to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees) . As
soon as a moving vehicle up ahead is detected aga in, ACC becomes
active again and the message disappears.
Th e ACC sensor is located in the area under the front license plate.
If
the ACC sensor is dirty or blocked, clean the area to restore system
operat ion.
ACC not available
The text message ACC not available appears, for example, if the
temperature of the brakes is excessive. Adaptive Cruise Control is
temporarily not available. A warning tone sounds as a reminder.
ACC not available!
The text message ACC not available! appears in the event of a
malfunction. Adaptive Cruise Control is turned off. A warn ing tone
so unds as a reminder. Have the system inspected by a qualified deal­
ership.
ACC sensor blocked !
The text message ACC sensor blocked! appears when the ACC System
can no longer accurately detect vehicles moving up ahead in your lane
of travel. Adaptive Cruise Control is turned off. A warning tone also
so unds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC Functiona lly
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is dirty or blocked (e.g. leaves, snow) . The ACC sensor is located in the area under the front
license plate. If
the ACC sensor is dirty or bloc ked, clean the area to restore system
operation .
EPB activation
The text message EPB activation appears if emergency braking was
man ua lly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Control is turned off . Th is is accompanied by a
wa rning tone.
Speed
The set speed in mph (Canada km/h) always appears when saving or
changing the speed in Adaptive Cruise Control=:>

Selector lever position!
The text message Selector lever position! appears when the selecto r
lever is moved to position
N . In this position, Adaptive Cruise Control
is not available. •

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.
• A red vehicle is shown in the instru ment cluster display
=>
page 130, fig. 118.
• 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:

Aud i Lane assist
Lane assist
Applies to veh icles : 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 detects
boundary lines on both sides o f the veh icle's lane, the system enters
act ive standby mode, which is indicated by t he gree n 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 sinc e th e system allows for in tention al lane changes.
The system is designed for driving on freeways and expanded high­
ways and th us 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. •

lane boundary lines . -.,

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
detected.

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

& WARNING
• Imp roper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on s ide ass ist when changing lanes.
- Alway s che ck rear view mirror s to m ake sure that it i s safe to
change lanes.
• Side a ssist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssi st cannot detect vehicle s in time to alert you when
they approach from beh ind at very high speed, or fall drop back
very quickly .
• The radar sen sor's
v is ion can be reduced or entirely blocked by
rain , snow, and heavy spray . This can result in side as sis t not
adequately detecting vehicle s or , in some cases, not detecting
them at a ll. Alway s keep an eye on the dir ection you are traveling
and the rele vant area around the vehicle.
• Please note that side assist indicates there are approaching
vehicles , or vehicles in you r blind spot, only after you r vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal doe s not work around t ight corners (turning
radius les s than 328 feet , or 100 m).
• Side assist is no replacement for the driver 's full attention . The
driver alone is respon sible for lane change s and s imilar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.

• driving through curves=>
page 143,
• lanes are of different widths=> page 143. •
Ap plies to vehicles: w ith sid e assist
When driving through curves
Side assist cannot detect vehicles in curves with a turning radius of
less than 328 feet (100 m).
When driving through a curve, it is possible that side assist may
register a vehicle two lanes over, and the signal on the outside mirror
will light up.•

lanes away
Side assist's detection area is designed to cover lanes of standard
w idth to the left and rig ht of your travel lane, depending on whether
you drive in the center of your lane or closer to the edge.
If you drive in narrow lanes, side assist's detection area may also
include other lanes -especially if you tend to drive on t he edge of your
lane => fig. 137. Under these conditions, vehicl es can also be
detected that are two lanes away, and side assist then could switch
between the informationa l and warning stage signals .
When driving in very wide lanes, vehicles in the adjacent lane may not
be detected because they are not inside the detection area .•
