OP-eration
The distance a t which Adaptive C ruise Co ntro l fo llows a vehi cle in
front is determ ined by
time intervals. A time interva l to a vehicle in
front is established and main tained. This produces a speed-depen ­
den t interval. The higher the speed, the greater the safety interval in
feet (meters) .
For example, if the interval
DISTANCE 3 i s 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 woul d be eq uivalent to a
distance of
131 feet (40 meters ) to the vehicle in front.
The distances given here are nominal va lues. The vehicle speed may
exceed o r fall short of these target speeds, depending on the driving
situation and the driving style of the vehicle ahead . .,

A pointer (arrow) is shown in this area. When slowly approaching a
moving vehicle detected ahead in your lane of travel, th is pointer
represents the distance to that vehicle . When approaching that
vehicle rapidly, it serves as early warning of an impending request for
the driver to assume full veh icle control. The pointer moves on a scale
from right to left.
Open road: With an open road and no moving vehicle detected up
ahead, no pointer is shown.
Driving in traffic: If a vehicle t raveling up ahead in your lane of travel
is detected, the pointer moves to the center area of the scale. This
area represents the time interval (distance) set.
It is shown in green
to make it easier to see .
Driver intervention prompt: Whenever the selected time interval
(distance) to the vehicle moving up ahead in your lane of travel is less
than the time inte rval (distance) set, the poin ter moves into the

System Limitations
Applies to veh icles: with Adaptive C ruise Cont ro l
General information
The radar sensor has limits that the driver must know to
be able to use ACC properly.
The Adaptive Cruise Control works within limits that are also related
to radar sensor range and sight distance. In some situations ACC may
react unusually or late from the driver's point of v iew. Therefore,
always be attentive to what is happe ning around you and always be
ready to intervene, if necessary:
• when driving around curves=>
page 139.
• when vehicles up front are not in line with your vehicle
=>
page 140 .
• when other vehicles are changing lanes=> page 140.
• when other vehicles are difficult to detect=> page 140 .
• when vehicles up ahead are no t moving or obstacles are in your
travel lane=>
page 141.
Con tro ls a nd e quip ­
m en t Vehicle
OP-eration
& 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 .
• Alway s pay careful attention to the traffic situation and be
ready to intervene and be ready to take complete control when ­
ever necessary .•

Not read y: The yellow indicator light shows that the system is
turned on but unable to send a warning. T his can be due to the
following:
• T here are no boundary lines, or there is only 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 const ruct ion sites) are
located in the vehicle's lane .
• T he veh icle's speed is below the speed needed to ac tivate it, which
is about 40 mph (65 km/h) .
• T he lane is narrowe r than about 8
ft . (2.5 m), or wider than about
16 ft. (5 m).
• Th e curve is too sharp.
Note s on the in strum ent clust er displa y
When the lane assist turns off automat ica lly, the instrument cluster
indicator goes out and one of the fo llowing messages appears on the
display :
Aud i lane ass is t not av ailable: Cur rentl y n o sens or v ision
T his message appears when the camera can no longer function
because it cannot detect the boundary lines. This may be due to the
following:
• T he exte rior side of the came ra viewing window =>
page 142,
fig. 157 is covered with dirt or ice. Clean this part of the windsh ield.
• Th e came ra viewing window is fogged up on the inside. In this
case, wait until the fog d isappears before turning lane assist on
again.
• T he system was unable to detect bo undary lines over an extended
period of time due to road co nd it ions (such as snow-cove red lanes) .
Do not turn lane assist on aga in until the lines can be more easily
detected .

moving over into the right lane.
Th e 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 147. 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 s ignal and side assist detects a vehicle in
a notab le location, the corresponding signal on the outside mirror
flashes briefly and brightly several times. This is the
