not be detected. The sensor measures the distance to reflective
surfaces that must have a certain size. The system responds only
after the distance measurement has been made . If a measurement
is not possible, the system cannot respond and wil l not react to a
vehicle or something else up ahead.
O pen ro ad
When the road is clear, the Adaptive Cruise Control works like cruise
control. It main tains a constant target speed specified by the driver.
D riv in g in tr affic
If a slower vehic le driving ahead is detected, the Adaptive Cruise
Control dece lerates (within the limits of the system)::::;,
page 138,
"Driver intervention prompt" and::::;, page 140, "System limitations"
to its speed and after adjusting, tries to maintain the set distance
from the vehicle ahead . The vehicle may temporarily drive s lower
than the set speed while adjusting::::;,
& in "Description" on
page 127.
If the vehicle in front accelerates, Adaptive Cruise Control a lso acce l­
erates up to the speed that you have set.
Sit uation s re qui ring d rive r int erve ntion
In some situations you will have to use the footbrake to s low the
vehicle down in order to keep a safe distance from vehic le in front
of you or to avoid a rear -end collision. In this situation, a symbol
appears and a warning tone sounds::::;,
page 138.
P assing anoth er veh icle
If you move into the pass ing lane and no vehicle is detected ahead,
the Adaptive Cruise Control accelerates to the speed you have set
and ma intains it.
O ve rridin g ACC
You can increase your speed at any time by stepping on the acceler­
ator pedal. After you re lease the acce lerator pedal, the system
adjusts back down to the speed you previously set.

ment R
edu cin g s topping di sta nce
If the radar sensor detects that the distance to the vehicle ahead is
less than defined minimum distance, the brakes are automatical ly
prepared for emergency braking by the driver . The brake pads are
moved very c lose to the brake discs without actual ly braking the
vehic le. This brake assistant feature reacts more quick ly to the
driver's braking, and also works when Adaptive Cruise Control is off.
The stopping distance is reduced as a result of this advance brake
preparation. This function does not perform any emergency brak ing
maneuvers by itself; the driver must always app ly the brakes.
& WARNING
• Never r ely on the d istan ce control feature of ACC alone t o
p re vent re ar- end colli sio ns. Alwa ys be prep ared t o br ake and take
eva sive ac tion to a void colli sio ns and ot her acc ident sit uation s.
• Never allo w the clo sing sp ee d b etwe en you and other vehi cle s
to be so hi gh th at th e Ada ptive Crui se Control may not b e able to
s low your vehicl e safely . If clo sing spe ed i s too h igh , you must
a pp ly the brake s yours elf to reduce the risk of a rea r-end cras h.
[ i ] Tip s
Please note that the amount of acceleration the Adaptive Cruise
Contro l uses depends on the Distance setting selected . DISTA NCE 1
gives you acceleration that is dynamic and sporty . D ISTANCE 4, on
t he o ther hand, gives more moderate acce leration. For more infor ­
mation about the time intervals::::;,
page 133, "How is the distance
(time interval) set?" .
• Please note that if the Adaptive Cruise Control has begun braking
t he vehicle and the driver chooses to brake the vehicle additional ly,
the brakes may feel "hard". This is simply due to the pressure build ­
up of the initial braking .
• 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 pu ll the control lever _.,

tained. The ACC system is not switched off, and increased attention
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 again, ACC becomes
active again and the message disappears .
The 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
operation.
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 warning tone
sounds as a reminder. Have the system inspected by a qualified
dealership .
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 a lso 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 will also takes into consideration the outside
temperature and/or the windshield wiper operation.
The 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 blocked, clean the area to restore system
operation.
EPB activation
Th e text message EPB activation appears if emergency braking was
manual ly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Con trol is turned off . This is accompanied by a
warning tone.
Speed
The set speed in mph (Canada km/h) always appears when saving or
changing the speed in Adaptive Cruise Control~
page 130 , "How is
the speed stored?" and~
page 131 , "Changing stored speed".
Selector lever position!
The text message Selector lever position! appears when the
selector lever is moved to position
N. In this position, Adaptive
Cruise Control is not available. •

