Starting and autom ati call y relea sing the
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 .

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.

When accelerating, the transmission will au­
tomatically shift into the next gear before the
engine reaches its maximum RPM .
If you apply a light throttle when accelerat­
ing, tiptronic will automatically shift from 1st
to 2nd gear to save fuel. If you apply a heavy
throttle, the transm iss ion will stay in 1st gear
until near maximum RPM is reached, or until
the driver shifts into 2nd gear .
If you take your foot off the accelerator pedal
when driving down a steep incline, tiptronic
will downshift from the selected gear into the
next lower gear until it reaches 1st gear,
based on road speed and engine RPM . Auto ·
matic downshifting is interrupted as soon as
you apply the throttle again .
(D Tips
-When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev­
ving the engine.
- When the kick-down comes on, the
transmission will shift down to a lower

98 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplaning). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rarily when driving in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- The adaptive cruise control system will
not brake by itself if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard will have limited function.
- The adaptive cruise control system and
braking guard do not react to people, an­
imals, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC
off when it is not being used.
{[) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive cruise control system and braking guard.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
, In curves
App lies to vehicles: wi th Audi ada ptive c ruise contro l
Fig. 97 Example: d riving i nto a curve
When driving into a curve ~ fig. 97 and out of
a curve, the adaptive cruise control may react
to a vehicle in the next lane and apply the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles : wi th Audi adapt ive crui se contro l
Fig. 98 Example: object changing lanes a nd stat ionary
object
The adaptive cruise control system only reacts
to objects that are moving or that the system
has already detected as moving. For example,
if a vehicle @, which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

(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

-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der 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.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system .
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
