.&_ WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injury.
- Setting short distances to the traffic ahead reduces the t ime and distance
available to br ing your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing distance for the traffic, road and
weather conditions .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
tro l key being used.

Audi adaptive cruise control and braking guard 93
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Instrument cluster: approach warning
Audi braking guard uses radar sensors and a
video camera. It also functions within the lim­
its of the system when adaptive cruise control
is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Audi brak­
ing guard does not react if it cannot detect
the situation.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to avoid a collis ion. The indicator
light
I i n the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov ­
i ng much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and indicator in the display will warn
you about the danger
c::> fig . 96. You will a lso
hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard will

intervene by braking and the message braking
guard intervention
will appear.
- If a coll is ion is imminent, the system wi ll
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake with increas ing
force within the limits of the system. This
reduces the vehicle speed in the event of a
collision.
- The system can initiate complete dece lera­
tion shortly before a collision
1>. Full deceler­
ation at high speeds occurs only in vehicles
with adaptive cruise control and side assist
(pre sense plus).
- If the Audi braking guard senses that you
are not braking hard enough when a colli­
sion is immi nent, it can increase the braking
force.
- The pre sense functions also engage when a
collision is imm inent
c::> page 185 .
Which function s can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or off in the
MMI c::> page 94, Settings in the MMI.
A WARNING
Lack of attention can cause collisions, oth­
er accidents and serious personal injuries .
The Audi braking guard is an assist system
and cannot prevent a collision by itself.
The driver must always intervene. The driv­
er is always responsib le for braking at the
correct time.
- Always pay close attention to traffic,
even when the Audi braking guard is
switched on. Be ready to intervene and
be ready to take complete control when ­
ever necessary. Always keep the safe and
legal distance between your veh icle and
veh icles up ahead.
- Audi brak ing guard works within limits
and will not respond outside the system
lim its, for example when approaching a

Audi lane assist
Lane assist
Description
Appl ies to vehicles: with lane assist
Lane assist helps you keep your vehicle in your
lane .
Lane assist detects lane marker lines within
the limits of the system using a camera in the
windshield. If you are approaching a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you
with a light vibration . Lane assist is operable
when the line marki ng the lane is detected on
at least one s ide of the vehicle .
The system will not warn you before cross ing
a lane ma rker line if you have activated the
turn signal. In t his case, it assumes tha t you
a re cha nging lanes intent ionally.
The system is designed for driv ing on free­
ways and expanded highways and thus works
on ly at speeds of 40 mph (65 km/h) o r more .
.&_ WARNING
-Lane ass ist will not keep your vehi cle in
yo ur lane. The system only warns the
dr iver w hen the vehicle is leaving the
lane . The driver is always responsib le 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 warnings that 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 or light shin ing
in to the camera lens. This can cause lane
a ssist to fa il to detec t bou ndary lines.

lowing :
- There is no lane boundary line .
- The relevant lane marker lines are not de-
tected (for example, markings in a construc ­
tion zone or because they are obst ructed by
snow, d irt, water or backlighting) .
- The vehicle's speed is below the speed need·
ed to activate it, wh ich is about 40 mph (65
km/h).
- The lane is narrower than about 8
