2011 AUDI S8 lane assist

104 Audi side assist
right of your travel lane, depending on wheth­
er you drive in the center of your lane or closer
to the edge.
If you drive in narrow lanes, s ide ass ist's de­
tection a rea may a lso include other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 108. Under these cond it ions ,
vehicles can also be detected that are two lanes away, and side assist then could switch
between the informat ional and warn ing stage
signals .
When driving in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area.

blocked
The side assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢ page 98, fig. 99 . To ensure that
you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
ve rsely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no vehicl e is detected for a longer period of
time while driving, side assist will also switc h
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
ve hicl e's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
The radar senso r's view is limited when tow ­
ing a trai le r. F or vehicles with a factory instal­
l ed towing hitch or a trailer hitch that was in­
sta lled later according to factory specifica­
tions, side assist is automatically deactivated as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed acco rding to facto ry
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driv ing aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driv ing to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is sa fe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident! ..,.

-Side assist cannot detect vehicles in time
to alert you when they approach from
behind at very high speed, or fall drop
back very quickly .
- The radar sensor 's
vision can be reduced
or entirely blocked by rain, snow, and
heavy spray . This can result in side assist
not adequately detecting vehicles or, in
some cases, not detecting them at all.
Always keep an eye on the direction you are traveling and the relevant area
around the vehicle.
- Please note that side assist indicates
there are approaching vehicles, or vehi­
cles in your blind spot, only after your ve­
hicle has reached a driving speed of at
least 19 mph (30 km/h).
- Side assist signal does not work around
tight corners (turning radius less than
328 feet, or 100 m).
- Side assist is no replacement for the driv­
er's full attention. The driver alone is re­
sponsible for lane changes and similar driving maneuvers. Always keep an eye
on the direction you are traveling and the
relevant area around the vehicle.
(D Note
To ensure that side assist is not adversely
affected, you should not block the area on
the rear bumper where the radar sensors
are located with foreign objects (such as
with stickers or bicycle racks).
If the positions of the radar sensors have
been changed as a result of a rear end-col­
lision, for instance, have side assist
checked by an authorized Audi dealer for
safety reasons.

190 Intelligent technology
Intelligent technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs for the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a control unit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the engine is running. ESP detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw) out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steer ing assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
liJ in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP cannot overcome the laws of
physics. It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered w ith water,
slush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a ve hicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle unde r con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

208 Cleaning and protection
-Never wash your car in bright sunlight.
Drops of water act as magnifying lenses
and may damage your paint.
- When you wash your car in the winter: if
you rinse your vehicle with a hose, be
careful not to aim the stream of water
directly at locks, or at door or hatch
openings - they can freeze shut.
- Never use sponges des igned to remove
i nsects, or any kitchen scouring sponges
or similar products . They can damage
your paint finish .
- Never use a dry cloth or sponge to clean
the headlights. Only use wet cloths or
sponges to prevent scratches .
It is best
to use soapy water.
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, fo r example when refuel­
ing your vehicle. Never clean the head­
lig hts w ith a dry cloth or sponge. Use a
wet cloth or sponge . It is best to use
soapy water.
@ For the sake of the environment
I n the interest of the environment, the ve­
hicle should only be washed in special
wash bays.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you observe a few simple rules.
• Before using the power washer, make sure
you have read and understood the WARN­
INGS
c:> A in General information on
page 206 .
• Always follow the operating instructions for
the power washer .
• Make sure that the jet on the spray hose pro­
duces a "fan shaped spray".
• Do
not hold the spray nozzle too close to
soft materia ls.
When cleaning the vehicle wit h a power wash­
er
always follow the operating instructions. T
his applies particu larly to the
operating
pressure
and the spraying distance. Keep a
distance from soft materials such as rubber
hoses or insulating material as well as sensors
and camera lenses.
Do not use a jet which sprays water in a
di rect
stream
or one that has a rotating jet .
Water temperature should not exceed 140 °F
(60 °().
A WARNING
Never wash tires with a jet that sprays wa­
ter in a direct stream . This could cause in­
v is ible damage to the t ires and weaken
them, even if the spray is from
a relatively
long distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal injury .
(D Note
To avoid damaging your vehicle, always
make sure that there is suffic ient d istance
between the spray head and soft materials
like rubber hoses, plast ic parts and sound­
deadening materials as well as sensors
and camera lenses. Never aim the sp ray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers. Remember: the
closer the nozzle is to the surface of the
mater ia l, the greater the stress on the ma­
terial.
Sensors and camera lenses
- Remove snow with a hand brush and remove
ice with a de-icing spray that does not con­
tain solvents .
- Clean the sensors (adaptive cruise control*,
pa rking system*) w ith a cleaning so lution
that does not contain so lvents and a soft
cloth.
- The camera lens or the area in front of the
camera lens is normally cleaned by the
w indshie ld w ipers (Audi lane assist*) or
headlight wipers (night vision system*) . If
the lens or the area is exceptionally dirty,
