Braking
What affects braking efficiency?
New brake pads
During the firs t 250 miles (40 0 km), new
b ra ke pads do not possess their f ull braking
effect, they have to be "broke n in" first ¢.&,. .
You can compensate for th is slightly reduced
brak ing power by push ing harder on the brake pedal. Avoid heavy brak
ing loads dur ing the
break -in period .
Operating conditions and driving habits
The bra kes o n today's a utomo biles a re still
s u bject to wear, depend ing largely on operat
ing condit ions and driving habits ¢.&,. . On
vehicles that are either driven m ost ly in stop
and-g o city traff ic or are dr iven hard, the
brake pads should b e chec ked by your au tho r
iz ed Audi dea ler mo re often than specified in
the
Warranty & Maintenance booklet . Failure
to h ave yo ur bra ke pads insp ect ed ca n result
in reduced brake pe rfo rmance .
On steep slop es, you sho uld use the b raking
effe ct o f the e ngine. This way, you prevent un
ne ce ss ary wear on the br ake sys tem.
If you
mus t use your brakes, do not hold the b ra kes
down cont in uou sly. Pump the brakes at inter
vals.
Operating noise
N ois es m ay o ccur when br akin g depend ing on
th e speed, brak ing fo rce and o uts ide condi

Effect of water and road salt
In certa in situa tions, for examp le afte r dr iv ing
t hr ough wa ter, in heavy rain, after overnight
c on den sat ion or after w ashin g your car , the
braking e ffec t ca n be reduce d by mois ture o r
ice on the b rake ro to rs and brake pads . The
brakes m ust be dr ied first with a few careful
brake ap plications .

184 Intelligent technology
At higher speeds and with the windshield wip
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet condit ions .
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 . Likew ise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap
plications of the brake¢&. .
Cor ro sion
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 l ittle 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
firm ly a few times from a moderately high
speed ¢,& .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢&. .
Low brake fluid le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically .
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal. It works
only when the eng ine is running .¢ &.
Brake lining w ear status
Brake lining wea r may be checked by vis ual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sary, the whee l may be removed for this in
spection
¢ page 244, Changing a wheel.
_& WARNING
-New brake pads don't have the best stop
ping power and must be "broken -in" dur
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving .
You can compensate for this by pressing the brake pedal more firmly . T his also
applies later when new pads are instal led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road users 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 or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa
ter, dr iving in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
d iscs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat
ings will be cleaned
off after a few care
fu l brake applicat ions .
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can a lso affect braking efficiency .
Clean
off accumulated salt coating from
b rake discs and pads wi th a few ca reful
b rake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
flow to the front brakes is not obstruct-
ed . Otherwise the brake system could

- Failure of one brake circuit will impair
the bra king capability resulting in an in
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near est author ized Audi dealer or qualified
wor kshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not work ing, the
brake pedal must be pressed considera

and on snow and ice . Always read and follow
safety precautions
c:> ,&. .
Winter t ires
When driving in the winte r, your ve hic le with
a ll-whee l drive has an advantage, even with
regular t ires. In winter road conditions it may
be adv isable to mount winter tires (or all-sea
son t ires) for improved dr iveability a nd brak

all four
wheels . See also i=>page 237, Winter tires.
Tire chain s
Where tire cha ins are mandatory on certain
roads, th is normally a lso applies to vehicles
with a ll-wheel drive

Replacing wheels /ti res
Vehicles w ith all -wheel drive must a lways
have tires o f the same size. Also avoid t ires
with d iffe rent tread depths . For details see
page
c:;> page 2 33, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does not have enough ground clear
ance to be used as an off-road veh icle.
It is
therefore best to avoid rough t racks and un
even terrain as much as possible . Also refe r to

ca pacity is limited by t ire traction . Yo u
sho uld the refore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road s urfaces, be careful not to
dr ive too fast because the front wheels co

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 wi th a conventiona l ener gy sys tem
is not driven for a long per io d of time, the bat
te ry is discharged by idling current consumers
(e .g. immobilize r). In certain circumstances it
can res ult in there being insufficient energy
available to start the eng ine .
Intelligent energy management in your vehi
cle hand les the dist ribution o f electr ica l ener
gy. Start ing ability is markedly improved and
t h e life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis contin uously de termines
t h e state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature. This determines the current
state of charge and t he power of t he battery .
Idling current management
Idling current management reduces energy
consumption while t he vehi cle is standing.
With the ign ition sw itched off, it controls the
energy supply to the various electrica l compo
nen ts. Data from battery diagnos is is cons id
ered .
Depend ing on the battery's state of charge,
individ ual consumers are gradually turned off ..,.
Page 189 of 286

