wheel AUDI A8 2011 Owner's Manual

Depending on the weight of the r ig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start. You 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 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(®) and
continue to pull it to slow your vehicle down
with the parking brake.
... As soon as you release t he sw itch (®) or ac-
ce lerate, the braking p rocess stops.
If you pull the sw itch(®) and hold it above a
speed of about 5 mph (8 km/h), t he emergen­
cy braking fu nction is in itiated . The vehicle is
b raked at all four wheels by activating the hy­
d ra u lic bra ke system. The b rake performance
i s simi lar to making an emergency stop
c::> &. .
In order not to activate the emergency brak­
ing by m ista ke, an audible warning tone (b uz­
z er) sou nds when the switch®> is pulled. As
soon as the switch(®) is released, or the acce l­
erator pedal is dep ressed, emergency brak ing
stops .
A WARNING
Emergency braking should only be used i n
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 you r vehicle down
as if you had made a fu ll brake applicat ion.
T he laws of physics can not be s uspended
even w ith ESP 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 -
r isking an accident.

Speed warning system
Introduction
The speed warning system helps you to stay
under 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
you r speed exceeds the stored value by ap­
proximately 3 mph (3 km/h) . An indicator
li ght . (USA
models) ;a (Canada mode ls) in
the instr ument cluster d isp lay al so tur ns on at
the same time. The indicator light . /.
turns off when the speed decreases be low the
stored maxim um speed .
Se tting a t hreshold is recommended if you
would like to be rem inded w hen you reach a
certain maximum speed. Situations where you
may want to do so incl ude driv ing in a co untry
with a genera l speed limit or if there is a
specified maximum speed for winter tires.
(D Tips
Even though your vehicle is eq uipped w ith
a speed warn ing system, you sho uld still
watch the speedometer to make sure you
are not dr iv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
... Select: !CAR ! function button > Car systems
contro l button > Dri ver ass ist > Speed warn­
ing .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Sett ings
can each be adjusted in increments of 5 mph
(10 km/h).

Adaptive cruis e control and bra kin g guard
vehicles such as motorcycles and bicy­
cles.
- The adaptive cruise control system can­
not detect people, animals and cannot
detect objects or traffic that crosses your
lane of travel.
- Never drive at speeds that are too fast for traffic, road and weather conditions.
- Never use adaptive cruise control when
you cannot drive safely at a steady speed, including on wind ing roads or
when road conditions are poor (for exam ­
ple, in construction sites, on ice , gravel,
in fog, heavy ra in or on wet roads that in­
crease the risk of hydroplan ing).
- Never follow a veh icle so closely that you
cannot stop your vehicle safely. The
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
another veh icle too closely. Always re ­
member that the automatic braking
function cannot bring the vehicle to a
sudden or emergency stop under these
condit ions.
- Never rest your foot on the acce lerator
pedal, especially when the adaptive
cruise control is being used. Pressure on
the accelerator w ill override the adaptive
cruise control braking function and pre­
vent the brakes from being applied whe n
adaptive cruise cont ro l detects a situa­
t io n when the brakes must be applied.
- Never use adaptive cruise control whe n
the radar sensors cannot accurately de­
t ect vehicles moving in t raff ic. The rad ar
sensor's vision can be reduced by heavy
rain, ice, snow, heavy road spray and re­
flect ions from guard rails, t unnel ent ran­
ces, etc. These and simi lar conditions can
prevent vehicles from being accurately
detected and in some cases they may not
be detected at all .
- Always turn off adaptive cru ise contro l
when entering turn lanes, exit lanes and
constr uction zones or in similar sit ua­
t ions because the vehicle will automati­
ca lly accelerate to the sto red speed when
the roa d ahead is clear. -
To prevent unintended operation, a lways
sw itch ACC off when it is not being used .
(D Note
The sensors can be moved by impac ts or
damage to the bumper, wheel housing and underbody . Damage in these areas could
change the way the adaptive cru ise control
system and Aud i brak ing guard work to­
gether . Have your authorized Audi deale r
check to make s ure that the adaptive
cruise control system is wor king p roperly if
your vehicle had a m ino r frontal impact or
was damaged in the area of the sensors.

