt le use of the
brakes.
If the brakes are not used frequently, o r if cor
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed
c:> & .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have fai led . Drive immediately to
the nearest qualified workshop to have the
damage repaired. Drive at reduced speed on
the way there and anticipate longer stopping
distances and higher pedal pressure c:> &,.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake power assist unit
T he brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only when the engine is run
ning.
Brake lining wear status
Brake lining wear may be checked by visual in
spection of t he condition of the brake pads
thro ugh the openings in the wheel. If neces
sary, the whee l may be removed for this in
spection

A WARNING
--You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.

146 Intellig ent technolog y
Other road users must not be put at risk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or ho ld the pedal down
too long or too often . This cou ld cause
the brakes to get hot and d iminish brak
ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Thi s may cause the b rakes to
overheat, premature wea r and inc reased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa
ter, driving in heavy ra in 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. Cautiously apply brakes
for a test . Brakes will dry and ice coat
ings w ill be cleaned off after a few cau
t ious brake applications .
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you
ins tall a different spoiler, be su re the air
flow to the front brakes is not obstruct
ed. Otherwise the brake system co uld
overheat red ucing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
braking capab ility, resulting in increased
stopp ing distance. Avoid driv ing the vehi
cle and have it towed to the nearest au
thorized Aud i dealer or qualified work
shop .
- Never let the vehicle roll to a stop w ith
the engine shut off .
- If the brake booster is not working, for
example when tow ing your vehicle, or
because the b rake booste r has somehow
been damaged, the brake pedal must be pressed considerably harder to make up
for the lack of booster assistance .
Power steering
When the engine is running, power steering
makes i t easier for the driver to s teer .
Power steering helps the driv er steer the vehi
cle with litt le physica l effort.
If the engine is not running, the power steer
ing system is also not working . In this case ,
you wi ll find it extremely d ifficu lt to turn the
steering wheel.
If you turn the steering fully to the left or
rig ht when the vehicle is stationary, you p lace
a very heavy load on the power steering sys
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine id le speed.
(D Note
Do not hold the steering t urned fu lly to
the left or r ight for more than 10 seconds
when the engine is running . There is a r isk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be ab le
to steer the vehicle. However, you will re
quire more effort to do so .
- If the powe r stee ring system has a leak
or is defect ive , you should immediately
contact a qualified wor kshop .
- The power steer ing system req uires a
special hydraulic fl uid. The power steer
ing fluid reservoir is located in t he en
gine comp artment. The co rrect hydrauli c
fluid level is important for proper opera
tion of the power steering system. The
power steering fluid level is checked ac
cording to the Audi maintenance service
schedule.

With all-wheel drive, all four wheels are driv
en .
Gene ral inform ation
W ith all-wheel dr ive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the t ime . See also <::;>
page 142.
Winter t ires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -sea
son t ires) for improved driveability and brak
ing: these tires must be mounted on
a ll f our
wheel s.
Snow chain s
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive

Replacing wheel s/tire s
Only the wheel/tire sizes specified by the

A WARNING
-Always adjust your driving to road and
traffic conditions. Do not let the extra
safety affo rded by a ll-wheel d rive tempt
you into taking extra risks .
- Although a ll-wheel drive is ve ry effect ive,
always remember that braking capacity
is limited by tire traction . You should
therefore 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

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat
te ry is d ischarged by idling current consumers
(e .g. immobi lizer). In certain circumstances it
can resu lt in the re being insufficient energy
available to start the engine.
Intelligent energy management in your vehi
cle handles the distribution of e lectr ica l ene r
gy. Starting ability is markedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b atte ry diag nosis, idling current m an age
m ent
and dy namic energ y manag ement .
Batte ry diagno sis
Battery diagnosis continuously determines
the state of the batte ry. Sensors determine
battery voltage, battery current and batte ry
temperature . This determines the current
state of charge and the power of the battery.
Idling current manag ement
Idling current management reduces energy
consumption while the vehicle is standing.
Wi th the ign ition switched off, it controls the
energy supply to the various electrica l compo
nents. Data from battery diagnosis is consid
ered.
Depend ing on the ba ttery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

