On-Board Diagnostics
Fig. 19 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed 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
¢ page 269.
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 Link Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 19.
Your authorized Audi dealer or a qualified service
station can interpret the code and perform the
necessary repair.
A 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!
Electronic speed limiter
-
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
26
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
¢ page 290.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
ass istance.
58
Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your vehicle faster than the maximum speed rating
of the ti res installed.

Front passenger's exterior mirror tilt
function*
To help you see the curb when back ing into a
parking space, the surface of the mirror tilts
slightly. For this to happen, the knob must be in
the position for the front passenger's outside
mirror.
You can adjust the tilted mi rror surface by turn­
ing the knob in the desired direction. When you
move out of reverse and into another gear, the
new mirror position is stored and assigned to the
key you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off.
A WARNING
Curved mirror surfaces (aspheric or convex*)
enlarge the field of vision. However, they
make objects in the mirror appear smaller
and farther away. Your may estimate incor­
rectly when you use these mirrors to gauge
your distance from the vehicles behind you
when changing lanes, wh ich increases the risk
of an accident.
(D Note
- If the mirror housing was moved by outs ide
forces (such as an impact when maneuver­ in g), you must use the power fold ing func­
tion to fold the mirror all the way out. The
mirror housing must not be moved back in­
to place by hand because this would impair
the function of the m irror mechanism.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.

system may have detected a vehicle in another
lane that is not adjacent to your current lane.
- If you are driving through a curve. Side assist may react to a vehicle that is one lane over
from th e adjacent lane .
- If s ide assist reacts to other objects (such as
high or d isplaced guard ra ils).
- In poor weather condit ions. The side assist
functions are limited.

not use side ass ist when towing a trailer. For in­
formation on cleaning, see <=>
page 306.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
rep lace a driver's attention. The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers .
- In some situat ions, the system may not
func tion or its funct ion may be limited . For
example :
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in t ime .
- In poor weather conditions such as heavy
rain, snow or heavy mist .
- On very wide lanes, in tight curves, or i f
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
- Audi side ass ist cannot detect a ll vehicles
under a ll condit ions, which can increase the
risk of accidents.
- Please note that side assist only displays ap­ proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least
19 mph (30 km/h) .
- In certain situations, the system may not
work or its function may be limited. For ex ­
amp le:
- The display may not turn on at the rig ht
time if veh ides are approaching or passing
very q uick ly .

-
- In poor weather conditions, such as heavy
rain, snow or fog .
- In very wide lanes , in tight c urves or when
there are slopes in the roadway, vehicles
i n the ne ighboring lanes may not be de­
tected because they a re outside of the
sensor range .
(D Note
The sensors can be d isplaced by impacts or
damage to the bumper, wheel housing and underbody. This can impair the system. Have
an authorized Audi dealer or author ized Audi

0 co .... N ,..... N .... 0 0 :c ' depends on the driving mode selected, steering
movements, the driver's braking and accelera­
tion, and as the road surface, vehicle speed and load. A sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle ground clearance depends on the
mode selected and the speed. When you are in
the auto or dynamic mode, the highway setting is
activated when you drive above 75 mph (120 km/
h) for more than 30 seconds. The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times . This sets the steer­
ing to be less sensitive at higher speeds in order
to provide improved vehicle control. At reduced
speeds, steering is more direct in order to keep
the steering effort as minimal as possible when
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 130, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high level of agility and ability to accel ­
erate on curves. The vehicle is very responsive to
steering .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode .
Assist
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Note
- Make sure there is enough clearance above
and below the vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature fluctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspension struts or towing eyes is
not permitted because the pressure in the
air suspension struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatically
engages if the dynamic mode is selected.
- In vehicles that have dynamic steering*, op­
erating noise is heard when starting or stop­
ping the engine. This does not indicate a
problem.

are also available
¢page 115.
& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers .
- Please note that some surfaces , such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park­
ing system may be impaired as a result.
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion .
- Make sure the sensors are not obstructed by
stickers, deposits or other materials. If they
are, the sensor function could be impaired.

(D Note
-Some objects are not detected or displayed
by the system under certain circumstances:
- Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex ­
tensions
- Objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor range. Note that you will no longer be
warned about th is obstacle.
(D Tips
- The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass.
- external ultrasonic sources such as from cleaning vehicles .
- in heavy rain, snow, or thick vehicle ex­
haust.
- We recommend that you practice parking in
a traffic -free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume and pitch of the
signals as well as the display¢
page 124.
-Please refer to the instructions for towing a
trailer located in
¢page 124.
-What appears in the infotainment display is
somewhat time-delayed.
- The sensors must be kept clean and free of
snow and ice for park aid to operate .
