------~~ ~
Fig. 65 Attachm ent points for the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:
- Only a specially designed roof rack may be used
on your vehicle. These roof racks are the basis
for a complete roof rack system. Additional at ­
tachments/carrier systems are necessary to
transport luggage and sports equipment . We
recommend roof racks and attachments from
the Audi Genuine Accessories program.
- When installing the roof rack, make sure that it
is mounted only at the designated points on
the roof
c> fig . 65 .
- The permissible roof load for your vehicle is
220 lbs (100 kg). The roof load is the total of
the weight of the roof rack, the attachments
and the cargo you are carrying . However, you
must also note the permitted load of the carri­
er system being used. For the permitted axle
load and the permitted total vehicle weight, re­
fer to
c> page 255.
Seats and storage
A WARNING
--Follow the installation instructions provided
with the roof rack system. If you do not se­ cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and cause an accident.
- Using a roof rack system increases the r isk
of an accident, because it changes the driv­
ing characteristics by shifting the center of
gravity and/or the increasing the surface
area exposed to wind. Adapt your driving
and speed to the current cond itions.
CD Note
Make sure that the luggage compartment lid
and the sunroof* do not come into contact
with objects on the roof when they are open.
(,® For the sake of the environment
Your vehicle will require more fuel due to the
increased wind resistance. So remove the roof
rack after using it.

Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
insid e the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reach ed a suffici ent tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .

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
contro l system, especially with the defrost­
ing and defogg ing function.
- When the temperat ure is below freezing,
only use the windsh ield washer system after
60
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visibi li­
ty .
Cl) Note
-If you suspect that the cl imate contro l sys­
tem is damaged, switch the system
off to
prevent further damage and have it checked
by an authorized Aud i dealer or authorized
Audi Service Facility .

(D Tips
- To prevent interference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice ,
snow or leaves.
- Conde nsation from the coo ling system can
dr ip and fo rm a pudd le of water under the
vehicle. This is norma l and does not mean
there is a leak.

Economical and environmentally-friendly
driving
The amount of fue l consumption, the e nviron­
men tal impact and the wear to the engine ,
b rakes and ti res depends mostly on your dr iving
s tyle. W it h an anticipatory a nd econom ic dr iv ing
style , fu el consumpt ion can be reduced by ap ­
p roxima te ly 10 -15% . The following tips will help
you conse rve the environment and you r money at
the same time .
Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra ting.
W hen you drive wi th an tic ipa tion, you do not
n eed to brake as often and so yo u ac celerate less .
When possib le, let your vehicle coast w ith a
gear
engaged ,
for example, when you notice that the
next tra ffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt io n to ze ro (fuel shut-off dur ing decelera ­
tion) .
Shift efficiently
An effective way to save f uel is to upshift earlier .
Staying in a gear too long uses fue l unnecessari­
l y .
Press down o n the acce lerator peda l s lowly and
avoid "k ic k -down".
D riving
Avoid full acceleration
Yo u should rarely travel at the maxi mum vehicle
speed. High speeds cause a disproport ionate ly
high increase i n fue l cons umption, emissions and
t raffic noise. S lowe r driving saves fue l.
Reduce idling time
The Sta rt-Stop system* helps to red uce the idling
t ime a utoma tically. In veh icles w ithout the S ta rt­
Stop system *, i t is eff icient to sw itch the engine
off when stopped at railroad crossings and long
r ed lights. Stopping the engine for 30-40 sec­
onds a lready saves more fuel than the amo unt of
extra fue l needed to restart the engine.
It ta kes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase. Therefore, you sho uld begin driving im­
med iate ly after starting the engine. Avoid h igh
RPMs wh ile doing this .
Have maintenance performed regularly
By having maintenance pe rformed regu larly on
your vehicle, you can help to reduce fuel co n­
sumption before you even start to drive. The
maintenance condition of your vehicle not o nly
affects traffic safe ty a nd long-term val ue but al­
so impa cts
fuel consumption . A poorly main­
t ai ned engi ne ca n lead t o fuel co nsump tion that
is 1 0% hig he r th an no rmal.
Avoid short trips
The eng ine and exhaust cleaning system must
r each their optima l
operating temperature to ef­
fec tively reduce consu mption a nd emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption normal izes on ly
af ter app roxima tely
2 .5 miles (4 km ).
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct press ure
r:!;> page 220. The
fuel consumpt io n can increase by 5% if the pres ­
s ur e is on ly 0 .5 bar too low. Due to t he inc reased
r oll ing resistance, low tire p ressures w ill also .,..

Driving
lead to greater tire wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra
weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph (100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting.
If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
- Have your vehicle maintained 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
could 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, switches, ignition wires,
68
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.

Automatic transmission
Introduction
The automat ic transmission is cont rolled e lec­
tron ica lly. The tra nsmission shifts up or down au­
tomatically depending on which drive program is
selected.
When a
moderat e driving style is used, the
transmission selects the most economical driving mode. The t ransmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transmission sw itches to a sporty mode a fter
a kick-down or when the driver uses a
s po rt y
driving st yle
characterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed .
If desired, the driver can also select the gears
manually ( tiptronic mode) q page 80 .
Appl ies to : ve hicles w ith S tro nic t ran smi ssio n
The 5 tronic is a dual-clutch transmiss ion . Powe r

pendently from one another. They replace the
torque converter used in conventional automat ic
transmissions and allow the vehicle to accelerate
without a noticeab le interruption in tract ion.

Check ing and F illing
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢page 192.
Octan e rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
190
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gas oline and M TBE
- Anti-knock index must be 87 AK I or h igher .
- Blend must contain not mo re than 1S% MTB E.
S easonall y adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A ma jo r concern among many auto manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu ­
facturer to ano ther, they have certain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and Filling
After an extended period of using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
(D Note
Damage or ma lf u nction due to poor fuel qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel fuel w it h concentrations of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel info rmation for e asy recog nition by
the user.
If the d iesel fue l pump is not labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be sure to check befo re t raveling to
other countries .
UL SD No . 2 can become thic ke r i n ve ry cold tem­
peratures, and th is can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
soley for use with ULSD No . 2 . Therefore,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
cove red by your New Vehicle Limited War­
r a nty.
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Imme diately contact the
