Driver information display
Fuel supply too low I
When the symbol illuminates, this means there are about 2.6
gallons (10 liters) of fuel left in the fuel tank. Time to refuel!
=;, page 221.
If the symbol lights up, even when there is ample fue l in the tank, and
the text
Tank system malfunction! Please contact workshop appears
in the display, there is a fault in the system. Contact a qualified work­
shop to have the fault rectified .•
App lies to veh icles: w ith eng ine speed limitat ion
Engine speed limitation ~
Engine speed maximum XXXX RPM
The symbol illuminates when there is an engine control malfunc­
tion. The indicator light
C in the instrument cluster also illuminates.
Th e eng ine speed is limited to the speed displayed in the driver infor­
mation system. Keep in mind that the engine speed will not exceed
the value disp layed in the driver information system, for example
when downshifting .
Please go to an authorized Audi dealer or other qualified workshop to
have the malfunction repai red. •
App lies to vehicles: with diesel eng ine and diesel particulate filter
Diesel particulate filter clogged
Particulate filter ! See owner's manual
If the indicato r light in the instrum ent cluster comes on, the
diesel particulate filter has become blocked with soot as the result of
constant short -distance driving. When the symbol illuminates,
you can alter your driving style to assist the filter self-cleaning
process. Drive for approximately 15 minutes in 4th or 5th gear (auto­
matic transm ission w ith the selector lever in the 5 posit ion) at a min
imum speed of 37 mph (60 km/h) and an engine speed of approx­
imate ly 2,000 RPM. The temperature increase that will result from
this can burn off the soot in the f ilter. The symbol will switch off when
the cleaning is successful. After a successfu l cleaning, there is no
need to bring the car to an authorized dealer or qualified workshop
because this is part of normal vehicle operation.
If the symbol does not switch off, see your authorized dealer or
other qualified workshop to have the problem corrected.
As long as the indicator light remains on (diese l particulate filter
plugged), you can expect increased fuel consumption and poss ibly
also a loss of engine performance.
For more information on the diesel particulate filter, refer to
=;, page 199.
& 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. •
