Th e text message ... (three white dots) appears if a setting cannot be

reasons:
• If you pull the control lever towa rds you to resume speed but no

• 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:

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 d istance 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 ig ht front trim grille
=> page 116,
fig. 113. 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

The text message Parking brake! appears if emergency braking was
manually initiated with the Electromechanical Parking Brake (EPB).
The adapt ive cruise control is turned off. This is accompanied by a

ESP activation
The text message ESP activation appears if the Electronic Stabiliza

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 below 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

[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 peda l "feels" harder.
• Adaptive cruise control is switched off after pressing the foot
brake. The speed saved up this poi nt can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever:::::,
page 120, "Turning adaptive cruise control off
temporari ly".
• 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 s ignal.
• If the speed you prev iously 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 128
• when vehicles in front are not in line with your vehicle:::::, page 128
• whe n other ve hicles are changing lanes:::::, page 128
• when other vehicles are difficult to detect:::::, page 129.
& 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!•

When the ignition is on, the backup lights illum inate when the
selector lever is moved into
R.
N -Neutral
The transmission is in neutral in this position . Shift to this position
for standing with the brakes applied~

When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the footbrake before and while moving the
lever out of
N.
D -Normal position for driving forward
Position Dis for normal city and highway driving. It ranges from zero
to top speed and all gears shift automatically, depending on engine
load, driving speed and automatically selected shift programs.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the
lever to
D out of N .
In certa in circumstances it may be advantageous to temporarily
switch to the manual shift program to manually select gear ratios to
match specific driving conditions~
page 152.
S -Sport position*
Select this position for sportier performance. In this position, the
transmission will not upshift as soon, allowing the vehicle to use the
increased power available at higher engine speeds to achieve livelier
acceleration . When the vehicle
is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the
