28 Instr uments and warning/indicator lights
Open door/hood /rear lid warning
Fig. 14 Display : doors and rear lid open
With the ignition switched on, the warning il­
luminates when at least
one door or the hood
or the rear lid is not closed . The symbol also
shows you
which door(s) or lid is not closed .
In the illustration
c:> fig. 14 it is the driver's
door and the left rear door.
On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL }
The Malfunction Indicator Lamp (MIL)¢• in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
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
is started, or illuminates while you are driv­
ing, a malfunction 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 sustained high speeds and/or rapid accel­
erat ions) and have the condition corrected .
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information
c:> page 29, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:> page 230.
On-Board Diagnostics
Fig. 15 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em iss ion contro l 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 also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem .
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler cap is properly closed
c:> page 230.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBO) .
In order to connect the specia l diagnostic
equipment, push the plug into the Data Link
Connector (OLC). The DLC is located to the
right of the hood release
c:> fig. 15.
Your authorized Aud i dealer or a qualified
service station can interpret the code and per­
form the necessary repair.
A WARNING ""-=--
Do not use the d iagnost ic connector for
personal use. Incorrect usage can cause
malfunctions, which can increase the risk
of a collision!

A WARNING ,~
- When you lock your vehicle from outside,
nobody - especially children - should re­
main inside the vehicle. Remember,
when you lock the vehicle from the out­
side the windows cannot be opened from
the inside.
- When you leave the vehicle, always take
the ignition key with you. This will pre­
vent passengers (children, for example)
from accidentally being locked in the ve­
hicle should they accidentally press the
power locking switch in the doors.
- Do not leave children inside the vehicle
unsupervised. In an emergency it would
be impossible to open the doors from
the outside without the key.
- Applies to vehicles with power side door
closer*:
- When closing a door, make sure noth­
ing can interfere with the door. This
could cause serious personal injury.
- You can stop the door from closing at
any time by pulling on the inside or
outside door handle.
@ Tips
-In the event of a crash with airbag de­
ployment all locked doors will be auto­
matically unlocked to give access to the
vehicle occupants from the outside.
- If the power locking system should mal­
function, you can lock the driver's door
using the mechanical key¢
page 36.
- If
the power locking system should fail,
you can still open the fuel tank flap in an
emergency¢
page 231.
-You are well advised not to keep valua­
bles inside an unattended vehicle, visible
or not. Even a properly locked vehicle
cannot provide the security of a safe.
- If the LED in the upper edge of the driv­
er's door panel comes on for about 30
seconds after the vehicle is locked, there
is a malfunction in the power locking or
the anti-theft warning system. Have the malfunction corrected by an authorized

72 Seats and storage
-When not in use, to reduce fuel consump­
tion, wind noise and to guard against theft.
A WARNING
- Use of an unapproved roof rack or incor­
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the
road .
- Objects falling from the roof of a vehicle
can cause a crash and personal injury .
- Only mount the roof rack on the desig­
nated locations on the roof
c::> fig. 7 4.
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han­
dling and lead to a collision . Always
adapt your driving and your speed to the
current conditions.
- Your vehicle warranty does not cover any
damages to the vehicle caused by using
roof racks or mounting structures not
approved by Audi for your vehicle. The
same applies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make sure everything is se­
curely tightened. If necessary, retighten
the mountings and check the entire sys­
tem from time to time.
- After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the height of the vehicle
is naturally increased. Be careful when
driving under low bridges or in parking
garages for example . This could cause
damage to the load and even the vehicle itself.
- Make sure the open rear lid and the sun­
roof* do not come into contact with the
roof rack.
Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down.
.. Always distribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack secure-
ly before you drive off.
The maximum permissible roof weight is
220
lb (100 kg).
The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you are carrying. You must also
not exceed the maximum load weight for the
roof rack you are using.
When using a roof rack system which has a lower load carrying capacity, you must not use
up the total maximum permissible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the
maximum capacity specified by the manufac­
turer of the roof rack system .
A WARNING ,_
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause serious personal injury .
- Make sure the roof rack is installed exact­
ly as specified above
c::> page 71.
-Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shifting or flying for­
ward .
- Items on the roof rack must always be securely mounted .
- The use of a roof rack can negatively af­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
the vehicle's aerodynamics, center of
gravity and overall handling. Always
drive slowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.

