Starting and automatically releasing the
par king brake
.. When you sta rt 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 stopping
in city traffic, the parking brake can be ap
plied. The veh icle does not have to be held
with the footbrake. The parking 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 veh icle sta rts to move .
Starting on slopes
When starting on inclines, the starting assist
prevents the vehicle from unintentionally roll
ing back . The braking force of the parking
brake is not released until sufficient dr iving
fo rce has been bu ilt 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 buck le.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch
accelerator. The park ing brake stays applied
and prevents the vehicle from rolling back
ward.
.. You can release the switch
C®l once you are
sure that you a re developing enough for
ward momentum at the wheels as you de
press the accelerator .
Depending on the weight of the rig (vehicle
and trai ler) and the seve rity of the incline, you
may roll backwards as you start. You can pre
vent rolling backwards by holding the parking brake switch(®) pulled out and accelerating -
just as you would when starting on a hill with a conventional hand brake .
Emergency braking
In the event that the conventional brake sys
tem fails or locks .
.. In an emergency, pull the switch C®l and
con tinue to pull it to slow your vehicle down
w ith the park ing brake.
.. As soon as you release the switch (®) or ac-
celerate, the brak ing process stops.
If you pull the switch C®l and hold it above a
speed of about 5 mph (8 km/h), the emergen
cy brak ing funct ion is initiated . T he vehicle is
braked at all fou r whee ls by activating the hy
draulic brake system. The brake performance
is similar to making an emergency stop~&. .
In order not to act ivate the emergency brak
ing by mis take, an audib le warning tone (buz
zer) sounds whe n the switch(®) is pulled . As
soon as the sw itch C®l is released , or the accel
erator pedal is depressed, emergency braking
stops.
_& WARNING
-Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed.
Using the parking brake to perform emer
gency braking will slow your veh icle down
as if you had made a full brake application .
The laws of physics cannot be suspended
even with ESC and its associated compo
nents (ABS, ASR, EDL) . In corners and
when road or weather conditions are bad,
a full brake application can cause the vehi
cle to skid or the rear end to break away -
risking an accident.

vehicles or obstacles that are not moving
can trigger a collision warning and if con
firmed by the video camera, an acute col lis ion warn ing.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these cond itions cou ld result in a co lli

celerating to the set speed when in these
situations .
- The adapt ive cru ise control system w ill
not brake by itse lf 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 w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people , an

- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise cont ro l c anno t slow or
brake the veh icle safely when you follow
another vehicle too closely. Always re
member that the automatic braking
funct ion cannot bring the veh icle to a

Audi active Lane assist
Active Lane assist
Description
Applies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane.
Active lane assist detects lane marker lines
within the limits of the system using a camera in the windshield . If you are approaching a de
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
driver can over ride the cor re ct ive steer ing at
any time. If the veh icle crosses a line, the d riv
er is also warned by a light
vibration in the
steering whee l. The vibration warning must
be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc
cur since the system allows for intentional lane changes .
The system is designed for driv ing on free
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more .
If the vehicle is also equipped with Audi adap
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect
ed i n close proximity to the veh icle, Audi a c
tive lane ass ist helps prevent the vehi cle from
driving too close to them . The re is also pass
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the driver that the ve
hicle is leaving the lane us ing corrective
Audi acti ve lane a ssis t 95
steer ing. The driver is always responsible
for keeping the vehicle within the lane.
- The system can assist the driver in keep
ing the vehicle in the lane, but it does
not steer by itself. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer tain sit uat ions, such as dur ing heavy
brak ing.
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross
winds, the corrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather condit ions such as
slippery roads, fog, gravel, heavy rai n,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e con
ditions may increase the risk of a crash.
