against the rear window could damage the
heating wires for the rear window defogger.
@ Tips
-A vent slot is located between the shelf and
the rear window. Do not block the vent with
any items you may place on the rear window
shelf.
- Do not place bulky items on the rear window
shelf as they could restrict or block the driv­
er's vision in the rear view mirror .

• Always read and follow the instructions provid­
ed by the roof rack manufacturer when instal­
ling the roof rack system .
If luggage or cargo is to be carried on the roof,
you must observe the following :
- Only use roof racks approved for your vehicle.
These approved roof racks are the basis for a complete roof rack system. Additional attach­
ments or carrier systems are needed to trans­
port luggage and sports equipment . We recom-
Seats and storage
mend 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
c::> fig. 64.
- We recommend that you keep the installation
instructions for your roof rack system together
with your Owner's literature in the vehicle.
When should the roof rack be removed?
-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 consumption,
wind noise and to guard against theft .
_& WARNING ,_____ -
- Use of an unapproved roof rack or incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached 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 designated
locations on the roof
c::> fig . 64.
- The roof rack system must be installed ex­
actly according to the instructions provided.
- When driving with a roof rack system,
changes to the center of gravity and wind re­
sistance can change the vehicle handling
and lead to a co llision. Always adapt your
driving and your speed to the current condi­
tions.
(D Note
- 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 during a trip
to make sure everything is securely tight­
ened. If necessary, retighten the mountings
and check the entire system from time to
time. ..,.

Warm and cold Climate control system
Description
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It
is the most effect ive when the windows and sun­
roof are closed. If there is a build-up of heat in ­
side the vehicle, ventilation can help to speed up
the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensat ion from the cooling system can drip
and form a puddle of water unde r the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filte r removes pollutants such as
dust and pollen from the ai r.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the a ir condit ioner can
properly work.
If you drive your vehicle in an area with high air
pollution, the filter may need to be changed
more frequently than spec ified in your Audi Wa r­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Adv isor for advice.
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
_&. WARNING
Reduced visibility is dangerous and can cause
accidents .
- For safe dr iv ing it is very important that all
windows be free of ice, snow and condensa­
tion .
Warm and cold
-Comp letely familiarize yourse lf with the
proper use and funct ion of the heating and
ventilation system and especially how to de­
fog and defrost the windows.
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshie ld first, using the heat­
ing and vent ilation system. The washer solu­
tion may freeze on the windsh ield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repairs to the Audi air conditioner require
special techn ical knowledge and spec ial
tools. Contact an authorized Aud i dealer for
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 slots (in front of the
w indshield) free from ice, snow and debris
in order to main tain the proper function of
the climate control system.
- T he energy management system may switch
the seat heating * or rear window defroster
off temporarily. These systems are avai lab le
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of cloth ing on
the luggage compartment cover, ensure
that the openings are not covered.

Automatic transmission
S tronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most economical driving
mode.
It will then change up early and delay the
downshifts to give better fuel economy.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty driv­
ing style
characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ~ page 85.
The S tronic is a dual-clutch transmission . Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
transmissions and allow the vehicle to accelerate
without a noticeable interruption in traction.
Selector lever positions
Fig. 83 Display in the instru ment cluster: selector lever in
pos it ion P
The selector lever position engaged appears next
to the selector lever as well as in the instrument
cluster display .
Automatic transmission
P - Park
In this selector lever position the transmission is
mechanically locked. Engage P only when the ve­
hicle is
completely stopped¢.& in Driving the
automatic transmission on page 83.
To shift in or out of position P, you must first
press and hold the brake pedal and then press
the release button in the selector lever handle
while moving the selector lever to or from P. You
can shift out of this position only with the igni­
tion on.
R- Reverse
Select R only when the vehicle is at a full stop
and the engine is running at idle speed¢.& in
Driving the automatic transmission on
page 83.
Before you move the selector lever to R, press
both the release button in the hand le of the se­
lector lever
and the brake pedal at the same
time .
When the ignition is on, the backup lights illumi­
nate when the selector lever is moved into R.
N - Neutral
The transmission is in neutral in this position.
Shift to this position for standing with the brakes
applied
~ .& in Driving the automatic transmis­
sion on page 83.
When the vehicle is stationary or at speeds below
1 mph (2 km/h), you must always apply the foot­
brake before and while moving the lever out of N.
D/S - Normal position for driving forward
In the D/S position, the transmission can be oper­
ated either in the normal mode Dor in the sport
mode S. To select the sport mode S, pull these­
lector lever back briefly. Pulling the lever back
again will select the normal mode D. The instru­
ment cluster display 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 driving
style.

Driving and the
environment
Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 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 .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first
350 miles (500 kilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
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 f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water . ""
177

