,. Always distribute the loads on the roof rack
evenly .
,. Always attach items to the roof rack securely
before you d rive off.
The maximum perm iss ible roof we ight is
165 lb (75 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You m ust also
not exceed the maximum load weight for the
roof rack you are using.
When us ing a roof rack system which has a
l owe r load carry ing capac ity, you must not use
up the total max imum pe rm issib le load carry ­
i ng capac ity specified above. Instead, you
should load the roof rack system only to the
maximum capacity specified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause se rious personal injury .
- Make sure the roof rack is insta lled exact­
ly as specified above¢

Automatic
transmission S tronic-transmission
Introduction
Applies to vehicles: with S tronic transmiss ion
Your vehicle is equipped with an electronical­
l y -controlled DSG transmission called S tronic.
T wo independent clutches transfer the power
between the engine and transmission. It al­
lows the vehicle to accelerate without a no­
ticeable interruption in traction .
T he transmission upshifts or downshifts auto­
matically. The driving style continuously influ­
ences the selection of the driving program .
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. The transmission upshifts at a
lower RPM and downshifts at a higher RPM to
improve fuel effic iency .
T he transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) r=> page 110,
Shifting manually (tiptronic mode) .
Selector lever positions
Applies to vehicles: with S tro nic transmission

r=> &. .
To select the R selector lever position, press
the interlock button
while press ing the brake
pedal. The back-up lights sw itch on in the R
pos ition if the ignition is switched on .
N -Neutral
The transm iss ion is in idle in this position .
DIS -Normal position for driving forward
In the D/S selector lever position , the trans ­
mission can be operated either in the normal
D mode or in the S sport mode. To select the S
spor t mode, pull the selector lever back brief­
ly. Pulling the lever back again will select the
normal D mode . The instrument cluster dis­
play 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 driv­
ing style .

194 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, 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 vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
> Always use lead-free gaso line¢ page 206,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
¢ page 215, Adding engine oil > Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- Never touch the exhaust tail pipes once
they have become hot . This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢page 215.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel
IIJ,,

can reach the catalytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service.
I f you wou ld like to take your vehicle out of
service for a longer t ime, contact your aut hor­
iz ed A udi dealer or qualified repair facility .
They will advise you o f important meas ures,
such as cor rosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery¢
page 220.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle , as well as ex­
haust and noise levels.
F ue l economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors:
Dri ving and the en vironm ent 195
-your personal d riving s tyle
- operati ng conditions
- technical limitat io ns
If you ant ic ipate what you need to do next and
drive econom ically , yo u can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
(D Tips
The consumption estimates as published
by ENVIRO NM EN TAL PROT ECTI ON AG ENC Y
( E PA) and Transpo rt Canada may no t cor re­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id u nnecessary accelerating and brak ing.
Vehicles use the mos t fu e l when they are ac­
ce lerating. If you anticipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce le rat ing gently re duces fue l cons ump ­
tion, eng ine wear, and does not disturb the
environment .
Fuel consumpt ion, exhaust em iss ions an d en­
gine noise inc rease disproportionate ly at high
speeds . If you drive at approximately three
quarte rs of top speed, fuel consumption wi ll
be reduced by one ha lf. Never drive faster

than the posted speed limit and weather con­
ditions permit.
Reducing unnecessary idling
Even wh en your car is just idling it burns up
fuel.
,.. Shu t the engine off when you a re not dr iv ing
the vehi cle.
... Do not warm up the vehicle by letting the
engine run at idle.
It is efficien t to switch off the engine when
stopped at railroad crossings and long red
lights. Turning the engine
off for j ust 30-40
seconds saves mo re f uel than is burned by
start ing the engine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid ru nning at h igh rpms while the engine is
still warming up.
{[) Note
Do not leave engine idling unattended af­
ter starting. If warning lights s hould come
on to indicate improper operation, they
wou ld go unheeded . E xtended idling also
produces heat, which cou ld resu lt in over­
heat ing or o ther da mage to the vehicle or
o ther prope rty.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
H aving your vehicle regular ly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . T he condition
of yo ur vehicle not only affects its safety and
ab ility to hold its value, it also affec ts
fuel
con sumption. Check
your oil each t ime you fill your tank.
T he amou nt of oi l used is re lated to engine
lo ad a nd speed.
It is normal fo r the oil consumption of a new
engine to reach its lowest valu e after a c erta in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt io n.
This also app lies to fue l consumption and en­
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
