- In the event of a crash with airbag deploy­
ment all locked doors will be automat ica lly
unlocked to give access to the vehicle occu­
pants from the outside.
- If the power locking system should mal­
funct ion, you can lock the driver's door us­
ing the ignit ion key

Warm and cold
Warm and cold
Climate control system
Description
Depending on the vehicle equ ipment, different
systems cou ld be installed:
- manual climate control system* or
- automatic climate control system*
The climate control system warms, coo ls and
adds humidity to the air in the vehicle interior. It
is the most effective when the windows and pan­
orama roof are closed. If there is a build-up of
heat inside the vehicle, vent ilation can help to
speed up the cooling process.
Condensat ion from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filt er
The po llutant filter removes pollutants such as
dust and po llen from the a ir .
The air pollutants filter must be changed at the intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
proper ly work.
I f you drive yo ur vehicle in an area wi th high air
pollut ion, the filter may need to be changed
more frequently than specified in your Audi War ­
ranty & Maintenance booklet. If in doubt, ask
your author iz ed Audi Service Advisor for advice.
K ey rec ognition *
The deluxe automati c climate control* settings
are stored and assigned to the remote contro l
key that is in use .
A WARNING
Reduced visibility is dangerous and can ca use
accidents.
62
- For safe driving it is very important that all
w indows be free of ice, snow and condensa­
tion.
- Complete ly familiarize yourself with the
proper use and function of the heating and
ventilation system and espec ially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­
ing and vent ilation system . The washe r so lu­
tion may freeze o n the windshield and re­
duce visibility.
(U;) Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid furthe r damage a nd have it inspected
by a q ualified deale rship .
- Repa irs to the Aud i ai r cond itione r requ ire
special techn ica l know ledge and spec ial
tools. Contact an authorized Audi dea le r fo r
assistance .
@ For the sake of the environment
By reducing t he amo unt of fuel you use, you
a lso red uce the amount of pollutan ts emitted
i nto the a ir.
(D Tips
- To prevent i nterference with the heating
and cooling ou tput and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- The energy management system may switch
t h e seat heating * or rear window defroster
o ff temporarily. These systems are available
again as soon as the energy supply has been
restored.

Automatic transmissio n
Automatic transmission
tiptronic
Introduction
The automat ic transmission is controlled e lec­
tron ically . The transmission upshifts or down­
shifts automatically depending on wh ich dr ive
p rogram is selected.
When a
m oderate dri ving style is used, the
transmission se lects the most e conomical d riving
mode. The t ransm iss ion upshifts a t a lower RPM
and downshifts at a higher RPM to imp rove fuel
efficiency.
The transm ission switches to a spo rty mode afte r
a kick-down or when the drive r uses a
sport y
d riving sty le
charac ter ized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can a lso select the gears
manually (tiptronic mod e) ¢ page 85.
In the tiptronic t ransmiss ion, power is trans fer­
red by a torque converte r.

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 kilometer s):
"' 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 pe rm issib le road or engine speed .
During and after break-in pe riod
"' 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 c ircumstances .
"'U pshift into the nex t higher gear
before reach­
ing the red area a t the end of the tachometer
sca le
c=> page 10.
During the first few hours of driving, the eng ine's
internal fric tion is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).
(D Note
Extremely high eng ine speeds a re au toma ti­
cally reduced . However, these rpm limits are
programme d for a n engine well run-in, not a
new engine.

Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
WARNING
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking .
Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem
parts do no t bottom o ut and get dama ged.
T his is espec ially true for ve hicles with low-s lung
c h ass is (sports c hass is) * and fully loaded
vehicles.
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 an
environmentally sound manner.
"' Always use lead -free gasoline c> page 173,
Fuel supply.
"' Never run the tank down all the way to empty.
"' Never put too much moto r o il in you r engine
c=> page 181, "t':::r. Adding engine oil .
"'Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean-up" device built into the exhaust system of the veh i­
cle. The catalyt ic converter b urns ma ny of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere .
The exclusive use of un leaded fuel is critically im­
portant for the life of the catalytic converter and
prope r fu nct ion ing of the eng ine. ..,.
159

Driving and th e en vironm ent
A WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot . This could result in burns.
- Do no t park or operate the vehi cle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used for undercoating could ove rheat and
ca use a fire .
(D Note
-Be aware that just one tank filling with
leaded fuel will a lready ser iously degrade
the performance of the catalytic converter .
- Do not exceed the correct eng ine oi l level
¢ page 181.
-Do not drive until the fuel tank becomes
complete ly empty. The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause t he
catalytic converte r to overheat.
- Do not turn off the ignition whi le the vehicle
i s mov ing.
- Do not continue to operate your veh icle un­
der these cond itions, as otherwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in ove rheating of t he converte r, req uir ­
i ng its re placement.
- T o assure efficient operation of the Emis­
s ion Control System:
- Have your ve hicle maintained properly and
in accordance with the se rvice recommen ­
dations in your Wa rranty
& Maintenance
book let .
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission cont rol system
and co uld lead to damage.

-
® For the sake of the environment
Even when the Emiss ion Control System is op­
e rating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op­
erating states. T his depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer pe riod of time, contact an Audi
o r othe r spec ia liz ed dealer. They ca n adv ise you
o n necessa ry p recautions e.g. corros io n preven­
tion, m aintenance and storage . Pay attention to

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, a s well as exhau st and
noise levels .
Fu el economy, env ironmenta l impact, and wear
o n your e ngine, brakes and tires large ly depend
o n t hree fa ctors:
- your personal d riving style
- operat ing cond itions
- technical limitat ions
If you anticipate what you need to do next and
drive economically, you can easily cut your f uel
consumption by 10-lS percent. Th is sect ion wi ll
give you some tips on how you can help the envi­
ronment and your pocketbook .
{l) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTIO N AGENCY
(EPA) and T ransport Canada may not corre­
spond to your actual consump tion on the
r oad, which wi ll vary depending upon vehicle
l oad and speed, road a nd wea ther conditions,
tri p l engt h, etc.

Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating .
11-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 vehicle coast whenever possi­
ble - for example when you see that the next traf ­
f ic light is red .
Avoid full throttle
Driving a t modera te speeds saves fuel and im­
proves your mileage .
11-Try and keep well be low your car's max imum
speed.
Accelerating gent ly reduces fuel consumption,
engine wear, and does not disturb the environ ­
ment.
F ue l cons umption, exha ust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumpt ion will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.
Reducing unnecessary idling
Even when your car is just idling i t burns up fuel.
11-S hut the engine off w hen you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the en-
gine ru n at idle .
It makes sense to shut off the eng ine in traffic
jams, when wa iting for trains to pass at rai lroad
crossings, or at traffic lights that have long waits
on red . Turn ing the eng ine off for just 30 -40 sec ­
onds saves more fue l than is bu rned starting the
engine agai n.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . However, wear
and noxious emiss ions are especially high when
the eng ine is wa rm ing up . So you should d rive
Driving and the envir onment
away as soon as you start the eng ine and avoid
running at high rpms w hil e the engine is sti ll
warming up .
(D Note
Do not leave eng ine idling una ttended after
starting. If wa rning lights shou ld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also prod uces
heat, which could result in overheating or
other damage to the vehicle or other proper ­
ty .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
11-Have your vehicle serviced at regular interva ls.
By having your vehicle regular ly serv iced by an
authorized Audi dea ler helps to ensure that it
runs properly and economically. The cond ition of
your vehicle not only affects its safety and ability
to hold its value, it also affects
fuel con sump­
tion .
Chec k your oil each t ime you fill your tank.
T he amount o f oi l used is related to engine load
and speed.
It is normal fo r the oil consump tion of a new en­
gine to reach its lowest value after a ce rtain m ile­
age has been dr iven.
You m ust dr ive your ve hicle about 3,000 m iles
(5,000 kilometers) befo re yo u can prope rly as­
sess oil consumpt io n.
T h is also app lies to fuel consumption and eng ine
output.
(D Note
- Have your vehicle maintained properly and in accordance with the se rvice recommenda­
tions i n your Warranty
& M aintenance book-
le t. La ck of prope r maintenan ce as we ll as
imp roper use of the ve hicle will im pair the
function of the em ission cont rol sys tem and
co uld lead to damage . .,.
161

Driving and th e en vironm ent
- 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 shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Em ission Control System and other
i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on shor t trips.
... Try to avoid driving short distances with a cold
engine.
The engine and catalyt ic converter have to reach
their optimal
ope rating temperature to reduce
fue l cons umption and nox ious emissions effec­
tively .
J ust after starting, a co ld eng ine in a m id -s ize ca r
only achieves a f uel economy of 6-8 miles p er
ga llon (30 -40 l/100 km). After about a half a
mile ; fu e l economy cl imbs to 12 mpg (20 l/100
km). After about
2.5 miles (4 km), the engine is
at its prope r operating temperature and fuel
economy has reached a normal level. So you can
see that you sho uld avoid short t rips whenever
possible.
The
outsid e temperature is also critical in this re ­
gard . Your car consumes more fuel in the w in ter
than in the summe r.
Driving offroad
General information
When driving offroad, the f unctions for the elec­
tron ic stabili zation control (ESC) are expanded.
ESC offroad mode can be activated in dr iving sit­
uations in which a whee l lock o r a d ifferent ial
lock fu nction is needed
r=.> page 152.
However, your Audi is not an offroad vehicle.
Never drive the vehicl e in terra in which is not
suitabl e for the vehicle, or which exceeds your
driving skills. Never take any unnecessary ri sks!
162
After driving offroad
- After driving off road, remove branche s and
other deb ris from the rad iator g rille, under ­
body, and w heels . Look especially fo r objects
(stones) that have been caught in the tire
tread.
- Clean the body and the ve hicle unde rbody and
i nspect the ve hicle for possible damages.
- Clean off the dirty windows, headlights, tail
lights and t he license plate.
- Per form a brake test (especia lly after d riving
throug h water) .
A WARNING
-Be especially aware and attentive when d riv ­
ing under diff icu lt cond itions. Damages to
the vehicle and injur ies may occur when
driving at an excess ively high speed o r with
incor rect d riving maneuvers .
- Always ad just yo ur speed and handling to
the roads, terra in, traffic and weathe r con ­
d itions . D rive especially s low if offroad wi th
low visibility.
- Please note that t he wheels can sp in mo re
and the vehicle can swerve when in ESC off­
road mode , espe cially when the road is slip­
pe ry o r has loose surfa ce m aterial.
- Driv ing stability is reduce d in the ESC

Fuel and Refueling
Gasoline
Fuel supply
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
in formation 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 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 minimum octane rat­
ing of 87 AKI/91 RON. However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine pe r­
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 gasoline may not be available.
For more information on refueling your vehicle,
see
r=;, page 17 4.
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
help prevent poss ible 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:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 - 90 AKI
Fuel and Refueling
Explanation of the abbreviations :
AKI=
Ant i Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Re search Octane Number
MON= Motor 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 w ill occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline b lended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure meets the follo wing
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 AKI 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-ove r, we suggest that you
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time. ..,.
173

Fuel and Refueling
CJ) 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 a re not the respon­
s ibilit y 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 prob lems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
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 vita l engine
