Messages
Applies to : vehicles wi th Audi side ass ist
If side assist switches off by itself, the LED in the
button turns off and a message will appear in the
i nstrument cluster display:
Audi side assist: Currently unavailable. No
sensor vision
The radar sensor vision is impaired . Do not cover
the area in front of the sensors with bike wheels,
stickers, dirt or ot her objects . Clean the area in
front of the sensors, if
necessary ¢ page 106,
fig. 121 .
Audi side assist: Currently 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 guarantee that it will detect
vehicles correctly and it has switched off. The
sensors have been moved or are faulty . Have the
system checked by an authorized Audi dealer or
autho rized 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 switch off when using
a retrofitted trailer hitch. Do not use side ass ist
when towing a trailer.

Parking syste m s
-For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck. Do not
use the orientation lines in this case.
- If driven from a level surface onto an in­
cline, or a downward slope.
- If driven toward protruding objects.
- If the vehicle is carrying too much load in
the rear.
- The accuracy of the orientation lines and
blue surfaces decreases when the vehicle is
raised/lowered
¢ page 111.
(D Note
-Always read and follow the applicable warn ­
ings

front of the vehicle swings out more than
the rear of the veh icle. Maintain p lenty of
distance so that an exterior mirror or a cor­ ner of the veh icle does not co llide w ith any
obstacles.

Wheels
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
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
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
l uggage 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
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle'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
296
carried in the vehicle (including
the weight of a trailer 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 l uggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 293,
fig. 266.
_& WARNING ~
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.

J: ..
-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 Vehicle 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 vehic le 's placard
(tire inflation pressure label)
¢ page 293, fig. 266 .
Wheels
2. Determine the combined
weight of the driver and pas­sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 293, fig . 266 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals
1400 lbs. and there wil l
be five
150 lbs . passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 X 150) = 650
lbs .)
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. Consult this manual to
determine how this reduces

safety precautions :
Emergenc y ass is tanc e
-If you have a flat tire, move a safe distance
off the road. Turn off the eng ine, turn the
emergency flashers on and use other warn­ ing dev ices to alert other motorists .
- Make sure that passengers wait in a safe
p lace away from the vehicle and well away
from the road and traff ic .
- To help prevent the veh icle from moving
suddenly and possib ly slipping off the jack ,
always fu lly set the par king brake and block
the front and back of the wheel diagonally
opposite the wheel being changed. W hen
one front w heel is li fted off the gro und,
p lacing the Au tom atic Transmi ssion in P
(Park) will
not p revent the vehicle from
mov ing.
- Before you change a wheel, be sure the
g ro u nd is leve l and firm. If necessary, use a
sturdy board under the jack .
- Always s tore the vehicle tool ki t, the jack
an d the replaced tire in the luggage com­
pa rtment ¢

(D Tips
Befo re c hangin g the wheel, you mus t activ ate
the jacking mode, so that the a utomat ic con ­
tro ls for the Adaptive Air Suspension do not
make it more di fficult to lift the vehicle with
the jack

Changing a wheel
When you change a wheel , follow the sequence
described below step -by-step and in exactly that
order .
1. Activate the vehicle jack mode ¢ page 315 .
2. Remove the de corative wheel cover *. For
more detai ls see
