& WARNING
• Following other vehicles too closely increases the risk of colli­
sions and serious personal injury.
• Setting short distances to the traffic ahead reduces the time
and distance available to bring your vehicle to a safe stop and
makes it even more necessary to pay close attention to traffic.
• Always use good judgment and select a safe following distance
for the traffic, road and weather conditions.
[ i) Tips
• Distance can be adjusted using the slider switch on the lever and
th rough

settings in the MMI menu are stored automatically and allocated to
the remote control key.

The desired speed set by the driver is displayed with a red LED.
Contro ls a nd eq uip­

The system al lows only speeds from 20 to 95 mph (30 to 150 km/h)
to be set. This speed range is faintly illuminated in the speedometer.

Cruise Control is active and that no object is ahead of the vehicle . A
stored speed requested is maintained .
• c::::,11 .. c:::, Driving i n tr aff ic: The warning light c:::,11«c:::, indicates that
an object has been detected travel ing in front . Speed is adjus ted

and brakes automatica lly.
• c:::,,, ,,c:::, Re quest f or driver t o assume control : The red flashing
warning light

You as the driver must slow the vehicle with the foot brake . The
symbo l

to s low the vehic le down enough to keep a enough distance to the
vehicle in front o f you . A warning tone signal wi ll also sound when
the symbol appears.
[ i ] Tip s
• If the Adaptive Cruise Control initiates braking, the hydraulic
brake system is under pressure. Therefore, the brake pedal distance
is shorter and the peda l feels "harder" .
• I f you use the accelerator to go faster than the speed being main ­
tained by the Adaptive Cruise Control, the system will not warn of
situations that require override of the Adaptive Cruise Control. No
warning light will appear in the instrument cluster display and no gong wil l sound .•

reasons
• If you pu ll the control lever forward to resume speed but no
requested speed was set.
• I f you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.

The text message AC C s en so r blo cked appears when the ACC
System does not detect any objects over an extended time period .
For the time being, the distance to vehicles up ahead is not being
cont rolled . The ACC system is not switched off, so increased alert ­
ness is required. The following may be reasons for the text message
ACC sensor blocked:
• The ACC sensor is dirty. The ACC system is not react ing, or is not
reacting correctly, to vehic les traveling ahead.
• It is possible that you are driving on a road with very light traffic
without any thing at the side of the road (e.g. guard rai ls, traffic
s igns, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message d isappears .
The ACC sensor is located in the area under the front license plate .
I f there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation.
AC C senso r bl ock ed!
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 chime sounds as a reminder.
To decide whether it is necessary to switch off t he ACC (ACC sensor

the system wi ll a lso takes into cons ideration the outside tempera -

Audi lane assist
----------------
I Not re ad y: The yellow ind icator light shows that the system is
t urned on but unab le to send a warning . 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 abou t 40 mph (65 km/h).
• The lane is narrower than about 8 ft . (2 .5 m), or wider than about
16
ft . (5 m).
• The curve is too sharp .
Notes on th e instr umen t clu ste r displa y
When the lane assist turns off automatically , the instrument cluster
indicator goes out and one of the following messages appears on
the display:
Audi lan e assist not available: C urre ntl y no se nsor vis ion
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 151,
fig. 169 is covered with dirt or ice. Clean this part of th e windshield.
• The camera v iew ing window is fogged up on the inside. In t his
case, wait until the fog disappears before turning lane assist on
aga in.
• 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 unti l the lines can
be more easily detected .
Audi lane assist not ava ila bl e
A temporary malfunction is preventing lane assist from operating .
Try turning on lane assist again a t a la ter t ime.
Audi l ane ass is t: sys te m f ault
T he system should be checked by an authorized Audi dealer or other
qual ified workshop .
[ i ] Tips
• Make sure that the camera viewing window => page 151, fig. 169
is not covered by stickers or similar objects .
• Always keep the camera view ing w indow c lean . This can usual ly
b e don e by op erat ing the windshield wipers. •

When driving through curves
Side assist cannot detect vehic les in curves with a turning radius of

Side assist's detection area is designed to cover lanes of standard
width to the left and r ight of your travel lane, depend ing on whethe r
you drive in the center of your lane or c loser to the edge .
I f you drive in narrow lanes, side assist's detection area may also
include other lanes - especially if you tend to dr ive on the edge of
your
lane~ fig . 182. Under these conditions, vehicles can also be
de tec ted tha t are two lanes away, and side ass ist then c ould switch
between the informational and warning stage signa ls.
When d riving in very wide lanes, vehicles in t he adjacent lane may
not be detected because they are not ins ide the detection area. •

Safety tips
The side ass ist detec tion may be li mit ed when dr iv ing a round
narrow street corners, on hilly streets, and under poor weather
conditions.
I t is possible that the radar sensors may a ls o detec t other objects,
such as high or staggered guardrails.
Side ass ist does not measu re actual la ne w idth. 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 driv ing 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.

To upshift
Push the selector lever forward to the plu s position 0

To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears
1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you apply a light thrott le when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you app ly a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear.
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic® wi ll downshift from the selected gear into
the next lower gear until it reaches 1st gear, based on road speed
and engine RPM. Automatic downshifting is interrupted as soon as
you apply the throttle again.
[ i ] Tips
• When you shift into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission will shift down
to a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic® is inoperative when the transmission is in the fai l-safe
mode .•
