-Sunglasses w ith polarization fi lters and un ­
favorable lighting conditions can have a negative effect on the display.
- An optimum display depends on the seat
position and the height adjustment of the
head-up display.
- A specia l windshield is needed for the head­
up display function.

On-Board Diagnostic
System (OBD)
Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) ¢'4 in the
instrument cluster is part of the On-Board Diag­
nostic System (OBD II).
The indicator light turns on when the ignition is
switched on and turns off once the engine is
started and is running in idle at a stable speed.
This indicates that the MIL is functioning correct­
ly .
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a malfunction in the engine. If the indicator turns on, the catalytic converter may be
damaged .
Drive
with reduced engine performance (avoid
high speeds for extended periods of time and/or
fast acceleration) and have the malfunction cor­
rected. See an authorized Audi dealer or author ­
ized Audi Service Fac ility .
The electronic speed limiter may be faulty if the
indicator light turns on . For additional informa­
tion, see¢
page 102, Electronic speed limiter .
The MIL indicator light may also turn on if the
fuel filler cap is not closed correctly

Cockpit overview
On-Board Diagnostics
Fig. 19 Locatio n of Data Li nk Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed (only vehicles with gasoline engine)
<=>page 316 .
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip­
ment, push the plug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig . 19 .
Your authorized Aud i dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING ~ ~ ·
Do not use the diagnostic connector for per-
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

Fuel filler neck
The fuel fille r neck is located on the right rear
s ide pan el behind the fu el filler flap .
I f the power locking system should fail, you can
still open the flap manua lly -for detai led instruc­
tions see
c::> page 318.
You can find the fuel tank capac ity of you r vehicle
in

The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle . For more in­
formation about fue l specifications , see
c::> page 314 .
Your veh icle fuel tank has an onboard refuelling
vapor recovery system . This feature he lps to pre­
ve nt fuel vapors from escap ing from the tank and
pollut ing the e nvironment while yo u re fuel your
veh icle. In order to fi ll the tank properly while
protecting the environment, please fo llow this
r e fu eling procedure carefu lly.
& WARNING
Under normal operating conditions, never car­
ry additiona l fuel containers in yo ur car. Gas
canisters and other conta iners used to trans­
port fuel can be dangerous . S uch containers,
full or empty , may lea k and could cause a fire
in a collision. If yo u m ust t ransport fue l to
use for yo ur lawn mower, snow blower, etc.,
be very careful and a lways obse rve loca l and
state laws regard ing the use, t ransportation
and sto rage of such fue l conta iners. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive yo ur vehicle unt il the fuel tan k is
comp letely empty . The irregular supply of
316
fu el can cause misfiring. Gasoline could ente r
the exhaust system and damage the catalytic
converter.

Selective catalytic reduction (AdBlue/DEF)
General information
Applies to: vehicles wit h 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 F lu 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
refi ll the Ad B lue yourse lf or have it refilled by an
authorized Aud i dea ler or authorized Audi Serv ice
Fac ility
c::;, page 319.
(0 Tips
- Th e d isp lay indicates the distance rema ining
that can be dr iven
c::;, page 318. If the Ad Bl­
ue tank is comple tely emp ty, the eng ine will
no t start again after the ign ition is switched
off .
-Ad Bl ue is required by law to ope rate th is ve­
hicle.
Messages in the instrument cluster display
App lies to: vehicles wi th selective catalyt ic reduct ion
The display indicat es if the Ad Blue level is low or
if there
is a system malfun ction.
AdBlue level low
You w ill be informed in the instrument cluster
display if the AdBlue in the tank drops below a
ce rtain level. Add at a minimum the amount of
AdBlue shown in the message:

:E: ' • Position the bottle on the filler tube and tu rn
the bottle clockwise unti l it stops turning.
• Press lightly against the bottom of the bottle
to empty it. Continue pressing the bottom of
the bottle until it is empty or until f luid stops
flowing into the tank .
• Remove the bottle and seal the filler neck
~ page 321, Completing AdBlue refill .
(D Note
Only use refill bottles that are approved for
your veh icle. Us ing other systems can cause
Ad Blue to leak.
- You can obta in refill bottles from an author­
i zed Audi dealer or author ized Audi Service
Fac ility.
- A perm itted refill bottle contains approxi­
mately 0.5 gallon ( 1.9 liters) of Ad B lue.
Completing AdBlue refill
Applies to: vehicles with selective catalytic reduction
Closing th e filler neck
• Turn the Ad Blue cap to the right on the filler
tube u ntil the cap clicks into p lace
c;> .&. in
Preparation on page 319,
c;> (D in Preparation
on page 319 ..
• Then press on the left side of the tank door un -
ti l it latches.
After filling
The vehicle must be driven so that the system
recognizes t hat the Ad Bl ue was refilled. This can
take severa l min utes .
• If there was no Ad Blue left in the tank and a
range of O mi (0 km) was shown in the display ,
switch the ign ition on for about 30 seconds be­
f ore star ting the engine .
(D Tips
Ad Blue in the tank can free ze at very low tem­
pe ra tures. If this happens, the system will
no t detect t hat the Ad Bl ue was refilled and i t
wi ll continue to inform you of the low Ad Blue
Ch eck ing and Filling
level. The message t urns off as soon as the
tank thaws out again .
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 ­
ces), the filter becomes clogged with soot and
the
1\1 i ndicato r light for the diese l part iculate
filte r tu rns on
c;> page 30.
_& WARNING
The tempera ture of the exhaus t sys tem is
high, bot h when driv ing and a fter stoppi ng
the engine.
- Never tou ch the e xhaust tail pipes once they
have become hot. This cou ld res ult in burns .
- Do not par k your veh icle over flamm ab le
materia ls such as grass or leaves because
the high temperature of the emissions con­ trol system (catalytic converter or diesel particu late filter) cou ld start a fire.
- Do not app ly underbody protectant in the
exhaust system area, beca use this increases
the risk of f ire.
