Indicator lights overview
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal-
functions. Some warning and indicator lights
turn on when you switch the ignition on and must
turn off when the drive system is switched on or
while driving.
With some indicator lights, messages may ap-
pear and warning signals may sound. The indica-
tor lights and messages may be covered by other
displays. To show them again, select the second
tab for messages with the multifunction steering
wheel & page 13.
Some indicator lights in the display can display in

Image recording
Surrounding area monitoring
Applies to: vehicles with surrounding area monitoring
The functionality of the park assist plus requires
detecting and evaluating the vehicle's path. This
is done by cameras installed permanently on the
vehicle that detect objects in the vehicle's sur-
roundings (such as obstacles or guard rails). The
live images from the cameras are transmitted to
the applicable control module.
The camera images are transferred to the respon-
sible control module for processing and may be
stored, depending on vehicle equipment. The
control
module analyzes the current camera im-
age using image evaluation software. This image
evaluation software detects anonymized techni-
cal measurements, such as distances to objects.
The control module evaluates these technical
measurements and makes it possible for the as-
sist systems to control the vehicle, if necessary.

Fig. 212 Driver's side footwell: connection port for the On
Board Diagnostic System (OBD)
Your vehicle is equipped with electronic control
modules for various vehicle systems such as the
airbags. These vehicle control modules store data
while driving normally that is required by an au-
thorized Audi dealer or authorized Audi Service
Facility for diagnosis and repair purposes. Only
certain types of data are recorded for a very short
period of time if a control module has detected a
system event. No noises, conversations, or im-
ages will be recorded in the vehicle.
The data may include information such as the ve-
hicle speed, the direction of travel, and informa-
tion about the brake system, or also the behavior
of the restraint system in the event of an acci-
dent. The stored data can be exported and down-
loaded with special devices, which must be con-
nected directly to the vehicle.
On Board Diagnostic System (OBD)
There is a diagnostic connector socket in the driv-
er's side footwell to read out the various control
modules and the event data recorder. Data re-
garding the function and condition of the elec-
tronic control modules is stored in the event
memory. Only have an authorized Audi dealer or
authorized Audi Service Facility read out and de-
lete the event memory.

ZA\ WARNING
— Incorrect use of the connection port for the
On Board Diagnostic System can cause mal-
functions, which can then result in accidents
and serious injuries.
— Only allow an authorized Audi dealer or au-
thorized Audi Service Facility to read out the
engine data.
h data recorder
Event Data Recorder

This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions,
such as an airbag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle's system performed. The EDR is
designed to record data related to vehicle dynam-
ics and safety systems for a short period of time, >
