Driving
General information
The first 1,000 miles (1,500 km) and
afterwards
The new engine needs to be run-in during the
first 1,000 miles (1,500 km) .
For the first 600 miles (1 ,000 k ilometers ):
.. Do not use full throttle.
.. Do not drive at engine speeds that are more
than 2/3 of the maximum permitted RPM .
.. Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to
1,500 kilometers):
.. Speeds ca n gradually be increased to the maxi­
mum perm issible road or eng ine 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 peri od
.. Do not exceed maximum engine speed under
any circumstances.
.. Upshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
opage 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break-in process is done depends to a cons idera­
b le extent on the way the vehicle is driven dur ing
the first 1,000 miles (1,500 kilometers).
0 Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
programmed for an engine well 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 through water on roads
Note the following to avoid veh icle damage when
driving through water, for example on flooded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not dr ive faster than walk ing speed .
A WARNING
After driv ing through water or mud, the brak­
ing effect can be reduced due to moisture on
the brake discs and bra ke pads. A few careful
brake applications sho uld dry off the brakes .
(D Note
Vehicle components such as the eng ine,
transmission, suspension or electrical system
can be severe ly damaged by driv ing through
water .
(D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driv ing th rough
water .
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driving through salt wate r (corrosion).
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.
Fuel economy, env ironmental 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 w hat you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. Th is sect ion will
g ive you some tips on how you can help the envi­
ronment and your pocketbook.
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depend ing upon vehicle load and
speed, road and weather conditions, trip
length, e tc.
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 vehicle coast whenever possi­ b le -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 be low your car's max imum
speed .
Accelerating gently reduces fuel consumpt ion,
engine wear, and does not d isturb the env iron­
ment .
Fue l consumption, exha ust emissions and eng ine
noise increase disproportionately at high speeds.
If you drive at approx imately t hree quarters of
top speed, fuel consumpt ion w ill be reduced by
one half . Never dr ive faste r than the posted
speed limit a nd weather conditions perm it.
Dri ving
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 lett ing the en-
gine run at idle.
It is efficient to switch off the engine when stop­
ped at ra ilroad crossings and long red lights.
Turning the engine off for just 30-40 seconds
saves more fuel than is b urned by starti ng the
engine aga in .
It takes a long t ime for the engine to warm up
fully when it is ru nning at idle. However, wear
and noxious emissions are espec ia lly hig h when
t h e engine is warming up. So you should d rive
away as soon as you sta rt the eng ine and avoid
run ning at high rpms w hile the eng ine is s till
warmi ng up .
@ Note
Do no t leave eng ine idl ing una ttended afte r
s ta rtin g.
If war ning lig hts s hou ld come on to
i ndica te imprope r operat ion, they would go
u nheede d. Extended idling also produces
heat, which could result in overheat ing or oth­
er damage to the ve hicle or other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.. Have your ve hicle serviced at reg ular in tervals.
B y havi ng your ve hicle regu la rly se rv iced by an
Audi dealer he lps to ensu re that it ru ns p rope rly
and economically. The condi tion of your veh icle
not only affects its sa fety and ability to ho ld i ts
val ue, it also affects
fuel consumption.
Check your oil each time you fill your tank.
The amou nt of oi l used is re lated to engine load
and speed.
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certai n m ile-
age has been dr iven. ...,
71

Driving
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly as­
sess oil consumption.
This also applies to fuel consumption and engine
output.
@ Note
- Have your vehicle maintained properly and
in accordance w ith 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 ap­proved by the manufacturer.
- Do not alter or remove any device, such as heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
.,. Try to avoid driving short distances with a cold
engine.
The eng ine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively .
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 miles (4 km), the en­
gine is at its proper operating temperature and
fuel economy has reached a normal level. So you
can see that you should avoid short trips whenev­
er possible.
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back .

A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the
vehicle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches (25 cm) dis­
tance between your chest and the steering
wheel ¢
page 131, fig. 113. If you do not
maintain this distance, the airbag system
will not be able to provide its full protection
¢page 131, fig. 113.
-If your physical characteristics prevent you
from sitting at least 10 inches (25 cm) or
more away from the steering wheel, see if
your authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision . Always make sure
that the steering wheel is level with your
chest .

Automatic transmi ssion
Automatic transmission
S tronic
Introduction
Applies to veh icles: w ith S tro nic transmiss ion
Your vehicle is equ ipped w ith an electronically­
contro lled DSG transmission ca lled S tronic. Two
independent clutches transfer the power be­
tween the eng ine and t ransmission. It a llows the
vehicle to accelerate without a noticeable inter ­
ruption in tract ion .
The transmission upshifts or downsh ifts auto­
matica lly. The driv ing style contin uously influen­
ces the se lection of the driving program .
When a
mod era te driving style is used, the
transmiss ion se lects the mos t econom ica l driving
mode. The transmission upsh ifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transmission swit ches to a sporty mode after
a kick-down or when the driver uses a
s po rty driv­
ing sty le
characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed and t raveling at the maximum
speed.
If desired, the drive r can a lso se lect the gears
manually ( tiptronic mode) ¢ page 87, Shift ing

