A WARNING
Imprope r use of the adaptive cruise con­
trol can cause collis ions, other accidents
and serious personal injuries.
- Pressing the
ISE TI button whe n driving at
speeds below 20 mph (30 km/h), will au­
tomat ica lly accelerate the veh icle to
20 mph (30 km/h), which is the m ini­
mum speed that can be set.
@ Tips
- If you switch the ignition or the adapt ive
cruise control off, the set speed is erased
from the system memory.
- The elect ronic stabilization control (ESC)
and the anti-slip-regulation (ASR) are au­
tomatically tu rned on when the adaptive
cruise control is turned on. Both systems
cannot be turned off if the adaptive
cruise control is turned on.

to pay close attention to traffic.

good judgment, and select a safe follow­
ing d istance for the t raff ic, road and

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 123 Instr ument cluster: approach warning
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adapt ive 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. Braking
guard does not react if it cannot detect the
s ituation.
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 collision . The indicator
light . in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly than you are or if it
brakes sharply. When thi s war ning is given,
it may on ly be possible to avoid a co llision
by swerving or brak ing sharp ly. The indicator
light . and indicator in the display will
warn you about the danger
r=.> fig. 123. You
wi ll also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in­
te rvene by brak ing and the message
braking
guard intervention
wi ll appear. ~

108 Audi adapti ve cruise control and br aking guard
- If a co llision is imminent, the system will
first provide an
acute wa rning by bri efly and
sharp ly app ly ing the brakes .
- If you do not react to the ac ute warning ,
braking guard can brake within the limits of
the system. This reduces the veh icle speed
in the event of a collis ion.
- At speeds under 20 mph (30 km/h), the sys ­
tem can in it iate a complete deceleration
s hortly before a collision
l) .
-If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force.
Which function s can be contr oll ed ?
You can switch braking g uard and the dis­
tance/approach warning on or off in the radio
or MM I c> poge 108, Settings in the radio/
MMI.
A WARNING
Lack of attention can cause col lisions, oth­
er accidents and serious persona l injuries.
The b raking guard is an assist system and
cannot p revent a col lis ion by itself. The
dr iver m ust always in tervene . T he d rive r is
always responsib le for br aking at the cor­
rect time.
- Always pay close attention to traffic,
even when the bra king guard is switched
on. Be ready to intervene and be ready to
take complete control whenever necessa­
ry. A lways keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works w ith in limits and
will not respond outs ide the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard wo rks only within
defined detection and range limits that
l ) Th is is not available in some c oun tri es.
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 veh icles up ahead may not
be prompt ly detected or may not be de­
tected at all .
- Reflective surfaces including crash barri­
ers or tunne l entrances may impair the
function of the radar sensor .
(D Tips
- You can cancel the braking that is in it iat­
ed by the system by braking yourse lf, by
accelerating not iceably or by swerving .
- Braking guard error messages
c>poge 109.
- Keep in mind that brak ing guard can
brake unexpectedly. Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury .

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
@ V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
© Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h)), the display in the exter io r mirro r
turns on as soon as the vehicle enters your blind spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
T he radar senso rs are des igned to detect the
left and right adjacent lanes whe n the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on
even though there is no ve hicle locat­
ed in the area that is cr itical fo r a lane cha nge.
For example:
- if the lanes are narrow or if your are driving on the edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to your
cur rent lane .
- if you a re driving through a c urve . Side assis t
may react to a vehicle that is one lane ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist fu nctions are limited .
Do not
cover the radar sensors c:;, fig. 127 with
stickers, depos its, bicycle wheels or other ob­
jects , because this will affect the funct ion. Do
not use s ide ass ist when tow ing a trail er. For
information on cleaning, refe r to
c:;, page 202 .
&_ WARNING
-Always pay a tten tion t o traffic and to the
ar ea around your ve hicl e. Side a ssist can ­
no t repla ce a driver's attention. The driv ­
er a lone is always respons ible fo r lane
cha nges a nd similar driving mane uvers.

-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
ch anging lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side ass ist cannot detect a ll vehicles un­
der all cond itions- dange r of accident!
- Please note that side assist indicates
ther e ar e approaching vehicles, o r
vehicles in your bli nd spot, o nly afte r
yo ur vehicle has r eached a driving speed
o f at least 19 mph (30 km/h).
- In certain s ituati ons, the system may not
f unc tion or its funct io n may be lim ited.
For example:
- if veh icles are approaching or be ing left
behind very quick ly. The display may
not turn on in time.
- in poor weather condit ions such as
heavy ra in, snow or heavy m ist .
- on very wide lanes, i n tight curves or if
there is a rise in the road surface .
Vehicles in the adjacent lane may not
be detec ted becaus e they are outside
of t he senso r range.
(D Note
The sensors can be displaced by impacts o r
damage to the bumper, whee l housing and
unde rbody. This can affect the system .

When do ing th is, there shou ld be good light
and weather conditions.
In t he MMI disp lay, objects or vehicles appear
