switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres
sure to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe
ty provided by these systems tempt you
Intelligent technology 145
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
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 driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys
tem, EDL and ASR cannot prevent colli
sions.
- 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 al
ways he lp to reduce the risk of loss of ve
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.

Braking
General information
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
brake pads do not possess their full braking
effect, they have to be "broken in" first. The
distance can be ten times longer in vehicles
with ceramic brakes*. You can compensate for
th is slightly reduced braking 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 automobiles are still
subject to wear, depending largely on operat
ing condit ions and driving habits ¢.&, . On
vehicles that are either driven mostly in stop
and-go city traffic or are driven hard, the
brake pads should be checked by your author
ized Audi dea ler more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
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 cont inuously. Pump the brakes at inter
vals.
Moisture o r road salt
Under certain conditions, for example, when
driving 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 applications 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 discs in regular inter
vals so as to improve reaction time when brak
i ng 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,
you clean
off accumulated salt coating from
brake discs and pads with a few ca utious ap
plications of the brake<=>,& .
Co rrosion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firmly a few times from a moderately high
speed<=> ,&.
Fa ult s in th e bra ke s yste m
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed. Drive immed iately to
the nearest qualified workshop to have the
damage repa ired. Drive at reduced speed on
the way there and anticipate longer stopping
d istances and higher peda l pressure¢ _&.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake flu id level is too low . The brake fluid
l eve l is monito red electronically .

_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Other road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by resting you r
foot on the pedal when you do not intend to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain cl imatic and operat ing
conditions such as passing through wa
ter, dr iv ing in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
discs and drum s. Carefully app ly bra ke s
for a test. Brakes w ill dry and ice coa t
ings w ill be cleaned
off after a few care
fu l brake applications.
- Driving for an extended period of time on
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
Clean
off accum ulated salt coating from
brake discs and pads with a few cautious
brake applications.
- I f 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 the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in
creased stopping distance. Avoid driving
the vehicle a nd have it towed to the near
est A udi dealer or qualified workshop .
- Never let the veh icle roll to a s top with
the engine shut
off. .,.

(D Tips
Clean the spoiler compartment every 2 to
3 months. The spoiler compa rtment must
always be free of ice, snow, leaves or other
debris.
Power steering
When the engine is running, power steering
makes it easier for the driver to steer.
Power steering he lps the driver steer the vehi
cle with little physical effort .
If the engine is not runn ing, the power steer
ing system is also not wo rking. In this case,
you will find it extreme ly difficult to turn the
steering whee l.
If you t urn t he steering fully to the le ft or
right when the vehicle is stationary, you place
a very heavy load on t he power steering sys
tem . T urning the steering wheel fu lly to the
left or r ight will cause noise in the system . It
a lso reduces engine idle speed.
(D Note
Do not hold the steering turned fully to
the left or right for more than 10 seconds
when t he engine is running. There is a risk
of damage to the power steeri ng system .
@ Tips
-In the event of a power steering system
failure, or if the eng ine is not running
(while being towed), you wi ll st ill be able
to stee r the ve hicle . However, you will re
quire more effort to do so .
- If the power steer ing system has a leak
or is defective, you should immed iately
contact a qualif ied wo rkshop.
- The powe r stee ring system requires a
spec ial hyd raulic f luid. The powe r stee r

Dry sump Lubrication
H igh lateral and long itud inal forces affect the
engine and the vehicle d uring sporty driving.
Ory sump lubr ication ensures that your eng ine
Int ellig ent technolog y 149
is supplied wi th oi l and properly lubricated
even under these conditions .
In a "no rma l" veh icle the o il pump sends the
o il from the o il p an t o the lubr ication points in
t h e engine. The oi l then ret urns to the o il pan .
In extreme situations , the oil p ump may draw
in a ir, which results in insufficient oi l pressure.
Wi th dr y sump lubri cat ion, the o il is not in the
oi l pan (it is "dry"), but in a separate oil tank.
While one p ump supplies t he e ngine with oil ,
a second pump suctions the oil out of the en
gine and returns it to the oil tank. Because the
o il tank is tall and narrow, oil pressure is con
stant even under extreme conditions .
In add ition, the oi l pan in vehicles with dry