Checking and F ill in g
Checking and Filling
Gasoline
Fuel supply
App lies to veh icles: w ith gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel re co mm en da tion
The fuel recommended for your vehicle is unl ead­
e d prem ium
grade gaso line. 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 ins ide of the fuel filler flap . This rating
may be specified as AKI or RON .
Your vehicle may also be operated using unlead­
ed regular gasol ine with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/
91 RON octane fue l wi ll sli ght ly reduce engine
pe rformance.
U se un leade d ga solin e only . Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not ta ke you r vehicle to areas or countr ies
where unleaded gasoline may no t be ava ilable.
For more informat ion on refueling your veh icle,
see
¢page 192.
Octan e rat ing
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation . Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine 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:
- Prem ium Grade : 91 - 96 AKI
190
- Regular Grade: 87 -90 AKI
Explanation of the abb reviations:
AKI = Anti Knock Index = (R +M)/2 = (RON+MON)/
2
RON= Research Octane Number
MON = Motor Octane Number.
{[) Note
-Do not use any fue l w ith o ctane rat ings 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 veh i­
cle's catalytic converter and its abi lity to
control exha ust em issions.
Blended gasoline
App lies to vehicles: wit h gaso line e ngi ne
U se of g aso lin e cont aining alcohol or MTBE
( meth yl tert iary butyl ethe r)
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen­
ates) if the ble nded mixture meets the following
criteria:
Blend of gasoline methano l (wood alcohol or
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 solin e and ethan ol (grain alcoh ol or
ethyl alcohol )
- Anti-knock index must be 87 AKI or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of ga soline a nd M TBE
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain not more tha n 1S % MTB E.
S eas onall y adjust ed 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 tha t you .,..

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
(D Note
- Methanol f uels 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 fue ls that fail to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whethe r o r
not a particular fue l 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 fue ls differ­
ent from those specified are not the respon­
s ibility 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 b lends, we
recommend that you sw itch to unb lended
fuel.
Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common . All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
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 off icial webs ite

After an extended period o f using inadeq uate
fuels, carbon deposit build-ups can rob your en­ gine of peak performance .
(D Note
Damage or malf u nction due to poor fuel qual ­
ity is not cove red by the Audi New Vehicle
Limited Wa rranty.
Diesel fuel
Applies to vehicles: with diesel engine
Always use ULSD (Ultra Low Su lfur Diesel) No. 2 .
The ULSD No. 2 meets the ASTM 0975.
Diesel fuel w ith concen tra tions of biodiese l hig h­
er than 5
% such as Bl 1, B20 or 8100 are strictly
prohibited .
Se rv ice stat io n fue l pumps a re labe led with the
correct fue l information for easy recognit ion by
the user .
If the diese l fue l pump is not labe led
ask the station operator w hat fue l is being dis­
pensed before fi lling up your vehicle.
UL SD No. 2 may not be available outside the USA
and Canada . Be sure to check before traveling to
other countr ies .
UL SD No. 2 can become thicke r in very cold tem­
pera tures, and th is can impa ir t he engine's start­
ing and running. Depending on the season, 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
- Yo ur vehicle's diesel engine was designed
soley for use with ULSD No. 2. Therefore,
never use gasoline, heating oil, other fuels
or flow improvers. These conta in substances
that will severe ly damage the fuel system
and the engine . Such damage will not be
covered by you r New Veh icle Limited War­
ranty.
- If you put any amount of incorrect fuel i n
the fuel tank, do not start the eng ine under
any circumstances. Immediate ly co ntact t he
nearest authori zed Aud i dealer or autho r­
ized Aud i Service Fac ility for assistance .

Checking and Fill in g
These fuels contain substances that can se ­
verely damage the fuel system and the en­
gine if the engine is started .
- If the diesel f uel quality is poor, it may be
necessary to have the water d rained from
the water separator in the
fuel filter more
often than specified in the maintenance
schedule. This can help reduce engine ma l­
funct ions

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious burns and other injuries.
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and start a fire.
- Do no t use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling . If
you must make an exception and enter your
vehicle again while fueling , close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident .
-If you must make an exception and trans­
port a fuel container, note the following:
Checking and Filling
- Never fill the fuel container with fuel
while it is in or on the vehicle . Static elec­
tricity is discharged when filling which can cause the fuel vapors to ignite and increas­
es the risk of an explosion .
- Always place a fuel container on the
ground before filling .
- Always hold the fuel nozzle completely in
the fuel container when filling .
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This prevents static electricity from discharg­
ing .
- Never spill fuel in the vehicle or the lug ­
gage compartment . Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death.
- Follow legal requirements when using,
storing and transporting fuel containers .
- Make sure the fuel container conforms to
industry standards (ANSI/ASTM F852-86).
Q) Note
-Remove spilled fuel from vehicle paint im­
mediately , because it can damage paint .
- Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires .
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
- If the fuel tank runs completely empty in a
vehicle with a
diesel engine, the ignition
must remain switched on for at least 30
seconds after refueling before starting the
engine. It may take longer than usual for
the engine to start, even up to a minute.
This is because the air must first bleed out of the fuel system when starting the engine .
@ For the sake of the environment
- If
the fuel nozzle is used correctly, it will in­
dicate that the tank is full the first time it
switches off automatically. Do not try to add
more fuel, because it can spill over. Also, "'
