How is the speed stored ?
Fig. 125 Control lever:
Storing speed
With the system switched on the speed is stored as follows:
- Drive at the speed you want. The speed must be between
20 and 95 mph (30 and 150 km/hl.
- Press the
I SET I button ~ fig. 125 to store the desired
speed.
After the I SET j button is released , the current speed is stored and
maintained .
The saved speed is now shown in the LED display in the speedom ­
eter by one or two illuminated red light diodes=>
page 125. At the
same time, the saved spe ed is also shown for a short time in the
Information line::::>

For safety reasons, the stored speed is deleted when the ignition is
turned o ff . •

Setti ng distance
-Push the s lider switch onc e to the right 0 or to the left
0 ~ fig. 128. The distance currently set is shown for 3
seconds in the inst rument cluster display.
- Push the slider switch again to the right 0 or to the left
0 to increase or to decrease the distance by one step.
Selec t d ista nce
The distance at whic h the adaptive cruise control follows a vehic le
in front is determined by
time intervals. A time interva l to a vehicle
in front is established and maintained . This produces a speed ­
dependent interval. The higher the speed, the greater the safety
interva l in yards (meters) =>& .
The distances provided are specified values . These distances may
exceed or fall short of these target distances, depending on the
driving situa tion and the driving style of the vehicle ahead .
Dista nce 1 e::::,_e::::, __ _
This setting is idea l for brisk driving in bumper -to-bumper traffic.
T he distance is one second. This is the equivalent of, for instance,
• a dis tance of 36 feet (1 1 meters) at a speed of 25 mph (40 km/h)
Controls and equip ­
ment
• a distance of 72 feet (22 meters) at a speed of 50 mph (80 km/h)
• a distance of 108 feet (33 meters) at a speed of 75 mph (120 km/h)
Distance 2 e::::, __ e::::, __
This setting is ideal for "keeping pace" comfortably in bumper-to­
bumper traffic. The distance is 1.3 seconds. This is the equivalent of,
for instance,
• a distance of 46 feet (14 meters) at a speed of 25 mph (40 km/h)
• a distance of 95 feet (29 meters) at a speed of 50 mph (80 km/h)
• a distance of 144 feet ( 44 meters) at a speed of 75 mph (120 km/h)
Dista nce 3 e::::, ___ e::::,_
This sett ing is idea l for "keeping pace" in bumper -to -bumper traffic
and is the equivalent of the generally recommended distance that is
"ha lf of the speedometer speed" . The distance is 1.8 seconds . This
is the equivalent of, for instance,
• a distance of 66 feet (20 meters) at a speed of 25 mph (40 km/h)
• a distance of 131 feet (40 meters) at a speed of 50 mph (80 km/h)
• a distance of 197 feet (60 meters) at a speed of 75 mph (120 km/h)
Dista nce 4 e::::, ____ e::::,
This setting is idea l for secondary road traffic . The distance is 2.3
seconds . This is the equivalent of, for instance,
• a distance of 82 feet (25 meters) at a speed of 25 mph (40 km/h)
• a distance of 167 feet (51 meters) at a speed of 50 mph (80 km/h)
• a distance o f 249 feet (76 meters) at a speed of 75 mph (120 km/h)
You can set the way your vehicle performs in ACC mode when accel­
erating and braking in the rad io or MMI*
~ page 129. Depending on
the driving program and distance you select, your vehicle's acceler ­
ation and braking can range from dynamic (1) to comfortable (5). .,..

When setting the distance , the driver is responsible for adhering
to the respective national and country -specific regulations.
• 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.

(LED ligh ts).
Indicator light s (symbols )
• © Open road : The indicator l ight shows that adaptiv e cruise
control is active and that no object is ahead o f the vehicle. A stored
speed requested is maintained .
• @ Driv ing in traffic : The indicator light indicates tha t an objec t
has been detected traveling in front. Your speed is adjusted
according to the speed of the vehicle in front . The adap tive cruise
control acce lerates and brakes automatical ly within the system's
operat ion parameters.

means
Reque st for driver t o assume control. You as the driver must
slow the vehic le with the foot brake. The symbol tells you that the

system does not detect any objects over an extended time period.
For the time being, the distance to vehicles up ahead is not being

controlled . The ACC system is not switched off, so increased alert­
ness is required. The following may be reasons for the text message
ACC Functiona lly limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
react ing correctly, to veh ic les traveling ahead.
• I t is possible that you are driving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
signs, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message disappears .
The ACC sensor is located in the right front trim grille::::>
page 118,
fig. 122 . If there is a loss of operation due to heavy contamination,
this area should cleaned to restore proper operation .
ACC not available
The text message ACC not available appears , for example, if the
temperature of the brakes is excessive. Adaptive cruise control is
temporarily not availab le . A warning tone sounds as a reminder .
ACC not a vailable !
The text message ACC not ava ila ble! appears in the event of a
malfunction . Adaptive cru ise control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC sensor blo cked !
The text message ACC s ensor 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

!) or if it is only a temporary condition (ACC F unctionally
limited), the system wi ll a lso takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC senso r is dirty or b locked (e .g . leaves, snow).
The sensor should be cleaned to restore proper sensor function

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cruise con tro l is g overned by physical
and system -specified limits . Also, under certain circumstances, the
ACC system may react unexpectedly or late from the driver's point
of view. Therefore, always be attentive and intervene, if necessary:
• when driv ing around curves =>
page 130
• when vehicles in front are not in line with your vehicle
=>
page 131
• when other vehic les are changing lanes=> page 131
• when o ther vehicles a re di fficu lt to detec t=> pag e 131.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . Th is can result in vehicles driv ing ahead being in adequate ly
detected or, in some circumstances, not detected at all. If ne ces ­
sary , take a ction yourself! •