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
tery is discharged by idling current consumers
(e .g. immobilize r). In certa in circumstances it
can resu lt in the re be ing insufficient energy
available to start the engine.
Intelligent energy management in your vehi
cl e ha ndles the distribution of e lectr ica l ene r
gy . Start ing ability is ma rkedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b att ery diagn osis, idlin g current manage
m ent
and dynamic en erg y manag em ent .
Battery di agnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery cu rrent and battery
tempe rature. This determines the current
state o f charge and the power of t he battery .
Idling current m anagem ent
Idling current management reduces energy
consumption while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supply to the various electri ca l compo
nents. Da ta from ba ttery diagnos is is cons id
ered.
Depend ing on the batte ry's state of cha rge,
individual cons ume rs a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energy manag ement
While the vehicle is being d riven, dynamic en
ergy ma nagement distr ibutes the energy gen
era ted a ccord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
t h at more electrical energy is not being used ..,.
than is being generated and ensures an optimal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
limited.
- If starting ability is threatened, you are
i nformed by a warning
¢ page 151,
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
driving, in city traffic and during the co ld time
of year. Abundant e lectrical energy is re
quired, but only a litt le is generated. It is also
cr itical if the engine is not runn ing and electri
cal components are turned on. In th is in
stance energy is being consumed but none is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat
in g the distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains sta rting capab ility over a longer per iod.
Take into consideration that when you unlock
your veh icle, some convenience functions,
such as the remote key or power seat adjust
ment, may not be available . The convenience
functions will be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis
charged .
Intellig ent technolog y 151
If starting capability is jeopardized d ue to en
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although electrical energy is generated when
the ve hicl e is being driven, t he battery can be
come disc harged. This happens mostly when
li ttle energy is being generated and a great
deal consumed and the battery's state of
c h arge is not optimal.
T o b ring the energy ba lance back into equili
br ium, consumers which requ ire espec ially
large amounts of energy are temporari ly cut
back or switched off . Heating systems in pa r
ticu lar require a great deal of energy. If you
notice, for example, that the heated seats* 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 ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . Th is is normal and not
a cause for concern . By increas ing engi ne idle
speed the additional energy required is gene r
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his not ificat ion reminds yo u that the start ing
capability of the engine may be limited . As
soon as you sta rt driving again, the battery
will be recharged and the not ificat ion w ill go
out. •

Driving and
environment
Break-in period
A new vehicle must be broken in, and the
break-in period should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 m iles (1,000 km) and do not exceed the
maximum engine speed of 6,000 rpm You
must also not use full accelerat ion between
600 and 1,200 mi les (1,000 to 2,000 km).
Fr om 1,200 to 1,500 miles (2,000 to 2,500
km), you can gradua lly increase maximum en
gine speed to 8,250 rpm for brief periods.
During the first hours of operation, there is
greater friction in the engine and the trans
mission than later when all the moving parts
have broken in.
The way you drive during the first 1,500 miles
(2,500 km) affects engine quality. If you drive
at moderate eng ine speeds thereafter, partic
ularly when the engine is cold, you 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 automatically.
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaus t
system parts do not bottom out and get dam
aged.
This is especially true for vehicles with low
slung chassis (sports chassis) and fully loaded
veh icles.
Driving and environment 153
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through 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 walking speed .
A WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re
store the full braking effect.
(D Note
Vehicle components such as the eng ine,
transmission, suspension or electrical sys
tem can be severe ly damaged by dr iv ing
th rough water.
(D 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 ra ise 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 corrosion.

It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in on environmentally sound manner .
