Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
292
- Never attach any objects s uch as c upholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag canno t deploy and p rotect
properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
u pholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty

-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
-Work on the pyrotechnic circ uit interrupt ­
er must only be performed by
a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
-I f the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed .
@) For the sake of the environment
Undeployed airbag modu les a nd pretension ­
ers might be classified as Perch lorate Materi­
al
-special handling may apply, see
www.dtsc .ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requi rements a nd we recom­
mend t hat you have you r dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .
Airbag sys tem
A WARNING
-Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to prop erly restrained front sea t
occupants.

glove compa rtment.
T he knee airbag offers add itiona l protection to
the driver's and passenge r's knees and uppe r and
lower thigh areas and supp lements the protec­
tion provided by the safety be lts .

Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . Al ­
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 informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .

Selective catalytic
reduction (AdBlue/DEF)
General information
Applies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue/DE F) is injected into the
exhaust system in front of a nitrogen oxide cata­ l ytic converter to reduce nitrogen em issions. The
urea solution is known as Ad Blue or DEF (Diesel
Exhaust Flu id) . The informat ion that fo llows w ill
u se the name Ad B lue .
The Ad Blue is carried in a separate tank in the ve­
hicle. The Ad Blue usage accounts for approxi­
mately 1.0% to 4.0% of the diesel fuel that is
u sed.
When a message about refilling the AdBlue ap­ pears in the instrument cluster display, you must

Emissions control
systems
Catalytic con verter
Applies to: vehicles with gasoline engines
T he vehicle may only be driven with un leaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is compl ete ly empty .
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter .
Diesel particulate filt er
Applies to: vehicles with diesel engines
The diese l particu late filter filters near ly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under norma l driving
condit ions. If the filter cannot clean itself (for ex­
ample, because you are only driving short distan ­

- Use only a high q ual ity eng ine oil that ex-
pressly complies with the Aud i oil q uality
standard specified for your vehi cle's engine .
Using any other oil can cause serious engine
damage .
- Do not mix any l ubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa ­
b le that meets the Audi oil quality standard
your eng ine requires, you may add a total of
no more than 0.5 qt (0.5 l) of a h igh-quality
"synthet ic" o il that meets the following speci­
fications .
- Vehicles with gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W -30 or SAE 5W-40 .
- Vehicles with d iesel eng ine : ACEA C3 or
API CF with a v iscosity grade of SAE OW-30
or SAE 5W -30 .

Engine oil consumption
The engin e in your v ehicl e dep ends on an ad e­
quat e amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lub rication and cool­
ing of inte rnal engine components, all inte rnal
combustion engines consume a certain amount
of oil. Oil consumption varies from eng ine to en­
gine and may change significantly over the life of
the engine. Typ ically, engines w ith a specified
break -in period (see
c> page 86) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has stabilized .
Under normal cond itions, the rate of oil con­
sumption depends on the qua lity and viscos ity of
the oil, the RPM (revolutions per m inute) at
which the engine is operated, the amb ient tem­
perature and road condi tions. Further facto rs a re
the amo unt of oil di lution from water co ndensa­
tion or fue l resid ue a nd the oxidation level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oi l consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the y ellow engine oil leve l warning symbo l Bl
in the instrument cluster lights up, you should
check the o il level as soon as possible

venience
