Fuel economy messages
Fuel economy messages are disp layed when
fuel consumption is increased by certain con­
ditions ~
fig. 10 . If you follow these fuel
economy messages, you can reduce your vehi­
cle's consumption of fuel. The messages ap­
pear automatically and are only displayed in
the efficiency program. The fuel economy messages turn off automatically after a cer­
tain period of time .
To turn an economy message off immediately after it appears, press any button on the mul­
tifunction steering wheel.
@ Tips
- If the data are deleted in the efficiency
program, those values are also reset in
trip computer .
- Once you have turned a fuel economy
message off, it will only appear again af ­
ter you turn the ignition on aga in .
- The fuel economy messages are not dis­
played in every instance, but rather in in­
tervals over a period of ti me .

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL )
The Ma lfunction Indicator Lamp ( MIL ) ¢'4 in
the instr ument cluster is part of the On-Board
Diagnostic (OBD II) system .
T he wa rni ng/indicator light ill uminates when
the ignit io n is switched on and goes out after
the engine sta rts and the id le has stab ilized.
This indicates that the MIL is working proper­
ly .
If the light does not go out afte r th e en gine
is started, or illuminates while you are dr iv­
ing, a mal function may exist in the engine sys ­
tem.
If the lig ht illum inates, the catalyt ic con­
verter could be damaged .
Contin ue driving
with reduced power (avoid­
ing s ustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your aut horized Audi dea ler.
If the light illuminates, the e lectronic speed
limiter may also be malfunct ioning . For more
information

30 Instruments and warning /indicator lights
has been assigned a code. In case of a ma l­
function, the component will be identified
and the fault stored as a code in the contro l
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 refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢

Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 260 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.

nated locations on the roof¢
fig. 63.
-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 veh icle han­
dling and lead to a collision . Always
adapt you r driv ing and your speed to the
c u rrent conditions.
(D Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using
r oof racks or mount ing structures not
approved by Audi for your vehicle . T he
same applies to damage resulting from
incorrect roof rack installa tion.
- Always check t he roof rack moun tings
and hardware before each trip and dur­
i ng a trip to make sure everything is se­
curely tightened . If necessary, retighten
the mount ings and check the entire sys­
tem from t ime to t ime.
S eat s an d sto rage 63
-After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the heig ht of the veh icle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example. This cou ld 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 w ith the
roof rac k.
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
even ly.
"' Always attach items to the roof rack securely
befo re you dr ive off.

Automatic Transmission
S tronic, tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upsh ifts or down­
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most econom ica l
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 113.
Various automatic transmissions may be in­
stalled, depending on the model :
S tronic transmission
The S tronic is a dual-clutch transmission.
Power is transferred using two clutches that
work independently from one another . They
replace the torque convert er used in conven­
tional automatic transmissions and allow the
veh icle to accelerate without a noticeable in­
terruption in traction.
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter .

204 Driving and en vir onm 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 load­
ed veh icles .
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 higher tha n the
bottom o f the vehicle body.
- Do not d rive 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 rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(]) Note
-Vehicle components such as the eng ine,
transmission, suspension or e lectr ica l
system can be severe ly damaged by driv­
ing through water.
- Always switch
off the Start-Stop-System
when driving through water¢
page 81.
(D Tips
-Check the depth o f the water before driv ­
ing through it.
- Do no t stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r your vehi­
cle to drive through safely.
-
- Avoid driving through salt water because
it can cause corrosion .
Catalytic converter
Applies to vehicles : w ith gasoli ne e ngi ne
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.
.. Always use lead-free gasoline ¢ page 217,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much motor o il in your eng ine
¢ page 229, Adding engine oil~-
.. Never try to push- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
u p" dev ice built into the exhaust system of
the ve hicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
f ore they are re leased into the atmosphere.
The exclusive use of unleaded fuel is c rit ically
important fo r the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
A WARNING
-
The temperature of the exhaust system is
h igh, both when driving and after stopping
the engine.
- 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 exha ust system may
come in contact with dry grass, brush,
fue l spill or other material which can
cause a fire .
- Do not app ly additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.

M N <( (.J
'SI: ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
(D Note
-Be aware that just one tank fi lling with
le aded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page229.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not switch off the ignition wh ile the
vehicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w it h lead-free super
grade gasoline .
Diesel particulate filter
Appl ies to vehicles : wit h diesel e ng in e
The diesel particulate filter fi lters nea rly a ll of
the soot part icles o ut o f the exhaus t. T he fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it-
Drivin g and en vironm ent 205
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the
II symbol for the diese l
particulate filter illuminates
c> page 21.
A WARNING
-Do not park your veh icle over flammable
mate ria ls such as grass or leaves because
the high temperature of the diesel par­ ticulate fi lter could start a fire.
- Do not apply an underbody protectant in
the exhaust system area or a fi re could
start.
Shutting down vehicle
If you would like your vehicle to rema in inop ­
erative for a longer per iod of t i me, contact an
Audi o r other spec iali zed dealer. They can ad­
vise you on necessa ry precautions e.g. co rro­
s ion p reven tion, maintena nce and s torage.
Pay attention to additional information con ­
cerning the battery . Refer to

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, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10-15 percent . T his sec ­
tion w ill give you some tips on how you can
help the env ironment and your poc ketbook. ..,_ •
