Audi adaptive cruise control and braking guard 99
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits 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 . Braking
gua rd 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 wi ll
not be able to avoid a collis ion. 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 th is warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 113. You
will a lso hear an acoustic signa l.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in-

tervene by braking and the message braking
guard intervention will appear.
- If a coll ision is imminent , the system will
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 within the lim its of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds unde r 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration
shortly before a collision
ll.
- 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 functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or M MI
c::> page 100, Settings in the radio/
MMI.
A WARNING
-Lack of attention can cause collisions, oth-
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The dr iver is
always respons ible for braking at the cor­
r ect time .
- Always pay close attention to traffic,
even when the braking guard is switched
on . Be ready to intervene and be ready to
take comp lete control whenever necessa­
ry. Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).

100 Audi adaptive cruise control and bra king guard
- Always remember t hat t he radar sens or
fo r the braking guard wo rks only within
defined detection and range limits that
may preve nt the proper detection of oth­
er v eh icles.
- The radar senso r's fu nction and range
can be reduced by rain, s now a nd heavy
spray. Mo ving v ehicl es u p ahead may not
b e promptly det ecte d or may not be de­
te cte d at al l.
- Reflective surfaces in cl udi ng c ras h barri­
ers or tu nnel ent ran ces may impair the
f unc tion of the r ad ar sen sor.
(D Tips
- You can cance l th e braking tha t is initiat­
ed by the system by braking yours elf, by
a cce lerati ng noticeab ly o r by swerving.

104 Audi side assist
-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly . The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may
be misinterpreted.

.. Press the button c> A in General informa­
tion on page 103
to switch the system on/
off. The LED in the button turns on when
side assist is switched on .
Adjusting the display brightness
Applies to vehicles: wit h Audi side ass ist
The signal brightness con be set in the radio
or MM!*.
.. Select: I CAR I function button > Audi side as­
sist.
.. Select: !CARI function button> Car systems*

The display brightness adjusts automatically
to the brightness of the surroundings, both in
the information and in the warning stage . In
very dark or very bright surroundings, the dis­ play is already set to the minimum or maxi­
mum level by the automatic adjustment. In
such cases, you may notice no change when
adjusting the brightness, or the change may
only be noticeable once the surroundings
change.
Adjust the brightness to a level where the dis­
play in the information stage will not disrupt
your view forward. If you change the bright­
ness, the display in the exterior mirror will
briefly show the brightness level in the infor­
mation stage. The brightness of the warning
stage is linked to the brightness in the infor ­
mation stage and is adjusted along with the
information stage adjustment.

110 Park assis t
Approaching another obstacle will result in
the distance warning sounding at the normal
volume aga in.
M alfunction s in the syst em
If a warning tone is audible for about five sec­
onds when you turn on the ignit ion, there is a
mal function in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist
system can function properly.
A WARNING
- Senso rs have dead spaces in which ob­
jects cannot be detected. Be espec ially
alert for small children and animals,
since they are not a lways detected by the
sensors.
- The acoust ic park ing system is not a sub­
st itute for the driver's own caut ion and
alertness . Ultimate responsib ility always
remains with the driver during park ing
and simi la r maneuve rs. Always watch
w here you are driving.
- You should always adjust the vo lum e and
frequency of the warning tones so that
yo u can easily hear the a co ustic distance
warning even if the radio is p laying, the
air-conditioner blower is on High or there is a high leve l of outside noise.
- Check the settings w henever anyone
e lse has driven the vehicle before you .
{[) Note
-Remember that low obstacles for wh ic h
-
a war ning has a lready been issued may
"d ive" below the system's sensing zone if
t h e veh icle is being backed up closer . In
th is case, the warn ing sound shutt ing off
does
not i ndicate that yo u have cleared
the obs tacle. Instead, impact is immi ­
nent.
- Objec ts such as trai ler hitches, c hains,
nar row posts or fen ces covered by a t hin
l aye r of paint may not a lways be detect -ed by the system
. They can still damage
your vehicle without warning.

c ially for small children and an imals. The
rear view camera cannot a lways detect
them, posing risk of an accident!
- Please note that objects not touch ing the
ground can appear to be further away
than they really are (for example, the bumper of a pa rked vehicle, a t railer
hi tc h, or the rear of a tru ck). In this case,
yo u should not use the help lines to he lp
with par king, which poses danger of an
accident!

for the adaptation has expired or the pro­
gram ming was unsuccessful. Repeat the
programming from step 3 on the controls
or se lect another distance from the radia­
tor grille.
9. If the garage door or other devices still
fail to be activated w ith the Homelink
control buttons after programming is
completed, it is possible that these sys­
tems might be working with a rolling code
instead of the normal fixed code.
A Roll­
ing code programming must be per­
formed

154 Airbag system
-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only once. After an airbag has been deployed,
it must be replaced with new replace- ment parts designed and approved espe­
cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­ rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for

186 Intelligent technology
to prevent excessive disc harge of the battery
and thus maintain starting capability.
Dynamic en ergy management
While the vehicle is be ing dr iven , dynamic en­
e rgy management distributes the energy gen­
erated accordi ng to the needs of the individu­
a l components . It reg ulates cons umption, so
that more electrical energy is not being used
than is being generated and ensures an opti ­
mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are li mited .
- If starting ab ility is threatened, the indi­
cator light(•) appears
¢ page 17.
What you should know
The highest priority is given to maintaining
starting capabili ty.
The battery is severely taxed in short-distance
d riving, in city traffic and during the co ld time
of year. Abundant e lectr ica l energy is re ­
qu ired, but only a little is generated. It is also
cr itical if the engine is not run ning and electri­
cal components a re turned on . In th is in ­
stance energy is being consumed but none is be ing generated.
It is in precisely these situations that you w ill
notice energy management actively regulat ­
ing the distr ib ution of energy.
Vehicle stands for an extended period If yo u do not drive your vehicle over a period
of severa l days or weeks, electrical compo­
nents are gradually cut back o r switched off .
This reduces energy cons umption and mai n­
tains sta rting capab ility over a longer period .
Some of t he conve nien ce f unctions may no t
ope rate, su ch as the in ter io r l ights o r the
power seat ad justment. The convenience
f u nctions will be avai lable again when you
switch on the ignition and start the engine . With the engine turned off
If you
listen to the radio, for examp le, w ith
t h e engine t urned off or use other M MI func ­
tions, the battery is being discharged .
If s tarti ng capab il ity is jeopardi zed d ue to en­
ergy consumptio n, the following warning ap­
pears in the MM I display:
Pl ea se start the engine soon or the syst em
will be turned off .
The warning indicates that the system will be
tu rned off automatically after 3 minutes . If
you w ish to continue using the funct ions, yo u
have to sta rt the eng ine .
With the engine running
Althoug h electrical energy is generated when
the vehicle is being dr iven, the battery can be ­
come discharged. This happe ns mostly when
li ttle energy is being ge ne rated and a g reat
deal consumed and t he ba ttery's state of
c harge is no t opt imal.
To b ring the energy bala nce back into equ ili­
br ium, consumers wh ich requ ire espec ially
lar ge amounts of ene rgy a re temporar ily cut
ba ck or sw itched off. Heat ing systems in p ar­
t icu lar require a great deal of energy . If you
notice, for examp le, that the heated seats * or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems w ill be available again as
soon as the e nergy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for concern. By increasing engine id le
speed the additional energy required is ge ner ­
ated and the battery is charged .
