& WARNING (co ntinued )
• Always turn off adaptive crui se control when entering turn
lanes, highway ex it lanes and con struction zones or similar situa­
tions because the vehicle will automatically accele rate to the
stored speed .
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being u sed because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detect s a situation when the brake s
must be applied.
• Alway s remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or something
else on or near the road that is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle .
• Always remember that the adaptive cruise control cannot
detect a veh icle th at i s driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and bicy­
cles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Ant i-Slip Regu ­
la tio n (A SR) c anno t be de activated when the adaptive cruise cont rol
is sw itched on .
If the ESP and the Anti -S lip Regulation (ASR) has been
de activ at ed an d yo u the n switch on the ad apt ive cruise cont rol, the
ESP fu nction w ill also be activated automatically.
• Dam age cau sed by accide nts (e.g. if the vehicle is dam age d whe n
park ing) can affect the rada r sensor settings. This can cause t he
sys tem to malfunc tion or switch off comple tely.
• The radar sensor cover is heated. In w inter conditions, you should
st ill ch eck befor e dr iv in g to make s ure i t is free of ice and s now. If
necessary, clean the area nea r the rada r sensor carefully=>

The different symbols for the time intervals appear if you change the
sett ings => fig. 123 .
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 d istance 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 ig ht front trim grille
=> page 116,
fig. 113. 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 Audi braking guard is active from a speed of approx. 20 mph
(30 km/h) and works within the system limits=>
page 12 7 even when
the adaptive cruise control is deactivated.
A radar sensor is built into the front of the vehicle=>
page 116,
fig. 113. 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 taken place, the system can assess a
hazardous situation, when a vehicle ahead suddenly brakes or when
your own vehicle is dr iving at high speed towards a much slower
vehicle ahead. As soon as the system assumes that a possible colli­
sion w ith the vehicle ahead can only be avoided by immediate all-out
braking or by an avoiding maneuver, a warning appears .
Th e system has a pre-set response time to be able to warn in good
time. This system response time is automatically reduced if you accel­
erate actively, for example to join a highway. Braking, transverse
acceleration and the steering angle can lead to a reduced system
response time. The warning is deactivated if you begin to overtake
with full accelerat ion.
The system draws your attention to two different hazardous situa ­
tions:
Distance
Th e distance wa rning is issued in the event of inadequate distance to
the vehicle ahead a period of more than S seconds. If the distance is
less than 30 feet (9 meters) at SO mph (80 km/h), for example, an
optical display is faded in on the instrument cluster=>
page 129,
fig. 132.
If the vehicle ahead brakes sharply, a collision cannot be avoided,
even in the case of an immediate response. In this case, increase the
distance to the vehicle ahead.
Speed
If there is a much slower vehicle ahead in your lane, or if the vehicle
ahead brakes sha rply, the Audi braking guard calculates the point from which a collision can only be avoided by all-out braking or by an
avoiding maneuver. If a warning does sound, a possible collision with
the vehicle in front can be avoided through an evasive maneuver or by
braking.
Th e warn ing is given in two stages:
• Pre-warning: An optical display appears in the instrument cluster
and a warning tone sounds.
• Acute warning: If you do not respond to the pre-warning, the
second stage, the acute warning, is issued. A brake jolt reminds you
to concentrate on the road again.
Under heavy breaking, brake assist =>
page 245 also helps you obtain
maximum braking effic ien cy.
& WARNING
Always pay attention to traffic, even when the Audi braking guard
is switched on. You are always resp onsible for
your speed and the
distance between your vehicle and other vehicles.
• Always keep the legally stipulated safety distance between
your vehicle and the vehicle ahead -danger of accident!
• The Audi braking guard does not respond outside the system
limits, for example if you approach a stationary obstacle (end of a
traffic jam or breakdown vehicle).
• Please observe that the Audi braking guard is subject to restric­
tions in narrow bends due to the field of vision of the radar sensor.
This may possibly lead to obstacles not being detected.
• The radar sensor's
vision can be reduced by rain, snow and
heavy spray . This can result in vehicles driving ahead being inade­
quately detected or, in some circumstances, not detected at all.
Always watch where you are driving.
• Reflecting objects such as e.g. crash barriers or the entrance to
a tunnel may impair the function of the radar sensor.•

There is a serious system malfunction:
• The program shifts only into certain gears .
• The engine may stall.
• It is not possible to restart the engine if it has been switched off.
• Continuing to drive could result in subsequent damage .

Sensors in the bumper
Fig. 169 Covered area
G:) and uncovered area
@ of the rear-view
camera
Fig. 170 Trunk lid:
Location of the rear­
view camera
Sensors are located in the front and rear bumpers. If these detect an
obstacle, audible and visual signals warn you . The range at which the
sensors begin to measure is approximately:
To the side
Center rear 2 ft (0.60 m)
5.2
ft (1.60 m)
The closer you get to the obstacle, the shorter the interval between
the audible signals. A continuous tone sounds when the obstacle is less than approximately 1 foot (0.30 meters) away. Do not continue
driving
farther.
If the distance to an obstacle stays the same, the volume of the
distance signal chime is gradually reduced after about
4 seconds
(does not affect the continuous signal tone). Approaching another
obstacle will cause the distance signal to sound again at the normal
volume.
Rearview camera coverage area
The MMI display shows the area covered by the rearview
camera => fig.
169 (D. Objects that are not in the area covered 0 are
not shown on the MMI display.
We recommend that you practice parking with the rear-view camera in a traffic-free location or parking lot to become familiar with the
system, the orientation lines, and their function . When doing this,
there should be good light and weather conditions.
In the MMI display, objects or vehicles appear closer or further away
if:
• you are driving in reverse gear from a level surface onto an incline,
or a downward slope,
• you are driving in reverse gear toward protruding objects,
• the vehicle is carrying too much load in the rear.
The accuracy of the orientation lines and blue surfaces diminishes if:
• the rear-view camera does not provide a reliable image, for
example, in poor visibility conditions or if the lens is dirty,
• the image on the screen is not visible due to sun glare and reflec ­
tion.
Caring for the rear-view camera lens
The rear-view camera is located above the rear license plate bracket.
F or the parking assist to operate, the lens=> fig. 170 must be kept
clean:
• Dampen the lens with a household alcohol-based glass cleaner,
and clean the lens with a dry cloth=>

to help reduce the risk of personal injury if the driver's airbag
inflates.
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way can cause serious injuries to the hands, arms and head if the
driver's airbag deploys.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli·
sion.
• Always sit in an upright position and never lean against or
place any part of your body too close to the area where the airbags
are located.
• Before driving, always adjust the front seats and head
restraints properly and make sure that all passengers are properly
restrained.
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle.
• Never drive with the backrest reclined or tilted far back! The
farther the backrests are tilted back, the greater the risk of injury due to incorrect positioning of the safety belt and improper
seating position.
• Children must always ride in child safety seats~

Proper seating position for the front
passenger
The
proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the seat
for the front passenger to the following position:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel=>& .
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it when ­
ever the vehicle is moving .
- Adjust the head restraint so that the upper edge is as even
with the top of your head as possible but not lower than
eye level and so that it is as close to the back of your head
as possible.
- Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly =:>
