_& WARNING
Always take the key with you whenever you
leave your vehicle. The electronic immobil­
izer can be deactivated w ith the key, so
this could make it possible for unauthor­
ized persons to star t the engine and oper­
ate vehicle systems such as the power win­
dows or sunroo f. This can increase the risk
of serious injury.
(D Tips
-The vehicle cannot be started if an unau­
thorized key is used .
It may not be poss i­
ble to start the vehicle under certain cir­
cumstances, for example if there is an ­
other radio module like the key from an­
other vehicle or a transponder on the
same keychain.

for a complete roof rack system. Additiona l
attachments or carrier systems are needed
to transport luggage and sports equipment.
We recommend using roof racks from the
Audi original accessories program.
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof¢
fig. 57.
-We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner's literature in the
vehicle .
When should the roof rack be remo ved ?
-Before going through an automatic car wash
(it is best to ask the car wash operator for
advice).
- When not in use, to reduce fuel consump­
t ion, w ind no ise and to guard against theft .
A WARNING
-Use of an unapproved roof rack or incor­
rect mount ing of an approved roof rack
can cause the roof rack or the items at­
tached to it to fa ll off the roof onto the
road.
- Objects fall ing from the roof of a veh icle
can cause a c rash and persona l injury.
- Only mount the roof rack on the desig­
nated locations on the roof¢
fig. 57.
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving w ith a roof rack system,
changes to the center of g ravity and wind
resistance can change the veh icle han­
dling and lead to a collision. A lways
adapt your driving and your speed to the
c u rrent conditions.
(D Note
- Your veh icle warranty does not cover any
damages to the veh icle caused by using
r oof racks or mo unting structures not
approved by Audi for your vehicle. The
same applies to damage resulting from i ncorrect roof rack installation.
S eat s an d sto rage 63
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make s ure everyth ing is se ­
curely tightened. If necessary, ret ighten
the mountings and check the entire sys­
tem from time to time.
- After mount ing a roof rack system, or
when you transport objects on the roof
of your vehicle, the height of the veh icle
is naturally increased . Be careful when
dr iving unde r low bridges or in parki ng
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
roo f* do not come in to contact with the
roo f rac k.
Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down .
.,. Always dis tribute the loads on the roof rack
even ly .
.,. Always attach items to the roof rack securely
before you drive off .
T he maxim um permissible roof we ight is
1 6 5 lb (75 kg ). The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you are carrying. You must a lso
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 tota l maximum permissible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the
max imum capacity specified by the manufac­
ture r of the roof rack system .
A WARNING
Weak, damaged or imprope r straps used
to secure items to the roof rack can fail
during ha rd braking o r in a coll is ion and
cause ser ious persona l injury .
.
•

64 Seats and storage
-Make sure the roof rack is installed exact­
ly as specified above
r::;, page 62.
- 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.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
vehicle, the permissible axle weights and
the permissible total weight of your veh i­
cle
r::;, page 286, Weights.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
using fuel unnecessarily. So remove the
roof rack after using it .

Warm and cold Climate control system
Description
Different systems cou ld be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and panorama sunroof* are closed. If
there is a build-up of heat inside the vehicle,
ventilation can help to speed up the cooling
process . For this reason, the windows and
panorama sunroof can be opened from the
outside .

closing
Pollutant filter
T he pollutant filter removes pollutants such
as dust and pollen from the air .
Key recognition
You can store various settings for the manua l
and automatic
climate control system* and
assign them to the key being used .
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free
of ice, snow and fog .
- Become familiar as quickly as possible
with the correct use and function of the cl imate control system, especially with
the defrosting and defogg ing funct ion .
- When the temperature is below freezing,
only use the windsh ield washer system
after the w indshield has been warmed by the cl
imate control system . The washer
fluid could freeze on the windshield and
impair visibility.
(D Note
- If you suspect that the climate control
system is damaged, switch the system
off to prevent further damage and have
it checked by an authorized Audi dealer
or authorized Audi Service Facility.
- Repairs to the Audi climate control sys­
tem require special technical knowledge
and special tools. See an authorized Audi
dealer or authorized Audi Serv ice Facility .
® For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter
the air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can dr ip and form a puddle of water un­
der the vehicle. This is normal and does
not mean there is a leak.
- 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.