Dynamic energy management
While th e veh icle is be ing dr iven , dynamic en
e rgy management distributes the energy gen
erated according to the needs of the individu
a l components . It reg ulates cons umption, so
that more electrical energy is not being used
t han is being generated and ensures an opti
mal state of charge for the battery .
(D Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, you are
i nformed by a warn ing
<=> page 148,
Driver notification in the instrument
cluster display .
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
d riving, in city traffic and duri ng the co ld time
of year. Abu ndant e lectr ica l energy is re
qu ired, but only a little is g ene rated . It is also
cr itica l if t he engine is not run ning and ele ct ri
cal componen ts ar e turned on. In th is in
stance energy is being consumed but none is
being generate d.
It is in precisely these si tua tions that you w ill
notice energy management actively regula t
ing the distrib ution o f energy .
Vehicle stands for an extended period
If you do not drive you r vehicle over a period
of severa l days or weeks, elect rical compo
n ents are grad ually cu t back o r swi tched off .
This redu ce s energy cons umption and mai n
tains s ta rting cap abili ty over a longer period .
T a ke into considerat ion tha t when you u nlock
your ve hicle, some co nvenience func tions,
such as the remote key or power sea t adj ust
men t, may not be available. The convenience
f u nctions will be avai lable again when you
turn on th e ignition and start the engine. With the engine turned off
If you
listen to the radio, for examp le, w it h

If starti ng capab il ity is jeopard ized d ue to en
ergy consu mptio n, a mess age a ppea rs in the

You have to start t he engine to charge the
ba tte ry.
With the engine running
Althoug h electrical energy is generated when
the vehicle is being d riven, the battery can be
come discharged. This happens mostly when
li ttle energy is being ge ne rated and a g reat
deal consumed a nd t he battery's state of

not ice, for examp le, that the heated seatsat or
the heated rear window are not heating, they have been temporarily cut back or switched
off . These systems w ill be available again as
soon as the e ne rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for concern. By increasing engine id le
speed the additional energy required is gener
ated and the battery is charged .
Driver notification in the instrument
cluster display
If bat tery power drops in to the range where i t
can limit the ability of the engi ne to start, this
is shown in the instrument cluster display
with the following driver message:
(•] Low battery charge: battery will be

will be recharged and the notification will go
out.
Driver notification appears and goes out
again
If this driver notification appears after the ig
nition is turned on or while driving and it goes
out again after a wh ile, the battery has been
adequately recharged.
Driver notification appears and does not
go out again
If this driver notification appears after the ig
nition is turned on or while driv ing and does
not go out again, the battery's state of charge
is not in the optimal range. Starting ability is
restricted. Have the battery checked as soon
as poss ible by an author ized Audi dealer or
qualified workshop.
Dry sump lubrication
H igh lateral and long itud inal forces affect the
engine and the vehicle during sporty driving.
Dr y sump l ubr ica tion ensures that your engine
i s supplied w ith oil and properly lub ricated
even under these conditions.
I n a "normal" veh icle the oi l pump sends the
oil from the oil pan to the lubrication points in
the engine. The oil then returns to the oil pan .
I n extreme situations, the oil pump may draw
in air, which results in insufficient oil pressure.
With dry sump lubrication, the oil is not in the
oil pan (it is "d ry"), but in a separate oi l tank.
While one pump supplies the engine with oi l,
a second pump suctions the oi l out of the en
g ine and returns it to the oil tank . Because the
oil tank is ta ll and narrow, o il pressure is con
stant even under extreme conditions.
In addition, the oil pan in vehicles with dry
sump lubrication is noticeably sha llower. Th is
allows the engine to be installed lower in the
vehicle, bringing down the center of gravity .
This improves your vehicle's handling .

Driving and
environment
Break-in period
A new vehicle must be broken in, and the break-in per iod should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 miles (1,000 km) and do not exceed the
maximum eng ine speed of 6,000 rpm You
m ust also not use fu ll acce lerat ion between
600 and 1,200 m iles ( 1,000 to 2,000 km).
Fr om 1,200 to 1 ,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en
gine speed to 8,250 rpm for brief periods.
During the first ho urs of operation, there is
g reater friction in the engine and the trans
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1 ,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic
u lar ly when the engine is cold, yo u reduce en
gine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low. Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov
erned automa tically.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body .
- Do not drive faster than wa lking speed .
.&_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re
sto re the full braking effect .
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys
tem can be severe ly damaged by dr iv ing
through water .
@ Tips
-Check the depth of the water before d riv
ing through it.
- Do not stop the vehicle, 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 vehi
cle to drive through safely .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i
cle, otherwise you will destroy the ca talyt ic
converter .
Never run the fuel tank completely dry; their
regular fue l supply could cause misfires . This
allows unburned fue l into the exhaus t system,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
a reas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con
