The different symbols for the time intervals appear if you change the

Th e text message ... (three white dots) appears if a setting cannot be
implemented with the operating lever. The following are possible
reasons:
• If you pull the control lever towa rds you to resume speed but no
requested speed was set .
• If you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If you push the lever up to increase (or down to reduce) speed and
this speed is outside the range from 20 to 95 mph (Canada mode ls:
30 to 150 km/h) .
ACC functionality Limited
The text message ACC functionality limited appears when the ACC
system does not detect any objects over an extended time period. For
the time being, the distance to veh icles up ahead is not being
Controls and equip
ment Safety first
controlled
. The ACC system is not switched off, so increased alertness
is required. The following may be reasons for the text message ACC
Functionally limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
reacting correctly, to vehicles traveling ahead.
• It is possible that you are driving on a road with very light traffic
without anything at the s ide of the road (e .g . guard rails, traff ic s igns,
trees). As soon as a vehicle is detected by the system again, it returns
t o its contro l range and the text message disappears.
The ACC sensor is located in the r ight front trim grille=>
page 122,
fig. 112. If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operat ion .
ACC not available
The text message ACC not available appears, for examp le, if the
t empe rature of the brakes is excessive. Adaptive cruise control is
temporarily not available. A warning tone sounds as a rem inder .
ACC not available!
The text message ACC not available! appears in the event of a
ma lf unct ion. Adaptive cruise control is turned off. A warn ing tone
sounds as a reminder . Have the system inspected by a qualified deal
ersh ip.
ACC sensor blocked !
The text message ACC sensor blocked! appears when the ACC system
can no longer guarantee safe detection of objects. Adaptive cruise
control is turned off. A warning tone sounds 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 Functionally
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is d irty or blocked (e.g. leaves, snow).
The sensor should be cleaned to restore prope r sensor funct ion

• The text
DISTANCE! appears in the status line .
• The indicator light in the Instrument cluster blinks red .
• A warning tone sounds.
[I) Tips
• If the adaptive cruise control initiates brak ing, 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 press ing 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 126, "Turning adaptive cruise control off
temporarily ".
• If you use the accelerator to go faster than the speed of the object
ahead of you, the
driver intervention prompt will not be accompa
nied by a warn ing signal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch off.•

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cru ise contro l is governed by physical and
system-specified limits. Also, under certain circumstances, the ACC
system may react unexpectedly or late from the driver's point of view.
Therefore, a lways be attentive and intervene, if necessary:
• when driving around curves=>
page 134
• when vehicles in front are not in line with your vehicle=> page 134
• when other ve hicles are changing lanes=> page 134
• when other veh icles are difficult to detect=> page 135.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . This can result in vehicles driving ahead being inadequately
detected or , in some circumstances , not detected at all. If neces
sary, take action yourself!•

& WARNING
• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s
danger of accident!
• Side a ssist cannot detect vehicle s
in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius le ss 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 changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

Setting the signal brightness on the
outside mirror
The signal brightness con be set in the radio or MM!*.
- Select: Function button [CAR ]> Audi side assist -lamp.
- Rotate the control knob to adjust the displayed brightness
of the signal light on the outside mirrors.
The brightness of the signal light for both the informational and alert
stages is automatically adjusted to ambient light conditions. In addi
tion, you can adjust the
basic brightness separately, via the bright
ness funct ion.
While making the adjustment, the new brightness setting is displayed briefly. The brightness displayed is that of the informa
tional stage signal. The alert stage signal brightness is linked to the
informational stage signal brightness.
The informat ional stage signal brightness should be adjusted so that
you notice the signal illumination when you look in the outside
mirror, but not when you look forward through the windshield.
In very dark or light surroundings, the automatic brightness setting
adjusts signal light brightness to maximum or minimum intensity , as
needed. In circumstances such as these, you may not notice any
change in the brightness on the outside mirror when adjusting the
basic brightness.
You may not notice the change until lighting conditions are normal
again.
