climate control
Description
The climate con trol system warms, coo ls and re ­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed. If there is a bu ild-up of heat
i n side the veh icle, ven tilat ion can he lp to speed
up the cooling process .
In a ll heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filt er
The po llutant filter removes pollutants such as
d ust and pollen from the air.
Key recognition
The clima te control settings are automatically
s tored and assig ned to th e remo te contro l key
that is in use.
& WARNING
Poo r visibility can lead to accidents.
- For safer d riving, keep all windows free of
ice, snow and fo g.
- B ecome familia r as quickly as possible wi th
the correct use and function of the cl imate
contro l system, especially with the defrost­
ing and defogging function.
- When the temperat ure is below freezing,
only use the windsh ield washer system after
Warm and cold
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visib ili­
ty .
(D Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Aud i dealer o r authorized
Aud i Serv ice Facility.
- Repa irs to the Aud i climate control system
require special technical know ledge and
special tools . See an autho rized Aud i dea le r
or authorized Audi Service Fac ility.
@ For the sake of the environment
Reducing the amount of fuel used also re ­
duces the amount of pollu tan ts that enter the
ai r.
@ Tips
- To prevent interference with the heat ing
and coo lin g output and to prevent the wi n­
dows from fogging over , the air intake in

Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at the same time .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine .
It takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

Automatic transmission
Introduction
The automat ic transmission is cont rolled e lec­
tron ica lly . Power is transferred using a torque
converter.
The transm ission shifts up or down a utomat ica lly
depending on w hich drive program is sele cted.
When a
moderate driving style is used , the
transmission selects the most economical d riving
mode. The t ransm iss ion upsh ifts at a lowe r RPM
a nd downshifts at a highe r RPM to imp rove fuel
effi ciency .
The transm ission sw itches to a spo rty mode after
a ki ck-down or when the drive r uses a
sporty
driving style
c haracterized by quick accelerator
pedal movements, heavy acce leration , freq uent
changes in speed and traveling at the maximum
speed.
If desired , the dr iver can also select the gears
manually (tiptronic mode)

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 .
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
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,
please go to the official website
(www.toptiergas .com) .
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a min imum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKl/91
RON octane fuel will slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gasol ine may not be available.
For more information on refueling your vehicle,
see
~ page 268.
Octane 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
h e lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat-
~ ings that can usually be found on the filler pump: .... N
~ -Premium Grade: 91 -96 AKI .... 0 0 :c ' Checking and Filling
-Regu lar Grade: 87 -90 AK I
Exp lanation of the abbreviations:
AK I=
Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Moto r Octane Number.
(D Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not us e leaded gasoline. The use of lead­
ed gasoline will severe ly damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AK I or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iving . Dur-
ing seasonal change-over, we suggest that you ..,.
267

Checking and Filling
fill up at busy gas stations where the seasonal
adjustment is more likely to be mad e in time.
0 Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail 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 identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A pp lies to: ve hicles w ith gasoline engine
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use .
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
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 information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
268
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.
([) Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.
Refueling
· Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
~ page 2 70.
You can find the fuel tank capacity of your vehicle
in
~ page 334 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 267.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
& WARNING
-Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/AS TM F8S2 -86).
