& 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. •

Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance program is
a combined speed and distance control system.
Fig. 129 Front
bumper: Position of
radar sensor
Any speed between about 20 mph (30 km/h) and about 95 mph
(150 km/h) can be set and he ld with the Adaptive Cruise Con trol. The
system also regulates a pre-set distance from the vehicle ahead
within the limits of the system described.
Driving can be more relaxed, particularly on long trips on interstates
or on other highways that are generally straight.
How does it work?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column::::> page 137, "How is the speed stored?" and
=> page 140, "How is the distance (time interval) set?".
Con tro ls and eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 142, "Driver information" .
What is important for you to know
The Adaptive Cruise Control is set with system -specified limits, that
is, as a driver, you will have to adjust the speed and distance to the
vehic le ahead in some instances=> page 146, "Driver intervention
prompt" and=> page 147, "System limita tions".
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury .
• Never drive at speeds that are too high for traffic , road and
weather conditions.
• Never follow the vehicle in front so closely that you cannot stop
your vehicle safely. The Adaptive Cruise Control cannot brake the
vehicle safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 25% of the vehicle's maximum braking ability,
the automatic braking function cannot bring the vehicle to a stop.
• Never use Adaptive Cruise Control on roads where you cannot
drive safely at a steady speed, including city, stop-and-go or heavy
traffic, on winding roads or when road conditions are poor (for
example, on ice, gravel , in fog , heavy rain or on wet roads that
increase the risk of hydroplaning).
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray. This can result in vehicles driving ahead being inade ­
quately detected or, in some circumstances, not detected at all. If
necessary , take action yourself! ._

Audi lane assist
Lane assist
Applies to vehic les : w ith lane assist
Description
Lane assist helps you keep your vehicle in your lane.
Lane assist uses a camera to detect lane boundary lines. If the
system detects that your vehicle is about to leave a lane boundary
line, the steering wheel
vibrates to alert the driver . If lane assist
de tects boundary lines on both sides of the vehicle's lane, the
system enters active standby mode, which is indicated by the green
indicator light /: on the instrument cluster.
If the system is in active standby mode and the turn signal is acti­
vated before driving over the boundary line, the warning does not
occur since the system allows for intentional lane changes.
The system is designed for driving on freeways and expanded high­
ways and thus works only at speeds of 40 mph (65 km/h) or more.
& WARNING
• Lane assist will not keep your vehicle in your lane. The system
only warns the driver when the vehicle is leaving the lane . The
driver is always responsible 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 shining into
the camera lens. This can cause lane assist to fail to detect
boundary lines. •

Audi lane assist -
----------------
, Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warning. This can be due to the
following:
• There are no boundary lines, or there is only one boundary line
present .
• The boundary lines are not detected (e.g. due to snow, dirt, wet
conditions or light shining into the camera lens).
• More than two boundary lines (such as at construction sites) are
located in the vehicle's lane.
• The vehicle's speed is below the speed needed to activate it,
which is about
40 mph (65 km/h).
• The lane is narrower than about
8 ft. (2.5 ml, or wider than about
16 ft. (5 ml.
• The curve is too sharp.
Notes on the instrument cluster display
When the lane assist turns off automatically, the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lane assist not available: Currently no sensor vision
This message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• The exterior side of the camera viewing window=>
page 150,
fig. 148 is covered with dirt or ice. Clean this part of the windshield.
• The camera viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• The system was unable to detect boundary lines over an
extended period of time due to road conditions (such as snow­
covered lanes). Do not turn lane assist on again until the lines can
be more easily detected.
Audi lane assist not available
Controls and equip ­
ment A temporary malfunction is preventing
lane assist from operating .
Try turning on lane assist again at a later time.
Audi lane assist: system fault
The system should be checked by an authorized Audi dealer or other qualified workshop.
[ i] Tips
• Make sure that the camera viewing window=> page 150, fig. 148
is not covered by stickers or similar objects .
• Always keep the camera viewing window clean. This can usually
be done by operating the windshield wipers. •

Setting the warning time
Early: This setting warns the driver before a wheel touches the
detected lane boundary line. The warning depends on the vehicle's
angle as it approaches the boundary line . If you approach a
boundary line gradually, the warning w ill occur earlier. If you
approach the boundary line at a very sharp ang le, the warning will
occur just before a wheel touches the line.
Adaptive : In this setting, the warning time adjusts to the character ­
istics of the road and the vehic le speed. The warning occurs later for
curves and occurs earlier for straight stretches of road . The warning
occurs later on narrow roads than on wide roads.
Late: This setting warns the driver when a whee l drives over the
detected lane boundary line .
Setting the steering wheel vibration
When adjusting the steering wheel vibration, the steering wheel
vibrates so that you can check the intensity you have set.
[ i ] Tips
• When making the adjustment, lane assist is not activated. The
steering wheel vibrates briefly only to assist you in changing the
setting .
• Your settings are automatically stored and assigned to the
remote control key being used.•
