If side assist sw itches off by itself, the LED in the
button turns off and a message will appear in the
i nstrument cluster display:
Audi side assist: Unavailable . Sensor vision
The radar sensor vision is impaired. Do not cover
the area in front of the sensors with bike whee ls,
stickers, dirt or other objects. Clean the area in
front of the sensors, if necessary

Audi side assist: Unavailable.
Side assist cannot be switched on at this time be­
cause there is a malfunction (for example, the
battery charge level may be too low).
Audi side assist: System fault!
The system cannot gua rantee that it will detect
vehicles correct ly and it has switched off. The
sensors have been moved or are fa ulty . Have the
system checked by an authorized Aud i dealer or
authorized Aud i Serv ice Facility soon .
Audi side assist: Unavailable when towing
Side assist switches off automatically when a fac­
tory- installed trailer hitch is connected to the
electrical connector on the trailer. There is no
guarantee the system will switc h off when using
a retrofitted trailer hitch. Do not use side assist

General information
A ppl ies to: ve hicles w ith a rea r parking sys te m /pa rking sys ­
tem p lus/rearv iew camera
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear park ing system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 83.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 83.
The rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or maneuver
¢ page 84.
_& WARNING
-Always look for traff ic 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.
-
- Always pay attention to the area around the
vehicle -using the rearview mirror, too.
- The sensors can be displaced by impacts or
damage to the radiator grille, 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
t io n.
- Make sure the sensors are not obstructed by
stickers, deposits or other materia ls. If they
are, the sensor function could be impaired.
82
For additional information on cleaning, see
¢page 185.
(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.
@ 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.
- The sensors must be kept clean and free of
snow and ice for the parking aid to operate .
For information on cleaning, see
¢page 185.
- You can change the volume and pitch of the
signals as well as the display¢
page 87.
-Please refer to the instructions for towing a
trailer located in
¢page 88.
- What appears in the infotainment display is
somewhat time-delayed.

fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
1 50 lbs. (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gr oss Axle Weight R ating
("GAWR") is the maximum load
that can be applied at each of the
veh icle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trai ler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
~ luggage.

The Gross Vehicle Weight Rating and the Gross Axle Weight Rating

ance sticker label located on the

_&. WA RNIN G
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
- Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
- Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
- Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle heavier than the vehicle's
Gross Veh icle Weight Rating .

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard
(tire inflation pre ssure label)
c:::> page 176, fig. 146.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
"XXX" kilograms or " XXX"
pounds shown on the sticker
c:::> page 176 , fig. 146 .
4. The re sulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals 1400 lbs. and there will
180
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and luggage load capacity calculat ­
ed in Step 4 .
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your ve­
hicle. Con sult this manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle .
~check the tire sidewall
(c:::> page 167, fig. 144) to deter­
mine the designated load rating
for a specific tire.