to prevent excessive discha rge of the battery
and thus maintain starting capability .
Dynam ic energy man agement
W hile the vehicle is being driven , dynamic en
e rgy management distributes the energy gen
erated according to the needs of the individu
a l components . It regu lates consumption, so
that more electrical energy is not being used
than 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
limited.
- If starting ab ility is threatened, the indi
cator light (•) appears
¢ page 17.
What you should know
The highest priority is given to maintaining
starting capabili ty.
The battery is severely taxed in short-distance
driving, in city traffic and d uring the co ld time
of year. Abundant electrical energy is re
qu ired, but only a little is generated. It is also
cr itical if the engine is not run ning and electri
cal components are turned on . In th is in
stance energy is being consumed but none is
be ing generated.
It is in precisely these situations that you w ill
notice energy management actively regulat
i ng 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 o r switched off .
This reduces energy consumption and main
tains starting capab ility over a longer per iod .
Some of the conven ience fun ctions may not
ope rate, such as the in ter ior lig hts o r th e
power seat adj ustment. The conven ience
functions will be available again when you
switch on the ignitio n and start the engine .
Intellig ent technolog y 187
With the eng ine turned off
If you listen to the radio, for examp le, w ith
the engine turned off or use other MMI func
tions, the battery is being discharged .
If starting capab il ity is jeopardized d ue to en
ergy consump tion, the following warning ap
pears in the MM I display:
Pl ea se start the en gin e s oon or the sy ste m
will be turn ed off .
The warning indicates that the system w ill be
turned off automatically after 3 minutes . If
you w ish to continue using the funct io ns, yo u
have to sta rt the eng ine .
With the engine running
Although electrical energy is generated when
the vehicle is being driven, the battery can be
come d ischa rged . This happe ns mostly when
li ttle energy is being gene rated and a g reat
deal consumed and t he battery's state of
charge is not opt imal.
To b ring the energy ba lance back into equili
brium , consume rs which requ ire espec ially
la rge amounts of ene rgy are temporar ily cu t
ba ck or sw itched o ff. Hea ting systems in p ar
ticu lar require a great deal of energy . If yo u
notice, for examp le, 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 wi ll 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 gene r
ated and the battery is charged .

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive 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
max imum pe rm iss ible road or eng ine speed .
During and after break-in period
... Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutra l) or in gear.
After the break- in period
... Do not exceed max imum engine speed un
der any circumstances .
... Upshift into the next higher gear before
reaching the red area at the end of the tach
ometer scale¢ page 10.
During the first few hours of driving, the en
g ine's inter na l friction is higher than later
when all the moving parts have been broken
i n. How well this break- in process is done de
pends to a conside rable extent on the way the
ve hicl e is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto
mat ica lly r educ ed. However, t hese rpm
lim its are programme d for a n engine well

{® For the sake of the environment
Do not d rive with unnecessarily high en
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ
ment.
, New tires
If your vehicle is runni ng on new tires, drive
very carefully for the first 350 miles (500 ki lo
meters) after fitting.
_& WARNING
N ew tires tend to be slip pery a nd mus t al
so be "b roken -in" . Be s ure to remembe r
this dur ing the fi rst 350 mi les ( 500 kilo
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit
uations that m ight require sudden, hard
braking.
Avoid damaging the
vehicle
When you a re d rivi ng on poo r roads, or over
cu rbs, ste ep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoile rs and ex ha ust
s ystem parts do not bot tom o ut and get dam
aged.
T his is espec ially true for veh icles with low
s lu ng chassis (s por ts chassis)* and fully load

whe n driving through water, for examp le on
flooded roads:
- The wa ter must not be any hig he r th an the
bottom of the vehicle bo dy.
- Do not dr ive faste r than wal king speed.
Page 191 of 286

A WARNING 1= ~
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 brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
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 an environmentally sound manner.
11-Always use lead -free gaso line¢ page 201,
Fuel supply .
"'"Never run the tank down all the way to emp
ty.
11-Never put too much motor oil in your engine
¢ page 211, ~ Adding engine oil .
11-Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere .
Drivin g and en vironm ent 18 9
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert
er and proper f unct ion ing of the engine.
A WARNING
- The temperature of the exhaust system
is high, both when driving and after stop
ping the eng ine.
- Never touch the exhaust tail pipes once
they have become hot. This could result in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, br ush,
fue l spill or other material wh ich can
cause a fire .
- Do not apply additional undercoating or
ru stp roof ing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con
ve rter or heat shield s. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just o ne tank filling with
leaded fuel w ill already ser iously de
grade the performance of the catalytic
converter .
- Do not exceed the cor rect engine oil level

-Do not drive until the f ue l t ank becomes
comple tely empty . The engine co uld m is
fire . Unburned fuel could also get into
the exhaust system and this co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is mov ing.
- Do not continue to operate your vehicle
under these conditions, as othe rwise fuel
can reach the catalyt ic converter. Th is

- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaust gas can have a sulfur-like exhaust gas smell under

Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors:
- yo ur persona l dr iving style
- operating conditions
- tec hnic al lim itations
If you anticipate what you need to do next and
d rive economically, you can eas ily cut your
f u el cons umption by 10 -15 pe rcen t. T his sec- t
ion w ill give you some tips on how you can
help the environment and your pocketbook .
(D Tips
The cons umption estima tes as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption on the road, which will va ry depending upon vehi
cle load and speed, road and weather con
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating .
.. Avo id u nnecessary accelerating and brak ing.
Vehicles use the most fue l when they are ac
ce lerat ing. If you ant icipate what is going to
happen next, you wi ll need to brake less and,
t h us, acce lerate less . Let the veh icle coast
whenever possible -for example when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce lerat ing gently red uces fue l cons ump
t ion, eng ine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en
gine noise increase disproportionate ly at h igh
speeds. If you drive at approximately three quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weathe r con
ditions pe rm it.
