back. The braking force of the parking brake is
only released if sufficient drive power has been built up at the wheels.
(D Tips
For safety reasons, the parking brake is only
released automatically when the driver's safe
ty belt is buckled.
Emergency braking function
This is used if the conventional brake system
fails or locks up.
... To brake your vehicle in an emergency , pull the
~ switch and hold it pulled .
... As soon as you release the~ switch or acceler-
ate, the braking stops.
If you pull the switch(®) and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking function is initiated. The vehicle is braked
at all four wheels by activating the hydraulic brake system. The brake performance is similar
to making an emergency stop¢.&..
In order not to activate the emergency braking by
mistake, an audible warning tone (buzzer)
sounds when the~ switch is pulled. As soon as
the ~ switch is released, or the accelerator pedal
is depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal brake pedal has
failed or the brake pedal is obstructed. Using
the parking brake for emergency braking will
slow your vehicle down as if you had made a
full braking maneuver. ESC and the associat
ed components (ABS, ASR, EDL) cannot over
come the laws of physics. In corners and
when road or weather conditions are bad, a
full brake application can cause the vehicle to
skid or the rear end to break away, which in
creases the risk of an accident.

Speed warning system
' Introduction
The speed warning system helps you to stay un
der a specified maximum speed .
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
You will hear a warning tone when your speed ex ceeds the stored value by approximately 3 mph
(3 km/h) . An indicator light. (USA models)/.
(Canada models) in the instrument cluster dis
play also turns on at the same time. The indicator
light./. turns off when the speed decreases
below the stored maximum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Even though your vehicle is equipped with a
speed warning system, you should still watch
the speedometer to make sure you are not
driving faster than the speed limit.
' Setting the threshold
You can set, change and delete the warning
threshold in the Infotainment system.
... Select: the I CARI function button > (Car)* Sys
tems
control button > Driver assistance >
Speed warning .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 5 mph (10
km/h).

Audi active lane assist
Lane assist
Description
A pp lies to: ve hicles w ith Audi active lane assist
Active lane ass ist detects lane marker lines with
in the limits of the system us ing a camera in the
windshie ld. If you are approaching a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you with
corrective steering. You can override this steering
at any time. If you pass over a line, the steering
wheel will vibrate lightly. In order for this warn ing vibration to occur, it must first be switched
on in the Infotainment system. Act ive lane assist
is operable when the lane marker line is detected
on at least one side of the vehicle.
The system is designed for driving on freeways
and expanded highways and thus works only at
speeds of 40 mph (65 km/h) or more.
Applies to vehicles w ith side assist*: if you act i
vate a turn s ignal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach ing you, there w ill be not iceable correct ive steer
i n g short ly before you leave the lane. This will at
tempt to keep your vehicle in the lane.
Appl ies to veh icles w ithout s ide ass ist* : the sys
tem does not warn when it is ready if you activate
the t urn signa l before crossing the lane marker
line. In this case, it ass umes that you a re chang
ing lanes intentionally.
Applies to vehicles w ith adapt ive cr uise control*
or pa rk ing aid*: the co rrective steering is ta rget
ed based on the d riving situation. In addition to
the lane marker lines, the system can also take
into account other objects such as guard rails. If
they are detected in close proximity to the vehi
cle, active lane assist helps prevent the vehicle
from dr iv ing too close to them. There is a lso
passing assistance . The system does not provide
any corrective steer ing if it detects that you are
passing anothe r vehicle.
88
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in the lane, but it does not drive by itse lf. Al
ways keep your hands on the steering
wheel.
- Cor rective steering may not occur in certain
situations, such as du ring heavy braking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Correc
tive stee ring can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Othe r road stru ctures or objects could poss i
bly be identified un intent ionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occ ur.
- The camera view can be restricted, for ex
ample by vehicles driving ahead or by rain,
snow, heavy spray or lig ht shining into t he
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de
tect ing them incorrectly.
- Under certain cond it ions such as r uts in the
road, a banked roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the m iddle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy rain, snow and the po tential fo r hydrop laning. Using active lane
assist under these cond it ions may increase
the risk of a crash .

or because they are obstructed by snow, dirt,
water or backlighting).
- The vehicle's speed is below the speed needed
to activate it, which is about 40 mph (65 km/

(D Vehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some
what far away. The faster a veh icle approaches ,
the sooner the display in the exterior mirror w il l
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
92
are indicated by the time they enter your "blind
spot", at the latest .
@ Vehicles left behind
If you slow ly pass a vehicle that side assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or 15
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 ass ist has detected (the differ
ence in speed between the vehicle and your vehi
cle is greater than 9 mph or 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 certa in situations, the dis
play in the exterior mirror may turn on even
thou gh there is no vehicle located in the area
that is crit ica l for a lane change. For example:
- if the lanes a re narrow or if your are driving on
the edge of your lane . If this is the case, the
system may have detected the vehicle in anoth
er lane that is
not adjacent to your current lane.
- if yo u 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 rai ls).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors <=?
fig. 104 with
stickers, deposits, bicycle wheels or other ob
jects, because this wi ll affect the function. For in
format ion on cleaning, refer to <=?
page 193.
_& 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 a nd
similar driving maneuvers .
- Improper reliance on the side ass ist system
can cause collis ions and serious pe rsonal 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 w ide 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 authorized
Audi Serv ice Facility check their function .