Driving and th e environment
(D Tips
-Check the depth of the water before driving
through it.
- Do not stop the veh icle, 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 vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Warming up and cooling down
By carefully warming up and cooling down your
veh icle, you can help ensure that it is not over­
stressed unnecessar ily du ring sporty dr iv ing.
When warming up, the vehicle is driven at a max­ imum engine speed of 6000 RPM in order to ra ise
the engine oil temperature to a m inimum of
140 °F (60 °C). T he tires also only reach their full
road holding capab ility once they have wa rmed
up.
The cooling fan can continue to run in your vehi­
cle after the eng ine is switched
off. However,
d riving the vehicle to cool it dow n is part icu larly
important. During sporty d riving, the engine and
brakes , the exhaust system, and the transmission
all become extremely hot. Before you park the
vehicle, you should drive it for a few mi les/kilo ­
meters at light load in the low rpm range to al­
low it to cool down.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in on
environmentally sound manner .
.. Always use lead -free gasoline c::> page 183,
Fuel supply.
.. Never ru n the tank down a ll the way to empty.
.. Neve r pu t too m uch motor oil in your engine
c::> page 191, 't:::?: Adding engine oil .
178
.. Never try to push -or tow-start your vehicle .
The catalytic converte r is an effi cient "clean-up"
device b uilt into the exha ust system of the veh i­
cle. The cata lytic conve rter burns many o f the
po llutants in the exhaust gas before they are re­
l eased into the atmosphere.
The exclusive use of unleaded fue l is c ritically im ­
po rtant for the life of the catalytic conver ter and
proper functioning of the engine .
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. Th is could resu lt 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, fuel spill or
other material which can cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iving, the substance
used for unde rcoat ing could overheat and
cau se a fire.
@ Note
- Be aware that just one tank fill ing with lead­
ed
fuel w ill al ready ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
c::>poge 191.
-Do not drive until the fue l tank becomes
completely empty . T he engine cou ld m isfire .
Unburned fu el could also get into the ex­
haus t sys tem a nd this could cause the cata­
lyt ic converte r to overheat.
- Do not turn
off the ignition while the vehicle
is
moving.
- Do not continue to operate your veh icle un­
der these condi tions, as otherwise f uel can
re ach the cat aly tic converter. This could re ­
s u lt in ove rheat ing of the c onve rter, requ ir­
ing its replacement .

dations in your Warranty

book let.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used . Using a differ­
ent brand of fuel may help, or filling the tank
w ith lead-free super grade gasoline.
Shutting down vehicle
If you wou ld like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi
or other specialized dealer. T hey can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery. Refer to
c:;, page 196.
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi­
ronment and your pocketbook .
Driving and the environment
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
will vary depending upon vehicle load and
speed, road and weather conditions, tr ip
l ength, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler ­
ating .
.. Avoid unnecessary accelerating and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen next, you will need to brake less and , thus, accel­
erate less. Let the veh icle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im ­
proves your mileage .
.. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumpt ion, exhaust emiss ions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fue l consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
.. Shut the eng ine off when you are not driving
the vehicle.
.. Do not warm up the vehicle by letting the en-
gine run at idle .

Driving and th e environment
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rai lroad
crossings, or at traff ic lights that have long waits
on red. Turning the eng ine off for just 30-40 sec­
onds saves more fuel than is burned starting the
engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and nox ious em issions are especially h igh when
the engine is warm ing up. So you should dr ive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up.
{[) Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended id ling a lso produces
heat, wh ich co uld resu lt in overheating or ot h­
er damage to the vehicle or other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
~ Have you r vehicle se rv iced at regular i nte rva ls.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
r u ns p roperly and economically. The condition of
your veh icle not only affe cts its safety and ability
to hold its va lue, i t also affects
fue l con sump ­
tion.
Ch eck your oil each tim e you fill your tank .
The amount of oil used is related to engine load
and speed .
It is normal for the oil consumption of a new en­
g ine to reach its lowest value after a certain mile­
age has been driven.
You must drive yo ur vehicle about 3,000 miles
(5,000 ki lometers) before you can properly as­
sess o il consumption .
This a lso applies to fuel consumption and engine
output .
180
(D Note
-Have your veh icle ma intained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and cou ld lead to damage .
- Do not alter or remove any component of the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, sw itches, ignit ion wires,
valves, which a re des igned to p rotect your
vehicle's Emission Control System and other
impo rtant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Tr y to avoid dr iv ing sho rt distances w ith a co ld
eng ine .
The eng ine and cata lytic converter have to reach
their opt imal
op erat ing temperature to reduce
fuel consumpt io n and noxious em issions effec­
tive ly.
Just after starting, a co ld eng ine in a mid -s ize car
o nly achieves a fuel economy of 6-8 m iles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg ( 20 l/100
k m). After about
2.5 mi les ( 4 km) , the eng ine is
at i ts p roper operating tempera ture and fuel
economy has reached a normal level. So you can
see that yo u should avo id short trips whenever
poss ib le.
The
outside temperature is also cr itical in th is re­
gard. Your car cons umes more fuel in the winter
than in the summer.

Fuel and Refueling

Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recomme nded for yo ur vehicle is unlead­
ed premium
grade gaso line. A udi recommends
usi ng TOP TIER Detergent Gasoline w ith a min i­
mum octane rating of 91 AKI (95 RON). For more
i nformation on TOP TIER Detergent Gaso line,
p lease go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your e ng ine can a lso be found o n a label located
on the inside of the fue l filler flap. This rating
may be specified as AKI or RON.
Your veh icle may also be operated using unlead­
ed regular gaso line with a minimum octane rat­
in g of 87 AKl/9 1 RON . Howeve r, using 87 AKI/91
RON octane fue l will s ligh tly reduce eng ine per­
fo rma nce.
Use unleaded gasoline only . Unleaded gasoline
i s availabl e thr oughout the USA, Canada, and in
most European cou ntries. We recommend t hat
you do not t ake yo ur vehicle t o areas or countr ies
w here unle ade d gaso line may no t be availabl e.
For mo re info rmat io n on r efueling your ve hicle ,
see

Octane rating
Octane rating ind icates a gaso line's ability to re­
sist engine damaging "knock" caused by prema­
ture ign ition and detona tion. The refor e, buying
the co rrect g rade of gasoli ne is very important to
