Rear spoiler
Applies to vehicles: with retractable rear spoiler
The rear spoiler improves vehicle handling
and enhances driver control.
Fig. 128 Switc h for rear spo iler
The rear spoiler deploys and retracts . Spo iler
operation can be set for automatic or manua l
operation.
Automatic m ode (no rmal operat ion )
-Automatic deployment: At a speed of about
75 mph (120 km/h), the rear spoiler deploys
automatically.
-Automat ic retraction: When speed drops be ­
low about SO mph (80 km/h), the rear spo il­
er retracts automatically .
Manu al mode
- Manual deployment: Tapping briefly on the
switch
c:> fig. 128 dep loys the rear spo iler .
- Manual retraction: At speeds up to about 10 mph (20 km/h), retract the rear spoiler
by pressing and holding the switch
c:> fig . 128 . At speeds between 10 mph (20
km/h) and 75 mph (120 km/h) , retract the
rear spoiler by tapping on the switch
c:>fig . 128.
_& WARNING
Dr iv ing at higher speeds w ithout the rear
spoiler dep loyed can impair hand ling cha r­
acteristics, making the vehicle harder to
contro l.
- Always make sure that the spoiler is de­
ployed when driving at speeds over
85 mph (140 km/h).
If the rear spoiler
warning/ind icator light in the instru-
Intelligen t technolog y 153
ment cluster comes on, the rear spoiler
may not have deployed .
- Never drive at speeds higher than
85 mph (140 km/h) if the spoiler is not
deployed. Have the spoiler inspected as
soon as possible by an authorized Audi
deale r o r qualified workshop .
- Always obey speed limits and other traf­
fic laws.
_& WARNING
Improper operation of the rear spoiler can
cause crushing injuries.
- Always make sure that nobody, especially
children, is in the way when the rear
spoiler is deployed or retracted .
(D Note
Never push the vehicle or apply force to
the rear spoi ler -it cou ld be damaged.
{!) Tips
C lean the spoiler compartment every 2 to
3 months. The spoiler compartment must
a lways be free of ice, snow, leaves or other
debr is .
Braking
General information
What affects braking efficiency?
Ope rating cond itions and driving habits
The brakes on today's automobiles a re still
subject to wear, depe nd ing largely on operat ­
ing condit ions and driving hab its
c:> .&,. . On
vehicles that are either driven most ly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be checked by yo ur au thor­
ized Audi dealer more often than specified in
the
Warr anty & 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. T his way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes .,.

154 Intellig ent technolog y
down continuously. Pump the brakes at inter ­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Under certain conditions, for examp le, when
d riving through water or ve ry heavy rain, or
even after washing your vehicle , the bra king
effect can be reduced due to moisture (o r in
freezing conditions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the b rakes can be reduced
when the vehicle is driven on a salt -covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake
q .&. .
Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not driven 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 braking
f irmly a few times from a moderately high
speed
Q .&. .
Fa ults in th e brak e system
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circu its may have failed
q .&. .
Low brake flu id 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.
B rake boo ste r
The brake booster increases the press ure that
you gene rate w it h the brake pedal. It works
on ly when the engine is running
.Q .&.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection
q page 224, What should I be
aware of when changing a tire?.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r 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 or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
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 climatic and operat ing
conditions such as passing through wa­
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the b rakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
fu l brake applications.
- Driving for an extended period of time on salt-covered roads without using your brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications .
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
f low to the front brakes is not obstruct-
ed. Otherwise the brake system could
Ill>

overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dealer or qualified workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
The degree of power assist is electronically
matched to vehicle speed.
The power steer ing system ass ists the driver
so that he can stee r the veh icle w ith red uced
phys ica l effort.
Power steering w ill not work if the engine is
off. As a result, the steering wheel w ill be hard
to turn.
& WARNING
If the system develops a prob lem, you
must seek qualified professional assis­
tance.
(D Note
-
If there is an electronic malfunct ion, ser­
votronic
wi ll sti ll function like a conven­
tional power steering system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the
steer ing wheel at low speeds (for example
when parking), -more effort will be re­
quired than usual.
Int ellig ent technolog y 155
-Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authorized Audi dea ler as soon as
possible.
- If a steering malfunction occurs, this is
signaled with the,~ , or .• indicator
lights and a warn ing tone, see.
(D Tips
- If the power steering system sho uld fail,
or if the engine is not running (for exam­
ple, while being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately.

