particular seat.

T o avoid damage to the heating elements in the seats, do not kneel
on the seats or place heavy loads on a small area of the seat.

Please note that the weight of objects placed on the seat will also
be detected. This weight may be enough to cause the seat heater to

& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents 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.
• After the engine has been switched off, the radiator fan can
continue to run for up to 10 minutes -even with the ignition
switched off. It can also switch on again after some time if the
coolant temperature rises as the result of a heat buildup or if the
engine is hot and the engine compartment is additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

If a function is not present, a driver message appears.
No key identified
This message appears when the [STAR T) button is pressed if there
is no master key inside the vehicle or if the system does not recog
nize it . For example, the master key cannot be recognized if it is
covered by an object (e.g. aluminum brief case) which
screens the radio signal. Electronic devices such as cell phones can also inter
fere with the radio signal.
Press brake pedal to start engine
This message appears if you press the [ START) button to start the
engine and do not depress the brake pedal. The engine can only be
started if the brake pedal is depressed.
Engage N or P to start engine
This message appears when the engine is started if the selector
lever for the automatic transmission is not in the P or N position.
The engine can only be started with the selector in these positions.
? Key not in vehicle
This message appears along with the symbol if the master key is
removed from the vehicle with the engine running. It is intended to
remind you (e.g. when changing drivers) not to continue the journey
without the master key.
If the master key is no longer in the vehicle, you cannot switch off
the ignition after stopping the engine and you also cannot start the engine again. Moreover, you cannot lock the vehicle from the
outside with the key.
Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
is not in
P.
This message appears for safety reasons along with a warning
buzzer if the selector lever for the automatic transmission is not in
the P position when the ignition is switched off with the
[STOP)
button and the driver's door is opened. Move the selector lever to
the P position, otherwise the vehicle is not secured against rolling
away. You also cannot lock the vehicle using the locking button on
the door handle or using the remote key.
To engage steering lock, press and hold STOP button

& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injuries.
• Never resume the stored speed if the speed is too high for
prevailing road, traffic or weather conditions.
[ i ] Tips
When the system is turned off temporarily, the speed set at that
time is stored. •
- Push the slider switch again to the right 0 to increase
the distance by one step.
Reducing distance
Push the slider switch once to the left Q. The distance
currently set is shown for 3 seconds in the instrument

- Push the slider switch
again to the left Oto decrease the
distance by one step .
The distance at which the Adaptive Cruise Control follows a vehicle
in front is determined by
time intervals. A time interval to a vehicle
in front is established and maintained . This produces a speed
dependent interval. The higher the speed, the greater the safety
interval in feet (meters)

& WARNING
Following other vehicles too closely increases the risk of a crash
and serious personal injury .
• Following other vehi cles too closely , particularly at h igher
speeds increases the risk of colli sions and serious personal injury.
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic .
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffic , road , weather and
lighting conditions .
• Never rely on the distan ce control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other acc ident situations .
• Never allow the closing speed between you and other vehicles
to be so h igh that the Adaptive Cruise Control may not be able to
slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash .
• Always select a greater following distance to the vehicle ahead
on wet roads than on dry roads .

Audi braking guard
App lies to vehicles: with Adaptive Cruise Contro l
Description
Audi braking guard warns you of a possible collision with
a moving vehicle up ahead.
F ig. 180 Disp lay in t he
i nstrumen t cluster
The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 165 even when
the Adaptive Cruise Control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 154,
fig. 160. The system is intended to measure the distance to reflec
tive surfaces. If a measurement is not possible, the system does not respond.
When the measurement has been taken, the system can recognize a possib ly hazardous s ituation, for example, when a vehicle up
ahead in your lane of travel sudden ly brakes or when your own
vehic le is mov ing at high speed towards a much s lower vehic le up
ahead. As soon as the system senses that a possible collision with
t he vehicle up ahead can only be avoided by immediate full brake
application or by an avoidance maneuver, a warning appears.
The system has a default response time to be able to signal before a co llision occurs. This system response time is automatica lly
reduced if you acce lerate actively, for example to join a highway. Braking, transverse acceleration and the steering angle can lead to
a reduced system response time. The warning is deact
ivated if you
begin to overtake with full acceleration.
The system can make you aware of two different hazardous situa
t ions:
Distan ce
The distance warning is g iven if the system calculates that there is
not enough distance to the vehic le up ahead a period of more than
5 seconds . If the distance is less than 30 feet (9 meters) at 50 mph
(80 km/h), for example, an optical display comes on in the instru
ment cluster=> fig. 180.
If the vehicle ahead brakes sharply, Audi braking guard cannot help
you to avoid a co llision, even in the case of an immed iate response .
T ake immediate action to avoid the collision and increase the
distance to the vehicle up ahead .
Speed
If there is a much slower vehicle moving up ahead in your lane, or if
the vehic le ahead brakes sharply, the Aud i braking guard calculates
t he point from which a co llision can only be avoided by full braking
or by an avoidance maneuver. If a warning does sound, a possible
collision with the vehicle in front can only be avoided through an
evasive maneuver or by braking.
The warning is given in two stages :
• Pre-warning: A visual disp lay appears in the instrument cl uster
and a warning tone sounds.
• Acut e warning : If you do not respond to the pre -warning, the
second stage warning is given . A quick brake application helps to
direct your attention to the road and traffic situation .
Under heavy braking, the brake assistant::::>