General information
The radar sensor has limits that the driver must know to
b e able to use AC C properly.
The Adaptive Cruise Control works within limits that are also re lated
to radar sensor range and sight d istance. In some situations ACC
may react unusually or late from the driver's point of view. There ­
fore, always be attentive to what is happening around you and
a lways be ready to in tervene, if necessary:
• when driving around curves=>
page 140
• whe n vehicles up front are not in line with y our vehicle
=>
page 141
• when other vehicles a re changing lanes => page 141
• when other vehicles are difficu lt to detect => page 141.
• when vehicles up ahead are not moving or obstacles are in your
travel lane=>
page 141
& WARNING
The radar sensor's function and range can be r educed by rain ,
sn ow and he avy spray. Moving vehicles up ahead may not be
promptly det ected or ma y not be det ected at all.
• Alway s pay careful attention to the traffi c situatio n a nd be
ready to intervene and be ready to take complete contr ol when ­
e ver ne ces sary . •

I Not ready: The yellow indicator light shows that the system is
turned on but unable to send a warn ing. This can be due to the
following:
• There are no boundary lines, or there is on ly 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 s ide of the camera viewing window=>
page 143,
fig. 144 is covered with dirt or ice. Clean this part of the windshield.
• The camera v iewing 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
A temporary malfunction is preventing lane assist from operating .
Try turning on lane assist again a t 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 143, fig. 144
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. •

Description
The side assist helps you when changing lanes.
AUDI
Fig . 146 Rear bumper:
Position of radar
sensors (not visible on
outside)
Fig . 147 Signal light
on the outside mirror -
driver's side
Side assist uses radar sensors (not visible on outside) ::::, fig. 146 to
help the driver check blind spots, and see what is happening in
traffic behind the vehicle::::,
page 148, fig. 149.
Signal lights are built into both outside mirrors::::, fig. 147. The
signal light on the left outside mirror assists when moving over into the left lane and the signal light on the right outside mirror assists
when moving over into the right
lane.
The signal light comes on to tell you that side assist has detected a
vehicle on that side and that the position of this other vehicle
should be taken into account if you were to change lanes. This is
called the
informational stage signal::::, page 148. The informational
stage signal is designed so that you notice it only when you are
looking in the outside mirror.
When you activate the turn signal and side assist detects a vehicle
in a notable location, the corresponding signal on the outside
mirror flashes briefly and brightly several times. This is the
alert
stage signal ::::,

T he system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause colli­
sions and seriou s per sonal injury:
- Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to c hange lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly.
• The radar sensor's
vision can be reduced or entirely blocked by
rain , snow, and heavy spray . This can result in side assist not
adequately detecting veh icles or , 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.
• Please note that side assi st indicates there are approaching
vehicles, or vehicles in your bl ind spot , only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km /h).
• S ide assist signal does not work around tight corners (turning
radiu s less than 328 feet, or 100 m l.
• Side assist is no replacement for the driver's full attention . The
d river alone is responsible for lane changes and similar driv ing
maneuvers. Always keep an eye on the d ire ction you are travel ing
and the relevant area around the vehicle .

Sensor detection area
Fig. 149 Schem ati c
illu str ati on : Sens or
d etec tio n area
The detection ~ fig. 149 of the radar sensor detection area is made
up of:
• the approach area !light green area)
0, about 230 feet (70 ml
behind the veh icle, and
• the "blind spot" (dark green areal@.
The radar sensors cover the adjacent left and right lanes. Other
lanes are
not covered by the radar sensors .
[ i ] Tip s
Side assist does not measure actual lane width . The system
assumes a fixed lane width. Detection in the left and right lanes is based on this assumed lane width. 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 wi ll be detected that are
not in the lane next
to the lane you are using~
page 153 . •
Ap plies to vehicl es: with side assist
Operation
Side ass ist 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 signal light appears on the respective mirror.
The signal can light up if you are passed by a vehic le or if you are
passing another vehicle.
If you pass another vehicle slowly (difference in speed less than 9 mph, or
15 km/h), the signal light will come on as soon as the other
vehicle is in your blind spot and is detected by side assist. When the
difference in speed is greater, the signa l light will not come on .•
Applies to vehic les : w ith side assist
Informational and alert stage signals
Side assist has two signal stages:
• the informational stage signal, and
• the alert stage signal.
Side assist helps you by using the appropriate signa l stage,
depend ing on whether or not you have act ivated the turn signal,
and thus have indicated that you are or are not changing lanes.
In fo rm ati onal stag e signal
As long as you have not activated the turn signa l, side assist informs
you of detected vehicles that are registered as being in a notable location if you were to change lanes. Whenever the detected
vehic le's difference in speed and distance is registered by side
assist as notable, the signa l light on the respective mirror produces
muted il luminatio n.
The brightness of the informationa l stage signal is designed not to
be as intense, so that it does not interfere with your view of the road
when you are driving and have no intention of changing lanes. .,,,
