The assist systems analyze the data from various
sensors and cameras installed in the vehicle. Do
not use any assist systems if there is damage in
there area of the sensors and cameras or on the
vehicle underbody. Damage can impair the func-
tion of the sensors and cameras or cause mal-
functions. Have an authorized Audi dealer or au-
thorized Audi Service Facility check their func-
tion.
Radar sensors
Depending on the vehicle equipment, the area
surrounding the entire vehicle may be detected
> fig. 106 ©.
The wheel sensors on the rear corners of the vehi-
cle are positioned so that the adjacent lanes to
the left and right are detected on roads with a
normal lane width.
Ultrasonic sensors
Depending on vehicle equipment, various areas
may be displayed in the MMI using the ultrasonic
sensors > fig. 106.
The range of the displays depends on the location
of the ultrasonic sensors:
@ Approximately 4 feet (1.20 m)
@® Approximately 3 feet (0.90 m)
@® Approximately 5.2 feet (1.60 m)
© Approximately 3 feet (0.90 m)
© Approximately 3 feet (0.90 m)
The side area © is detected and evaluated when
passing. There may have been changes to the sur-
rounding area after switching the ignition off and
on again, after opening the doors, or if the vehi-
cle is left stationary for a period of time. In this
case, the area will appear black until the area has
been detected and evaluated.
Cameras
Use the camera image on the display to assist you
only if it shows a good, clear picture. Keep in
mind that the image in the display is enlarged
and distorted. Under certain circumstances, ob-
jects may appear different and unclear on the dis-
play.
The rearview camera can only detect the area
marked in red > fig. 107. Only this area is dis-
played on the center display. > A\.

ZA WARNING
Sensors and cameras have spots in which the
surrounding area cannot be detected. Objects,
animals, and people may only be detected
with limitations may not be detected at all.
Always monitor the traffic and the vehicle's >

Fig. 127 Driving situations and exterior mirror display
General information
Side assist monitors the blind spot and traffic be-
hind your vehicle and provides assistance when
you are changing lanes. If the system detects an
object approaching and classifies it as critical, the
display @ in the exterior mirror on that side of
the vehicle will turn on,
Driving situations
The side assist warning is active at speeds above
approximately 9 mph (15 km/h) and can help in
situations such as the following:
@ Your vehicle is being passed. The faster an-
other vehicle approaches from behind, the
sooner the display in the outside mirror will
turn on.
@® There are vehicles traveling in the same direc-
tion as you in a lane adjacent to yours. The
display in the exterior mirror will turn on
when the detected object is in the “blind
spot”, at the latest.
@ You are slowly passing another vehicle. If the
difference in speed between the two vehicles
156
is less than 9 mph (15 km/h), the display in
the exterior mirror will turn on.
Information stage
If you do not activate a turn signal, the system
will inform you about objects classified as critical
by turning on the display in the respective exteri-
or mirror. The display remains dim in the infor-
mation stage so that you are not distracted while
looking forward.
Warning stage
Once you activate a turn signal, the system will
inform you about objects classified as critical by
turning on the display in the respective exterior
mirror.
Depending on vehicle equipment, the display
may also provide a warning when the turn signal
is not activated: if driver assist systems detect
that your vehicle is about to leave a lane, the dis-
play will blink to warn you about objects classi-
fied as critical. You can also be warned with cor-
rective steering > page 150, Audi active lane as-
sist/lane departure warning.
System limitations
The system uses the data from the radar sensors
at the rear corners of the vehicle > page 128,
fig. 109. They are designed to detect the left and
right adjacent lanes when the road lanes are the
normal width. In some situations, the system
may react to vehicles in your own lane or lanes
that are not directly adjacent to yours, or to ob-
jects on the side of the road. In this case, the dis-
play will turn on even though there is no vehicle
in the critical area. These situations may include:
— Driving on the edge of your own lane
— Narrow lanes
— Curves
— High barriers on the side of the road

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126. >

low speed. For the best parking results, the ve-
hicle should be approximately 3 feet (1 m) from
the row of parking spaces.
> The parking space search is first done on the
side of your lane. To switch the side for the
parking space search, activate the turn signal
for that side. Depending on vehicle equipment,
you may also be able to press on the side next
to your vehicle in the center display.
Selecting the parking space
If the system finds a parking space that could be
suitable for the vehicle length and width, it will
be displayed. The system automatically suggests
a parking option @.
If the parking space allows different parking op-
tions, they can be selected manually. Press one of
the suggested parking options (@ in the center
display.
Starting the parking process
As soon as the vehicle has reached the correct po-
sition, a P will appear in the center display above
the selected parking space @). The roof in the
parking aid display @) may show the required
braking or driving direction.
> Keep the vehicle as parallel as possible to the
parked vehicles or to the side of the road.

Maneuvering area
The vehicle can go off course during the parking
process > A\. If there are obstacles within the
maneuvering area that block or endanger the
parking process, for example on the opposite
side of the street, a message may appear. You
may need to drive farther forward and stay closer
to the row of parking spaces.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 126.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Note
— Parking spaces classified as suitable by the
system may have been detected incorrectly.

Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

Z\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of
vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 280, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.

Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 244. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 254.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
260
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
Gi) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 4&4 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
() Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