General information
With a ll-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depend ing on your driving style and the road
conditions at the time. See also
c::> page 1 SO.
The all-whee l dr ive concept is des igned for

Winter tires
When dr iving 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 tires) for improved driveability and brak­
ing: these tires must be mounted on
all fou r
wheels. See also c::> page 211, Winter tires. ..,_

Where t ire cha ins are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive ¢
page 212, Snow
chains .
Replacing wheels /t ir es
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with different tread depths. For details see
page ~
page 207, New tires and replacing
tires and wheels.
Off -Ro ad dri ving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road veh icle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 160.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra r isks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should the refore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning) .
If this should occ ur, you
will have no warning from a sudden in ­
crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions. -risk of crash.
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 handles 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 diag nosis, idlin g curre nt 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 current and battery
temperature. This determines the current state o f charge and the power of the battery .
Idling current managem 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 energ y manag ement
While the vehicle is being driven, dynamic en­
ergy ma nagement distr ibutes the energy gen­
era ted accord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
that 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
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
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 lectrica l energy is re­
quired, but only a litt le 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 non e 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 mai n­
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust ­
ment, may not be available . The convenience
f u nctions w ill 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 157
If starting capability is jeo pardi zed 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 e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be­
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili ­
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r­
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
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 . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired 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 no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go
out. •

Driving and
environment
The first 1
1000
miles
(11500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the first 600 mile s (1,000
kilometre s):
.,. Do not use full throttle .
.,. Do not d rive at engine speeds that are more
than 2/3 of the max imimum permitted
RPM .
.. Avoid hig h engine speeds.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometres):
.. Speeds ca n gradually be increased to th e
maximum pe rm iss ib le road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds
when it is cold . T hi s applies whether the
transmission is in N (Neutral) o r in gear.
After the break- in period
.. Do not exceed max imum eng ine 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 pa rts have been broken
i n. How well this break-in p rocess is done de­
pends to a considerable ex tent o n the way t he
ve hicl e is driven d uring the first 1,000 miles
(1, 500 kilome tres) .
(D Note
Extremely high engine speeds a re auto­
mat ic al ly reduced. However, t hese RPM-

limits were programmed for an eng ine
well run-in, not a new eng ine.
@ For the sake of the environment
Do not d rive wi th unnecessar ily h igh en­
gine speeds -upshifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly carefu l for the first 350 miles
(S00 ki lometres) after fitting .
A WARNING
-New tires tend to be s lippery and must a l-
so be "broken-in". Be s ure to remembe r
this dur ing t he firs t 3S 0 m iles (500 kilo­
me tres) . Brake gent ly . Avo id following
closely behind other vehicles or other sit­ uations that m ight require sudden, hard
b raking.
New brake pads
Remember that new brake pads do not have a
full brak ing effect during the first 250 miles
(400 kilometres) after they are installed.
New brake pads have to be "burnished in" be­
fore they have optima l grab¢ .&..
D uring the break-in period, yo u should avoid
putting seve re loads on the brakes . Severe
l oads include, for example, su dden hard brak­
ing, in particular at very h igh speeds or, for
example, on mou nta in passes.
A WARNING
Until t hey develop the maximum "bite" fo r
best stopping power, the s urfaces on new
b rake pads requ ire some "brea king- in" dur­
in g the initial 10 0 to 150 miles (15 0 to
20 0 kilome tres) of normal c ity dr iv ing. Yo u
can compensate for this by press ing the
b rake peda l more f irm ly . This applies
whenever new pads are installed.

160 Driving and en vironm ent
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 exhaust
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
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it 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.
.,. Always use lead-free gasoline ¢ page 176,
Fuel supply .
.,. Never run the tank down all the way to
empty .
.,. Never put too much motor o il in your en-
gine ¢
page 185, Adding engine oil 'l::r. .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
u p" dev ice buil t into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of t he pollu tan ts in the exha ust gas be­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critica lly
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 185.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenan ce booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion 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 p roperly, the exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
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 :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates 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 vary 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.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less. Let the vehicle coast
whenever possible -for examp le 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 maxi -
mum speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.
