W Engine control (diesel engine )
Applies to: vehicles with diesel engines
The engine is preheating if the II indicato r light
turns on when the ignition is switched o n.
I f the indicator light does not turn on or b links
while driving , there is an eng ine control malfunc ­
tion .
Immediately drive slowly to an authori zed Aud i
dealer or authorized Aud i Serv ice Facility to have

o Malfunction indicator lamp (MIL)
The malfunction indicato r lamp (MIL) is part of
the On -Board Diagnostic System (OBD II). The Cockpit overview
('4 ,;ymbol turns on when the
ignition is switched
on and turns off again once the engine is started
and running at a steady idle speed. This indicates
that the MIL is function ing correctly.
T he indicator light turns on if there is a malfunc­
tion in the engine electronics. See an authorized
Audi dealer or authorized Audi Service Fac ility to
have the malfunction corrected . For additional
information, see

Diesel particulate filter
Applies to : vehicles wit h diesel eng ine a nd diesel particulate
filter
II Particulate filter : malfunction! See owner's
manual
T he diese l particulate filter requires regenera­
tion . To support the filter 's self-cleaning func­
tion:
Drive for approximately 15 minutes at a mini ­
mum of 37 mph (60 km/h) in 4th or 5th gear
(manua l transmission) or in the S selector lever
position (automatic transmission). Keep the en­
gine speed at approximately 2,000 RPM . The
temperature increase that will result from th is
can burn off the soot in the filter . The ind icator
light will turn off when the cleaning has complet­
ed successfully .
If the indicator light does not turn off, drive im­
med iate ly to an authori zed Audi dealer or author­
ized Audi Service Facility to have the malfunct ion
corrected .
A WARNING "---
Always adapt your speed to the current
weather, road and traffic conditions. You
should never disobey traffic laws in order to
follow driving recommendations .

Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions except for
defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .

® For the sake of the environment
-If you would like to reduce fuel consump­
t ion, sw itch the air conditioning
off. This
will also reduce emissions.
- In veh icles with a diesel engine, you can
switch the auxiliary heater
off in the Info­
tainment system.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a pudd le of water under the
vehicle . This is norma l and does not mean
there is a leak.
- The energy management system may tem­ porarily switch
off certain functions, such as
the seat heating* o r rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

Check ing and F illing
"' Position the bottle on the filler tube and turn
the bottle clockwise unti l it stops turning.
"' Press lightly aga inst the bottom of the bott le
to empty it. Continue pressing the bottom of
the bottle until it is empty or unti l fluid stops
flowing into the tank .
"' Remove the bottle and seal the filler neck
¢ page 322, Completing AdBlue refill .
0 Note
Only use refill bottles that are approved for
your vehicle. Us ing other systems can ca use
Ad Blue to leak.
-You can obta in refill bottles from an author­
i zed Audi dealer or authorized A udi Service
F ac ility.
- A pe rm itted refill bottle conta ins approxi­
mately 0 .5 gallon ( 1.9 liters) of Ad Blue.
Completing AdBlue refill
Applies to: vehicles with selective catalytic reduction
Closing the filler neck
"'Turn the Ad Blue cap to the r ight on the filler
tube unti l th e cap cl ic k s into
p lace ¢.&. in
Prepara tion on page 320,
¢ (Din Preparation
on page 320 ..
"' Then press on the left side of the tank door un-
ti l it latches.
After filling
The vehicle must be driven so tha t the system
recognizes t hat the Ad B lue was refilled. This can
t ake severa l m in utes.
"' If there was no Ad Blue left in the tank and a
r ange of O mi (0 km) was shown in the d isplay,
swi tch the ign ition on fo r abo ut 30 seconds be­
f ore star ting the engine .
(D Tips
Ad Blue in the tank can free ze at very low tem­
pera tures. If this happens, the system will
not detect that the AdB lue was refilled and it
w ill contin ue to inform you of the low AdBlue

leve l. The message tu rns off as soon as the
tank thaws out again .
Emissions control
systems
Cat alytic converter
Applies to: vehicles with gasoline engines
T he vehicle may only be driven w ith un leaded
gaso line, otherwise the catalytic converter will be
destroyed .
Never drive unti l the tan k is comp lete ly empty .
T he 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 converte r.
Di esel particulate filt er
Applies to: vehicles with diesel engines
The diese l particulate filter filters nearly all of
the soot part icles out of the exhaust. The filter
cleans itself automat ica lly under norma l dr iv ing
cond it io ns. If the filter cannot clean itself (for ex­
amp le, because yo u are on ly driving short distan ­
ces), the filter becomes clogged with soot and

_&. WARNING
The tempera ture o f the e xhaust sys tem is
h igh, both when driving and a fter stopping
the engine.
-
-Never tou ch the e xhaus t tail p ipes o nce they
have become hot. This cou ld resu lt in burns.
-D o not p ark your vehicle over flamm able
materials such as grass or leaves because
the hig h temperature of the emissions con­
trol system (catalyt ic converter or d iese l
pa rticu late filter) co uld start a fire.
- Do not apply underbody protectant in the
exhaust system area, beca use this increases
the risk of f ire.
