Rest recommendation
General notes
Applies to: vehicles with rest recommendation
Under certain conditions, the system can detect
that the driver needs to take a break.
At the beginning of a trip, the system monitors
the driver's general steering style. Using this as a
reference, the system continuously compares the
current steering input at speeds of between 60
km/h and 200 km/h. If the evaluation of the
steering input implies a lapse in the driver's
con­

centration,
the system will then recommend a
break
^>page
111,
Instrument cluster display.
The rest recommendation function is designed
for journeys on motorways and major roads.
System limitations
The rest recommendation function may misinter­
pret the steering input in certain driving situa­

tions,
such as the following:
- On twisty roads.
- On rough roads.
- In poor weather.
- During performance driving.
- When the driver's attention is distracted.
Resetting the system
The system is automatically reset if
you...

- switch off the ignition.
- release the driver's seat belt and open the driv­
er's door.
- drive slower than 60 km/h for a while. If you
subsequently increase your speed again, the
system will reevaluate the driving style.

/\
WARNING
- Never drive when you are
tired.
As a driver
you are always responsible for ensuring that
you
are
fit to drive.
- On
Long
journeys, make sure to take
quate breaks at regular intervals.

ade-

- The system cannot always tell if
you
need a
break.

must be kept free of stickers, deposits and any
other substances which could impair the function
of the adaptive cruise control and pre sense front
systems. Notes on cleaning
^>page
312. Please
bear the above in mind if technical modifications
are made to the front of the vehicle.
The functionality of the adaptive cruise control or
pre sense front systems is restricted in certain
situations:
- Vehicles cannot be detected until they are
with­

in the range of the sensor
^>page
111,

Fig.
100.
- The ability of the system to detect vehicles in
front is Limited when they are too close, travel­
ling out of line, or moving into your lane.
- Vehicles that are not clearly discernible, e.g. a
motorcycle or cyclist travelling in front of you
and vehicles with high ground clearance or a
protruding
load,
are often identified late or are
not detected at all.
-When driving through bends
opage
112.
-When vehicles are stationary
^page
113.
A WARNING
Please always direct your full attention to the

road,
even when you are using adaptive cruise

control.
It is always the driver who is respon­
sible for pulling away safely and maintaining
a safe speed and distance from other vehicles.
The purpose of the adaptive cruise control is
to assist the driver. The driver must always in­
tervene manually to avoid an impending
colli­

sion.
As the driver you are always responsible
for braking in good time.
- For safety reasons, the adaptive cruise
con­

trol must not be used on roads with a lot of
bends or in poor weather or difficult or slip­
pery driving conditions (such as ice, fog,
loose grit or gravel, heavy
rain,
etc.) - risk of
accident!
- When you take a turn-off, drive along a mo­
torway exit lane or pass through roadwork
sections, please temporarily switch off the
adaptive cruise control system. This is to en­
sure that the vehicle does not accelerate to
the cruising speed in such situations.
- The adaptive cruise control system will not
brake the vehicle automatically if
you
rest
your foot on the accelerator pedal. Resting
your foot on the accelerator pedal overrides
the speed and distance control function.
- The adaptive cruise control does not react to
pedestrians, animals or crossing or oncom­
ing traffic.
- Reflecting objects, such as crash barriers,
the entrance to a tunnel, heavy rain or ice
can impair the function of the radar sensor.
© CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensor. This can impair the effective­
ness of the adaptive cruise control. Have the
systems checked by a qualified workshop.

Audi pre sense front
Description
Applies to: vehicles with Audi pre sense front
In certain situations and at certain speeds, pre
sense front can warn you if there is a danger of
collision with crossing
pedestrians1^
or station­
ary, parked and moving vehicles, and can apply
the brakes if necessary.
Pre sense front will not react if it is not in a
posi­

tion to detect the danger.
In conjunction with pre sense basic, the following
functions may be initiated, depending on how
fast the vehicle is travelling:
- Activation of reversible front seat belt tension­

ers.

