Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faster a vehicle approaches,
the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles you are passing
If
you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than
9 mph (lS
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The
display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti­
cal for a lane change. For example:
-If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case , the
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 the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors
c!:> fig. 84 with
stickers, deposits, bicycle wheels or other ob-
Assist
jects, because they will impair the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning, see
c!:>page 191.
A WARNING
-- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers .
- Improper reliance on the side assist system can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(I) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or authorized Audi
Service Facility check their function.

Parking systems
-If the position and the installation angle of
the rearview camera was changed, for ex­
ample after a collision, do not continue to
use the system for safety reasons . Have it
checked by an authorized Audi dealer or au­
thorized Audi Service Facility.
- Only use the rearview camera to assist you if
it shows a good, clear picture. For example,
the image may be affected by the sun shin­
ing into the lens, dirt on the lens, or if there
is a malfunction.
- Use the rearview camera only if the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggag e compartment lid do not block
the rearview camera.
- The camera lens enlarges and distorts the
field of vision. The object appears both al­
tered and inaccurate on the screen.
- In certain situations, people or objects in the display appear closer or farther away:
- 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 .

Wheels
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 1 SO 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
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
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 luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
184
driver's side B-pillar ¢ page 181,
fig. 149.
~ 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.
-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 ma ke 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 pla card
(tire inflation pre ssure l abel)
¢ page 181, fig. 149.
2 . Determine the combined
weight of the drive r and pas­
s engers 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
¢ page 181 , fig. 149 .
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
Wheels
be five 1 SO lbs. pa ssengers in
your vehicle, the amount of available cargo and luggage load capacity i s 650 lb s.
(1400-750 (5 X 150) = 650
lbs.)
5. Determin e 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 capa city cal culat­
ed in Step 4 .
6. If your vehi cle will be towing a
trailer, load from your trailer
will be transferred to your ve­
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle.
..,.Check the tire sidewall
(¢page 171 , fig. 147) to deter­
mine the designated load rating
for a specific tire.
