Diesel particulate filter
Applies to vehicles: with diesel engine
The diesel particulate fi lter fi lters nearly all of
the soot particles out of the exhaust. The fi lter
cleans itself automatically under normal driving
conditions.
If the filter cannot clean itself (for ex­
ample, because you are only driving short distan­
ces), the filter becomes clogged w ith soot and

_& WARNING
-Do not park you r vehicle over flammable
materials such as grass or leaves because
the high temperature of the diese l particu­
late fi lter could start a fire .
-
-Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or qualified repair facility. They will
adv ise you of important measures, such as corro­
sion protection, maintenance and storage proce­
dures. A lso follow the information about the bat­

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, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors :
-your personal driving style
- operating conditions
196
- technical limitations
If you ant icipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi ­
ronment and your pocketbook.
(D Tips
'
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerat ing 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
ble -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 below your car's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionate ly at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.

Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~ Shut the engine off when you are not driving
the vehicle.
~ Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automat ically reduced for
veh icles w ith the Start-Stop-System. It is effi­
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
b ur ned by sta rting the engine ag ain.
It takes a long t ime for the engine to warm up
fu lly when it is runni ng at idle . Howeve r, wear
and noxio us emiss ions a re espe cially high when
the eng ine is wa rm ing up. So you sho uld d rive
away as soon as you sta rt the engi ne and avoid
r u nning at high rpms whi le the engine is still
warming up .
(D Note
Do not leave engine id ling unatten ded a fter
starting . If warning lights should come on to
indicate im proper operation, they wou ld go
unheeded. Extended id ling a lso produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
~ Have your veh icle serviced at regu lar intervals.
By having your veh icle reg ularly serviced by an
Audi dea ler helps to ensure that it runs proper ly
and econom ica lly. The condition of your veh icle
not on ly affects its safety and ability to ho ld its
va lue, it a lso affects
fuel consumption .
Check you r oil each time you fill your tank.
The amount of oil use d i s re lated to e ngine lo ad
a nd speed.
Driving and the envir onment
It is normal for the oil consumption of a new e n­
gine to reach its lowest value after a certain mi le­
age has been dr iven.
Yo u m ust dr ive your ve hicl e abou t 3,0 00 m iles
(S, 000 kilometers) befo re yo u can properly as ­
sess oil consumption .
T h is also ap plies to f ue l cons umption and eng ine

CD Note
-Have your ve hicle maintained pro perly and
in acc ordance w ith the se rvice rec ommend a­
ti ons i n your W arra nty
& M ain ten ance book­
let . Lack of proper maintenan ce as we ll as
improper use of the ve hicl e w ill impair the
function of the em ission cont rol system and
co uld lead to damage.
- Do not alte r or remove any component of
the Emission Contro l System unless ap­
proved by the man ufacturer.
- Do not alte r or remove any device, such as
heat shields, switches, ign it ion w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System a nd othe r
im por tan t ve hicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Try to avo id driv ing short distances with a cold
eng ine .
T he engine and cata lytic conve rter have to reach
their opt imal
operating temperature to reduce
fuel consumpt io n and noxious emiss ions effec­
tively.
Just afte r starting, a cold engine in a mid-size car
only achieves a fuel economy of 6-8 m iles per
gallo n (30-40 l/ 100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . Afte r about
2 .5 m iles (4 km), the eng ine is
at its p roper operat ing temperature and fue l
eco nomy has reached a no rma l level. So yo u can
see th at yo u should avoid short trips w heneve r
poss ible. .,.

Gasoline additives
A ma jo r concern among many au to manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline gr ades d iffer from one manu ­
facturer to ano ther, they have cer tain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as f uel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i 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) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­

Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduction
In vehicles with selective catalytic reduction, a
urea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen emissions.
The Ad Blue is carried in a separate tank in the ve ­
hicle. The AdBlue usage accounts for approxi­
mately 0.5% to 2.5% of the diesel fuel that is
used.
When a message about refilling the AdBlue ap­
pears in the instrument cluster display, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility
r:!.>page 213 .
{!) Tips
-The instrument cluster display ind icates the
distance remaining that can be driven
¢ page 213. If the AdBlue tank is com­
pletely empty, the engine will not start
again after the ign ition is switched off.
- Ad Blue is required by law to operate th is ve­
hicle.

Fuel and Refueling
CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the AdBlue tank. Mixing can
lead to damage to the engine and the Ad Bl­
ue tank system .
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as poss ible with a
damp cloth and plenty of cold water . If the
Ad Blue has already crysta llized, use warm
water and a sponge. Ad Blue residue that is
not removed will crysta llize and can damage
the affected surface.
- Do not store refill bott les or canisters per­
manently in the vehicle. If the container
l eaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa­
ter.

Using the prope r engine oil is important for the
functiona lity and service life of the eng ine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year.
@ Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Maintenance booklet.
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage .
- Do not mix any lubricants or 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
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the followi ng speci­
fications.

.... M Ch eck ing and Filling
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly ove r the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
¢ page 194) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l in
the instrument cluster
II lights up, yo u should
c h eck the o il level as soon as possible

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consu Lt your Audi dealer to
have the cause of your concern properly di­
agnosed . Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
Fig. 187 I n fo tai nme nt: oil level indic a to r
• Park your vehicle on a level surface.
" Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
" Select : the
ICAR I function button > (Car)* Sys­
tems
control button > Service & control > Oil
level.
.. Check the oil level in the Infotainment system
display ¢
fig. 187. Add engine oil if the bar of
the oil level indicator is near "min"
¢page 220.
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0 .5 liter per
220
1,000 km). Consumption may be higher within
the first 3,000 miles (5,000 km).
Because of this, the engine oil level must be
checked regularly. It would be best to check each
time you refuel your vehicle and before long
drives.
{!) Tips
The oil level indicator in the instrument clus­
ter display is only an informational display. If
the oil level is too low, a minimum oil warning
appears in the instrument cluster. Add oil. If
the hood was opened, the current oil level is
shown in the instrument cluster the next time
the ignition is switched on.

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 216.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
l ubricat ing propert ies of oil d iminish gradually
during normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authorized
Audi dealer or
a qual ified service stat ion.
If y ou choo se to chan ge your oil your self , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amou nt of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
