the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
i s started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem .
If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing susta ined high speeds and/or rapid accel­
erat ions) and have the condition corrected.
Contact your authori zed Audi dealer .
If the light illuminates, the electronic speed
limiter may also be ma lfunctioning. For more
information
Q page 30, Electronic speed
limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
Qpage227.
On-Board Diagnostics
Fig . 16 Locat io n of Data Link Co nnector (D LC)
On-Board Diagnostics monitors the compo­
nents o f your emission control system. Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault stored as a code in the control module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem. If the light illuminates after a refuelling,
stop the veh icle and make sure the fuel filler
cap is properly closed
Q page 22 7. In order to make an accurate diagnosis, the
stored data can on
ly be displayed using spe­
c ial diagnostic equipment (generic scan tool
for OBD).
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (D LC). The DLC is located to the
right of the hood release~
fig. 16.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING
-Do not use the diagnostic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!
Electronic speed limiter
-
Your vehicle may be factory equipped w ith
t ir es that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle also has an e lectronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information
Q page 257.
If the engine control unit receives faulty vehi­
cle road speed signals, the Malfunction Indi­
cator Lamp (MIL)
¢fj will illuminate . If this
occurs, contact the nearest authorized Audi
dealer for assistance.
S models
Your vehicle's top speed is electronica lly limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica­
tor Lamp (MIU¢.§ will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.

rect mounting of an approved roof rack

80 On the road
Starting and automatically releasing the
par king brake
.. When you sta rt to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopping
in city traffic, the parking brake can be ap­
plied. The veh icle does not have to be held
with the footbrake. The parking brake elimi­ nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the veh icle sta rts to move .
Starting on slopes
When starting on inclines, the starting assist
prevents the vehicle from unintentionally roll­
ing back . The braking force of the parking
brake is not released until sufficient dr iving
fo rce has been bu ilt up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's safety belt is engaged in the buck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch l pulled and depress the
accelerator. The park ing brake stays applied
and prevents the vehicle from rolling back­
ward.
.. You can release the switch
C®l once you are
sure that you a re developing enough for­
ward momentum at the wheels as you de­
press the accelerator .
Depending on the weight of the rig (vehicle
and trai ler) and the seve rity of the incline, you
may roll backwards as you start. You can pre­
vent rolling backwards by holding the parking brake switch(®) pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake .
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
.. In an emergency, pull the switch C®l and
con tinue to pull it to slow your vehicle down
w ith the park ing brake.
.. As soon as you release the switch (®) or ac-
celerate, the brak ing process stops.
If you pull the switch C®l and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy brak ing funct ion is initiated . T he vehicle is
braked at all fou r whee ls by activating the hy­
draulic brake system. The brake performance
is similar to making an emergency stop~&. .
In order not to act ivate the emergency brak­
ing by mis take, an audib le warning tone (buz­
zer) sounds whe n the switch(®) is pulled . As
soon as the sw itch C®l is released , or the accel­
erator pedal is depressed, emergency braking
stops.
_& WARNING
-Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking brake to perform emer­
gency braking will slow your veh icle down
as if you had made a full brake application .
The laws of physics cannot be suspended
even with ESC and its associated compo­
nents (ABS, ASR, EDL) . In corners and
when road or weather conditions are bad,
a full brake application can cause the vehi­
cle to skid or the rear end to break away -
risking an accident.
Start-Stop-System
Description
Applies to vehicles: with Start -Stop -System
T he Start -Stop-System can help increase fuel
economy and reduce CO 2 emissions.
In the Start-Stop-mode, the engine shuts off
automat ically when the veh icle is stopped,
such as at a traffic light. The ignition remains .,.

Automatic Transmission
S tronic ®, tiptronic
Introduction
Applies to vehicles: with S tronic/tiptronic
The automat ic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is se lected .
When a
moderate driving style is used, the
transmission selects the most economica l
driving mode. It will then change up ear ly and
de lay the downshifts to give better fuel econ­
omy.
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also se lect the gears
manually (t iptronic mode ) i=> page 113.
Various automatic transmissions may be in­
stalled, depending on the model:
S tronic® transmission
The 5 tronic ® is a dual-clutch transmission.
Power is transferred using two clutches that
work independently from one another . They
replace the torque converter used in conven­
tional automatic transmissions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction .
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter .

Driving and
environment
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 drive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
... Avoid hig h engine speeds.
From 600 to 1,000 mile s (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 per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transm ission is i n N (Neutra l) or in gear.
After the break-in period
... Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next hig her gear
before
reaching the red area at the end of the tach­
ometer scale
c:> page 11.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
in . How well this break- in p rocess is do ne de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1, 500 k ilome ters).
0 Note
E xtremely high engi ne speeds are auto­
mat ica lly reduced. However, these rpm
lim its are progr amme d for an engine well
r u n- in, not a new engine .
{® For the sake of the environment
Do not drive 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
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing .
A WARNING
New tires tend to be sl ippery and mus t al­
so be "broken -in" . Be s ure to remember
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 .
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled .
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab
c:> A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the
br ake peda l mo re f irm ly . This also applies
l ater when new pads are installed.

Catalytic converter
It is very important that your emission con­trol 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 225,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 235, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "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.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust pipes, catalytic con­
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 235.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 205
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not switch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec­
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam­
aged.
T h is is espec ially true for veh icles w ith low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles. •