-Automatic closing of windows and panorama

Fig.
113 Instrument cluster: Collision warning
Advance warning/acute warning
The system can give visual and audible warnings
if it detects a dangerous situation. An advance
warning can be given if:
- A vehicle in front brakes suddenly.
- Your own vehicle approaches a stationary
vehi­

cle at
a
speed of approx. 30 to 85 km/h.
- Your own vehicLe approaches a much slower ve­
hicle travelling in the same direction or
a
sta­
tionary vehicle ahead at
a
speed of more than
approx. 30 km/h.

x)
Not available on vehicles for some markets.
- A crossing
pedestrian15
moves into your lane
and you are travelling at a speed of approx. 30
to 65 km/h.
If this warning is given, you may need to take
evasive action or brake hard to avoid a collision.
The driver message Audi pre sense
| Sj
^>Fig.
113
and a warning tone draw your attention to the
danger.
In the event of an impending collision with a ve­

hicle,
an acute warning is also given in the form
of
a
brake jolt. If
you
do not respond to the acute

warning,
pre sense front
can,
subject to general
system limitations, apply the brakes with in­
creasing brake force, in order to slow the vehicle
down and take the impact out of
a
potential
colli­

sion.

Automatic braking
Pre sense front can initiate an automatic brake
application at certain speeds just before a
colli­

sion:

- At up to 85 km/h if vehicles are stopped.
- At any speed if moving or stopping vehicles are
detected ahead.
- At up to approx. 65 km/h if pedestrians are

crossing15.

Automatic brake pressure increase
If pre sense front detects
that
you are not brak­
ing hard enough in the event of an impending

collision,
it will increase the brake pressure, de­
pending on the situation and speed:
- At up to 85 km/h if vehicles are stopped.
- At any speed if moving or stopping vehicles are
detected ahead.
WARNING
The protection provided by pre sense front is
still subject to the prevailing physical limits.
It is a driver assist function and cannot pre­
vent
a
collision in every situation. The driver
must always intervene personally. As the driv­
er you are always responsible for braking in
good time. Do not let the extra safety

Audi active Lane assist
Description
Applies to: vehicles with Audi active lane assist
The active lane assist (lane departure warning
feature) uses a camera in the windscreen to de­
tect lane markings (subject to general system
limitations). If
you
approach one of the detected
lane markings, the system corrects the steering
to warn you that the vehicle might be about to
cross one of the markings. You can override this
steering input at any time. The steering wheel vi­
brates slightly if
you
cross a lane marking. The vi­
bration warning must be activated beforehand on
the infotainment system. The active lane assist is
functional when it detects a demarcation line on
at least one side of the lane in which you are driv­

ing.

As the system is designed for driving on motor­
ways and other major roads, it is only active

§
above a speed of about 65 km/h (may vary in dif-

£
ferent export markets).
r\i

A WARNING
- The system initiates a corrective steering in­
put to warn the driver that the vehicle is
about to leave the lane. As the driver you
are always responsible for staying in your
own lane.
- The system can assist you to keep the
vehi­

cle in the lane, however it is not capable of
driving on its own. Never take your hands
off the steering wheel.
- In certain situations, e.g. during heavy brak­

ing,
the system may not correct the steer­

ing.

- In certain circumstances, not all of the lane
markings may be detected by the camera. A
corrective steering input can only be
initi­

ated if the system detects a lane marking on
the side in question.
- Variations in the road surface or objects on
the road may be misinterpreted as lane
markings. In this case, the steering may be
corrected unexpectedly or not at all.
- The camera's view might be obstructed, for
example by vehicles travelling in front,
rain,

snow, a lot of water on the
road,
adverse
light
or
dirt on the windscreen. If this hap­

pens,
the active lane assist may not detect

Driver assist systems
the lane markings or may respond incorrect-

iy.

- In certain circumstances, for instance if
visi­

bility is poor, the setting for the steering in­
put may temporarily be switched from "ear­

ly"
to "late"
«.

- In certain driving conditions, such as ruts in
the road surface, adverse cambers or side
winds, the assistance provided by the steer­
ing correction may be insufficient to keep
the vehicle in the middle of the lane.
- For safety reasons, the active lane assist
must not be used in poor weather or in
diffi­

cult or slippery road conditions (such as ice,

fog,
loose grit or gravel, heavy
rain,
snow,
etc.) - risk of accident!
