The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- 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 which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
f uel will a lready se riously degrade the
performance of the c ata lytic conver ter.
- Do not exceed the co rrect engine oil leve l
9page203.
-Do not d rive until the fuel tank becomes
complete ly empty. The eng ine could misfi re.
U nburned f uel co uld also ge t in to the e x­
haust system and this could ca use the cata ­
l ytic converter to overheat.
- Do no t sw itch off the ignition wh ile the vehi­
cle is moving.
- Do not con tinue to oper ate yo ur vehicle un­
der these cond itions, as o therwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.
- To assure efficient ope ration of the Emission
Control System:
Checking and Fillin g
- Have your vehicle maintained properly and
in accordance with the serv ice recommen­
dat ions in yo ur Warranty
& Maintenance
booklet.
- Lack of prope r maintenance as we ll as im­
p roper use of the vehicle will impair the
f u nction of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exha ust gas can have a
su lfur-like exhaust gas sme ll under some op­
erating states. Th is depends on the s ulfur
content of the fuel b eing used. Us ing a diffe r­
ent bra nd of fue l may he lp, or fi lling the tank
wi th lead-free su per grade gaso line.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
T he diese l part icu late filter filters nearly all of
the soot pa rticles ou t of the exha ust. The filter
cl ea ns itself a utoma tic all y unde r no rm al driving
con dit ions. If the filte r cannot clean itse lf (for ex­
amp le, because yo u are only driving sho rt distan ­
ces), th e fi lter becomes clogged with soot and
the
II symbol for the diese l partic ulate filter il­
l uminates
9page 22.
A WARNING
-Do not park your veh icle over flammable
materials such as grass or leaves because
the high temperature of the diesel part icu­
la te filte r could sta rt a fi re.
-
- Do not app ly an underbody protectant in the
exhaust system area or a fire cou ld start.
Selective catalytic
reduction
General information
App lies to vehicles: wit h diese l eng ine
In veh icles with selective catalytic reduction, a
u rea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
conve rter to redu ce nitrogen emissions.
195

Checking and Fill in g
Ad Blue is the market ing name for Diese l Exhaust
Fl uid (DEF) .
The AdBlue is carried in a separate tank in the ve ­
h icle. The AdB lue usage acco unts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used .
When a message about refil ling the Ad Blue ap­
pea rs in the instrument cluster disp lay, yo u must
refill the AdBlue yourself or have it refilled by an
authorized Aud i dealer or authorized Audi Se rvice
Facility ¢
page 197 .
A WARNING
Failure to heed Ad Blue refill information in
the instrument cluster can prevent the vehicle
from be ing started and driven. If the veh icle
cannot be driven and an emergency arises,
personal in ju ry can occur.
-Always have the Ad Blue tank refilled well before the tank runs d ry.
(D Tips
-
- The instrument cluster display indicates the
distance remaining that can be driven
¢ page 196. If the AdBlue tank is com ­
plete ly empty, the engine w ill not start
again after the ig nition is switched off.
