Th e d istance at wh ic h the Adaptive Cruise Control fo llows a vehicle in

For example, if the interval DI STA NCE 3 is set, a vehicle in front is
followed at a time interval of 1.8 seconds.
For a speed of 50 mph (80 km /h ) this would be equ ivalent to a
distance of 131 feet (40 m ete rs) to the veh icle in front .

Adaptive Cruise Control -
----------------
In certain situations, the braking power of the Adaptive Cruise
Control is not enough to maintain an adequate distance to the vehicle
up ahead. In these situations, the Adaptive Cruise Control calls the
driver to take action.
The
driver intervention prompt alerts you visually and audibly to take
over.

• Th e text
DISTANCE! appears in the status line.
• The indicator light
c:::>uuc:::> in the speedometer blinks red.
• A warning tone sounds .
[I) Tips
• If the Adaptive cruise control initiates braking, the hydraulic brake
system is under pressure . Therefore, the brake pedal distance is
shorter and the pedal "feels" harder .
• Adaptive Cruise Control is switched
off after pressing the foot­
brake. The speed saved up this point can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever=>
page 124, "Turning Adaptive Cruise Control off
temporarily".
• If you use the accelerator to go faster than the speed of the
vehicle ahead of you, the
driver intervention prompt will not be
accompanied by a warn ing s ignal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch
off .•

General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits that are also related
to radar sensor range and sight distance. In some situations ACC may
reac t unusually or late from the driver's poin t of view . Therefore,
always be attentive to what is happen ing around you and a lways be
ready to intervene, if necessary:

Audi lane assist -________________ lff'II
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:
• Th ere 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.
• Th e vehicle's speed is below the speed needed to activate it, which
is about 40 mph (65 km/h) .
• Th e lane is narrowe r than about 8
ft. (2.5 m), or wider than about
16 ft. (5 m).
• 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 fo llowing messages appears on the
display:
Audi lane assist not available: currently no sensor vision
Thi s message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• Th e exte rior side of the camera viewing window=>
page 134,
fig. 127 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog disappears before turning lane assist on
again.
• Th e system was unable to detect boundary lines over an extended
period of time due to road conditions (such as snow-cove red lanes).
Do not turn lane assist on aga in until the lines can be more easily

-Select: Function button [CAR ]> Systems *> Audi lane

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 warn ing will occur earlier. If you approach the
boundary line at a very sha rp angle, the warn ing will occur just befo re
a wheel touches the line.
Medium : In this setting, the warning time adjusts to the characteris­
tics of the road and the vehicle speed. The wa rning occurs later fo r
curves and occurs earlier for straight stretches of road . The warning
occurs later on narrow roads than on wide ro ads.
Late : This setting warns the driver when a wheel dr ives over the
detected lane boundary line.

The detection~ page 138, fig. 131 of the radar sensor detection
area is made up of :
• the approach area (light green area)
(D, about 230 feet (70 m)
behind the vehicle, and
• the "blind spot" (dark green area)@.
The radar sensors cover the adjacent left and right lanes. Other lanes are
not cove red by the radar sensors.
rn Tip s
Side assist does not measure act ual lane width. The system assumes
a fixed lane w idth. Detection in the left and right lanes is based on
this assumed lane w idth. When driving on narrow roads or when
driving to the left or right of the center of a travel lane, it is possible
that vehicles will be detected that are
not in the lane next to the lane
you are using~
page 143. •
Applie s to ve hicl es: w ith s id e a ssist
Operation
Side assist compares the distance and difference in speed of detected
vehicles with the speed of your vehicle . Whenever the difference in
speed and distance is registered as notab le if you were to change
lanes, a signa l light appears on the respect ive m irror .
The signa l can light up if you are passed by a vehicle or if you are
passing another vehicle.
If you pass another vehicle slowly (d ifference in speed less than 9
mph, or 15 km/h) , the signa l light will come on as soon as the other
vehicle is in your blind spot and is detected by side ass ist . When the
difference in speed is greater, the signal light wi ll not come on. •

pp lies to ve hicles : w ith side assist
Informational and alert stage signals
S ide assis t has two signa l st ages:
• the informational stage signal, and
• t he ale rt stage signal.
S ide assist helps you by using the appropr iate s ignal stage,
depending on whether or not you have activated the turn signal, and
thus have indicated that you are or are not changing lanes .
Informat ional stage signal
As long as you have not activated the turn signal, side assist informs
you of detected vehicles that are registered as being in a notable loca­
tion if you were to change lanes . Wheneve r the detected vehicle 's
difference in speed and distance is registered by side assist as
notable, the signal l ight on the respective m irror produces muted
illumination .
Th e br ightness of the info rmationa l stage signal is designed no t to be
as intense, so that it does not interfere w ith your v iew of the road
when you are driving and have no in tention of chang ing lanes. When
you look in the outside mirror, you can clearly see the informat ional
stage signal.
Alert stage signal
Whe n you act ivate the tu rn s ignal, a nd side assist has de tected a
vehicle in a notable location on that particular side, the signal light on
this side mirro r flashes b rightly. The repeated brief and bright
flash ing of the alert stage signal reminds you to carefully check
traffic to the rear in the outside mirror and over your shoulder, so t hat
you can safely complete the lane change~