78 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof* are closed . If the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pol lutant filter removes pollutants such
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
I f you drive your vehicle in an a rea with high
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The climate control settings are a utomat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents. -
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and funct ion of the heat ing
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ sh ie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.

When stopping at a traffic signal or stopp ing
i n city traffic, the parking brake can be ap­
p lied . The vehicle does not have to be held
with the footbrake. The park ing 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 vehicle starts to move .
Starting on slopes
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
i ng back. The braking force of the parking
brake is not released until sufficient dr iv ing
force has been bu ilt up at the whee ls.
O') 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(®) pulled and depress the
acce lerator. The park ing brake stays applied
and prevents the vehicle from rolling back­
ward .
.. You can release t he sw itch C®l once you are
s u re that yo u are develop ing eno ugh f or­
wa rd momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (veh icle
and trai le r) and the severi ty of the in cli ne, you
may roll backwards as you sta rt. Yo u can pre ­
ve nt roll ing backwards by holding the parking
brake switch C®) p ulled out and acce lerating -
just as you would when starting on a hill with
a conventional hand brake.
On th e ro ad 87
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
.. In an emergency, pull the sw itch(®) and
cont inue to pull it to s low your ve hicle down
w ith the park ing brake.
.. As soon as you release the switch C®> or ac-
celerate, the b ra ki ng process stops.
If you pu ll the switch C®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy brak ing f unction is initia ted . T he ve hicle is
braked at all fou r whee ls by activating the hy­
d raulic brake sys tem. The brake pe rform ance
is simila r to making an emergency stop~ .&..
In order not to act ivate the emergency brak­
ing by mis take, an audib le wa rn ing tone (buz­
z er) so unds whe n the switch(®) is pulled . As
soon as the sw itch<®> is re leased, or the accel­
erator peda l is depressed, emergency braking
stops.
_& WARNING
Emergency braking should only be used in
an emergency, when the normal foot bra ke
has fa iled or the brake pedal is obstructed.
Using the parking brake to pe rform emer­
gency b rak ing will slow your vehicle down
as if you had made a full bra ke application .
T he laws of physics cannot be su spended
even wi th ESC and i ts asso ciated compo­
nents (ABS, ASR , ED L) . In corners and
when road or weather con ditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

Automatic Transmission
tiptronic (8-speed
transmission)
Introduction
Your vehicle is equipped with an electronically
controlled 8-speed automatic transmission .
Upshifting and downshifting occurs automati­
cally and is controlled electronically. The driv­
ing style continuously influences the selection
of the driving program.
When a
moderate driving style is used, the
transmission selects the most econom ical
driving mode. It will then change up early and
delay 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 select the gears
manually (tiptronic mode) ¢ page 118.

tion, move the selector lever forward/back
until you fee l the first pressure point. The
selector lever will return to its original posi­
tion .
.. To skip over one (or two) selector lever posi­
tions, move the selector lever past the first (and second) pressure point into the desired
position. The selector lever will return to its
original position.

206 Driving and environment
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
¢ page 10.
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 .
_& 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 "broken in" before
they have optima l grab ¢.& . The break-in pe­
r iod can be conside rably longe r for vehicles
with ce ram ic brake rotors *. Yo u can co m pen­
sate for this s light ly red uced b ra ki ng power by
pushing ha rder on the br ake peda l.
During the break- in pe riod, you should avo id
putting seve re loads on the bra kes. Seve re
loads include, f or examp le, sudden ha rd b ra k­
i ng, in particular at very high speeds or, for
example, on mountain passes.
_& WARNING
N ew brake pa ds don 't have the best stop ­
p ing power and must be "broken-i n" dur­
i ng the initia l 100 to 150 miles (150 to
200 kilometers) of norma l city driving. You
ca n compe nsate for this by p ressing the
b rake pedal mo re fi rm ly. This also applies
l ater wh en new pads are i nstalled .

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 228,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine ¢
page 238, 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 238.
-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 207
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not swi tch 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 o f 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. •
