tained. The ACC system is not switched off, and increased attention
to the traffic situation is absolutely necessary. The followi ng 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 yo ur la ne of travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example , guard rai ls, traffic signs, trees). As
soon as a moving vehicle up ahead is detected aga in, ACC becomes

General information
The radar sensor has limits that the driver must kno w to
be a ble t o use ACC proper ly.
Th e Ad apt ive Cr uise Con trol works wi thin limi ts th at a re also rela ted
to radar sensor range and sight distance. In some situations ACC may react unus ually or late from the drive r's point of view. Therefore,
always be atte ntive to what is happe ning around you and always be
ready to interve ne, if necessary:
• when driving aro und curves ~
page 150
• when ve hicles up front are not in line wit h your vehicle
~ page 15 0
• when other ve hicles are changing lanes~ page 150
• when other vehicles are difficult to detect~ page 151
• when ve hicles up ahe ad are not mov ing o r o bst acle s ar e in you r
trave l lane ~

& WARNING
The radar sensor's function and range can be reduced by rain , snow
and heavy spray . Moving vehicles up ahead may not be promptly
detected or may not be detected at all.
• Always pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when
ever necessary .•

-Adaptive Cruise Control •m.____...,__ _____________ _
The Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 149 even when
the Adaptive Cruise Control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 138,
fig. 132. The system is intended to measure the distance to reflective
surfaces. If a measurement is not possible, the system does not
respond.
When the measurement has been taken, the system can recognize a
possibly hazardous situation, for example, when a vehicle up ahead in
your lane of travel suddenly brakes or when your own vehicle is moving at high speed towards a much s lower vehicle up ahead . As
soon as the system senses that a possible collision w ith the vehicle up
ahead can only be avoided by immediate full brake application or by
an avoidance maneuver, a warning appears.
The system has a default response time to be able to signal before a
collision occurs. This system response time is automatically reduced
if you accelerate actively, for example to join a highway . Braking,
transverse acceleration and the steering ang le can lead to a reduced
system response time . The warning is deactivated if you begin to
overtake with full acceleration.
Th e system can make you aware of two different hazardous situa
tions:
Distance
T he distance warning is given if the system calculates that there is not
enough distance to the vehicle up ahead a period of more than 5
seconds. If the distance is less than 30 feet (9 meters) at 50 mph (80
km/h) , fo r example, an optic al disp lay comes on in the inst rument
cluster=> fig. 151.
If the vehicle ahead brakes sharply, Audi braking guard cannot he lp
you to avoid a coll is ion, even in the case of an immed iate response.
T ake immediate action to avoid the collision and increase the
distance to the vehicle up ahead.
Speed
If there is a much s lower vehicle moving up ahead in your lane, or if
the vehicle a head brakes sharply, the Audi braking guard calculates
the point from which a collision can only be avo ided by full braking or
by an avo idance maneuver. If a warn ing does sound, a possible co lli
sion with the vehicle in front can only be avoided through an evasive
maneuver or by braking.
The warn ing is given in two stages:
• Pre-warning : A visual display appears in the instrument cluste r
and a warning tone sounds .
• Acute warning: If you do not respond to the pre-warning, the
second stage warni ng is given . A quick brake application helps to
direct your attention to the road and traffic situation .
Under heavy braking, the brake assistant=>
page 138 also helps you
benefit from maximum braking effic iency.
& WARNING
Inattention can cause collisions, other accidents and serious
personal injuries.
• Always pay close attention to the traffic , even when the Audi
braking guard is switched on. The Audi braking guard provides a
warning but does not brake the car for you. You must apply the
brakes yourself!
• Always keep the safe and legal distance between your vehicle
and vehicles up ahead.
• Audi braking guard works within limits and will not respond
outside the system limits, for example when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or
vehicle that has broken down in traffic).
• Always remember that the radar sensor for the Audi braking
guard works within defined detection and range limits that may
prevent the proper detection of other vehicles. _,.,

& WARNING (continued)
• The r adar sen sor's function and range can be reduced b y rain ,

• Always pay careful attention to th e traffic situation and be
ready to intervene and be ready to take complete control when
ever necessary.
• Refle cti ve surfaces including cr ash barriers or tunnel ent rances
may impair the function of the radar sensor .•

The system works at speeds faster than 19 mph (30 km/h) .
& 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 .

Side assist's detection area is designed to cover lanes of standard

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 the edge of your
lane => fig . 161. Under these conditions, vehicles can also be
detected that are two lanes away, and side assist then could switch

Messages in instrument cluster display
If side assist turns off automatically, the indicator light on the button

display :
Audi side assist not available: sensors blocked
The side assist sensors are built into the rear bumper on the left and
right (not visible on the outside)=>
page 154, fig. 152. To ensure
that you do not adversely affect the way side assist functions, foreign
objects (such as stickers or bicycle racks) should not be attached to
the area on the rear bumper where the sensors are located. If side
assist functions are adversely affected, you will see this message in
the instrument cluster display . Remove anything that may be
blocking the sensors.
If no vehicle is detected for a longer period of time while driving, side
assist will also switch off automatically.

If there is a temporary problem (such as the vehicle's battery charge
being low), side assist cannot be activated temporarily .

Audi side assist not available when towing
The radar sensor's view is limited when towing a trailer. For vehicles
with a factory installed towing hitch or a trailer hitch that was
installed later according to factory specifications, side assist is auto
