pa rking b rake
~ When you start to drive as usua l, the park­
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopp ing
in city traffic on vehicles with an automatic
transmission, the parking brake can be ap­ plied. The vehicle does not have to be held
w ith the footbrake . The park ing brake elimi­
nates the tendency to creep with a drive range
engaged. As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle starts to move .
Starting on slop es
When starting on inclines, the start ing ass ist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not released until sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er 's safety belt is engaged in the bu ckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
~ Keep the switch@¢ page 77, fig. 77
pulled and depress the accelerator . The
park ing b rake stays app lied and p revents
the vehi cle from rolling backward.
~ You can release the switch @once you are
s u re that yo u are developing enough driving
force at the wheels by depressing the accel­ erator.
D epending on the weight of the rig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. Yo u can pre­
vent roll ing backwards by holding the parking
brake switch @pulled out and accelerating -
just as you would when starting on a hill wit h
a conventional hand brake .
On the ro ad 79
Emergency braking
In the event that the conventional brake sys­
tem fails or locks .
~ In an emergency, pull the sw itch @
¢
page 77, fig. 77 and continue to pull it to
slow your vehicle down with the parking
brake .
~ As soon as you release the switch @ or ac-
celerate, the b ra ki ng process s tops.
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the eme rgen­
cy bra king funct ion is initia ted . T he ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performa nce
is similar to making an emergency stop¢&..
In order not to act ivate the eme rgency brak­
ing by mis take, an audib le warning tone (buz ­
zer) so unds when the switch @is pulled. As
soon as the switch @ is re leased, or the acce l­
erato r peda l is depressed, emergency braking
stops.
A WARNING
...--
Emergency braking should only be used in
an emergency, when the normal foot brake has fa iled or the brake pedal is obstructed .
Using the par king b rake to pe rform eme r­
gency brak ing will slow your vehicle down
as if you had made a full bra ke application.
The laws of physics cannot be suspended
even with ESC and its associated compo ­
nents (ABS, ASR, EDS) . In corners and
when road or weather conditions are bad,
a full brake application can ca use the vehi­
cle to sk id or the rear end to break away -
risking an accident.

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
(D V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph ( 15
km/ h), t he display in the exterior mirro r turns
on as soon as the vehicle enters your blind
spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h).
Functional limitations
T he radar senso rs are designed to detect the
left and right adjacent lanes whe n the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on
even though there is no ve hicle locat­
ed in the area that is cr itical fo r a la ne cha nge.
Fo r example:
- if the lanes are narrow or if your are driving on t he edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to you r
cur rent lane .
- if you a re driving throug h a c urve . Side assist
may react to a vehicle that is one lane
ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist fu nctions are limited .
Do not
cover the radar sensors c::> fig. 110 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer . For

Driver messages
App lies to vehicles: with side assist
If side assist switches off by itself, the LED in
the button turns off and a message will ap­
pear in the instrument cluster display:
Audi side assist unavailable: Sensors blocked
The radar sensors' vision is affected. Do not
cover the area in front of the sensors with bike
wheels, stickers, dirt or other objects. Clean
the area in front of the sensors, if necessary
c:::;,page 108, fig. 110.
Audi side assist: Currently unavailable
Side assist cannot be switched on temporarily
because 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 de­
tect vehicles correctly and it is switched off .
The sensors have been displaced or are faulty .
Have the system checked by an authorized
Audi dealer or authorized Audi Service Facility
soon .
Audi side assist: Unavailable when towing
Side assist switches off automatically when a
factory-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 assist when towing a trailer.

_& WARNING
-Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub­
st itute for the driver 's own caution and
alertness. Ultimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone
else has driven the vehicle before you.
(D Note
-Remember that low obstacles for which
a warn ing has already been issued may
"dive" below the system's sensing zone if
the vehicle is being backed up closer. In
this case, the warning sound shutting off
does
not in dicate that you have cleared
the obstacle . Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect­
ed by the system. They can still damage
your vehicle without warning .
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous­
tic parking assist system can function
properly.
