Select distance
The distance at which the adaptive cru ise control follows a vehicle in
front is determined by
time intervals . A time interval to a vehicle in
front is estab lished and maintained. This produces a speed-depen­
dent interval. The higher the speed, the greater the safety interval in
yards (meters) ~
&-
Th e distances provided are specified values. These distances may
exceed or fall short of these target distances, depending on the
driving situation and the driving style of the vehicle ahead.
Distance 1 ~-~ ---
Thi s sett ing is ideal for brisk driving i n bumper-to-bumper traffic. The
distance is one second. This is the equivalent of, for instance,
• a distance of 36 feet (11 meters) at a speed of 25 mph (40 km/h)
Controls and equip ­
ment Safety first
•
a distance of 72 feet (22 meters) at a speed of 50 mph (80 km/h)
• a dist ance of 108 feet (33 meters) at a speed of 75 mph (120
km/h)
Distance 2 ,;::::,-- ~--
This setting is ideal for "keeping pace" comfortably in bumper-to­
bumper traffic. The distance is 1.3 seconds. This is the equ ivalent of,
for instance,
• a distance of 46 feet (14 meters) at a speed of 25 mph (40 km/h)
• a dista nce 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)
Distance 3 ~--- ~-
This setting is idea l for "keeping pace" in bumper-to-bumper traffic
and is the equivalent of the generally recommended distance that is
"half of the speedometer speed" . The distance is 1 .8 seconds. This is
th e equivalent of, fo r 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)
Distance 4 ~---- ~
This sett ing is ideal 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 of 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 acce ler­
ating and braking in the radio or MM !* ~

to the respect ive national and country -specific regulations .
• Following other vehicles too closely increase s the risk of colli­
sions and serious personal injury.
• Setting short distance s to the traffic ahead reduce s the time
and d istanc e av ailable to bring your vehicle to a safe stop and
makes it even more neces sary to pay clo se attention to traffi c.
• Always use good judgment and select a safe following distance
for the traffic , road and weather condition s.

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 distance 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 ight front trim grille=>
page 122,
fig. 112. 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

Engine speed !
The text message Engine speed ! appears in vehicles with manual
transmission when the driver did not shift up or down in time while
using adaptive cruise control braking or accelerating, causing the
vehicle to exceed or not reach the permitted limit speed. This causes
adaptive cruise control to deactivate automatically. A chime sounds
as a reminder .
Parking brake!
The text message Parking brake! appears if emergency braking was
manually initiated with the Electromechanical Parking Brake (EPB).
The adaptive cruise control is turned off . This is accompanied by a
warning tone.
Stabilisation program
The text message Stabilisation program appears if the Electronic
Stab ilizat ion Program (ESP) has inter vened. In this case the adaptive
cruise control is automatically turned off. This is accompanied by a
warning tone.
Speed
The set speed in mph (Canada km/h) always appears when saving or
changing the speed in adaptive cruise control~
page 125, "How is
the speed stored?" and~
page 125, "Chang ing stored speed".
Speed too low
The text message Speed too low appears if the current speed is too
low
to set or to hold the requested speed.
When setting a desired speed, it must be at least 20 mph (30 km/h).
At speeds be low 12 mph (20 km/h), the cruise control is turned off.
In speeds over 95 mph (150 km/h), the system remains active and
resumes the speed of 95 mph (150 km/h) if the driver removes the
foot from the acce lerator .
Selector lever position!
The text message Selector lever position! appears when the selector
lever is moved to position
N. In this position, adaptive cruise control
is not available. •

Driver intervention prompt
The driver intervention prompt calls on the driver to take
over the situation.
Fig. 123 Instrument cluster: Driver intervention prompt
In certain situations, the braking power of the adaptive cruise control
is not sufficient to maintain an adequate distance from the object
ahead. In this situation, the adaptive cruise control calls on
you as the
driver to take action.
The
driver intervention prompt alerts you visually and audibly. -.,

• A red vehicle is shown in the instrument cluster display
=>
page 132, fig. 123.
• The text
DISTANCE! appears in the status line .
• The indicator light in the Instrument cluster blinks red .
• A warning tone sounds.
[I) Tips
• If the adaptive cruise control initiates brak ing, the hydraulic brake
system is under pressure . Therefore, the brake pedal distance is
shorter and the pedal "feels" harder .
• Adaptive cruise control is switched off after press ing 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=>
page 126, "Turning adaptive cruise control off
temporarily ".
• If you use the accelerator to go faster than the speed of the object
ahead of you, the
driver intervention prompt will not be accompa­
nied by a warn ing signal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch off.•

General information
Some driving situations which affect the function of the
radar sensor are described below.
When driving, the adaptive cru ise contro l is governed 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, a lways be attentive and intervene, if necessary:
• when driving around curves=>
page 134
• when vehicles in front are not in line with your vehicle=> page 134
• when other ve hicles are changing lanes=> page 134
• when other veh icles are difficult to detect=> page 135.
& WARNING
The radar sensor's vision can be reduced by rain, snow and heavy
spray . This can result in vehicles driving ahead being inadequately
detected or , in some circumstances , not detected at all. If neces­
sary, take action yourself!•
