198 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 r=;, page 210,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
r=;, page 223, 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
r=;, page 223.
-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

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.
Diesel particulate filter
Applies to vehicles: with d iesel eng ine
The diesel particulate filter fi lters nearly a ll of
the soot part icles out of the exhaust. The fil­
ter cleans itse lf automatically under normal
driving conditions. If the filter cannot clea n it­
self (for examp le, because you are only driving
short d istances) , the fil ter becomes clogged
with soot and the
II symbo l for the diesel
particulate f ilter illum inates ~ page 23.
A WARNING
- Do not park yo ur vehicle ove r flammable
materials such as g rass or leaves because
the high temperature of the diesel par­
t icu late filter could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could
start.
Dri ving and the en vironm ent 199
Placing your vehicle
out of service
If you would like to take your vehicle out of
se rv ice for a longer time, contact your author­
ized Audi dealer or qualified repair fac ility .
They w ill advise yo u of impo rtant measures,
such as corrosion p rotection , maintenance
and storage p roced ures. Also follow the infor­
ma tion about the battery ~ page 228 .
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 .
Fuel economy, env ironme ntal impact, and
wea r on your eng ine, b rakes and tires la rgely
depend on three factors:
- your personal d riving s tyle
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you 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 t he env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTECTION AGENCY
(EPA) and Transpo rt Canada may not corre­
spond to your actual consumption on the r oad, which will va ry depending upon vehi ­
cle load and speed, ro ad and weather con­
ditions, trip leng th, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating .

-Do not alter or remove any component of
the Emission Contro l System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System and other important veh icle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
~ Try to avoid driving short distances with a
cold eng ine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
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 m iles (4 km),
the engine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips wheneve r possible.
The
outside temperature is also critical in this
regard . Your car consumes more fuel in the
winter than in the summer.

210 Checking and Filling
Checking and Filling
Gasoline
Fuel supply
Applies to vehicles: with gasoline engine
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline . Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of91 AKI (95
RON) . For more information on TOP TIER De ­
tergent Gasol ine, please go to the official
website (www .toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the ins ide of the fuel filler flap. This rat­
ing may be specified as AKI or RON .
Your vehicle may also be operated using un­
leaded regular gasoline with a minimum oc ­
tane rating of 87 AKI/91 RON . However, using
87 AKI/91 RON octane fuel w ill slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see
~ page 212.
Octane rating
Octane rating ind icates a gasoline's ability to
res ist engine damaging "knock" caused by
premature ign ition and detonation . Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane
r atings that can usually be found on the filler
pump : - Premium Grade: 91
-96 AKI
- Regular Grade: 87 -90 AKI
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 any fuel w ith octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will severely damage
your vehicle'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
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AK I or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must not contain more than 15%
ethanol.
Blend of gasoline and MTBE
-Anti-knoc k index must be 87 AK I or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline

212 Checking and Fill in g
- If you put any amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed.
- If the diesel fuel quality is poor, it may
be necessary to have the water drained
from the water sepa rator in the
f ue l fi l­
te r
more often than specified in the
maintenance schedu le . This can help re­
duce engine ma lfunctions

Your veh icle fuel tank has an onboard refue l­
ling vapor recovery system . This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protect ing the env ironment,
p lease follow t his refueling procedure careful­
ly.
.&_ WARNING
Under norma l operating conditions, neve r
carry additiona l fuel containers in your car .
Gas can isters and other containers used to
transport fue l can be dangerous. Such con­
tainers, full or empty, may leak and cou ld
cause a f ire in a collision. If you must transpo
rt fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe local and state laws regard­ ing the use, transportation and storage of
such fuel containers. Make certa in the con­
tainer meets industry standa rds (ANSI/
ASTM F8S2 -86).
(D Note
Neve r drive your veh icle until the fue l tank
i s completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

Selective catalytic reduction
General information
Applies to vehicles: with diesel e ngine
In vehicles with se lective cata lytic reduction, a
urea solut ion (Ad Blue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen -emissions .
Ad Blue is the marketing name for Diese l Ex­
ha ust Fluid (DEF) .
The AdBlue is carried in a separa te tank in t he
vehicle . The AdBl ue usage accounts for ap­
proximately 0.5% to 1.2% of the diese l fuel
that is used .
When a message abo ut refil ling the Ad Blue
appears in the inst rume nt cl uste r dis play, you
must refi ll the Ad B lue yourse lf or have it refil­
l ed by an authorized Audi dealer or aut horized
Aud i Service Facility
Q page 216.
A WARNING
Failure to heed Ad Blue refill information in
the inst rume nt cluste r can p revent the
ve­
hicle from being started and driven . If the
veh icle cannot be driven and an eme rgency
ar ises, perso na l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank r uns d ry.
(!) Tips
- The instrument cluster display indicates