Automatic
transmission S tronic-transmission
Introduction
Applies to vehicles: with S tronic transmiss ion
Your vehicle is equipped with an electronical­
l y -controlled DSG transmission called S tronic.
T wo independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
T he transmission upshifts or downshifts auto­
matically. The driving style continuously influ­
ences the selection of the driving program .
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel effic iency .
T he 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) r=> page 114,
Shifting manually (tiptronic mode) .

pos ition if the ignition is switched on .
N -Neutral
The transm iss ion is in idle in this position .
DIS -Normal position for driving forward
In the D/S selector lever position , the trans ­
mission can be operated either in the normal
D mode or in the S sport mode. To select the S
spor t mode, pull the selector lever back brief­
ly. Pulling the lever back again will select the
normal D mode . The instrument cluster dis­
play shows the selected driving mode.
In the
normal mode D, the transmission auto­
matically selects the suitable gear ratio . It de­
pends on engine load, vehicle speed and driv­
ing style .

198 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, drive 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 for your vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
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 gaso line r=;, page 210,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
r=;, page 223, Adding engine oil <t:::r..
> Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic 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 critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
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 contact with dry grass, brush,
fue l spill or other material wh ich 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 driving, the
substance used for undercoating could
overheat and cause a fire.
(D 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
r=;, page 223.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel

can reach the catalytic 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 accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance 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 Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with d iesel eng ine
The diesel particulate filter fi lters nearly a ll of
the soot part icles out of the exhaust. The fil­
ter cleans itse lf automatically under normal
driving conditions. If the filter cannot clea n it­
self (for examp le, because you are only driving
short d istances) , the fil ter becomes clogged
with soot and the
II symbo l for the diesel
particulate f ilter illum inates ~ page 23.
A WARNING
- Do not park yo ur vehicle ove r flammable
materials such as g rass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could
start.
Dri ving and the en vironm ent 199
Placing your vehicle
out of service
If you would like to take your vehicle out of
se rv ice for a longer time, contact your author­
ized Audi dealer or qualified repair fac ility .
They w ill advise yo u of impo rtant measures,
such as corrosion p rotection , maintenance
and storage p roced ures. Also follow the infor­
ma tion about the battery ~ page 228 .
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, env ironme ntal impact, and
wea r on your eng ine, b rakes and tires la rgely
depend on three factors:
- your personal d riving s tyle
- operating 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 ion by 10-15 percent. This sec­
tion w ill give you some tips on how you can
help t he env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTECTION AGENCY
(EPA) and Transpo rt Canada may not corre­
spond to your actual consumption on the r oad, which will va ry depending upon vehi ­
cle load and speed, ro ad and weather con­
ditions, trip leng th, etc.

200 Driving and the environment
Vehicles use the most fuel when they are ac­
celerati ng. If you anticipate what is going to
happen next, you will need to brake less and,
thus, accelerate less. let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well be low your car's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine noise increase disproportionately at hig h
speeds . If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never dr ive faster
tha n the posted speed limit and weather con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.. Sh ut the engine off when you are not dr iving
the vehicle.
.. Do not warm up the vehicle by letting the
engine run at idle.
It is efficient to switc h off the engine when
stopped at railroad crossings and long red
lights. Turning the engine off for just 30-40
seconds saves mo re fuel than is burned by
start ing the eng in e again.
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
d rive away as soon as you sta rt the eng ine and
avoid ru nning a t high RPM wh ile the engine is
still warming up .
(D Note
Do not leave engine i dling unattended af­
ter start ing. If wa rning lights sho uld come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat , w hich could result in over­
hea ting o r othe r damage to the veh icle or
othe r property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.. Have your ve hicle serviced at regu lar inter-
vals.
Having your veh icle regu larly serviced by an
authorized Aud i dealer helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your veh icle not on ly affects its safety and
ability to ho ld its va lue, i t also affects
fuel
c onsumption .
Check your oil each t ime you fill your tank.
The amount of oi l used is re lated to engine
l oad and speed.
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certain
mileage has been driven .
You m ust drive your ve hicle abou t 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion .
T his also ap plies to fue l consumption and en ­
gine o utp ut.
(D Note
- Have your veh icle ma inta in ed properly
and i n acco rdance with the service rec­
ommendations in you r W arranty
& Main­
t enance boo klet. l ack of proper ma inte ­
nance as well as im proper use of the ve­
hicle will impair the function of the
em iss ion cont ro l system and cou ld lead
to damage.

-Do not alter or remove any component of
the Emission Contro l System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System and other important veh icle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
~ Try to avoid driving short distances with a
cold eng ine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a cold engine in a mid -size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2 .5 m iles (4 km),
the engine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips wheneve r possible.
The
outside temperature is also critical in this
regard . Your car consumes more fuel in the
winter than in the summer.
