The distance at which the Adaptive Cruise Control follows a vehicle in front is determined by
time intervals. A time interval to a vehicle
in front is established and maintained. This produces a speed
dependen t interval. The higher the speed , the greater the safety
interval in feet (meters)
=> &..
For example, if the interval DISTANCE 3 is set, a vehicle in front is
followed at a
time interval of 1.8 seconds .
For a speed of
50 mph (80 km/h) this would be equivalent to a
distance of
131 feet (40 meters) to the vehicle in front.
The distances given here are nominal values. The vehicle speed may exceed or fall short of these target speeds, depending on the
driving situation and the driving style of the vehicle ahead.

In certain situations, the braking power of the Adaptive Cruise
Control is no t enough to maintain an adequate distance to the
vehicle up ahead . In these situations, the Adaptive Cruise Contro l
calls the driver to take action.
The
driv er in tervention pr omp t alerts you visually and audibly to
take over.

DISTANCE! appears in the status line .
• The indicator light~'" '~ in the speedometer b links red.
• A warning tone sounds .
[ i J Tip s
• If the Adaptive cruise control initiates braking, the hydraulic
brake system is under pressure . Therefore, the brake peda l distance
is shorter and the pedal "fee ls" harder .
• Adaptive Cruise Contro l 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 press
the control lever=>

• I f you use the accelerator to go faster than the speed of the
vehicle ahead of you, the

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. •
