95 RON AUDI A8 2018 Repair Manual

Ass is tanc e system s
In the sporty dynamic mode, the transmission
shifts at higher speed ranges.
Air su spen sion
The adaptive air suspension/adaptive air suspen­
sion spo rt* is an e lectron ica lly contro lled a ir sus ­
pens ion and damping system . The adjustment
depends on the driving mode selected, steering movements, the driver's braking and accelera­
tion , and as the road surface, vehicle speed and
load . A sporty sett ing is generally used in vehicles
with adap tive a ir suspension sport*.
The vehicle ground clearance depends on the mode se lected and the speed . When you are in
the auto or dynamic mode, the h ighway sett ing is
activated when you dr ive above 75 mph (120 km/
h) for more than 30 seconds . The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Stee ring
The power steer ing adap ts . Indirect steer ing that
moves easily as in comfort mode is especially
suited to long drives on a h ighway . The dynam ic
mode p rovides spo rty , d irect steering.
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to ma intain optimum steering ef­
fort for the dr ive r at all times . This sets the steer­
i n g to be less sensit ive at hig he r speeds in o rder
to p rovide imp roved vehicle contro l. At reduced
speeds, steer ing is more direct in order to keep
the steering effort as minima l as possib le when
the driv er is maneuvering the v ehicl e. At low and
average speeds, dynamic steering* addit ionally
provides more responsive steering performance.
Sport diff ere ntial *
As a component of the all wheel drive system (quattro)
¢ page 131, the sport differential dis ­
tributes the driving power to the rear axle de ­
pending on the situation. The distribution of
power va ries from balanced (comfort) to sporty
(dynamic) depending on the selec ted mode . The
goal is a high level of agility and ab il ity to accel ­
erate on curves . The ve hicle is very respons ive to
steer ing .
112 Corn
ering light *
The co rnering ligh t adapts the hig h beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode.
Adaptive cruise cont rol*
The be hav io r whe n accelerat ing ca n be adjusted
from comfortable to sporty, depending on the drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more cons ervative or sporty manner.
Engine sound *
The eng ine sound adapts to the c urrent mode
and can be subtle to spo rty.
{[» Note
- Make s ure there is enough clearance above
and be low the vehicle when pa rk ing . T he
heig ht of t he ve hicle can change on ce it is
parked d ue to temperature fluctuations,
changes to the load conditions and changes
to the driv ing modes, which can affect clear­
ance .
- When transporting the vehicle on a car car ­
rier, train, ship or by other means, on ly tie
the vehicle down at the runn ing surface of
the tires, which is the outer c ircumference.

& WARNING
-Always look for traffic and check the area
around your vehicle by looking at it direct ly
as well. The parking system cannot replace
the driver's attent ion. The driver is always
responsible when enter ing or leav ing a park­
ing space and during similar maneuvers.
- Please note that some surfaces, such as
clothing, are not detected by the system .
-
-Sensors and cameras have blind spots in
wh ich people and objects cannot be detect­
ed . Be especially caut ious of small children
and animals .
- The sensors can be displaced by impacts or
damage to the radiator gr ille, bumper,
wheel housing and the underbody . The park­
ing system may be impa ired as a result.
Have a n author ized A udi dealer or author­
ized Audi Serv ice Facility check their func ­
tion .
- Make s ure the senso rs a re not obstructed by
stickers, deposits o r other materia ls. If they
are, the sensor function could be impaired.
For additiona l information on cleaning, see
¢ page 306.

@ Note
-Some objects are not detected or disp layed
by the system under certain circumstances:
- objects such as barrier cha ins, tra iler draw
bars, vertical po les or fences
- objects above the sensors such as wall ex ­
tensions
- objects with certain surfaces or structures
such as cha in link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor range . Note that you will no longer be
wa rned about t his obstacle.
(D Tips
-The system may provide a warning even
tho ugh the re are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- externa l ultrasonic sources such as from
cleaning vehicles
- in heavy rain, snow, or th ick vehicle ex ­
haust
- We recommend tha t you practice par king in
a traffic-free location or parking lot to be ­
come fami liar with the system . W hen doing
this, there sho uld be good light and weath­
er conditions.
- You can change the volume and pitch of the

Parking system plus provides audio and v isual
signals when parking .
C>
Fig. 129 Displa y fi eld
Sensors are located in the front and rear bump­
ers. If these detect an obstacle , audible and visu­
al signals warn you.
Make sure the sensors are not covered by stick­
ers, depos its or any other obstructions as it may
impair the sensor function. For information on
cleaning, see

The display field begins approximately at:
® 4 ft (1.20 m)
® 3 ft (0.90 m)
© 5.2 ft (1.60 m)
@ 3 ft (0.90 m)
The closer you get to the obstacle, the shorter
the interval between the audible signals. A con­
tinuous tone sounds when the obstacle is less
than approximately 1 foot (0.30 meters) away.
Do not continue driving forward or in reverse

Parking systems
Peripheral cameras
Introduction
Applies to: ve hicles with per ipheral cameras
W ith this equipment, the parking system plus*
¢ page 116 is supplemented w ith vario us periph­
eral cameras.
The four cameras g ive you the following views:
area around the vehicle, front corner view and rear corner v iew, view in front of the veh icle and
behind the vehicle.
General information
Applies to: ve hicles w ith pe ripheral cameras
F ig. 139 Location of peripheral cameras
....
"' gg
± ., a,
The four peripheral cameras are located in the ra­
d iator grille, in the luggage compartment lid and
on both exterior mirrors¢
fig. 139. Make sure
that the lenses are not covered by deposits or any
other obstructions as this may impair the system.
For information on cleaning, see ¢
page 306.
In the Surrounding mode, black corners are
shown in the vehicle silhouette. Objects in these
areas are outside of the camera's field of view
and are not detected.
The accuracy of the orientation lines and the blue
surfaces is reduced if the adaptive ai r suspen­
sion/sport* is faulty, if the vehicle is lifted or if
the
Dynamic mode is activated ¢ page 111.
A WARNING
-Always read and follow the applicable warn­
ings
¢&. in General information on
page 115.
-If the position or the installation angle of a
camera was changed, for example after a
120
collision, do not continue to use the system
for safety reasons. Have it checked by an au­ thorized Audi dealer or authorized Audi
Service Facility .
- Keep in mind that the image in the display is
incorrect if the exterior mirror housing has
been moved out of place.
- Use the
Rear mode and the Corner view
( rear)
mode only when the luggage com­
partment lid is completely closed . Other­
wise the image in the disp lay w ill be distort­
ed.
- The vehicle surroundings are shown using
the camera images. The vehicle image is
shown by the system. Objects and obstacles
above the camera are not displayed .
- Camera lenses enlarge and distort the field
of vision. The objects appear both altered
and inaccurate on the screen.
(D Note
-Always read and follow the applicable warn­
ings
¢ (Din General information on
page 115.
-The Infotainment disp lay shows the direc­
tion in which the rear of the veh icle is travel­
ing based on the steer ing wheel angle. The
front of the veh icle swings out more than
the rear of the vehicle. Maintain plenty of
distance so that an exterior mirror or a cor­
ner of the vehicle does not collide with any
obstacles.
@ Tips
If
the 8/IT;M/c:5 symbol appears in the dis­
play and the respective disp lay area is grayed
out, then the power exterior mirrors were
folded in or one of the doors/luggage com­
partment lid was opened .
