6 mph (10 km/h) and press the brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func
t ion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary. Be
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P.
Otherwise, the vehicle could inadvertently
roll away .
- The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key.
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com
partment.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment

such as the power windows could be operat
ed. This can lead to serious injury.
- Never leave children or persons requiring as
sistance unattended in the vehicle. The
doors can be locked using the remote trans
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex
posed to very high or very low tempera
tures.
0 Note
If the engine has been under heavy load for
an extended period, heat builds up in the en

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 126 In strument cluste r: appro ach warning
Braking guard uses a radar sensor. It also func
tions within the limits of the system when adap
tive cruise control is switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes suddenly
or if your own vehicle i s traveling at a high speed
and approaching a vehicle up ahead that is mov
ing more slowly . Braking guard does not react if
it cannot detect the situat ion.
The system advises you of variou s 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 indic ator light .
in the display comes on.
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is given, it may only be pos
s ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the display will warn you about the danger
¢fig. 126. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, braking guard will intervene
by braking and the message
Braking guard: Acti
vated
will appear.
l) Thi s is no t a vail able in som e coun trie s.
112
- If a collision is imminent, the system will first
provid e an
acute warning by briefly and sharply
app ly ing the b rakes.
- If you do not react to the acute warning, brak
ing guard can brake within the limits of the sys
tem . This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete deceleration shortly be
fore a collision ll.
- If the braking gua rd senses that you are not
braking hard enough when a collision is immi
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio/MM
I*
¢ page 113 , Settings in the radio/MM!* .
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries . The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always intervene. The driver is always respon
sible for braking at the correct time .
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al
ways keep the safe and legal distance be
tween your vehicle and vehicles up ahead .
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approach ing a stopped vehi
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf
fic) .
- 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 other 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 detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
- You can cancel the braking that is initiated
by the system by braking yourse lf, by accel
erating noticeably or by swerving.
- Braking guard error messages
¢page 113 .
-Keep in mind that braking guard can brake
unexpected ly. Always secure any cargo or
objects that you are transporting to reduce
the risk of damage or injury.

Improper reliance on the side assist system
can cause collisions and serious personal in
jury:
- Never rely only on side assist when chang
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
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 authorized
Audi Service Facility check their function.

Airbag system
(D Tips
If the weight-sensing mat in the front passen
ger seat detects an empty seat, the front air
bag on the passenger side will be turned off,
and
PASSENGER AIR BAG OFF will stay on.
Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing , remov
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system and prevent that system from working properly in a collision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer
ing wheel horn pad or airbag cover or the in
strument panel or modify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov
ering the airbag units.
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois
tened 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 deploy and protect properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or electrical system (in
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
164
who has the training and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your au
thorized Audi dealer or qualified workshop .
- 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately 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 replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag compo
nents must be performed by qualified work
shops only. Make sure that any airbag serv
ice action is entered in your Audi Warranty
& Maintenance booklet under AIRBAG RE
PLACEMENT RECORD.
- In accidents when an airbag is deployed, the
vehicle battery separates the alternator and
the starter from the vehicle electrical sys
tem for safety reasons with a pyrotechnic
circuit interrupter.
- Work on the pyrotechnic circuit interrupt
er must only be performed by a qualified
dealer - risk of an accident!
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.

Intelligent Technology
electrical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg ate the limits of physics . Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica
tor light (•) appears
r=:; page 33.
What you should know
The highest priority is given to maintaining start
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrical energy is required, but only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In this instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no
tice energy management actively regulating the
distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca pability over a longer period. Some of the con
venience functions may not operate, such as the interior lights or the power seat adjustment . The
convenience functions will be available again
when you switch on the ignition and start the en
gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI" functions,
the battery is being discharged .
If starting capability is jeopardized due to energy
consumption, a message appears in the radio or MMI* display . The message indicates that the
system will be switched off automat ical ly in a
196
moment. If you wish to continue using the func
tions, you have to start the engine .
With the engine running
Although electrical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en
ergy is being generated and a great deal con
sumed and the battery's state of charge is not
optimal.
To bring the energy balance back into equilibri
um, consumers which require especially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re
quire a great deal of energy. If you notice, for ex
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo
rarily cut back or switched off . These systems will
be available again as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not a
cause for concern. By increasing engine idle
speed the additional energy required is generat
ed and the battery is charged.