Audi lane assist Lane assist
De scription
App lies to vehicles: with la ne ass ist
Lane assist helps you keep your vehicle in your
lane.
Lane assist uses a camera to detect lane boun ­
dary lines . If the system detects that your ve­
hicle is about to cross a detected lane boun­
dary line, the steering wheel
vibrates to alert
the driver . Lane assist is operable when the
line marking the lane is detected on at least
one side of the veh icle. This is ind icated by a
g reen indicator light. in the instrument
cluster.
If the system is in active standby mode and
the turn signal is activated before driving over
the bounda ry line, the warn ing does not occur
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.
A WARNING
- Lane assist will not keep your vehicle in
your lane . The system only warns the
driver when the vehicle is leaving the
lane . The driver is always responsible for
keeping the vehicle in the lane .
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines . This can lead to incorrect
warnings or wa rnings tha t fail to go off
at all.
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray o r light sh in ing
into the camera lens. Th is can cause lane
assist to fa il to detect boundary lines.

the instrument cluster indicator goes out and
one of the following messages appears on the
display:
Audi lane assist not available: Currently no
sensor vision
This message appears when the camera can
no longer function because it cannot detect
the boundary lines. This may be due to the
following:
- T he exterior side of the camera viewing win­
dow

Clean this part of the windshield.
- The camera viewing window is fogged up on
the inside. In this case, wait until the fog
disappears before turning lane assist on
again.
- The system was unab le to detect boundary
lines over an extended period of time due to
road conditions (such as snow-covered
lanes). Do not turn lane assist on again until
the lines can be more easily detected.

App lies to vehicles: with lane ass ist
You can adjust individual settings in the MMI.
~ Select : ICARI function button> Car systems
control button > Driver assist > Audi lane
assist.
Setting the warning point Early:
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the vehicle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you drive toward a boundary line at a very sharp angle, the warning will come just before
a wheel touches the line.
Medium: With this setting, the warning point
is adapted to the course of the road, the lane
width and the speed. You will still be warned

if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel vibration can be set to
Low, Medium or Strong. Selecting each of the
settings will cause the steering wheel to vi­
brate so you can check the strength of the vi­
bration in that setting.

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver 's ability to concentrate on the road
without being distracted.
The driver is respons ible for the safety of the
vehi cle and all of its occupants.
If you r ability
to drive is impa ired, safety r isks for everybody
i n the vehicle increase and yo u also become a
hazard to everyone else on the road
i;::;, .&_ .
Therefore:
• Do no t let yourself be distracted by passe n­
gers or by using a cellular telephone.
• NEV ER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
• Observe all traffic laws, rules of the road
and speed limits and plain common sense .
• ALWAYS adjust your speed to road, traff ic
and weather condit ions .
• Take frequent breaks on long trips . Do not
dr ive for more than two hours at a stretch.
• Do NO T drive when you are t ired, under
pressure or when you are stressed.
_8. WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Proper occupant

Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 1 36 Correct seat ing pos it ion
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
follow ing pos ition:
• Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
while keeping your knee(s) slightly bent
¢ A.
• Ad just the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact with it when you drive.
• Adj ust the steering wheel so that there is a
d istance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast
bone
i;::;, fig. 136. If not possible, see your au­
thorized Audi dealership about adaptive equipment.
• Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face .
• Grasp the top of the steer ing whee l with
your elbow(s) slightly bent.
• Adjust the head rest raint so the upper edge
is as even as possible with the top of your
head.
If that is not possible, try to adjust
the head restraint so that it is as close to
this position as possib le.
• Fasten and wear safety belts correctly
