2014 AUDI RS7 SPORTBACK cruise control

88 Audi adaptive cruise control and braking guard
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray . Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
({) Tips
-You can cancel the braking with increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.
- Braking guard error messages
¢page 88.
- Keep in mind that braking guard can
brake unexpectedly . Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury.

Audi active lane assist
Active lane assist
Description
App lies 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
d river can over ride the correct 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 wheel. 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 equ ipped with Audi adap­
tive cruise control*, the corrective steering
will be more specific in regard to the driving
situation . In addition to the lane marker lines,
the system can also take into account other
objects such as guard rails . If they are detect­
ed i n close prox imity to the veh icle, Audi ac­
tive lane ass ist helps prevent the vehicle from
driving too close to them . There 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 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. Always keep your
hands on the steering wheel.
- Corrective steer ing may not occur in cer­
tain situat 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 ional ly as
lane marker lines . As a res ult, correct ive
steer ing may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light shining
into the camera. T his can result in act ive
lane assist not detecting the lane marker
lines or detect ing them incorrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the co rrective steering alone may
not be eno ugh 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 conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning.
Using act ive lane assist under these con­
d itions may increase the risk of a crash.

(dynamic). The goal is a high level of agility
and ability to accelerate on curves. The vehicle
is very responsive to steering.
Curve light*
The curve light adapts to driving on curves.
The pivoting action and the lighting are also
adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfo rtable to sporty, depending on
the drive se lect mode . Adaptive cruise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound
The sound of the engine is adapted to these­
l ected mode and ranges from subtle to sporty.
(D Note
-Make sure there is enough clearance
above and below the vehicle when park­
in g. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the veh icle down at the running
surface of the tires, which is the outer
circumference. Securing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change during transport. The vehicle
may not be secured sufficiently if this
happens.
(D} Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynamic modes.
- Se lecting the
Dynamic mode results in
spo rty shifting characteristics. The S
gear position engages automatically .

-In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the engine. This does not indi­
cate a problem.

Level control running

activate the parking brake and move the
selector lever to P.
- Power is sti ll transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when changing the selector lever pos ition
wh ile the vehicle is stat ionary and the
engine is running .
- Never shift into
R or P wh ile driving .
- Before driv ing down a steep slope, re -
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when dr iv ing
down a hill. Constant braking causes the brakes to ove rheat and substant ially re­
duces braking performance, increases
braking distance or ca uses comp lete fail ­
vre of the brake system .
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in place with the brake pedal or parking
brake.
- Never hold the vehic le on an incline with
a slipping clutch . The clutch opens auto ­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a dr iver message appears
~ page 108 when the clutch is overload­
ed .
- If the engine must remain running, never have any driv ing position engaged when
check ing under the hood.
M ake sure the
selector lever has secure ly engaged and
is locked in P with the parking bra ke set
¢ page 213 . Otherwise, any increase in
engine speed may set the vehicle in mo ­
t ion, even with the park ing brake ap­
plied.
(D Note
- When stopping on an incline, do not try to hold the vehicle in place by pressing
Aut omat ic Tr ans missio n 107
the acce lerator pedal while a d riving gea r
is se lected. This can cause the transmis­
sion to ove rheat and can damage it. Acti ­
vate the parking brake or press the brake peda l to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en­ gine is stopped and the selector lever is
in N will damage the transmission be­
cause

Audi pre sense Preventative passenger
protection
App lies to veh icles: with Audi p re se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The funct ions descr ibed depend on equipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli ­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof* : the
windows and the sunroof* close leaving a
small open gap .
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Audi drive select*: the deploy­
ment time is adapted in Dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the limits of the system, the likelihood of a colli­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered:
- Braking guard
¢ page 87
-Tightening the safety belts
- Closing the windows and the sunroof* ( leav-
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end col lision with the vehicle
coming from behind is also calculated. If the
Audi pre sense 187
risk of a collision is detected, the following
functions can be triggered:
- Tightening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Aud i pre sense rear .
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ate ly to have the malfunction corrected.
A WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks . This will increase
the risk of a coll is ion and serious personal
injuries .
- The sensors cannot always detect all ob­ jects. This increases the risk of a colli­
s10n .
- Aud i pre sense does not detect people or
an imals or objects that are crossing the
veh icle's path
¢page 81.
-The radar sensor's v is ion can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they may not be detected at all.
Q) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.
